Overhead Crane Inspections: How, When and Why?

In 1989, a construction crane collapsed in San Francisco’s financial district, causing five fatalities and 19 injuries. Experts blame a lack of regulation.

Serious crane-related disasters are always a moment to reflect – what went wrong? More importantly, how can we prevent this from happening again?

Since 1989, Occupational Safety and Health Administration (OSHA) regulations have improved. Unfortunately, crane accidents still happen. In 2008 alone, there were 72 fatal crane-related accidents.

How can employers prevent these high-cost accidents from happening? That’s where routine overhead crane inspection comes in. Check out this guide to make sure you’re meeting your essential crane inspection requirements.

Why Inspection

Humans rely on machines to complete a seemingly endless array of tasks that society depends on. These machines are primarily reliable, but still susceptible to regular wear and tear. Human bodies can break down from extended periods of heavy use, and so can the nuts, bolts, and mechanisms of our most trusted machines.

That may seem obvious, but the federal government holds organizations accountable to that fact. That is why they uphold OSHA regulations for the regular maintenance of these machines. Cranes are also included in their ordinances.

Regular overhead crane inspection will improve the human safety conditions in your facility. It will decrease your accident liability, boost your equipment reliability, and keep you OSHA compliant as required by U.S. law.

Who Can Inspect

The Crane Manufacturers Association of America (CMAA) recommends that you have crane inspections conducted by an inspector with a minimum of 2,000 hours of experience.

The inspector should be able to demonstrate and provide proof of their experience in the practical areas of maintenance, servicing, repairing, modifying, and testing crane function. They should also be able to demonstrate and provide proof of their formal education in the field, including in-depth knowledge of the states and federal regulations.

How Often to Inspect

This is where things get a little complicated.

There are four categories of overhead crane inspection. It’s advisable to keep a schedule so you can track your compliance with these regulations.

Initial

When first purchasing new crane equipment, whether, for the first time or repair, every item must be tested.

According to OSHA, ” Prior initial use, all new and altered cranes shall be inspected to ensure compliance with the provisions of this section.”

Functional Test

OSHA also mandates that crane equipment should be visually inspected on a daily basis, before the beginning of use.

There should be a record of checks for leakage, wear and tear, maladjustment, deformation, and deterioration, usually conducted by the crane operator. The more complicated inspections can be conducted monthly.

Frequent

Unlike the functional testing record, these do not need to be as meticulous. Still, they should be documented depending on the use of the equipment.

Inspect heavily used cranes daily to weekly, moderately used cranes weekly to monthly, and lightly used cranes monthly.

Periodic

These inspections are much more thorough, and thus, are not as frequent. Lightly and moderately used cranes can be inspected yearly, while heavily used cranes must be inspected quarterly.

Even if a crane has not been used, it is required to have periodic testing before its next use.

Overhead Crane Inspection

If your organization does not meet OSHA’s overhead crane inspection requirements, you could be fined thousands of dollars. In case someone is injured, you won’t just lose more money, but there may even be a loss of life.

Routine crane inspections serve a very important purpose. Contact us today to see how we can help you integrate these procedures into your organization as smoothly as possible.

Switching From a DC to AC Crane Motor? What You Need to Know

Trying to decide if you should switch from DC to AC?

Before you make the decision, you have to know the difference between DC and AC motors and what kind of benefits they give you.

Take a look at this guide to find out if you should make the switch.

DC vs. AC Motors: What’s the Difference?

The main difference between these motors is the current they use.

For example, DC motors are power because they take direct current electrical energy and change it into mechanical energy. AC motors do the same thing; only they use an alternating current to draw their energy.

But what does this mean?

Well, let’s break it down.

DC Motors: These motors change the current’s direction by using a commutation ring, a system of carbon brushes, and a rotating armature. The motor has several magnets inside of it that make the motor turn by interacting with a rotor.

AC Motors: There are two different types of AC motors; one is an induction motor, and the other is a synchronous motor.

The induction motor gets power from the input voltage by using a serious of coils. This makes a stator field, and that powers the rotor field.

The synchronous motor creates a magnetic field by using either slip rings or magnets, which is called a precision supply frequency.

From DC to AC: Is the Switch Worth It?

Some benefits come with making the switch from DC motors to AC motors. So, in short, getting AC upgrades is worth it.

We’ll take a look at some of those benefits and find out how they can save you a lot of money and hassle in the future.

But first, let’s look at some of the downsides that come with DC motors.

The Downsides of Using a DC Motor

DC motors may be effective, but they are also older than AC motors. With age comes complications.

As more and more people switch from DC to AC, DC technology is getting harder to come by. Some types of DC technology aren’t available anymore at all, so making repairs to your DC motor can be time-consuming and difficult.

Even if you find a place that can make the DC technology you need, it can take several months to build. In the worst cases, you can wait for nearly half a year for the right parts.

If your company depends on a DC motor, a seemingly simple repair can stop your progress for a long time.

The Benefits of Using AC Motors

AC motors are newer, have lower HP, and use significantly less amperage than DC motors. This means they use a fraction of the power DC motors use. In most cases, making AC upgrades will cut your energy consumption and attendant costs nearly in half.

AC motors have more available technology at much lower prices, and they can include new safety features.

Because of this, you’ll probably find AC motors last longer than DC motors as well.

What to Know When You’re Making the Switch

The biggest drawback of switching to AC motors is a lack of AC power supply. But if your facility is to run on AC power it will save you money in the long run.

Do You Need New Industrial Brake Hardware?

According to Joe McIsaac of Carlson Quality Brake Parts, “Most hardware is already removed when your pads and rotors are replaced, so it only takes a few extra minutes to install new hardware instead of replacing the old, worn parts,”

This has been a huge debate in the machine world, replace or keep old parts.

Here are just a few ways to tell when your brake hardware is going bad, and why it’s wiser to replace everything.

What Causes The Brake Hardware To Go Bad

No amount of lubricant or grease can make up for bad hardware. No matter how often you try to delay the inevitable.

You end up saving money in the end by simply replacing the hardware. A fresh set of hardware gains you horsepower and reduces drag.

Constant heating and cooling cause your springs and rattle clips to weaken. What you get as a result is excessive movement, binding, pulling warping uneven wear, and unwanted noise.

How Do You Know If They Need To Be Replaced

There are several factors that you need to take into account when deciding if you need to replace your brakes.

Your Production Has Changed Or Increased

Sometimes your production patterns change. This isn’t an unusual phenomenon, and when this happens, even your best equipment will need to change with it.

You might be required to add on weight and heavier materials that your equipment isn’t strong enough to handle.

Not only may you be adding more weight, but you may be adding to how much you use your machinery per hour.

All of these factors can cause your brakes to wear, and if they entirely give out, it may become very costly to fix the issue.

Replacement Parts May Become Fairly Difficult To Obtain

The older your machinery gets, the harder it becomes to find replacement parts. This is a nature of the beast.

If you keep putting off finding new parts, it may become more difficult and expensive to find them later on down the line.

In this case, it might be best to go ahead and replace all of your parts rather than just the breaks.

This ensures that you have your parts and you won’t have to kill yourself looking for them later.

You’re Having To Make Repairs Frequently

If you find you are continually making repairs, it might be time to replace the brake system.

If you have to keep doing repairs on your machines, it becomes more costly than just replacing the hardware because productivity dies when the machine is always down.

You might think a little grease might do the trick or keep putting it off, but replacing the Hardware is best in the end.

Replace the Parts Vs. Grease

Many think that a little grease rather than replacing the brakes is the best option. However, it is not.

Automotive labs have proven that replacing the parts rather than using grease to prolong the inevitable has increased performance and reduced brake noise by a large margin.

If you just keep trying to fix the old equipment with grease, your system will eventually give out and be more expensive to fix later.

Don’t Put Off Replacing Your Brake Hardware

When you put off replacing your brake hardware, you run the risk of destroying your whole system.

Trying to save money by not doing these replacements will just cost you more in the end. Look for signs and solve the problem before this happens.

The Different Industrial Braking System Options

Motors, hoists, cranes, vehicles, and even wind turbines all have industrial braking systems as central components.

It’s key to understand the different types of brake calipers and brakes in your equipment. This way, you can easily identify problems and ensure quality maintenance.

Here is a short guide to the different types of industrial braking systems.

Brake Caliper Purpose

The purpose and function of brake calipers in a disc brake system are to slow the vehicle’s wheels by creating friction against the rotor.

The wheels attach to the rotor. By generating friction to the rotor, you apply friction to the wheels, thus slowing down the vehicle. This is how a brake caliper works.

Types of Brake Calipers

These are the different types of brake calipers that make up most industrial braking systems. They include pneumatic, hydraulic, and pneumatic spring-applied brakes.

They also include hydraulic spring-applied brakes and dual function mechanical/hydraulic brakes.

Industrial Braking Systems

Industrial braking systems come in some basic types listed below. Some vehicles and other equipment may have a combination of these types.

AC Disc Brakes

Electrohydraulic disc brake types FBT and FPT are spring-applied failsafe brakes. They act on a disc. Like AC Drum brakes, AC disc brakes release from the turbel, which is an electrohydraulic device.

The brake shoes on AC disc brakes have asbestos-free linings. The main shafts are stainless steel with self-lubricating bushes. Disc brakes also have a torque scale.

AC disc brakes have a self-adjusting system for arms and brake shoes. The design is symmetrical. Finally, they also have an eccentric transmission system, which makes them lighter, simpler, and require less maintenance.

AC Drum Brakes

Electrohydraulic drum brake types NAT, NDT, and NFT, are spring-applied, failsafe brakes that act on a drum. The brake releases via an electrohydraulic turbel. The turbel is a three-phase, AC electrohydraulic thruster.

In conventional models, the turbel is configured vertically (a linear shaft brake) or horizontally, as in the NDT-A models. The braking torque is adjustable, and the brake has an optional torque scale. With NDT-V models, the torque scale is standard.

The brakes have stainless steel shafts, and brake joints with self-lubricating bushes. The brake shoe linings are asbestos-free.

Some AC drum brakes have additional options, such as automatic lining wear adjustment and an open brake switch indicator. Other options include a lining wear detector, a hand-release lever, and reduced torque.

They may also have a pneumatic or hydraulic release, or progressive braking, made possible by a descent valve in the thruster.

DC Shunt Brakes

Electromagnetic drum brakes are brakes that work on a drum. They release by an electrically-applied spring. The brake releases through a DC-operated magnet.

Some manufacturers also offer mixed brake systems. They are a combination of the DC shunt and a hydraulic override pedal.

Emergency/Failsafe Brakes

NHCD series are the hydraulic emergency or failsafe brakes. They are spring-allied and hydraulically-released. NHCD brakes are for applications like cable drums and conveyors. A hydraulic unit must connect to them to work.

Each emergency brake has two half-calipers symmetrically mounted at each side of the disc’s central line. The springs determine the clamping force of the brake.

NHCD brakes can come with options that include an open brake switch indicator and a lining wear detector. They can also come with various sets of hoses and fittings as well as fixing bolts and brake brackets.

How Are Cranes Built? Your Guide to Crane Creation

Cranes are a crucial part of the construction process. Primarily known for lifting and moving heavy objects, these machines have been around since the ancient times.

Let’s take ancient Egypt for example. Back in the day when they wanted to transport water up, and down the Nile River they used a crane called a shaduf.

This crane consisted of a bucket/weight system where the user would pull the bucket down on one side and allow the heavyweight to pull the bucket up on the other side.

Thanks to technology, modern cranes don’t require that much arm work. With a push of a button, heavy objects are now lifted and placed precisely how where you need them.

So the question is: How are cranes built now? How did we evolve? Let’s take a look.

Let’s Talk About The Basics: How Are Cranes Built?

What does it take to construct one of these monstrous machines? How are they able to work so effectively?

Depending on the size, a crane can weigh anywhere from 10 tons to 300 tons and can hold up to 400,000 pounds. So when it comes to the crane structure, clearly every manufactured part is vital to make this move and lift exactly how it’s supposed to.

1. Making Steel Components

When it comes to figuring out how cranes are made, steel is the essential material in the manufacturing process. Melted iron is taken through a furnace where carbon is removed via the oxygen blasted in the liquid.

Much like the welding process, the steel is melted and molded in high temperatures to form flat sheets, rods, and bars that make up the crane material.

2. Assembly

After the components are intricately cut and formed – it is then moved into an assembly line where the welding and bolting process begins.

Different cranes require different types of machine operation. For instance, a mobile crane is usually assembled to the blueprint of a truck or crawler. Contingent upon the size, the cranes may either be assembled in the factory or broken down and put together on site.

3. Quality Check

Every single crane has to go through a quality check inspection. Assuring the security of the crane is one of the most important factors in this process.

From the largest sheet of metal to the smallest cable, these pieces arrive at a crane manufacturer where they go through lathes, drills, and precision machinery where they’re shaped to form mobile crane parts, hoists, and other important parts that make up the crane design.

The Different Types of Oil Drilling Rigs

Drilling rigs are essential to the oil and gas industries because of their ability to extract petroleum from the earth’s surface. There are many types of drilling rigs, used in both offshore and land-based drilling. The type of oil rig selected for a particular job depends on the specific requirements of the site.

Both offshore and land-based rigs bring in large amounts of oil, though offshore rigs tend to come to mind when you think of an oil rig.

Let’s take a closer look at the different types of drilling rigs, how they are designed, and their uses.

The Different Types of Drilling Rigs

An oil drilling rig extracts petroleum from the earth. But there are different types of drilling rigs. Here’s your guide to know which rig your company needs.

Jackup Rigs

Jackups are the type of drilling structure most often used for offshore operations. The main deck is supported by a series of open-truss legs that extend up to 350 feet to the ocean floor.

Some jackup rigs are known as a keyway or slot-type rigs, which have an opening in the drilling deck, with a derrick positioned over the opening. The second type of jackup is known as a cantilevered jackup, with the drilling derrick mounted to an arm that extends out from the deck.

Floaters

This type of offshore oil drilling rig is semi-submersible units that float on giant pontoons or hollow columns that can submerge the rig to the needed depth when filled with water. Floaters are typically used for drilling new wells because of their ability to withstand rough ocean conditions.

Fixed Platforms

These types of oil platforms are permanent, immobile cement structures, used to house drilling rigs that open new wells. Fixed platforms are connected to the ocean floor, and are large enough to house crew and equipment.

These are mostly found in great depths, up to 1,700 feet, such as on continental shelves, and can use a drilling technique called directional drilling, allowing them to be attached to numerous wells within a five-mile radius.

Complaint Towers

Similar to fixed platforms, complaint towers consist of a narrow tower supported by a piled foundation, and a conventional drilling deck. Because of its narrow and flexible design, a complaint tower can withstand tremendous forces sustaining great lateral deflections in depths from 1,500 to 3,000.

Drillships

Typically built on tanker hulls, these merchant’s vessels are designed for use at great depths for scientific drilling purposes. These vessels look similar to tankers or cargo vessels, but drillships are equipped with a drilling derrick and a helipad for receiving supplies and transporting staff.

Drillships are mobile, able to propel themselves from location to location.

The Importance of Oil Rigs

Each of these types of drilling rigs is vital to the production of oil and gas. Crews work around the clock, every day of the year, pumping petroleum from the earth for countless purposes, for both industrial and consumer uses.

It’s a complex, fascinating industry that impacts your life in more ways than you could imagine.

Your Guide to Overhead Crane Safety

Overhead crane safety is of paramount importance. The statistics speak for themselves. For example, the U.S Bureau of Labor Statistics, reports that between 1992 and 2006, 632 deaths occurred because of crane accidents.

Although safety measures have improved over the last decade, the fact remains that health and safety standards in this arena need maintaining.

In light of this, we’ve compiled a mini guide to overhead crane safety. Hopefully, this will help minimize the likelihood of you and your employees experiencing any accidents on the construction site.

Complete a Safety Checklist Before Operating Cranes

If you don’t have a safety checklist in place, then we recommend drawing one up and completing it before operating a crane.

Here are a few things to include:

  1. Check for any loose materials (packaging, parts, etc.) and remove them before operating the crane.
  2. Always check the load’s maximum capacity weight and ensure the amount doesn’t exceed this limit. This information is usually marked on the outside of the crane, so it’s pretty easy to familiarize yourself with this.
  3. Always remove visible slack from the hoist or sling before lifting.
  4. Ensure the space between the equipment and the loading destination is clear of any hazards or dangerous components that could obstruct the lift.
  5. If you’re working alongside colleagues, let them know when you’ll use the crane, what you’re moving and where you’re planning on using it.
  6. If you’re helping to load the transfer, make sure you and your coworkers position yourselves so you can see the load without putting yourselves in harm’s way.

By executing these preliminary safety measures you drastically increase the likelihood of having an accident-free transfer.

Things to Avoid While Operating an Overhead Crane

We recommend always avoiding the following while operating an overhead crane:

  • Never use a crane if the limit switches are either down or out of order.
  • Never allow yourself to become distracted during the move. You should watch the load at all times; focus is of paramount importance.
  • Never lift a load from a sideways angle. Always aim to center the weight before hoisting. This helps to reduce swinging during the transfer and makes the process safer and easier to control.
  • Don’t under any circumstances allow people to ride on the load during the transfer.

Be sure to follow all of the above advice, stick to these pointers and hopefully you shouldn’t go too far wrong.

Your Guide to the Industrial Disc Brake Caliper

Without the invention of the industrial disc brake caliper, many industries just wouldn’t be what they are today.

Industrial disc brakes are essential to the operation of a number of industrial applications.

Their function governs the operation of many sectors, including the agricultural, mining, energy, oil and marine, and manufacturing industries.

Industrial disc brakes are manufactured in many forms, each suited to their own application and industry.

To learn more about the various industrial disc brake calipers on the market today, this blog highlights it all.

Industrial Disc Brake Caliper Applications

No matter the industry or application, all caliper disc brakes work to achieve the same end goal: to slow, hold, or stop fast moving or heavy loads.

Some caliper disc brakes are designed to achieve this very quickly, while others work in slower motion.

Caliper disc brakes offer the ultimate safety solution and are designed to withstand extreme tension associated with dynamic braking.

Industrial disc calipers are capable of withstanding the most aggressive of conditions, extreme temperatures, locations, and volatile environments.

Some of the most common industrial applications for caliper disc brakes include:

  • Industrial manufacturing
  • Mining
  • Oil and gas extraction
  • Energy production
  • Entertainment
  • Shipping and transportation

As we mentioned, there are various different types of industrial disc brakes, some of the most commonly used include:

Mechanical Disc Brake Caliper

Mechanical disc brake calipers work at the most simple level of the braking system. They are generally operated by a lever, and require no external power source.

Mechanical brakes are most commonly found in common vehicles, such as your car, operated by a handbrake.

They are best-suited as a safe stopping mechanism within most industries.

Pneumatic Disc Brake Caliper

These caliper disc brakes are powered by compressed air, making it a highly popular braking system across many industries.

The source of power is readily available due to the fact that many industries make use of pneumatic compressors throughout their business.

This braking system is used to slow or bring rotating parts to a complete stop, operating at 70-120 PSI.

Hydraulic Disc Brake Caliper

The hydraulic disc braking system is powered by compressed fluid, known as hydraulic oil across many industries.

Hydraulic brakes operate under immense pressure and are best-suited to holding, stopping or tensioning extremely heavy or fast-moving machinery.

This is also known as high torque braking, and is most commonly used in the mining, oil and gas industries.

Spring Applied Disc Brake Caliper

Unlike a hydraulic braking system which uses direct pressure, this system uses a spring to apply direct pressure onto a moving part.

This system is also known as a ”fail-safe” braking and is highly common in industrial settings.

Stopping, slowing and braking is maintained by the braking system, until the spring is released and parts begin moving once again.

Dual Function Disc Brake Caliper

This dual function braking system combines both mechanical and hydraulic braking force onto a moving or rotating object.

Essentially, this system offers double the amount of braking torque.

However, some pieces of equipment will include separate bores for either the mechanical brake system or hydraulic brake system.

Tips for Every New Crane Operator

After extensive studying and hands-on training, you’re now officially a crane operator. Congratulations! You’re entering a promising new career.

Here’s why.

Research shows that jobs for material moving machine operators, such as the operators of cranes, will grow by 6% between 2016 and 2026.

Of course, even after training, operating a crane can be intimidating. If you’re a new crane operator, here are some tips to prepare you for your brand-new career.

Let’s get started!

Your Crane Operator Environment

When it comes to operating a crane, safety is your number-one priority. Always.

Therefore, for starters, make sure that your job site can support your crane and future loads before you get set up.

Also, be cognizant of any overhead hazards present in the area where you’re working. Specifically, make sure that power lines and nearby buildings are not in the way within your operating zone.

Along the same lines, continually survey your surroundings to see if your job site’s conditions have changed. Even a slight change may require you to change how you operate your crane. These changes may have to do with personnel at the site or even weather conditions.

Also, just as with cars on the road, avoid using your cell phone while you’re operating a crane. It’s a dangerous distraction that has no place in your crane’s cab.

Your Planning

Before you turn your crane’s key, take time to review your equipment’s load chart. This chart essentially specifies how your crane’s lift capacity differs based on factors such as a certain angle and distance. By planning, you ascertain that you have enough capacity to complete your job.

Also, be flexible. Your plans could change from time to time. In fact, they probably will.

For instance, in some situations, you’ll have to stop and evaluate your lifting situation. If the situation calls for it, you’ll need to develop a safer lifting plan before proceeding with your job.

Your Equipment

One of the biggest mistakes you can make as a crane operator is to overload your crane. Overloading your crane may lead to serious problems, particularly if your machine’s line is strained. In the end, the line may break.

Also, make sure that you’re using the proper cribbing and pads. Otherwise, an outrigger may sink or fail while you’re trying to make a lift.

Finally, before you embark on a job, don’t overlook the basics of crane maintenance. For instance, check your machine’s fluid levels, including the oil and gas levels, to make sure that you are not low.

Also, regularly inspect your crane equipment. You just may end up spotting hydraulic, structural, electrical or mechanical issues that could spell significant problems down the road if not resolved right away.

How We Can Help

We offer high-quality services that every crane operator will need at some point, ranging from crane modernizations/upgrades to overhead crane inspections.

A Guide to Custom Brake Shoes and Pads for High-Speed Rail Applications

Newer braking systems are in place to ensure the safety of people and freight with the advent of high-speed rail.

A strict policy of systems maintenance and replacement is necessary. Passenger and freight safety require it at the higher speeds. Regenerative braking is added to the standard automated pneumatic brake. This results in shorter braking distances.

When speeds are high, the energy of pneumatic braking is dissipated as heat. High heat applications require specialized custom brake shoes and parts. Read on for a quick rundown.

High-Speed Train Braking Systems

The high energy values of braking at high traffic speeds wear brake linings and discs far more than conventional rail speeds. High-speed trains use dynamic brakes. They don’t rely on direct friction force in combination with automated pneumatic brakes.

The electric brakes redirect high braking forces into the rail or stored for regenerative use. This includes dynamic and recuperative braking, eddy-current brakes, or hydro-dynamic brakes, etc. The high energy values of braking at high traffic speeds wear brake linings and discs far more than conventional rail speeds.

Remaining energy is absorbed by the conventional friction braking system and dissipated as heat. Technical specifications for different rail cars require brake shoes adjusted to each car. Custom brake shoes appropriate to the type of wear, speed, and conditions of use reduce the need to disassemble and change brakes frequently.

Custom Brake Shoes and Pads

Specifications for passenger cars detail the amount of air gap and brake pad that must remain. The technical documents also detail certain brands or their equivalent. Performance of brake disc pads must be suitable for the speeds,

duty, and performance.

Brake shoes must also be suitable for the speed, duty, and performance expected. Composition brake shoes 2 inches thick and of a size and type in general use are specified. Custom brake shoes of the appropriate thermal resistance will improve wear.

Freight and passenger applications require different types of shoes. Let one of our representatives walk you through low and high friction applications as well as tread conditioning shoes.

Right Products for Your Application

Kor-Pak has a large selection of friction materials to meet the requirements of almost any rail application. Kor-Pak meets the requirements of several major rail companies worldwide.
