How Do Electric Brakes Work in Industrial Vehicles

If you were not aware, industrial vehicles use a different type of braking system known as electric brakes. They are typically standard in cranes and trailers. An electronic brake is similar to hydraulic brakes in cars. 

Keep reading to learn more about how electric brakes work in industrial vehicles.

Brake Controller

Every electric brake has and needs a brake controller. The controller is what modulates the electrical current that is sent to the electric trailer brake anytime the brake pedal is pressed. 

The controller is connected to the stoplight switch and the vehicle battery. When you depress the brake pedal, the controller is energized.

You have two options when it comes to a brake controller:

Proportional Controllers

This type of controller is also known as an inertia controller. Proportional controllers have a mechanism that determines how quickly the tow vehicle is stopping, and it modulates the power to the brakes in proportion to how fast the vehicle is stopping. The brakes are applied at the same rate and at the same time as the tow vehicle brakes. 

Time Delay Controller

This controller option is not automatic, like proportional controllers. The controls have to be adjusted to compensate for the weight of the vehicle the moment the brakes are pressed.

If a time delay controller is not adjusted correctly it can lead to too much stopping assistance or too little. Either way, it can cause an accident or hurt the driver.

The Mechanics Explained

Now that you know that there is always a controller present with electric brakes, let’s go over how exactly they work. There is an electromagnet in the backing plate that has two conductor wires that tap directly into the trailer wiring. 

When the electricity is on, the brake magnet magnetizes, and it is attracted to the drum face. Once it makes contact, the friction makes it rotate, which causes the actuating arm to move, which then pushes the shoes out against the drum. Once those shoes come in contact with the inside of the drum and press on them, it prevents the hub and wheel from spinning.

How Does Electricity Reach the Brakes?

There is an electrical connection on the industrial vehicle (crane, trailer, etc) that plugs into the connector on the vehicle. There are electrical wires that run from the trailer connector to each brake on the axle and the trailer lights to complete the circuit.

As soon as the driver hits the brakes, a current of electricity goes from the brake control to the vehicle. Then the brake control sends a current back to the vehicle and activates the electrical brakes.

Feeling Like an Electric Brake Pro?

Now that you are aware of how an electric brake works in industrial vehicles, you can ensure that you are safe next time you are using a vehicle with an electric brake. Electric brakes might sound more complicated than regular vehicle brakes, but now that we have explained in further detail, we hope you are feeling confident next time you are handling any industrial vehicle that is equipped with electric brakes.

4 Thruster Brake Benefits

Despite a decrease in overall production and sales, the steel industry still produced a whopping $17.4 million dollars in 2019 revenue. This is only one industry that uses industrial brakes in its day-to-day operations, with other metal manufacturing plants also regularly using these brakes. No matter how you look at it, industrial brakes and clutches- including thruster brakes- are here to stay.

If you’re looking to increase production value at your plant, look no further than thruster brakes. Read on to learn some of the essential thruster benefits so that your business will be booming in no time.

1. They’re Affordable

Thruster drum brakes are an incredibly affordable purchase for your industrial plant, especially considering how much use you’ll get out of them. While there are various financing options for your thruster, you can contact us to get a quote as to how much it’s going to cost you!

2. They’re Versatile

Thrusters are great because they can be used in basically any manufacturing conditions. They can survive high temperatures on their own, but this is made even more possible with the addition of high-temperature kits or silicone fluid.

They can also be used with variable frequency drives since the setting of the brakes can be put on a timer. The operator can also add set and release switches to the thruster, making its operations automatic. This saves you the stress and hassle of manually operating such a large and potentially hazardous piece of machinery.

3. They’re Easy to Maintain

Despite their size and versatility, thruster breaks are incredibly easy to maintain.

These machines consist of two essential parts: a hydro-electric actuator/thruster and the movement. Occasionally, you’ll need to do things like clean and recondition the movement or change out the lining of the brake shoes.

These parts can both be professionally maintained regularly at a meager fee, and they can be refurbished to be like new after even years of use. The fact of the matter is that thruster brakes were explicitly designed for easy maintenance, and they live up to that reputation.

4. Part Replacement Is Easy

When you have a thruster that you’re operating, it’s only natural that it will go through some regular wear and tear. Parts that help the machine operate are going to need to be replaced on occasion, meaning that you’ll need to order new ones. Items like brake wheels, shoes, reline brake shoes, enclosures, limit switches, self-adjust mechanisms, and pins will need to be monitored and replaced at intervals.

We at Kor-Pac sell all the parts and accessories you may need for your thruster on our website. This makes buying new parts incredibly simple, and you won’t even need to pay two shipping fees if you order your parts at the same time!

The Types of Mechanical Brakes and How They Differ

Every day around the world, several types of mechanical brakes are used in material handling, production, and other heavy industries. While you may only think of car brakes, these brakes help the industry that powers our world. 

Types of Mechanical Brakes

Brakes can be divided into mechanical and non-mechanical types of braking. 

Mechanical brakes use friction to slow or stop machinery and wheels. Non-mechanical brakes such as eddy current brakes are also used. 

1. Disc Brakes 

Disc brakes use a rotor that is connected to a shaft. This rotor spins between a caliper, which has multiple cylinders that each can push a brake pad or other friction material onto the rotor. This causes the rotor to slow momentum as friction builds up. 

Disc brakes, in particular, are often used hydraulically. One key area in the debate of hydraulic vs. mechanical disc brakes is the dispersion of heat. Heat is a natural byproduct of arresting momentum with friction, and all brakes heat up while in use. 

2. Drum Brakes

Drum brakes are one of the oldest and most common types of mechanical brakes. A curved bracket called a shoe has the brake pad attached to it. Two shoes are usually inside the drum, and when activated, they press on the inside of the drum, slowing the spinning drum. 

Mechanical load brakes are a form of drum brake used to help hold up a hoist. They serve as secondary brakes to prevent a crane from failing under heavy stress. 

3. Band Brakes

A band brake works by having bands of material that tighten around a moving object. This tightening force causes friction to build up and causes the spinning object or shaft to stop moving. This tightening can lead to excessive heat build-up and isn’t useful in all situations. 

4. Spring Brakes

Industrial brakes come in a lot of shapes and sizes. Spring brakes are mechanical brakes but require air pressure to operate. These brakes remain clamped unless air pressure is applied to open them. This is often called a failsafe brake, as it does not allow a part to move when not intended. 

5. Cone Brakes

A cone brake is one of the types of mechanical brakes that uses a drum, but the internal mechanism is different. Instead of using a shoe that is a bent bracket with a brake pad, the cone brake uses cones. These cones are coated with lining material and push against the drum to halt its momentum. 

Industrial Brakes  

Industrial brakes are used in all areas of operation for many industries. Mechanical PTO clutches are often used with these brakes. Using a clutch, power can transfer from a generator to an auxiliary piece of equipment. This can bleed of energy that would otherwise cause wear and tear on the brakes. 

Good Brakes are Essential 

High-quality mechanical brakes make work more efficient and prevent wear and tear on equipment. Safety is essential to any thriving industry, and Kor-Pak Corporation has the types of mechanical brakes you need for your business to run smoothly and safely.

Types of Rigs: Everything About Offshore Rigs

Around the world, there are 1,470 offshore oil rigs. 

Offshore drilling has become popular because it reaches oil that’s impossible to reach from the land. To reach different areas of the environment, many types of rigs now exist. The variation in each rig’s design comes from the kind of challenge it’ll face in the area it’ll be drilling in. 

Types of Rigs

The types of rigs used in offshore drilling are distinct from the kinds of oil rigs on land. Offshore rigs must be able to endure the rigors of the ocean. There are seven types of drilling rigs used in offshore drilling. 

1. Barges

Barges are flat-bottomed boats that stick to shallow water. In offshore drilling, this type of drilling rig gets oil from shallow waters. These rigs are not suitable for heavy seas or deep-water drilling. Built-in equipment on the boat serves as the housing for the operation.

2. Drill Ships

Drillships differ from barges in that they’re designed for heavier seas, and the drilling occurs through the boat. A ‘moon pool’ is in the center of the drilling ship through which the drill descends and raises. This makes the ship a vehicle and unique amongst the types of rigs. 

3. Platforms 

There are several types of oil platforms used, but they follow the same principle. These types of rigs are built on supports that anchor to the bottom of the seafloor. Multiple directional wells can be dug from them, and many have a moveable substructure that can shift position to accommodate new wells.

4. Jackups

Jackups look very similar to most offshore platforms. The difference lies in that they’re not permanently attached to the seafloor. The name describes their action, as the legs can be jacked up to move or jacked down to drill. 

5. Submersibles

Submersible drilling rigs are unique amongst the other types of rigs in that they’re designed to go underwater. This barge-like drilling rig can lower its hull under the water using extensions. They are designed to work in deeper water than traditional barges and are more stable. 

6. Semisubmersible

This type of rig is usually extensive and requires towing to reach their destination. Semisubmersible drilling rigs have cranes, hoists, helipads, and living quarters. Once pulled into position, they set up and lower their floater pontoons under the water to stabilize drilling. 

7. Floaters

Floaters are drilling rigs that float on the surface of the water. They require special equipment to stabilize the drilling rig and protect it from the waves. These rigs can easily move from location to location. 

Offshore Oil Rigs

As more drilling is done offshore, industries that cater to oil and gas drilling must adapt to their customer’s needs. Kor-Pak Corporation can service and provide equipment as well as repair to any of the various types of oil rigs.

No matter what types of rigs you use, using the proper equipment and keeping it in good condition is essential to safeguard the lives of those who work on these offshore oil rigs.

What is an Industrial Clutch and How Does it Work?

In America, the manufacturing industry is currently thriving. In fact, not only does the manufacturing sector employ more than 12 million people directly, but it also allows for millions of other jobs to be indirectly sustained because if the goods manufactured.

For the manufacturing industry to continue to grow, plants must be supplied with the latest and most efficient equipment for getting the job done. One of the most necessary pieces of industrial equipment is a clutch. 

What Is an Industrial Clutch?

At the most basic level, an industrial clutch is a device that you attach to your machinery that controls the transmission of power within it. It can engage and disengage the power transmission of various large machines within a manufacturing area or plant, usually altering the power transmission between the driving shaft to the driven shaft.

There are a few key types of industrial clutches. Industrial drum brakes are one of the most common. Drum/shoe brakes operate under most industrial conditions and conform to AISE or DIN standards. There are also DISCK or-Pak brakes that can furnish even the highest of Torque requirements. Storm brakes also exist, and they’re ideal for extreme heat or cold weather conditions. These brakes are also mountable and can be beamed or mounted against walls.

How Does It Work?

Clutches connect to two rotating shafts within a mechanical device. These come in the form of either drive shafts or line shafts. In any case, one of the two shafts (called the driving member) will be attached to an engine or another type of power unit. At the same time, the other shaft (named the driven member) provides the output power to make the clutch work.

Most of the time, the motions that these shafts go through are rotary, meaning that they spin in a circle to make the clutch function properly. There are, however, some that move in a linear fashion.

Industrial clutches have a lot of working parts, but fortunately, it’s possible to easily replace or refurbish those that might need it at Kor-Pak. Make sure to perform regular maintenance inspections on your clutch and ensure that you’re as productive with it as possible.

How To Check a DC Motor

Unplanned downtime lasts an average of four hours and can cost companies about $2 million.

The good news is that if your issue is with a DC motor, troubleshooting one is pretty easy. That said, you should know what to do before something goes wrong so you can get back up and running as soon as possible.

Read on, and we’ll tell you how to check a DC motor if you run into problems.

1. Disconnect the Motor From the Power Source and Prep the Wire Ends for Diagnostics. 

Use a screwdriver to remove the set screws from the wire connections running between the motor and battery. Once removed, disconnect the wires so the motor can’t get power.

If necessary, expose the ends of the wires so you can use them to complete the test circuit. 

2. Detach the Motor From Its Machine Housing. 

Remove the DC motor from its machine housing so the rotor can move freely during diagnostics. Depending on the motor type, you’ll either have metric or SAE bolts, so make sure you have the right tools for the job. 

3. Prepare the Volt-Ohm Meter for Testing. 

Set the volt-ohm meter to its ohms setting. Plug the red volt-ohm meter lead into the ohms point, and the black lead into the ground point. Attach the alligator clip leads to each motor power input wires. Touch the two leads together and ensure the volt-ohm meter reads zero ohms. 

4. Run the Test: How to Check a DC Motor for Defects.

Touch the exposed wires of the motor with the volt-ohm meter leads. Black goes to black and red goes to red. Now, read the screen and determine the results:

10 to 100 ohms: This is a low resistance range and indicates there is nothing wrong with the motor.

Infinite ohms: This means there is an open circuit and requires further testing.

5. Rotate the Motor’s End Shaft and Take Note of the New Readings. 

Slowly rotate the motor’s shaft.

If the meter readings change while the shaft is in motion, the motor is good, but there’s a problem with the circuit.

If the meter readings still show an open circuit, there’s an issue with the motor. In most cases, you’ll find it’s one of three issues:

  1. A short in the ground
  2. Bad conductive bushings
  3. A failed commutator

6. Test for a Short in the Ground. 

Find a metal part of the frame’s motor and attach the black alligator clip to it. If the meter shows an open circuit, there is a short in the ground.

7. Remove and Inspect the Bushings. 

Locate the motor bushings under the plastic end caps on the other side of the driveshaft. Use a screwdriver to remove the bushings and then inspect them.

Look for cracks or breaks across the surface of the bushings. There should be a smooth curve where the bushings sit against the commutator.

If you find no defects, the problem is usually the commutator.

8. Remove and Inspect the Commutator. 

Remove the two screws that run the length of the motor and take off the rear end cap. Inspect the plates that make up the commutator assembly.

You should see an opening between each plate and no broken wires or burnt varnish. If you find anything else, the commutator has failed, and you’ll need to replace the damaged parts.

What You Need to Know About Hydraulic Assist Brakes

Brakes are all around us. You can find them in cars, trucks, windmills, and just about any piece of industrial machinery. 

Brakes come in all forms, from drums to rotors to electromagnetic to hydraulic.

Keep reading to learn more about how hydraulic assist brakes work and where you can find them. 

Hydraulic Assist Brakes: What Are They?  

Hydraulic assist brakes came about in 1973 and are also known as hydro-boost power assist brakes. They work as an alternative to vacuum boost assist brakes.

Before hydraulic brakes existed, brakes in vehicles used a vacuum booster, drawing pressure from the vacuum system in the engine.

With hydraulic assist brakes, hydraulic pressure from the power steering system in a vehicle or from a different system in the machinery provides the operator with an assist in applying the brakes.

You would typically use hydraulic brakes for three different reasons: 

  1. Your vehicle has no vacuum source available. This is often the case with a diesel engine. 
  2. You do not have enough space for a power-assist device. 
  3. Your vehicle requires more braking assistance than a vacuum booster can give you. 

How Do Hydraulic Assist Brakes Work? 

In a vehicle, hydraulic assist brakes rely on the pressurized fluid that powers the power-steering. The hydraulic brake system will have a line plumbed in with the steering gear.

The power steering pump then supplies pressurized fluid for both the power steering gear and the hydraulic assist.

In short, when you apply the brakes, a spool valve that controls the fluid will move and allow pressurized fluid to assist in braking. This spool valve has a bore that creates a seal and yet still allows just enough fluid to provide the lubrication necessary for effective braking. 

Logically, then, if something would cause a loss of pressurized fluid to the steering, you would lose your brakes as well. However, a hydraulic system will have a backup or reserve.

Let’s say a hose breaks, a belt snaps, or a pump fails, and you lose pressurized fluid in your steering. With a hydraulic assist system, a high-pressure accumulator or back up will store enough power steering fluid for two to three power-assist stops.

That’s the basics of a simple hydraulic brake system. Hydraulic brake systems have evolved since the 70s, though.

Take air over hydraulic brakes, for example. In this case, the system uses compressed air and hydraulic pressure to make the brakes do their job. These brakes have a special air-over-hydraulic power cylinder with an air cylinder and hydraulic cylinder that work in tandem to make brakes function efficiently.

Where Do We See Hydraulic Brakes? 

Hydraulic-assist brakes work well in vehicles, but engineers see other uses as well. For example, a typical windmill brake in a wind turbine used to rely on rotors, but some turbines now have hydraulic-assist brakes. 

Industrial brakes can benefit from hydraulic brake technology. Past braking systems used drum brakes, which could overheat. Engineers are developing brakes where hydraulic oil is circulating behind the brake pads to keep the brakes from seizing. 

Larger, commercial vehicles typically employ air brakes. This system uses compressed air to activate the brake system as opposed to the compressed fluid in a hydraulic system. Smaller, domestic vehicles will use hydraulic over air brakes. 

Brake with Fluid

Hydraulic assist brakes provide an additional safety feature to just about any vehicle.

3 Different Types of Earth Movers Used in the Mining Industry

Did you know that every year, on average, each American uses 40,000 pounds of newly mined materials? Mining and the stuff we get from it are essential to our way of life; it’s a vital industry.

The mining industry uses all types of machines for various stages of the mining process. Here are three pieces of earthmoving equipment that are used to help move earth and excavate the land.

1. Excavators as Mining Equipment

An excavator is a standard piece of heavy industry machinery used as earth moving equipment. Excavators can be seen in most construction jobs, from mining to building sites. An excavator is a piece of machinery that uses hydraulics to function and has a long arm with a bucket attachment.

The standard excavator has a cab for an operator and can be driven using wheels, or the more familiar tracks. An excavator can be used for many types of construction jobs and fitted with special attachments most suitable for each project.

Excavators are used in mining to remove earth and materials like coal. They work by digging with a hydraulic arm and hauling away with a bucket. Many different types of excavators are used in both small and large scale mining operations. 

2. Commercial Grade Equipment Backhoe Loaders

Backhoe loaders are another standard piece of heavy machinery used in mining and construction. This piece of earthmoving equipment is convenient because it’s three components built into one piece of equipment. Backhoe loaders are typically driven on wheels with a cab for the operator.

Backhoes consist of the following three components:

  • Backhoe
  • Loader
  • Tractor

Having this one piece of machinery that’s equipped with the above elements is helpful, especially on sites where there’s limited space for various pieces of machinery. 

3. Dump Truck for Moving Earth 

Dump trucks are also used as earth moving equipment in mining. A dump truck usually has a large open bed that lifts at the front near the cab. This allows the vehicle to dump its materials that may include anything from sand to coal.

Haul trucks are extra-large dump trucks used explicitly for industrial mining. These trucks are heavy duty and used to haul large quantities of mining materials and even other equipment. 

Excavators on your job site will use a dump truck to haul away earth materials that are extracted by them. The bigger the excavator, the more earth moved, and the bigger your dump truck needs to be.

3 Simple Ways to Avoid Machine Failure on Your Commercial Equipment

Whatever your industry, the cost of broken machinery is an expense you can do without — the downtime resulting from broken machinery results in billions upon billions of dollars of lost revenue every year.

That’s why one of the smartest capital decisions you can make is to safeguard and maintain your equipment.

Spending a few hundred dollars (or even less) on upkeep for your operating machinery is a lot less painful than the tens or even hundreds of thousands you will spend in the event of an industrial machine failure.

If you’re wondering how to keep all of the gears running, here are three straightforward ways to avoid machine failure. 

1. Implement a Condition Monitoring System for Your Operating Machinery

Any responsible industry veteran will tell you that a rigorous condition monitoring system is essential. Put simply, condition monitoring involves using data and analytics to continually keep an eye on the health of your operating machinery. At its most basic level, condition monitoring consists of placing sensors on all of your machinery.

Thes sensors will all be connected to a central monitoring platform that can usually be accessed on a tablet or laptop. The sensors will continuously provide updates on your machinery and alert you to any real or potential problems.

Conditional monitoring sensors prevent commercial equipment breakdown by monitoring aspects such as machine vibration, temperature, acoustics, and lubrication.

By being able to monitor the health of your machinery, you’ll be able to catch any issues before they become serious problems. 

2. Detect and Destroy Any Defects

It’s not enough to act whenever a question arises. There are steps you can take to prevent commercial sector equipment failure before any malfunctions occur. If you’re using second-hand machinery, try and find out if the previous owner experienced any issues with the equipment.

Even with brand-new, top-of-the-line equipment, there will likely be preemptive measures you can take. For example, if a particular brand of a gearbox is known to work better with certain types of lubricant, make sure only to use those types.

Even getting in touch with equipment manufacturers for advice on how to avoid wearing machinery down can go a long way.

Every piece of machinery has optimum environments. Take steps to find out what these are, as well as which situations are more likely to cause deterioration.

This preliminary step may save you a lot of time and money further down the line. 

3. Routine Maintenence is Key 

Lastly, it’s essential to incorporate routine maintenance into your work schedule. Even machines that are in perfect working order should receive at least essential maintenance on a regular or semi-regular basis. This doesn’t have to be a particularly strenuous ordeal.

For example, setting up a schedule for tightening screws and applying lubrication to moving parts once a fortnight or so can prove more than sufficient. Even the best sensors cannot always predict when a machine will break down.

That’s why you need boots on the ground to perform regular maintenance. Even if there is no work to be done on a machine, merely having a human set of eyes checking the equipment is an essential preventative measure.

More Than Just Large Cranes: 5 Types of Hoisting Equipment in the Construction Industry

The construction equipment market will grow to $89.3 billion next year.

It’s easy to see why. A job is only as good as the tools used to construct it. But with so many different tools out there, it’s essential to get the right ones for the job.

Read on to learn how to tell your large cranes from your moveable pulleys.

1. Movable Pulley

A pulley consists of a wheel on a shaft (or axle) that supports movement. It also supports a change of direction or a belt (or cable) along the wheel’s circumference.

They’re used in many ways to transfer power, apply force and lift things. A pulley is also called a drum or a sheave. Sometimes it has a groove between the two edges of its circumference for the belt to sit. Belts consist of cable, rubber, rope, or chain.

2. Rope and Pulley

The rope and pulley have been in use since antiquity and is most suited to lifting heavy loads and loads with rough surfaces. Usually, the ropes are chain or wire. For hoisting operations, an alloy chain works best.

The weakest part is the load hook – the hook securing the chain to the load item. This can straighten out and fail. When you notice straightening on the hook, you should replace it to avoid accidents.

3. Chain Hoist

This system consists of chains made into two sets. These are the load chain and the hand chain. Hand chains are useful for remote, isolated locations where electricity isn’t available. The force applied from the hand chains transfers over to the load chain.

Chain hoists use a load cook to secure the load as well as a support hook. This supports the mechanism. You shouldn’t interchange these hooks, though. The support hook is stronger than the load hook, so if changed, the load hook won’t be up to the job of supporting.

4. Tower Crane

These cranes are of the swing jib type and usually mounted on steel towers. The towers can be up to 30m tall. Tower cranes are best utilized on tall buildings that are being built in built-up areas. This is because they need a minimum ground area.

Tower cranes combine the best parts of a log boom from a derrick crane and mobility from mobile cranes. The rotating part is an outer framework.

The boom is then added to the front end of this. A counterweight balances out the back end. Two motors at diagonal points on the base are what gives the middle shaft movement.

5. Derrick Crane

There are two types of derrick crane — guy derricks and stiff leg derricks. There is a vertical mast on a guy derrick, and the number of guy wires supports it.

It has a 360° movement. Usually, they’re powered by electric or diesel motors. Guy derricks can have a 200-tonne lifting capacity. Stiff leg derricks replace the guy wires with a trussed structure. The carrying capacity of stiff leg derricks is between 10 to 50 tonnes.

From Large Cranes to Moveable Pulleys — Know the Difference

Each piece of hoisting equipment is suitable for different jobs. Hand chain hoists are great for off-the-grid locations. While guy derricks are capable of handling huge loads for big projects.
