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. 

Quality Components Whatever Your Needs

Whatever you’re looking for in your business, you can rely on us as your provider. We’ve been in the industry for years and understand the importance of quality industrial equipment, including drum brake parts.

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.

Learn More About Crane Transportation

Now that you have an idea of how cranes are transported, you can determine the best method for your business. Crane manufacturers can also provide insight into crane transportation methods based on your particular construction demands.

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.

Is an Overhead Crane System Right for You? A Brief Guide

Did you know the market size of overhead cranes is expected to reach $5043.7 million by 2027? A 4.9% increase from 2020 to 2027 suggests increased use of cranes. Why do you think the demand for cranes continues to grow?

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.

Derrick vs. Crane: Is There a Difference?

Numerous types of cranes and similar devices have become integral parts of ports and shipyards throughout the years.

This includes the derrick. What is the real difference between a derrick and a crane? Is there one?

Learn more about this as we take a look at derrick vs. crane.

How They Are Similar

Before looking at how they differ, it helps to know their similarities. Both of them are hoisting machines that carry heavy loads, moving them around shipyards, construction sites, and factories.

The OSHA regulations for cranes apply to derricks since they are technically considered cranes. Both cranes and derricks have booms and use pulleys or sheaves to lift heavy objects.

Though many engineers use the words interchangeably because of their similarities, there are significant differences.

Identifying a Crane

The crane can move objects horizontally and vertically, offering efficient movement and a simple design.

There are two general categories of cranes: stationary and mobile. Stationary cranes cannot, as their name implies, move about, but they make up for this with the ability to carry heavier loads and adjust the length of the boom to move materials.

A stationary or fixed crane can be installed in one place. They are efficient, especially when transporting materials horizontally over a small distance. You can do this by adjusting the boom or rotating the crane.

A mobile crane is mounted on a track or wheels, allowing you to transport it from one location to another. They cannot handle loads that are as heavy as what a stationary crane can manage, but they allow you to place them where you need them.

You will find cranes in ports, factories, constructions sites, and more.

Identifying a Derrick

Like a crane, a derrick moves objects horizontally and vertically. They are made up of two or more simple machines that can lift large loads. These machines include pulleys or sheaves and hoisting mechanisms.

Unlike a crane, a derrick has a stationary mast and rises from the base. It also has a moveable boom. 

The boom has cables and sheaves (or pulleys), which guy wires stabilize and which you have to manipulate if you want to move an object from side to side. There are different setups for the mast, and you may even come across derricks with more than one mast and boom.

A derrick has its weight evenly distributed, allowing it to lift heavier loads than most cranes.

Places where you might see derricks are ports, oil rigs, and cargo ships.

Derrick vs. Crane: Which One Is the Right One?

The answer will depend on the job, where it will take place, how much mobility you need, and how heavy the loads are.

A crane is the best option for a job that requires moving from site to site. However, a derrick is a more efficient option for a stationary job because of its simple construction and evenly-distributed weight.

Maximize Your Machines

Whichever machine you prefer — derrick vs. crane, you want it to work efficiently as you tackle your next job.

Essential Things to Know About an Electrical Crane

With the many types of electric cranes available in the market today, getting the best among them is easier said than done. To guide you on getting the best kind of crane, understand that there are two main types of cranes; mobile and fixed cranes.

As their name suggests, fixed cranes are cranes mounted on one specific location. Since they are immobile, fixed cranes are set at one particular place for the duration of a project.

Fixed cranes are likely to lift heavier goods to higher heights than electric cranes.

Examples of fixed cranes are jib cranes, gantry, and overhead cranes.

On the other hand, mobile cranes are portable since they are mounted on tires, crawlers, or trucks.

These cranes are the most popular in industries since moving them around for different tasks is possible.

Common mobile cranes are crawler cranes, rough terrain cranes, carry deck cranes and truck-mounted cranes.

How Do You Maintain an Electrical Crane?

Regardless of your type of crane, one thing is for sure; it is a considerable investment. For this reason, you should strive to preserve the condition of the crane to make it long-lasting and efficient.

How do you ensure that your electric crane is well maintained?

Lubricate It

Lubrication is critical for the proper functioning of any machine parts. Therefore, find the right amount of lubrication needed for your crane and how often you need it, and lubricate it to prevent wear and tear.

Remember to replace gear oil after the crane has worked for the specified number of hours. Always use quality oil and lubrication for proper maintenance of your crane.

Avoid Rusting

Although most cranes are resistant to rusting and corrosion, elements such as weather may result in rusting. This can damage sensitive crane parts, thus affecting its performance.

Therefore, ensure that you implement maintenance skills that prevent rusting of any parts.

Frequent Examination

Minor problems with the electric crane could result in fatal repercussions. For this reason, frequently examine the machine and get crane repair services where necessary.

If the crane is used frequently, have a routine examination by a professional at least three times per year. On the other hand, if it is not frequently used, you can check it once or twice a year.

Are You in Need of an Electrical Crane?

Electrical cranes are heroes in many industries. It is an investment that will help boost efficiency and safety in your industry.

How Does a Hydraulic Crane Work? A Brief Guide

The Ancient Greeks invented cranes in the 6th century or earlier. Since then, we have relied on cranes to build our most significant structures.

And the hydraulic crane is the most efficient of all. You can apply constant torque at any speed. And they are simple to control and maintain.

Let’s take a look at how hydraulic cranes work.

The Basics of Hydraulics

Hydraulic systems change mechanical energy into hydraulic energy, then back to mechanical again. They use pistons, cylinders, and pressure to do this.

Oil is the most common hydraulic fluid. It is hard to compress, which makes it ideal for this purpose. Its viscosity is vital, as is its availability and cost.

The first piston pushes this fluid down. This displacement puts pressure on a piston at the other end of the cylinder. The second piston then moves up or out. This movement drives the crane’s lifting system.

Hydraulics avoid the heat generated by mechanical means. They bypass the friction of metal-on-metal systems giving them an advantage.

They are quieter and easier to maintain. They can generate more lifting power with less wasted energy than mechanical systems. 

Parts of a Hydraulic Crane System

Both hydraulic truck cranes and fixed cranes use a boom and jib to lift loads. The boom can extend on most models. The jib attaches to the end of the boom,  increasing reach.

A counterweight sits at the opposite end to the jib. This balances the upper parts of the crane while it lifts loads.

Most hydraulic truck cranes have outriggers. These beams extend out to the ground stabilizing the crane.

Then there is the hydraulic lifting system and its pump.

Types of Hydraulic Crane Pumps

There are two main types of hydraulic pumps: gear pumps and variable-displacement pumps.

The gear pump is the most common. But the precision of variable-displacement pumps suits some projects. So let’s take a look at how both work.

Gear Pumps

Most cranes use gear pumps to displace hydraulic fluid between pistons. These are the more affordable options, and their simplicity can make repairing cranes easier. 

Two interlocking gears move a piston to put pressure on hydraulic fluid. This pressure moves the opposite piston.

They are simple to operate. More engine power equals more hydraulic pressure and greater lifting capacity.

Variable-Displacement Pumps

Variable-displacement pumps have piston cylinders joined to a ring within a barrel. This barrel spins, rotating the cylinders. A swashplate drives the first pistons in and out.

This motion displaces fluid in the cylinders. This pressure moves the opposite pistons out, driving the lifting mechanism.

The crane operator can change the fluid flow rate and outlet pressure giving them more precision when lifting. 

This control comes at a cost. Variable-displacement pumps are more expensive and harder to repair than gear pumps. 

Need Hydraulic Crane Parts or Repairs? 

Hydraulic cranes are invaluable tools for efficient lifting. Maintenance helps keep them that way.

But components wear with use. So to keep your hydraulic crane at its best, you might need new parts from time to time.

At Kor-Pak, we stock a huge selection of parts for various cranes. And if you need a professional to fit them, we can service your crane for you.

Parts of Port Cranes You Should Know About: A Closer Look

Did you know that one of the most common issues port cranes deal with is chain link problems? The links can start cracking from overuse or even improper use.

If you want to have ship-to-shore cranes that work efficiently, you need to know how each of their parts works. That will let you know when they are not working correctly.

Read on for a look at the essential parts of port cranes.

Main Boom

This is the part of the port crane that hangs over the ship. The main boom has a hinge above the quay to be lifted, giving space for the ship to move as it needs to. If the crane is smaller and used near airports, where visibility is critical, low-profile booms work best because you can pull them toward the crane when not in use.

Supporting Frame of Port Cranes

This is the structure that holds the boom and the spreader. It is significant, and when on the jetty and performing transverse movements, the frame can be on rubber wheels or rail mounted.

The boogie wheelsets are under the crane’s legs, and you can expect the crane to have eight wheels per corner.


The spreader is attached to the rail structure and the operator’s cabin. It can also move transversely on the boom when lifting cargo, and it is connected to the trolley with cables.

This is the part of the crane that lifts the containers. Depending on the number of containers, it can open and close as needed. Some of them can lift up to four containers at the same time.


This is the part that supports the spreader and the operator’s cabin. Finally, a trolley supports the mechanism that lets it ride over the boom while also supporting the hoisting mechanism.


The crane’s legs generate its height. The more modern cranes have higher legs since the stacking of containers has risen. So you can expect up to eleven containers stacked one on top of the other above decks; the crane has to accommodate that height.

The waterside leg, or WS, is thicker than the landside leg, or LS. This is because the WS has to withstand more moment forces.

Power Supply and Cable Reel

A port crane usually has two kinds of power supplies: the diesel generator powered by an engine and rests at the top of the crane and the electric power from the dock and the terminal facilities.

Cables create the electrical connection, and they lay in large gutters over the quay. When the crane moves, the motorized reel rolls them on or off.

Keep Your Equipment Working

By knowing the parts of port cranes and how they function concerning the rest, you will know when something is off. If you see parts that need repairs, turn to the experts for help.
