4 Benefits of a Custom-Built Crane Transmission

Two of the most common reasons for crane-related workplace accidents are boom or cable failure and the worker getting struck by the crane load. Such accidents are often catastrophic. 

A custom crane transmission can help you prevent such accidents from happening. It can also benefit your company in other ways. Read on to learn more. 

1. Tailor the Crane to Your Specific Needs 

Most crane transmission brands only offer a few options for complete, pre-built transmissions. As a result, businesses may find that the resulting products only meet some of their operational needs. The best they can do is weigh the pros and cons and choose which parts meet as many of their needs as possible. 

The problem is that this can lower production rates because the workers have to work within the limits of the crane. If they try to push these limits to meet production demands (adding too much weight, etc.), their safety will be at risk. Also, a misused crane will likely break more often and need more maintenance. 

Custom cranes are the best way to ensure your crane meets production demands and is safe. This way, your crane will be able to meet more of your business’s needs. 

2. Replace an Outdated Crane Transmission 

In most cases, replacing parts of an old crane is much cheaper than buying a new one. However, you may need help finding parts that fit your old crane. 

You’re not guaranteed to find the right parts to upgrade your old crane. Still, you have a better chance of doing so by building a crane transmission piece rather than buying a complete set of parts at once. 

3. Take Advantage of Radio-Control Technologies 

Newer crane systems have technologies that can improve your production in several ways. Getting a new custom-built transmission and other parts can help you take advantage of these features.

One example of these technologies includes radio remote control systems. They can enhance your crane’s performance by improving safety and providing versatile action options. 

4. Take Advantage of Life-Extending Mechanics 

Another way new crane systems can improve your production is by extending your machines’ lifespans. Recent innovations in technology can improve how long and well your crane operates.

The Importance of Regular Crane Inspections

You rely on your cranes daily to get your jobs done and generate revenue. Research shows that unplanned equipment downtime costs an average of $260,000 an hour.

Inspecting your crane can help you spot problems early on. Here’s a rundown of why regular care inspections are so necessary.

Longer Equipment Life

A regular crane inspection can save you on crane-related costs in the long run. That’s because regular maintenance can help ensure that your crane remains pristine in the years ahead.

When you have your crane inspected and serviced as needed, this equipment will be more reliable when you need it the most. It will also last longer.

A fully operational crane will help you avoid the costly downtime that stems from parts failing and equipment breakdowns. After all, it takes longer to fix a broken crane than to get it inspected yearly.

And when you catch problems early in an inspection, you prevent more significant problems from cropping up later.

Employee Safety

Yet another reason to inspect your cranes regularly is that it helps keep your staff safe.

With a consistently inspected crane, the users of your crane are less likely to suffer job injuries due to malfunctioning equipment. Likewise, you prevent employees working around your cranes from being injured due to equipment failure.

The safer your employees are, the happier they will be, and the more likely they will stay with your company. In addition, fewer work-related injuries translate to lower costs for you.

OSHA Compliance

Finally, conducting regular crane inspections is a requirement of the Occupational Safety and Health Administration, or OSHA, for various industries, including agriculture and petroleum.

If you neglect crane inspections, you will not comply with OSHA. Unfortunately, this may lead to a higher number of workplace accidents. In addition, it may lead to hefty fines that further chip away at your bottom line.

When OSHA fines you, this can also damage your reputation among your business partners and clients. And if you continue to operate without compliance with OSHA, they may eventually shut down your business.

A yearly inspection is an easy way to keep your cranes operating according to code and stay in business.

How We Can Help with Crane Inspections

With regular crane inspections, you can extend the life of your heavy equipment. In addition, you can have the peace of mind of knowing that your workers will be safer. And you can avoid OSHA fines as a result.

5 Things You Should Know About Industrial Brakes

Regular brakes and industrial brakes differ from one another. Here are a few things to know about industrial brakes and their maintenance.

1. There Are Different Types of Brakes

It is essential to have industrial brakes to manage heavy loads. Here are a few examples.

Spring Applied Brakes

Spring-applied brakes are meant to decelerate moving loads and keep other heavy loads still in case the release mechanism stops working. 

These brakes are especially useful for industrial machines and any type of industrial machine that needs an emergency stop.

Fail Safe Brakes

If there is an issue with power loss or something with the drive that goes out, the fail-safe brakes will help. This is especially useful for downhill systems or even conveyor belt systems. 

Hydraulic Release Brakes

This is another type of spring-applied brake that uses hydraulic power. This is useful for holding, stage productions, and emergency stops for industrial vehicles. 

2. How They Work

Even though there are several different types of industrial brakes on the market, most use signed disc designs that use a rotating disc. This disc completes movement that creates friction to stop a vehicle.

These brakes are highly reliable in high-stress situations and can last many hours. First, however, it is vital to ensure they are adequately maintained. 

3. Always Look to Improve Braking Performance

It is essential to pay attention to brake performance when you have industrial brakes. Here are some things to look out for:

  • Increase the disc radius to ensure there is more brake torque and the ability for the brakes to apply the proper pressure
  • Increase the caliper piston area or the size of the pistons to increase pressure on the brakes
  • Increase the line pressure with assisted vacuum parts on the brake or by pushing harder on the brakes
  • Increase the friction between the brake pads and rotors on all wheels 

4. Reduce Brake Fade

You should also reduce brake fade to keep your industrial brakes safe. A few ways to do this are:

  • Adding larger rotors to the vehicle
  • Add vented rotors or a way of venting for your rotors
  • Add slotted and drilled rotors
  • Be sure to look at your brake pad selection properly 

5. Always Choose the Right Company to Help You

To be sure that you are choosing the right company, you want to ensure you are looking for the following. This should always be a part of what you look for in an industrial brake company:

  • Customer service
  • High-quality components
  • Industry experience 

Industrial Braking

Now that you know what to look for with industrial brakes, you can start your search by knowing how to choose the right ones.

What Is Fluid Coupling and How Does It Work?

The principles of fluid dynamics are present in nearly all modern inventions. From modern toilets to rocket propulsion, it’s hard to find any revolutionary technology that doesn’t use it. Fluid dynamics is one of the most important products in engineering.

Like most engineering concepts, the fluid coupling can be a bit of a puzzle. Luckily, we’re here to make things simple. Read on for a simple and intuitive way to understand fluid coupling.

What Is Fluid Coupling?

Fluid coupling, also called hydraulic coupling, is a hydrodynamic device that uses transmission fluid to transfer mechanical power. 

German scientist Dr. Hermann Fottinger invented fluid couplings. His invention was patented posthumously in 1950 and has been used for various industrial applications since then. 

How Does It Work?

The principles of fluid coupling are based on hydrokinetics and fluid dynamics. This makes it distinctly different from hydrostatic systems like hydraulic pumps. 

A fluid coupling consists of a pair of bladed wheels that face each other but make no physical contact. One wheel, called the impeller, gets connected to a power source. The other, called the turbine, receives power from the impeller that transfers directly to the transmission.

The impeller, also known as the input, spins faster than the turbine, which is the output. Fluid flowing from the input causes the output to spin and transfers energy throughout the system. Both wheels are housed in an oil-filled casing that keeps them in place.

Fluid Coupling Applications

Fluid couplings get used in several different industries. However, its most important contribution is to the automotive industry. Let’s take a look at how.

Automatic Transmissions

Before the invention of fluid coupling, all cars had a manual transmission. Manual transmission requires the driver to operate a clutch, which is the link between the engine and the transmission. Without its clutch, a manual transmission car would stall whenever it stops.

The invention of fluid coupling removed the need for a clutch. It became the source of torque conversion needed to make cars shift gears automatically. Every automatic car on the road today has been partly built using fluid coupling.

Semi-Automatic Transmissions

The use of fluid coupling extends beyond just motor vehicles. Fluid couplings also have an important benefit in rail transportation.

In Britain, diesel locomotives have a power transmission system that is semi-automatic. This power transmission employs fluid couplings to make the locomotives shift gears automatically while in motion.

Additional Resources

Despite being less than 100 years old, fluid couplings have revolutionized how automobiles and locomotives run. The automotive industry relies on its principles and wouldn’t be the same without them.

The Advantages of Vertical Wind Turbines Over Horizontal Ones

A windmill-shaped wind turbine, aka a horizontal wind turbine, is no longer the only model available for wind farms. A vertical wind turbine is now a viable electrical energy generation machine as well.

The main difference between these two models is the blades’ movement and shape differences. The blades of traditional turbines spin perpendicularly to the ground. In the meantime, the blades of vertical turbines spin parallel to the ground

Many experts also believe vertical turbines can surpass horizontal ones in many areas. 

A Vertical Wind Turbine Is Shorter and Smaller

A vertical-axis wind turbine (VAWT) is much shorter than its horizontal counterpart. Several advantages come with this size reduction. 

One of these is that the VAWTs don’t block any scenery. A wind farm made of traditional turbines can easily obscure a nice mountain view. Vertical wind turbine wind farms are short enough not to obstruct this scenery. 

Another is that the vertical models can easily fit in urban areas. For example, they can be placed on the tops of buildings. This isn’t the case for the massive horizontal models. 

Vertical Wind Turbine Wind Farms Can Be Smaller in Area

A wind farm full of horizontal turbines must be huge to be most efficient. This is because a horizontal wind turbine creates a wake that affects the efficiency of other turbines in the group. Thus, the turbines in traditional wind farms have to be spaced far apart.

Vertical turbines don’t lose much electrical energy generation efficiency when they are placed close together. This is because vertical turbines create winds that are less turbulent in general. Thus, vertical turbine wind farms can be much smaller. 

Different Vertical Wind Turbine Models Have Different Advantages

Not all vertical wind turbine models have the same advantages, though. For example, the Savonius rotor model, which has blades shaped like cups/bowls or semi-cylinders, is less efficient at energy generation than other models. However, it is excellent for pumping water. 

In contrast, the Darrieus model spins much faster, and looks almost like an egg beater, spins much quicker. Thus, it would be much preferable to use it for energy generation.

The Future of the Steel Industry: What Does It Hold?

The United States produced 1,742,000 net tons of raw steel this week alone. About half of this steel will be used in construction as it is robust and cost-effective. Steel has long been a staple of the United States economy and will continue to do so by the looks of it.

Despite the pandemic and supply chain disruptions, the steel industry is as strong as ever. In a fast-changing world, steel is adapting and evolving just as fast. Continue reading below to learn more about the future of the steel industry.

Zero Slag Process

The steel industry is committed to keeping pace with environmentally-safe practices. One way they can do this is by reducing or eliminating slag from steel production.

Slag is a waste product produced from dephosphorization, the removal of phosphorous from steel. While some steel slag can be recycled,  most of it is disposed of in a landfill.

Some countries, including Japan, have been working towards a zero-slag production process in recent years. This involves limiting the amount of silicon and allowing lime to react with the phosphorus oxides. In this way, dephosphorization can be initiated without producing slag.

ero-slag, zero-waste steel production is more sustainable and will bring steel production to the next level.

Innovations in Recycling

Steel is already highly recyclable, being the most recycled material on earth. Recycling just one car’s worth of steel can offset the greenhouse gas equivalent of 300 gallons of gas.

Even so, there is room for improvement. For example, the steel industry can improve the recycling process by reducing copper concentrations in steel.

Stronger Steel

With the same materials but different heating and alloying processes, researchers can make more robust steel, but sometimes at the expense of flexibility.

However, through a new process called grain-boundary delamination, it is possible to make stronger steel than traditional steel while maintaining its flexibility. Because this more robust steel uses many of the same materials, it costs the same. 

Steel in Space

Steel is headed to space. For decades steel has been the go-to choice for building rockets and is a standard metal in the International Space Station. Because steel performs better at high temperatures than carbon fiber, it is perfect for rocket construction.

Steel in Cars

Steel will continue to dominate the car-manufacturing business. Although other metals, like carbon fiber, may be lighter, they are also more expensive and harder to repair and replace. 

The Future Is Bright for the Steel Industry

Steel is a renewable resource worthy of space travel. The steel industry is strengthening, creating more flexible, recyclable, sustainable, and reliable steel. For more information, contact us today.


How to Choose the Right Industrial Material for Your Project

The United States produces around 7.6 billion tons of industrial waste every year. Some of the waste results from choosing the wrong industrial materials for the project. So, what factors should go into selecting a suitable material?

Below, we list the four factors you should consider when choosing manufacturing materials. By the end, you should have a much better idea of how to pick the best tool for the job. This way, you will avoid adding to the waste.


Consider the physical environment that the finalized project must endure. Are there factors you need to consider that might hamper how well the materials stand up to stresses?

The following are a few examples of the kinds of things that you might need to be aware of:

  • Corrosive liquids
  • Dust or detritus buildup
  • Gases and vapors
  • Inclement weather
  • Temperature extremes

Any of the above might cause wear and tear to the product and need specific material choices to counteract their effects. Some materials will stand up to certain stresses, and some will not react with specific corrosive liquids.


When debating the materials for manufacturing, you need to consider how much physical pressure the object will incur. This might happen from someone using it, but it is still as valid to consider how people will store it.

If the construction material needs to carry a load, it needs to be made of hardier materials that are not brittle. Should it need specific breakage points, these should break in a way conducive to what the item needs to do.

You must also ensure that any customizations you make to the material will hold. For example, If you plan to create latticework, it should remain strong enough even when formed into such a structure.

Cost and Budget

One of the most important things that will factor into whether you use a specific material or not is how much it costs. Before pulling the trigger on any particular material, you should consider your budget and what you can afford before pulling the trigger on any specific material.

It may be that hardier materials cost more. As such, you or your company should discuss whether you are willing to accept a less superior material due to budgetary constraints.

With the above information available to you, likely, you can now choose the best industrial materials for a job. First, consult us if you are still trying to find the best way to solve an industrial issue.

We have experts ready to discuss your material requirements and what you need to get a job done. So send us a message to get the best advice on the market.


How to Maintain Your Wind Turbine for Longevity

The average lifespan of a wind turbine is around 20 years. However, some wind turbines can last up to 25 years. Others can have lifespans as short as ten years. 

The quality of different wind turbine brands and models is a sizable part of this lifespan difference. Yet, specific actions you take can extend your turbine’s lifespan. Performing proper wind turbine maintenance is one such action. 

How Often Should a Wind Turbine Get Inspected? 

There are two kinds of manual turbine inspection: regular and thorough. Regular inspection should involve visual inspections and perhaps function tests. Both of these actions usually involve only the most crucial turbine components. 

A thorough inspection is more involved. During these inspections, the technicians should examine all components. In addition, a disassembly of specific internal components often takes place during this time. 

Regular inspections should take place first around 360 hours after the initial installation. After that, they should happen semi-annually. More specifically, they should take place every 6 to 7 months. 

A thorough inspection can take place every five years. However, it’s probably best for them to happen with more regularity. 

Remember, though, that proper maintenance schedules vary between turbine types. Windmill-shaped horizontal turbines, for example, require more maintenance. On the other hand, vertical turbines, which look like egg beaters, mostly require less maintenance. 

Which Actions Should Happen During Wind Turbine Maintenance? 

There are also a few actions that technicians can take during their turbine inspection appointments. These include turbine cleaning, lubrication, and other tasks. Beyond that, technicians can tackle issues as they notice them. 

Certain turbine areas need regular cleaning. For example, techs often need to remove debris, like vegetation, from the rotor. They should also remove dust from the nacelles. 

In addition, they should change the oil regularly. The bearings and gearbox also need lubrication to prevent too much wear. 

Beyond that, maintenance mainly involves damage control. If a part, such as the brakes, is damaged, the techs can attempt to fix it. If they can’t, they’ll replace the part. 

What Are the Different Maintenance Strategies? 

There are two types of maintenance strategies for wind turbines—one is predictive maintenance, and the other is preventative maintenance. 

Preventative maintenance involves the steps described above. In addition, technicians inspect and maintain the components of a turbine regularly. 

Predictive maintenance is less hands-on. Instead, it involves a software program connected to the turbine components. This software analyzes the components and predicts when will need maintenance. 

Contact Us to Get High-Quality Wind Turbine Brakes 

In a nutshell, high-quality wind turbine maintenance requires only organization. Maintenance appointments need to be scheduled and performed. A predictive software needs to be installed. 

Unfortunately, despite your efforts, turbine parts can fail. When that happens, check our inventory. We offer a multitude of high-quality aftermarket turbine parts.

The Different Types of Industrial Braking Systems

Braking systems are a critical part of industrial machinery. Through friction, they stop or slow the movement of mechanisms. Without them, machines would just keep moving even through dangerous situations.

It’s crucial, therefore, that each of your machines has an effective braking system. The best way to ensure this is to give each device the proper braking system. To do this, you’ll need to know the differences between different braking systems. 

Read on to learn more about some of the different industrial braking systems. 

Braking System Types According to Actuation

Actuation refers to how a system is activated or deactivated. For example, a brake system refers to the specific mechanisms that help a brake stop or slow mechanical movement.

There are a few different actuation constructions. This article will detail these further in the list below. 

Mechanical Braking System 

Mechanical brakes utilize manual power to operate. Therefore, an operator cannot use an automatic mechanism to actuate the brakes. Instead, they have to use their own hands or feet for this. 

The force resulting from this isn’t powerful. However, this braking system type is still useful in applications requiring little force. An excellent example of this is the handbrake on a bicycle.  

Hydraulic Braking System 

The actuation of a hydraulic braking system relies on hydraulic fluid. This is usually a mixture of glycerine, alcohol, and additives. The mechanism will transmit pressure through this liquid.

This braking system type is one of the cheapest, most common, and most reliable. Also, passenger vehicle brakes often rely on hydraulic systems. 

Electric Braking System 

Electric braking systems use magnetic force to actuate brakes. However, the magnets within the system are not always drawn to each other. Therefore, an operator must run an electric current through them to activate a magnetic force. 

These systems tend to be expensive but very effective. They also engage quickly. 

The Parts of Braking Systems 

Within the different actuation mechanisms are certain brake types. As a result, various systems may or may not share the same brake models.

The drum brake and disc brake are two of the most well-known. You can learn more about each of these below. 

Disc Brake 

A disc brake is named for the disc-shaped part that is often connected to a wheel. Above the disc is a C-shaped part known as a caliper whose sides extend over the disc.

When an operator applies the brake, a piston on one side of the caliper moves forward. This eventually squeezes the disc against the other side of the caliper. As a result, the disc stops spinning. 

Drum Brake 

All of the mechanisms of a drum brake are inside a cylinder-like house. Like the disc brake, a drum brake also has a piston. However, when activated, this piston pushes C-shaped ‘brake shoes’ against the inner sides of the drum.

Different Types of Crane Parts and Their Uses

The crane is a powerful piece of machinery for hoisting and moving materials. It can lift vertically and horizontally, making it useful in various scenarios.

Yet, for the crane to work effectively and safely, it’s essential to understand how a crane is set. This is because the crane parts work together not only to lift and move materials but also to keep the crane securely on the ground, too. 

Read on to learn a little more about the different crane parts and their role in the safe operation of a crane

Crane Mast

The crane mast is the part of the crane that acts like a tower lifting the other components into the air, so they have room to work. Therefore, this part is sometimes called a tower. 

The wire to handle the hook and pulley system used by the crane runs up through the tower. 

Climbing Frame

The climbing frame is a section built over the crane mast. It contains many of the components that allow the crane to operate. 

The climbing frame also allows the crane operator to get to the operator’s cab. 

Slewing Unit

The slewing unit is an integral part of the crane for movement. Most people understand that a crane can lift items vertically up and down. 

A crane can also lift and move objects from side to side. It can do this because of the slewing unit.

This part of the crane works to twist the crane, allowing it to turn 360 degrees around. 

Operator’s Cab

The operator’s cab houses all of the controls to operate the crane. The crane operator must go up to the operator’s cab, often high up, sitting on the hoist. 

A crane operator needs to have maximum visibility as they operate the crane. For this reason, the operator’s cab is often quite elevated on the machine. 

Machinery Arm and Jib

You can find the machinery arm on a traditional crane that holds a crane mast. The machinery arm keeps the materials away from the crane for safe movement. 

On a crane with a boom, you’ll often see a jib, similar in function to the machinery arm. The jib is a separate telescoping arm that projects from the crane’s boom, allowing it further reach so the crane doesn’t need to get moved. 

Concrete Counterweight

A crane couldn’t operate without the counterweight. It’s the part of the crane that counteracts the weight being lifted. 

When operating a crane, it’s critical to know the weight you’re lifting, so the appropriate amount of counterweight can be in place. 

This keeps the crane from tipping while it swings and moves heavy loads. 


The crane also couldn’t operate without a hook or a device like it. The hook gets used to connect the material being lifted with the crane. 

The hook holds onto the lifted material so the crane can move it. 

Know Crane Parts Before Operation

The crane is an essential part of a worksite and warehouse because it can do the heavy lifting to places you might not be able to get other equipment to. Understanding how the crane parts work together will allow you to use the crane effectively.
