What Are the Different Types of Port Cranes?

The Port of Los Angeles handles around 200 million metric tons of cargo annually. More than 80 port cranes operate nearly continuously to offload freight from container ships. 

The port crane is the central and most important piece of equipment at any port of entry. But have you ever wondered what the different types of port cranes are? Read on to learn about shore cranes and other types of port cranes.

Gantry Crane

A gantry crane is a type of industrial crane frequently found along ports of entry. This crane is named for its most distinguishable part: the gantry. This is the overhead structure that holds the crane.

The gantry crane is sometimes called a portal crane because the frame looks like a portal. These cranes work in what is known as the straight-line route. This means machinery is used directly underneath the crane itself.  

There are two types of gantry cranes: high and low profile. They function the same way, although they appear different.

The low-profile crane typically has a fixed boom. The design is ideal for situations where the seaport is also near an airport. The lower profile makes flying overhead safer. 

A high-profile crane has a hinged boom that is also tall. This configuration is ideal for helping ships navigate ports when leaving the dock. 

Deck Crane

Deck cranes are offshore cranes that are typically mounted on the decks of ships. Their compact structure allows them to take up very little space when raising, loading, or unloading cargo. 

With little or no nearby infrastructure, deck cranes can easily work in small ports.

Overhead Cranes

An overhead crane is often used in factories for lifting heavy loads. It is also known as a suspended crane.

In addition to lifting enormous amounts of weight, overhead cranes are simple in design, consisting of hoists placed on trolleys that can traverse one or two beams. The crane operator is responsible for controlling this powerful machine. Construction sites and ports both use overhead cranes. 

Learn More Useful Port Crane Tips

The port crane is the central equipment for any port of entry. Without port cranes, freight could never leave the ships, and ports could not function. Due to the unique needs of ports worldwide, port operators rely on a wide range of port cranes to complete their essential logistical work.

Keeping crane operators fitted with the necessary equipment is part of our mission at Kor-Pak. To learn about our diverse portfolio of products, contact our team today.

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. 

Keep Your Heavy Industry Machines Efficient With Our Part Selections 

You’re not limited to an inefficient or unsuitable crane transmission. There are plenty of ways to get the exact parts your business needs. In addition, this should increase the production level of your facility.

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.

Fortunately, at Kor-Pak Corporation, we take pride in offering parts and services for cranes and other industrial equipment, like clutches and brakes. Get in touch with us to learn more about how we can keep your cranes running smoothly from one job to the next and for years to come.

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

7 Things You Should Know About Crane Wheel Replacements

Easily one of the most recognizable pieces of construction equipment is the crane. However, maintaining these complex machines takes careful attention and an eye toward crane wheel replacement. Keep these seven important topics in mind to keep your construction cranes in optimal shape.

1. Worn Crane Wheels Are a Safety Issue

OSHA sets guidelines for construction companies. These include requirements that all equipment be inspected and well-maintained. If your company is working on lowering its liability, ensure you designate timely construction crane wheel replacements as a top priority. 

2. Worn Crane Wheels Can Delay Construction Timelines

A blown or misaligned crane wheel can bring construction projects to a grinding halt. Since construction cranes are a vital part of any project, these delays could mean a timeline setback of days, if not weeks. 

3. Busted or Damaged Wheels Could Cause Failed Safety Inspections

Whether caused by a malfunctioning industrial brake system or general wear and tear, a damaged crane tire can cause your company to fail a safety inspection. A failed inspection could mean both fines and delays. 

4. Tire Problems Can Cause Distinct Sounds

We are all familiar with the sounds of worn brake pads. Misaligned or badly worn crane tires also make distinct sounds. Pay attention to those telltale sounds. An early diagnosis of the problem could mean a cheap and quick fix. 

5. Crane Wheels Are Not Interchangeable

When it does come time to replace your crane wheels, you should remember to pay close attention to the manufacturer’s specs. That will ensure that the wheels you purchase can withstand the conditions and loads they will experience daily. 

6. Prevent Premature Wear

Crane wheels wear out faster on older rail systems. A misaligned runway can also cause premature wear. You can prevent premature wear by ensuring your crane is regularly tested and inspected. 

You should address early signs of wear before the problems compound. Finally, ensure wheels were made for the specific rail they run on.

7. Routine Inspections Can Prevent Premature Tire Wear

Don’t wait for outside inspectors to tell you that your crane wheel requires replacement. Instead, make maintaining and inspecting your equipment a weekly routine. Better yet, have a daily checklist for essential things like checking the condition of your tires.

Learn More Tips About Crane Wheel Replacement

Crane wheel replacement is an unavoidable expense, but following the tips in this article can prevent premature wear. When it does come time to replace your crane’s tires, work with reputable Kor-Pak products.

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.
