The 3 Best Updates For Modern Overhead Cranes

If you work in the material handling industry, your overhead crane is arguably one of the most essential pieces of equipment you use. The good news? It’s becoming easier and easier to increase an overhead crane’s lifespan.

This is all possible because various types of modern technology are making overhead cranes more productive. And, of course, the more productive they are, the more money you save.

The question is, are you taking advantage of these technologies, which are designed to add greater value to the lives of today’s crane operators?

Here’s a rundown on the three best updates for modern overhead cranes, and how they can take your work to the next level long term.

Upgraded Brake System

Updated brake systems remain one of the most in-demand upgrades among the users of overhead cranes.

That’s because the latest brake designs offer features like automatic adjustment, which helps to ensure that braking is balanced. It also ensures equal wear on your brake pads. As a result, you’ll prolong the life of your brake and reduce your maintenance costs in the long run.

Variable Frequency Drive

This type of drive offers ramped and smooth deceleration and acceleration when you use it on a hoist application, trolley application, or bridge application.

The result? Your motor will run cooler, which means more equipment control for you. Also, load spotting will be easier, and you’ll also experience softer equipment stopping and starting.

This feature additionally increases your brake’s life for the crane’s traversing direction. Specifically, a variable frequency drive will stop your motor and use your brakes for parking rather than stopping.

OmniPulse DDC

This microprocessor-based control is another must-have for the serious crane operator. 


Because it can improve your torque control and motor speed, in addition, it will lead to improved serviceability as well as minimized downtime.

Another benefit of this revolutionary update for modern overhead cranes is that it can reduce your maintenance expenses and energy costs. It will furthermore improve your safety.

6 Essential Wind Turbine Maintenance Tips

Do you or are you considering using wind turbines on your property to improve energy use? Are you looking for the best way to keep them running for as long as possible?

If so, then you need to know how to maximize wind turbine maintenance for the best performance. The goal is to keep all components operating regularly and keep a constant eye on turbines for any potential issues.

With our knowledge of manufacturing, your farm will get clean energy from your turbines for years to come.

Here are six essential wind turbine maintenance tips.

1. Stabilization

Maintaining wind turbines requires keeping the foundation and source of connection for parts stable. Issues that can increase the chances of your turbines falling apart over time include cracks in cement, loose bolts, and rusty spots.

You can deal with cracks by applying a cement sealing as soon as you notice them. With a reel for industrial wire, you will have a durable cable, keeping everything attached.

2. Lubrication

When it comes to how to maintain wind turbines, you need to keep moving parts in shape for consistent performance. Lubrication comes in handy for this situation, especially if you have an older wind turbine.

Check the oil and grease in your gearboxes and other parts for any metallic pieces. This will help you figure out which parts need lubrication and which ones need a replacement.

3. Electrical Components

Some aspects of wind turbine repair require extra care for the turbine’s operation and your safety. One example is checking on the electrical components, which requires locking the turbine from rotating and turning the external voltage source off before you begin.

Make sure that the cable is secure, and the controller unit isn’t damaged or running at high temperatures to prevent fires. You should also look at the ground connections so that they maintain their conductivity.

4. Bolts

Some components require more attention when maintaining a wind turbine due to their purpose and influence from the outside world. Bolts, for instance, are needed to hold the turbine together and may face challenges from the weather.

During your maintenance, look at the bolts to see which ones need re-torquing and remove debris that can hinder their function with rust. Give the bolts on the tower the same attention, and save bolt replacements for every few years.

5. Blades

Another part of the turbine that has to deal with weather and debris is the collection of blades. High winds, hail, bugs, and birds flying by can cause cracks, erosion, and lose connections over time.

Check your blades for signs of damage so that you know which ones need to be replaced. Smaller loads of damage can be corrected with custom skins for protection.

6. Remote Monitoring Systems

If you want to be extra safe about your wind turbine maintenance, then it may help to have a 24/7 remote monitoring system. You can keep an eye on your turbines at any time of the day for unexpected issues.

This system can come in handy for colder or wetter times of the year when you can’t work on the turbine in person. Your system should also have access to different parts of the turbine.

Our Take on Wind Turbine Maintenance

Wind turbine maintenance requires knowing what problems each of your components faces. With our tips, you can keep your turbines running for years.

5 Must-Have Crane Repair Services

Census of Fatal Occupational Injuries (CFOI) reports falling equipment or objects caused an average of 44 crane-related deaths per year in the U.S. 3/5 of these deaths

When was the last time your crane was inspected and maintained?

OSHA mandates regular crane inspections by qualified individuals. However, routine inspection and crane repair services aren’t just a safety concern. A major breakdown at the wrong time can affect your construction schedule. 

Worse, it could cost you far more than the cost of a small scheduled fix. Avoid inspection and regular minor repairs at your own risk.

Read on to learn more.

Regular Maintenance to Avoid Accidents

Crane manufacturers and OSHA recommend inspections based on time in use. 

OSHA and ANSI required crane inspections, performed daily and monthly, plus periodic inspections, performed monthly or annually are typical. However, most crane users opt for the absolute minimum scheduled crane inspections.

For example, instead of frequent inspection, they opt for quarterly. Where periodic inspections are suggested, an operator might haphazardly choose a cursory annual look. 

The Crane Manufacturers Association of America (CMAA) service classification, the use environment, and the duty cycle of a crane determine how frequently a crane needs maintenance. The duty cycle refers to lift frequency, the carry distance for loads, and the percentage of the crane’s capacity used.

The most efficient way to keep track of this information is online. A small transponder monitors and records this information for automatic crane repair services reminders and inspection alerts.

Crane Repair Services to Think About

Taking a crane out of service for an extended period is an expensive proposition. Here are five typical maintenance chores that can have dire results if skipped.

1.  Wire Rope Flaws

Birdcaging, corrosion, or internal core wear are all signs of an overdue inspection or crane repair services. Inspect the wire rope before every use. Regular lubrication reduces wear.

2. Alignment Flaws and Excess Wheel Wear

A crane skewing as it travels down the runway causes stress and damage to the entire crane system. This wears runway beams and wheels and destroys the working lifespan prematurely.

3. End Truck Wheel Wear

Through the course of a crane’s life, the wheels wear down due to normal use. Regular replacement prevents failure.

4. Hook Damage

Hooks are made with specific loads in mind. Incorrect loads or overloads place wear on parts not designed for carrying the stress. 

5. Electrical Wear and Tear

Contact interruptions between conductor bars and the collector or radio interference in the push-button pendant or radio controls signal the need for repair. Any breaks, no matter how intermittent, deserve a look. 

All of these conditions can be minor, but if ignored, can cause significant failures.

Maintenance Programs Save Money and Lives

Complete inspection records and frequent monitoring of small problems keep significant repairs and downtime at bay. They also happen to be required by law. 

Choose crane repair services that offer common-sense inspection and maintenance with high-quality, long-lasting parts. Want to compare replacement parts for your overhead crane?  Contact our experts today!

Finding the Right Machine Parts: Advice for Engineers

Do you source your machine parts from dozens of suppliers?  There are nearly 20,000 machine shops in the U.S. alone. Do you have to patiently explain what you need and why to a new person every single time? 

Industrial hoists and cranes, oil rigs, hydraulic lifts, etc. need maintenance. For some long-lived equipment, the original manufacturer no longer exists– what then?

Finding the right machine parts is challenging. You need a knowledgeable and innovative partner with a reputation you can trust.

Read on to learn more.

Off-the-Shelf Machine Parts

If the original manufacturer still supports your equipment, you can seek replacement parts through an authorized distributor. For example, if you need a Demag hoist unit, you have many choices. If you have many different types of machinery, you might end up with dozens of vendors.

Choose a dealer with experience in your industry to steer you to the right piece. Printed catalogs, online ordering, and toll-free calling are your friends. If you have machinery from many different vendors, an all-in-one distributor is especially convenient.

Original Equipment Manufacturer or Aftermarket?

Some types of equipment offer choices between OEM and aftermarket replacement parts. Obviously, your original manufacturer won’t offer a less expensive or more innovative aftermarket part.  For example, for mobile crane brake liners, you have a choice of interchangeable items. In the construction and agriculture industries, aftermarket parts have a reputation of exceeding OEM performance

Specialized, Customized or Re-Manufactured Parts

When you have needs outside of standard parts, you want a partner with custom fabrication skills. For many applications, a customized solution is the only answer. When that part needs repair or replacement, you need a partner with the know-how to reverse engineer and create the exact item.

Look for a vendor with a full-service machine shop in-house. Laser-cutting, milling, molding, and finish assembly are very different tasks and need experts at each step. A shop that can provide services in-house often has competitive pricing, as well.

Communicating your needs to multiple vendors can be tricky. Again, experience in your industry is the key to success. Choose a partner who knows your machinery well.

What are the Specific Industrial Braking Systems Used in Mining?

Industrial braking systems involves a process that is very “problem versus solution-oriented.” Those who run into problems on the job may report to an equipment distributor. The distributor then shares that feedback to begin working on solving it.

Sometimes the problem starting this chain of communication is from a flawed product. More often, it’s about finding better and more productive ways to get work done. These are just the necessary parts of an industrial mining braking system.

Mining brakes should be safe to use at all times. Any adverse performance traits of a braking system can have horrible consequences. Let’s look into what each type of brake requires.

Industrial Braking Systems in Mining

Mining brakes find their way into underground applications often. Some machines that do excellent above-ground work are not as great below ground. There are often more challenging operating conditions deep below the surface.

Some unseen bumps or holes cause a jarring impact and shock. It’s enough damage to destroy vehicles or their components seriously. Thick sludge build-up and moisture or airborne contaminants also contribute to damage.

Productive Braking Systems

Enhancing safety is a priority, but machine designers also focus on sustaining productivity. They get rid of any downtime in the industrial business by focusing on mining. And the mine operators prioritize on the cost-per-ton of material they use or produce.

Closed-center electrohydraulic brake valves, in particular, have their own purpose. They modulate the output pressure in proportion to its input current. This automatically ties these mining brakes to safety.

Engineers can facilitate braking features that help vehicle operators better operate. These enhanced features help them better navigate the difficult terrain of underground mines. This all increases productivity.

Using Electrohydraulics

Electrohydraulics are excellent aids for mining operations. Their features, like an automatic retard control, helps vehicles maintain speed. When vehicles work their way up and down inclines, this braking system keeps them at a steady pace.

Electrohydraulics also assist with load sensing. Even master equipment operators can make errors in judging loads. With load sensing, they can use electronic sensors to apply the brakes automatically.

Other mine vehicles can be used in especially hazardous areas. Instead of putting workers at risk, these machines work from a remote control. Electrohydraulic brakes can be used here when there isn’t an operator present.

Flexibility and Control

One of the hardest aspects of industrial braking systems is the lack of variation from mine to mine. As operators search for braking solutions, well-structured systems become more of a necessity. They look for a notably high level of flexibility and control to make their work successful.

You can program electronic signals to meet the demands of different job sites. This precise control helps with vehicle movement and is a big reason why electrohydraulics work. Having this control is excellent for any harsh and unpredictable conditions of underground mines.

Bottom Line

Reducing productivity and increasing safety is the end goal. Industrial braking systems that adhere to these priorities make for a successful operation. And no matter what, machines need these things to perform at their best.

How to Buy Workholding Clamps for Heavy Industrial Projects

Hydraulic workholding offers a wide range of benefits to manufacturers.

Faster clamping, faster machining, and improved part quality are only a few of the reasons why you should use hydraulic workholding clamps for heavy industrial projects.

If you’re not sure what kind of workholding clamps you need, we’re here to help.

Read on as we look at the main types of hydraulic workholding clamps and how they differ from each other.

Link Clamps

Link clamps are a great option if you need high clamping force but don’t have a lot of space.

The basic construction is a hydraulic cylinder that lowers onto the work to hold it in place. There are two main options: single action or double action.

Single action link clamps use hydraulic power when clamping down and a spring to retract the piston. Double action link clamps use hydraulic power to retract the piston also, making them better for fast usage.

Link clamps allow unobstructed loading. You don’t need to remove the clamps to load the next workpiece, speeding up processing times.

Pull Down Clamps

If you need to work on the surface of your material unobstructed, then pull down clamps are your best bet.

These clamps hold your workpiece firmly against the machine table or fixture. This is usually done by clamping through a slot or hole in the workpiece, allowing the clamp to hold it in place from below.

By clamping from beneath, the surface of your workpiece is free for processing.

Swing Clamps

Swing clamps offer the best of both worlds.

A hydraulic swing clamp allows you to clamp your workpiece in place without the need for any holes or slots that a pull-down clamp would require.

But unlike a link clamp, you can have full access to the workpiece for loading and unloading because a swing clamp has two actions. The arm will first rotate through 90 degrees until it is over the workpiece, and then clamp down, holding it in place.

Once the job is complete, the clamp will lift off the workpiece, and then rotate back through 90 degrees leaving the workpiece free to be removed unencumbered. These clamps can also be single or double action. If you’re running a high-speed manufacturing process, then a double-action swing clamp will speed up production.

Are You Looking for Workholding Clamps?

If you’re looking for hydraulic workholding clamps, you’re in the right place.

We offer hydraulic workholding clamps from all the biggest names in the industry, including Enerpak, Monroe, Vektek, Berg, Merkle, Hydrocomp, and more. If you’re not sure which products to choose, we can help with that too.

Contact Kor-Pak to discuss your machining and fabrication requirements, and we can help you choose between the best hydraulic clamp manufacturers. It will enable you to have a system ideally suited to your needs. Don’t forget to check out our other amazing products!

Container Crane

Container Cranes

Container Cranes, used at marine ports and rail yards, are usually container gantry cranes. The container cranes transfer shipping containers from marine vessels to dockside storage, or to rail & truck transport. The cranes are mobile, mounted on rails, or free moving wheels, while some are set on fixed pedestals.

 To handle the array of containers, these cranes are equipped with a spreader to handle a wide range of materials and containers. The spreader rides along the boom to hover over and descend to the container. The spreader lowers to the top of the container, and it locks into the four corner castings using a twist-lock.

 Container Cranes can be adapted for specific uses through the use of specialized accessories. Container Cranes vary in their capabilities. Most are equipped to transport a single container, but others can carry up to four 20 foot containers simultaneously. The cranes can handle up to several hundred tons.

 To ensure safe operation, the container crane’s braking system has to be well maintained.

Understanding the Precision and Process of Laser Cutting Technology

Laser cutting is synonymous with accuracy and cleanliness, especially in the technical fields in which it gets used. Equal parts versatile and reliable, laser cutting, works on various materials. It also boasts several unique advantages.

This has become the gold standard for precision, from automotive to semiconductor manufacturing, it all benefits from this adaptive manufacturing technology. And, today, we’ll learn more about the features and benefits of laser cutting and how it helps with applications across the board.

1. It’s More Precise Than Conventional Cutting

Manufacturers using laser cutting enjoy some practical benefits over traditional components. Much higher precision levels and quality than otherwise. This is the same across a variety of materials, all of which laser-based cutting has been proven to excel at.

Lasers provide consistent, precise cutting compared to traditional manufacturing techniques. This is for one specific reason. Unlike conventional techniques, laser cutting doesn’t need to make contact with the material. Conventional cutters take a certain amount of impact from excessive physical contact. Laser cutting, meanwhile, always creates a high-quality finish. These laser beams do not wear out during the laser cutting process. With that in mind, the level of precision and edge quality with the laser cutting machine is staggering in comparison.

Compared to conventional cutting, laser cutting technology allows you to cut more complex shapes. It does this at high speeds, and with very little damage or loss. 

2. Shorter Lead Times. Shorter Turnarounds

Compared to conventional manufacturing methods, laser cutting shortens lead times. Almost any size, shape, and type of material can be cut with a single laser cutter. This eliminates long lead times and setting up many pieces of equipment.

Faster processing times result when using laser services, besides the laser being able to handle large project sizes, as well. A high-quality machine can handle sheets that clock in at hundreds of square centimeters, as well as being thicker than you’d expect.

This further allows us to deliver smaller orders quicker and more efficiently. Allowing manufacturers to respond to market demand quicker than ever before.

3. Cut Materials of Almost Any Thickness 

As we’ve covered, laser cutting does not need to be in actual physical contact with the material being cut. This allows these lasers to perform precise work on materials of nearly any thickness or durability. All of this makes laser cutting ideal for small and specialized services, such as photoengraving.

Laser cutting can be used across dozens of materials and industries. This is enough to make it one of the most versatile materials for effective cutting, from large to smaller projects. And, as we’ve mentioned, laser cutting offers unparalleled precision and cutting quality.

Laser Cutting: A Mark Of Precision

There isn’t a construction technique out there that can outmatch laser cutting. Especially not when compared to its precision and cleanliness.

How to Determine the Ordering Specs for a Crane Hoist

An overhead crane hoist is a type of heavy equipment that’s used to lift and transfer heavy loads. They’re used in most industries, from agriculture and shipbuilding to mining and rail. 

A hoist and crane can cost anywhere from a few thousand dollars to a few hundred thousand dollars. Either price can be a huge business investment.

That’s why it’s crucial to know what to look for as you’re shopping around. Keep reading to learn how to calculate the ordering specs you need.

Lift Capacity

Every hoist will come with a capacity limit, which is the maximum amount of weight the hoist can handle.

To calculate the lift capacity you need, take a look at your business stats. How much does a typical load weigh at your company?

You should choose a hoist that will lift at 50% capacity. In other words, the hoist capacity should be twice the weight of the average load. This will ensure the safety and longevity of the hoist.

Lift Distance

The lift distance is the space between the hoist and the lowest area it needs to reach. The distance will determine how much vertical space the hoist can use.

To calculate this, measure the distance between the support beam and the floor. Then, subtract the height of the crane bridge. 

The lift distance will help the crane manufacturer decide what size you need.

Lift Speed

The lift speed is how fast the hoist will be able to pull loads up and release them down. Just like with vehicles or other heavy equipment, hoist motors are measured in horsepower. A horsepower is a measurement of pulling power, distance, and time. 

The higher the horsepower a motor has, the more expensive it will be. So, when calculating the lift speed, you need to consider the needs of your business.

If your operation needs to move heavy materials quickly, you will probably need a large motor. But if you infrequently move light materials, you could get by with a smaller motor.

Power Supply/Voltage

Hoists need electricity to pull loads. They can come in voltages of 115V, 230V, or 460V.

When shopping around for a hoist, it’s essential to know what your current electrical system can handle. You may need to call an electrician or refer to the building plans.

Choosing a crane system that is compatible with the electrical system you already have can save you a lot of money.

Crane Span

If you are installing the overhead crane at an indoor facility, you have to make sure it will fit. The span of a crane is a measurement of the distance between the runways.

If you’re ordering a new crane, measure the distance between the support beams where you plan to install the crane. 

Choose Kor-Pak for Your Hoist and Crane Needs

Did you know that an overhead crane can last for up to 80 years? So, you might not need a new crane after all. An upgrade or a modernization might be all you need to make your operation run smoother.
