How Does a Disc Brake Work? A Complete Guide

Long considered the best option in braking technology, disc brakes are frequently used in many industrial machines. But how exactly do they work?

Read on for an overview of how a disc brake works and some disk brake tips for buying disk brakes. 

Anatomy of a Disc Brake

There are three main components of a disc brake. These are the brake pads, the rotor, and the caliper. In addition, other components work with these three parts to ensure the disc brakes work correctly.

Other components include the piston that connects with the caliper, the hydraulic system for the brakes, and the wheel itself that the brakes are working to stop.

Your disc brakes guide will probably show that your brakes are vented. Most of these brakes are vented to help keep the braking system cool. Sets of vanes pump air through the disk, making sure things don’t overheat or wear out.

How Do They Work?

When the brake is pushed on a machine, it pushes hydraulic brake fluid through lines to the brakes. The fluid moves pistons, which then close the calipers.

These calipers attach to the brake pads, and when they squeeze shut, the brake pads then press against the rotor. This creates a lot of heat and friction, slowing the machine down or stopping it completely. However, as opposed to other types of brakes, disc brakes wear down evenly across their surface, which means you won’t have to replace them until the entire brake pad is worn out.

Because of this, brake pads are designed to handle that excessive heat and friction while still providing enough friction themselves to stop the machine. They are made of various friction materials, depending on the type of brakes and the purpose of the job.

Buying, Repairing and Replacing Disc Brakes

Disc brakes are not always the go-to brake system in industrial machines, but they’re increasingly used in factory settings. The good news is you can order brake parts and have them installed on your machine with little difficulty. In the same way, you can order replacement parts if your pads wear down or your brakes wear out.

Choosing disc brakes is easy because there are so many high-quality industrial disc brakes and brake manufacturers to pick from. Some firms specialize in brakes for oil, gas, and energy industry machines, while others focus on transport and hauling machinery. You can look at different companies to see what sizes and types of disc brakes they specialize in and determine which style would work best for your situation.

How a Clutch Works: A Complete Guide

Did you know that there are more than 45,000 industrial machinery and equipment manufacturers in the U.S. alone? With that many manufacturers, there are countless more industrial machines that use clutches to perform their essential operations.  

Read on to learn how a clutch works. 

How a Clutch Works

A clutch is a bridge between two rotating shafts, one shaft is typically connected to a motor, and the other is connected to another device. For many industrial machines, the other device is the drive shaft.

The clutch is the mechanism that allows the two shafts to either be connected or disconnected. When connected, these two shafts are running at the same speed. When they are disconnected, the motor is still running, but the machine is idle to allow for pauses in work

Different Types of Clutches

Multiple types of clutches offer different advantages. The following is a clutch guide to the major types.

Friction Clutch

A friction clutch is the most popular type. This system operates by the friction created between two shafts. The material lining the shafts impacts how much friction is created.

Multiple Plate Clutch

This type uses multiple plates to contact the engine flywheel and transfer power. Besides industrial machines, these are often used in racing vehicles because of the high torque they transmit. 

Cone Clutch

This type uses two conical surfaces to generate torque rather than disks or plates. Compared to other clutch types of the same size, it can transmit more torque. A disadvantage is that it needs significant maintenance.  

Centrifugal Clutch

This automatic type operates one centrifugal force with an output shaft. As a result, there isn’t much maintenance required, and the design is relatively simple. 

How To Tell If A Clutch Is Working Properly

Regardless of the clutch a machine uses, some issues require maintenance. Knowing what to look for can help you spot a problem before it gets more serious. The following clutch tips may help.


If the engine is revving at a high rate, but the machine is moving slowly, this could be a sign of slipping. This happens with a worn-out disk or plate. Another sign is hearing strange noises when you are shifting gears.

Pedal Give

If you have to press hard on the pedal or are sensitive to the touch, you are experiencing pedal give. This is a sign that a replacement is needed soon.


This is sticking if your foot moves from applying pressure to the pedal, but the clutch doesn’t follow. This can make changing gears difficult. 

Understanding Clutches and Their Importance

Now that you know how a clutch works and what to look for if malfunctioning, are you ready to learn more? Not all clutches are the same, as different types offer unique advantages.

Buying a Crane: How to Choose the Right One

Cranes have been used in one form or another to help construction sites for centuries. You understand that, but what do you need to consider when buying a crane or upgrading to a different crane?

Here is some crane buying advice to help you with your decision.

Buying a Crane for Your Specific Needs

Crane buying advice doesn’t start with thinking about the crane but your job sites. For example, what are the typical weather conditions? What type of terrain will you be working on?

When choosing a crane, you want to match the crane you upgrade to with your job’s load weights and dimensions. For example, multi-level jobs require longer booms, so your weight limit won’t decrease with higher lifts. 

Make sure to check the National Load Charts when looking at cranes. They will help you find the perfect fit based on the height and weight of your average job.

Remember that your rigging accessories weight will need to be deducted from the gross weight of the charts. This will help you find the actual load-bearing capacity of the crane for your jobs.

Crane Buying Guide

The type of work you do and the location will help you decide the type of crane you need. Here is a quick guide to some of the most common types of cranes.

Mobile Cranes

Mobile cranes can offer greater maneuverability and carry a lot of weight for their size. You want a rough terrain crane or a crawler crane for off-road construction.

Crawlers work great off-road because of their tracks and great counterweight control. In addition, they can handle loads in the 80-825 ton range. The carry deck crane is one of the most popular upgrades because of its ability to carry loads on site.

Carry deck cranes are hydraulic and can be operated by one person. Their load capacity is in the range of 7.5-15 tons. Most decks on the carry deck can transport between one to nine tons. 

Fixed Cranes

Fixed cranes are assembled on-site and used for long-term jobs and can handle more significant amounts of weight than mobile cranes.

Tower cranes have a jib extending from the mast, which rests on a concrete base. They can grow with a building while helping to build it. Hammerhead tower cranes have a swinging lever attached to a fixed tower.

They give you the ability to move loads horizontally. They are also modular, and their ability to adapt to your site makes them a versatile option for your construction needs.

Crane Buying Tips

When buying a crane, think through the type of work, the weight loads, and whether you need a mobile or fixed type of crane. This will guide you on the type and size of crane you get.

A Quick Guide to the Different Types of Cranes

Construction contributes about $1.4 trillion worth of new structures every year.

Different types of cranes play a part in construction work. Cranes use a combination of cables and pulleys to help lift and lower heavy materials. With construction showing no signs of slowing, it’s no surprise that estimates put the global crane market growing by a CAGR of 2.96% through 2027.

This crane guide will seek to help answer the question, “what are the different types of cranes?”

Static Cranes

A static crane has a fixed path. It remains fixed to the ground or building with the intent of lifting and moving materials along a set path.

Overhead Crane

An overhead crane looks and functions how it sounds. It has a horizontal beam fixed to a ceiling, often inside a warehouse. A trolley and hoist are attached to this beam and move along the beam to transport loads.

Tower Crane

When you see a skyscraper under construction, you often see a tower crane beside it. A tower crane is made up of a mast and a jib.

The jib can rotate 360 degrees, and a trolley and hook block travel along with this component.

Level-Luffing Crane

A level-luffing crane has a rotating jib that can slew and move in and out from the base. Attached to the jib is a vertical mast. A level-luffing crane is ideal for moving heavy loads that need to stay near ground level.

Mobile Cranes

A mobile crane is the opposite of a static crane. A mobile crane isn’t a semi-permanent or permanent structure. Instead, it comes mounted on either wheels or treads. This allows the mobile crane to move to new job sites when needed.

Crawler Crane

Sometimes called a lattice crane or telescopic crawler, the crawler crane is one of the largest cranes. They have heavy-duty treads and can lift and move materials that weigh more than 2500 tons.

Rough Terrain Crane

When there’s difficult off-roading work involved in conditions like mud or snow, the rough terrain crane is what you’ll find on-site. 

Also called an RT crane, they come mounted on four tires. A telescoping boom picks up and carries the load, weighing up to 165 tons. An RT crane is ideal for moving around in a confined area.

All-Terrain Crane

Think of the all-terrain crane as a mobile truck. This type of crane can travel on the highway since it is quite literally a crane mounted to a truck.

Mounted onto the bed of the truck is the telescopic boom. This is what lifts and moves the loads. An all-terrain crane is capable of lifting 1200 tons.

Truck Crane

The truck crane is a smaller, lighter version of the all-terrain crane. It consists of a boom affixed to the truck bed. They lift lighter loads than the all-terrain crane, only able to hit a load capacity of up to 45 tons.

Many Different Types of Cranes for Your Job

There are different types of cranes to choose from for a construction job. No matter how big or sturdy the crane, equipment wears down. Once that happens, Kor-Pak is here to help with replacement parts.

Kor-Pak is here to be your supplier for crane controls and materials handling needs. Whether you want to upgrade your crane or outfit it with the newest technology, we can help.

What Are the Benefits of Mobile Cranes?

Did you know that the demand for mobile cranes has increased by almost 30 percent in the last year? No other type of crane has seen this spike in demand. The main reason for this is that mobile cranes offer a wide variety of benefits to make your job easier.

Is a mobile crane the right option?

Let us look at some of the advantages they can offer.

Mobile Cranes Offer Flexibility

A mobile crane has excellent mobility and flexibility. If you need to use it in urban areas, where you will encounter obstructions, you have to know the crane can maneuver around them.

It can access narrow passages and can save space on a construction site. In addition, mobile cranes do not have a large footprint, so they are ideal for more crowded locations, like projects on city streets.

Unlike tower cranes, where you set them up and remain there for the project’s duration, that is not the case with a mobile crane. Instead, you can use it where you need to and move it to the following location without any trouble.

Quick Setup

Setting up a mobile crane is fast and straightforward. If you can get the crane up and running, you save time and money. For people using mobile crane rentals, this also means having to pay for fewer days since you do not have any delays.

A mobile crane is a single piece of equipment, and it is compact, making it likely that you can start operating it almost as soon as you get it to the site.

Saves Space

With its compact build, a mobile crane does not require a lot of space to function. They can fit through narrow passages and are shorter, making them better suited for passing under bridges. With a mobile crane, you can tackle the same project that a static crane could handle, but you save space.

Lifting Strength

Looking at a compacter crane, you may think it would provide weaker capabilities than a larger crane. That is not the case. A mobile crane uses heavy-duty axles, outriggers, and hydraulic power to lift the weight you need to the heights you require.

Many mobile cranes can lift more weight than a tower crane, and you have the benefit of being able to move it around the job site as needed.

Cost Efficiency

A mobile crane is a more affordable choice. It is easy to set running, with no added setup costs and wasted time. In addition, its speed and mobility allow you to get the most out of the crane if you are renting it since it minimizes downtime.

Keep Your Mobile Crane Running

With mobile cranes in high demand because of all of the benefits they bring to a job site, you want to keep yours running efficiently.

Drum Brake Parts: How Do They Work

Drum brakes are big business in the world of mass-production and heavy industry. The global market for this type of brake is set to surpass $3.5 billion in value by 2026. That’s good news for fans of these time-tested machinery components.

We all know drum brakes are still used in the automobile industry, but did you know they also have a far wider range of applications? Read on to understand the basics of drum brake parts and how you can put them to use in your manufacturing business.

Drum Brake Parts Basics

Unlike the more commonly-used disc brakes, which apply friction by clamping down on an object from the outside, drums use their stopping power from the inside. As a result, fluid fills a cylinder which pushes two shoes outwards.

It’s a relatively straightforward process, but there’s a little more going on below the surface.

The Drum

This is perhaps the most important part of drum brakes. The drum stands at the wheel’s center, bolted to the hub, rotating in time with the axle. The drum houses all other components of the brake.

Drums are usually made from a heat and water-resistant form of cast iron and provide a rugged shell for all the intricate components inside. The drum can stand up to a lot of wear and tear, with an average lifespan of around 150,000 to 200,000 miles. That’s a lot of rotations!

Backing Plate

Another critical brake element is the backing plate, which helps to shore up the drum. It provides a solid core at the back of the drum and helps to protect the rest of the braking system from damage.

Since it rubs up against the wheel and absorbs torque, this part is sometimes called the torque plate. 

Brake Shoe

The shoe is arguably the most critical part of the brake. It pushes out to the wheel, applying friction and eventually causing it to stop. 

It is made from two welded steel pieces operated by pistons pushing out from the drum. The shoe is lined with brake lining on its outer curve, providing the optimum level of friction.

Wheel Cylinder

The cylinder’s job is to push the shoe outwards. Operated by pistons at either side, it forces the shoes outwards, causing them to make friction with the edge of the drum.

Return Springs

Once the braking process is over, those shoes have to retract and take their pressure off the wheel. That’s where the return springs come in, pulling the shoes back to base when their job is done.

Self Adjuster

All braking systems rely on friction. So, it only follows that the whole system will break down if the shoe doesn’t make contact with the drum.

The self-adjuster allows the shoe to adjust as the lining deteriorates. The adjuster will push out further and ensure they make contact. The best drum brakes all offer this feature.

How Are Cranes Transported? A Quick Guide

Cranes are an integral part of construction projects lifting heavy materials vertically and horizontally. Without cranes, much of our modern infrastructure would not exist. 

If you have ever noticed tall cranes silhouetting a skyline, you may have wondered, “How are cranes transported?” Keep reading to find out more about crane transportation techniques and methods.

How Are Cranes Transported?

To answer “How are cranes transported?” you first must determine the type of crane needed for the job. Here are the two main categories of cranes that dictate transportation options.

Mobile Cranes

As the name suggests, mobile cranes can move around on their own. For example, rough terrain cranes have large wheels designed for moving over almost any surface. You can drive some of them on certain roads and highways.

However, like crawler cranes, some of these are made for moving around a construction site but not for driving on roads.

Truck-mounted cranes also are appropriate for road use. They usually have telescoping or folding booms. However, these cranes have limited applications due to their size and smaller load capacities.

Other cranes, like “pick and carry” cranes, are designed for moving around on the bed of a vehicle. These are very small machines and are not used in major building construction.

Fixed Cranes

All fixed cranes need some assembly on-site. Hanging cranes, for example, are permanent or semi-permanent machines that are built in coordination with the warehouse or building in which they operate. Similarly, engineers construct bridge cranes over some time by construction crews.

The most common way to transport taller cranes to the construction site is in pieces. Tower cranes, for instance, can reach several hundred feet in height. So they are disassembled into smaller pieces and transported by truck.

Once the pieces arrive at the construction site, reassembly can begin. This is often accomplished using smaller, mobile cranes. These cranes usually have a telescopic boom that reaches the necessary heights for putting the tower crane parts back together.

Self-erecting tower cranes are a newer technology and are driven to construction sites as a single unit. As a result, they often need special equipment for crane transportation. These cranes use a hydraulic system to unfold, taking as little as an hour.

Overhead Crane Remote Control: All You Need to Know

Did you know that cranes can operate from long distances? This is done by an overhead crane remote control and allows industrial machinery to be run remotely. Overhead cranes are an excellent choice if you’re looking to add efficiency and safety to your warehouse procedures.

The primary function of the crane remote is to increase the productivity and efficiency of your warehouse. By eliminating the need for workers to operate the crane while being inside it, you can streamline and improve your entire process.

To learn more about how a remote control crane can help your business, read on! 

What Is a Crane Remote Control?

A crane remote control is a remote-control system that consists of a portable transmitter unit. That transmitter unit is what generates the control signals which the crane receives.

There are several different types of cranes, including self-erecting, top-slewing, and flat-top. Each type has the potential to have remote control capabilities. This functionality is quickly becoming the standard for crane operation.

How Does It Work?


An overhead crane remote control handles the hydraulic winches and conveyor system in the overhead crane. This is what allows for the lifting and moving of heavy objects.

These controls can use radio frequencies to communicate with the crane and control its functions. You can use the remote controls in any location, but they must be within the distance required by the remote to function properly.

They can operate the boom of the crane, the main hoist, and the outriggers. It can also run with additional functions like jib angles, luffing, extending top jib, etc.

So how does it work exactly? The remote-control device works through communication between a transmitter and a receiver. 

When pressing any of the buttons on the transmitter, a signal travels to the receiver as radio waves. Those radio waves are perceived as data sent by the transmitter in an encrypted form. The purpose of this is to reduce any issue of potential external interruption within the system.

The transmitter works from as far as 200 meters away from the receiver. 

After the receiver gets the data, it decodes it and converts it into plain text. This is how the crane can mimic the functions inputted using the remote.


Using a remote control crane allows operators to start and stop the lift and even set up automatic cycles to operate independently. This will enable people that once had to operate the crane by hand to work in other capacities, increasing productivity.

This increased automation also helps prevent accidents from occurring in your workplace. For example, there is less room for error during operation with an overhead crane remote control system in place.

Bring Your Cranes to the Next Level

Overhead crane remote controls are essential for productivity. In addition, they offer the benefit of additional safety by allowing operators to control the crane from far distances.

Although this type of machinery increases productivity and safety, it also poses an additional concern for some aspects of safety due to its remote capabilities. When using a crane remote control, remaining observant and conducting necessary safety checks are always necessary.

An overhead crane system is a valuable asset to your company. It saves you the stress and time of lifting and transporting bulky loads.

What is an Overhead Crane System

An overhead crane is heavy-duty machinery. It is used to move bulky or heavy loads from one location to another.

The crane makes your manufacturing movements safe and precise. The crane system capitalizes on the overhead space of a manufacturing facility.

There are many types of cranes in terms of sizes, shapes, and configurations.

The diversity in configurations improves the capacity and performance of cranes when need be. Cranes’ primary function is loading and unloading, moving materials, lifting, and feeding raw materials.

How Does an Overhead Crane Work?

Moving bulky items in your facility, navigating aisles and floor spaces can be challenging. The overhead crane system has unique features to reduce the burden.

Power systems, electrical, mechanical, and controls facilitate its function. The electric hoist moves along the bridge to lift objects. Chain hoIsts are chain motors used to lift loads.

Cabins in cranes give visibility in the fieldwork.

Most cranes use an electric power supply, while others run on pneumatic power. The overhead controls give the operator complete control of the loads.

Start and Stop buttons command the crane’s movement. Advanced cranes feature joysticks and tablets to control a wide range of motion.

Crane parts differ depending on the type of crane. However, each overhead crane features a combination of configurations resourceful to its different functions.

You need an agile maintenance system for maximum functionality of your crane.

Benefits of Using Cranes

The value of overhead cranes is underestimated. Cranes facilitate the processing and handling of materials. The systems are relevant in assembly, transportation, staging, storage, or warehousing.

Cranes are adaptable and customizable to accommodate changing needs. For example, you may need the crane covering larger distances as your business grows. You can adjust the bridge and other features to match your emerging needs.

The machines have lower maintenance costs and labor expenses. However, employing staff to move bulky and heavy items can be costly.

You need long hours of labor and numerous staff to execute a single task. A crane will take a few minutes and a minimal power supply for the same job.

Overhead cranes automated system enables precise maneuvering through limited spaces.

Improve Your Operations with an Overhead Crane System

If your company requires the frequent movement of weighty load materials, it’s convenient to use overhead cranes.

Installing an overhead crane system makes work more efficient, cost-effective, and safer. In addition, overhead cranes can be engineered to fit your target applications.
