Signs You Need to Replace Your Industrial Drum Brakes

When’s the last time you checked your industrial drum brakes?

If the brakes on your machinery aren’t working, they can bring your entire production system to a halt, costing you huge amounts of money. That’s why it’s important to keep them in check with regular maintenance.

In this post, we’ll tell you how to do that. Read on to find out how to check drum brakes and what the tell-tale signs of failure are.

How to Check Drum Brakes for Damage

When you’re carrying out brake maintenance, these are the signs you should be looking out for.

Noise

Noise is one of the first signs of bad drum brakes.

They may come in the form of squeaks, scraping, grinding or screeching sounds.

These usually occur when brake shoes are worn down. When they’re worn down completely, brake discs and calipers will start to rub together, causing scratching and other damage. An accumulation of dust and dirt may also cause noises.

When your brakes are in use, listen out for any abnormal sounds. If you notice any, you may need to replace some parts. Do this as soon as possible to prevent any further damage.

Otherwise, you’ll have to spend time and money replacing other parts as well as your brake pads.

Less Response than Usual

If your drum brakes are working correctly, you should feel them respond by slowing your machinery as soon as you press down on the pedal, lever or button required.

If they’re beginning to wear down or fail, their responsiveness will start to wane. You’ll notice that their ability to slow things down will be reduced, and you may have to apply more force to get the desired effect.

This is one of the most common signs of brake failure in vehicles and with machinery, the same rule applies.

Pulling

Do you feel as though certain parts of your machinery are pulling to one side when you operate the brakes?

This is a common sign of uneven wear on drum brakes. However, it could also be caused by problems with your brake fluid. Either way, it’s an easy fix. You’ll have to drain and adjust the brake fluid, replace the brake shoes, or perform a brake adjustment.

Vibration

If you’re noticing vibration occurring when you apply your brakes, you should check the rotors immediately. This is a sign that they’ve become warped.

This happens when brakes have been used for long periods of time or with great force. During brake use, rotors are subjected to large amounts of friction and heat.

Over time, they’ll begin to warp out of shape. As a result, they won’t sit flush to the brake pads, and that’s what causes those vibrations.

Inspect and Replace Your Drum Brakes

If you’re experiencing any of the above problems, it’s time for some brake maintenance.

You may need to adjust them. However, if things are serious, you may need to replacement altogether.

If you’re not sure how to check drum brakes, maintain them or replace them, we’ve got you covered. Read our guide to installing and replacing drum brakes for all you need to know.

Reasons Why You Need Custom Machining

You’ve been searching high and low for parts and equipment that are just right, but you just can’t find them.

Sound familiar?

You’d be much better off taking matters into your own hands and having them custom-made.

In this article, we’ll tell you why you should use custom machining instead of settling for what’s already on the market.

The Benefits of Custom Machining for Your Business

Here are just some of the things you can do when you have custom machined parts.

Fabricate Parts With Special Requirements

From time to time, your equipment will require parts that require custom fabrication.

These may include quick turn-around projects, which require additional parts, supplies, and manpower to fulfill. They can also be custom orders. Projects will often request unique parts not available in manufacturers catalogs.

If you don’t have the resources to carry out these projects, you’ll lose business. However, if you have resources available, you have the potential to take on special projects and improve efficiency.

Custom machining allows you to create ‘made-to-order’ parts and products, keeping your operations running and improving.

Replace Discontinued or Obsolete Parts

Some companies use devices and machinery for years or even decades. This means that by the time they come up for maintenance, fixing or replacement, the parts you need may no longer be on the market.

This can pose quite the challenge for manufacturers. Some will take existing parts and attempt to modify them to make them fit for your purpose. However, this is rarely successful.

If you have custom machining, the problem can be easily fixed. We can provide reverse engineering services to recreate discontinued or obsolete parts that you need but can’t find elsewhere.

You don’t have to shop around for the parts that are just right. Instead, you can have us fabricate them for you.

This will get your machinery up and running quickly.

Work with Difficult Materials

Some materials can pose problems during the production process.

For example, plastics generally require sophisticated CNC machining equipment. Certain metals, such as bronze and stainless steel, can also require specialized parts and equipment. You can’t just put them through a standard process and expect to get the results you need.

That’s why you need specialized equipment, which includes parts and machinery that are specially made to carry out the processes you provide.

Streamline Your Production Process

When you have custom equipment, you don’t have to rely on anyone else.

You no longer have to order pre-made parts and deal with suppliers. This means you save yourself time and money. If there are last-minute changes to requirements, you can make the adjustments you need as quickly as possible.

This gives you a more efficient production process with a faster turn-around time.

How to Know When You’ve Got a Faulty Industrial Gearbox

Most industrial gearboxes last for around 20 years.

However, that’s only if they’re taken care of properly. Along the way, you’ll have to keep an eye out for transmission problems and fix them right away.

If you’re not what they are, don’t worry.

In this article, we’ll go through the tell-tale signs of a faulty gearbox.

Signs Your Gearbox Is Causing Transmission Problems

If your gearbox is exhibiting any of these issues, it’s cause for concern.

Noise

A faulty gearbox will often start making noises.

These sounds could be caused by parts rattling or grinding together. Bearings, gears, and shafts accumulate wear and tear over time, and as they do so, they’ll produce more and more noise.

If you notice that your gearbox is noisier than it once was, it’s worth checking it out. Experienced engineers can use the type of noise to identify the root of the problem.

For example, loose motor mounts are often the culprits for banging and clunking sounds, faulty bearings usually cause low-pitched rumbling noises, and damaged gear teeth can produce high-pitched screeches.

Overheating

Is there a significant difference in the temperatures of the housing and shaft of your industrial gearbox? This could be a sign that something isn’t working correctly.

Other signs of an overheating gearbox include smoke emitting from shafts and seals, discoloration of surfaces caused by burning and melting of plastic parts.

Lubrication may not be working effectively. It should increase the longevity of parts by cooling them and reducing friction. If that’s not the issue, overtightened bearings could be creating too much friction and heat.

Cracks

If you see cracks or other visible damage to your gearbox, you need to have it looked at immediately.

This can be caused by vibrations that occur when the speed and torque of the gearbox are increased. Loose, broken or poorly mounted parts will vibrate aggressively, eventually causing damage to other parts or shifting out of place.

Misalignment

Over time, parts can move out of their rightful place and become misaligned.

This can be caused by wear and tear, vibration, and heat expansion. However, the root of the problem may have occurred at the point of installation.

If the gearbox that has been installed isn’t fit for purpose, it will cause problems later down the line. Similarly, if it isn’t mounted correctly, it’s likely to break down much more quickly.

Oil Leaks

Check the shaft seals of your gearbox. If you notice that oil is starting to leak out, you have a problem.

When the seals become compromised, oil will seep out, and water, dirt, and dust are being allowed in.

Even if you can’t see a leak, check your oil levels. If they’re suspiciously low, you may have to search for a leak somewhere else. Faulty gaskets can also cause leakages.

Keep Your Gearbox in Check

If transmission problems are left for too long, they can bring your production process to a complete halt.

That’s why you need to keep your gearbox in check with regular maintenance.

Carry out inspections at regular intervals, and you can fix your gearbox issues right away. To find out how to do that, read our ultimate guide to gearbox maintenance.

How to Repair and Preserve Your Crane Wheels

The life cycle of a working crane’s wheels is a stressful one.

With the amount of pressure and movement they withstand day in, and day out, crane wheel maintenance is paramount.

When it comes to preventative measures to keep crane wheels in fine working order, here are some of the most important you should know.

How to Keep Crane Wheels in Working Order

A working crane is a host to a set of polyurethane or carbon steel wheels which play a vital role in the function of the crane.

This set of wheels refers to a runway system upon which the crane sits, moving along a track- also known as rail wheels.

Despite being manufactured from a seriously tough material, they still require regular maintenance. Otherwise, you could be faced with severe downtime.

Typically, gantry crane wheels are manufactured from polyurethane while other wheel materials may include alloy, low-carbon steel or medium-carbon steel.

The higher the rate of carbon in the steel, the more robust a crane wheel will be.

Heat treated carbon wheels also make for extremely hard-wearing wheels, increasing their load capacity and lifespan.

Some of the most common preventative measures to preserve your crane wheels include:

1. Changing Drive Wheels in Pairs

Most commonly, spare wheels are kept onsite in the instance where a rail wheel must be replaced.

But it’s essential to always swap out the drive wheels of a crane in pairs, and not as singular wheels.

This may seem like a waste, especially if the other drive wheel is still in relatively good working order. But failing to do so will lead to crane alignment issues down the line.

Just because the opposite drive wheel is not showing any visual signs of wear and tear, doesn’t mean it’s in 100% working order.

Nine-times-out-of-ten, it’s also very close to failure because it has been under counteractive strain.

Mainly, your crane drive wheels need to be precisely matched in diameter to avoid crane skew, flange and rail wear.

According to the CMAA, the safety standard is that the matching drive wheel must be .001 per inch in diameter with a maximum of .01 inches.

2. Misaligned Crane Runways

This can lead to what is commonly known as crane skew and misalignment issues.

If a reputable professional does not install your crane’s runway system, this can lead to significant issues with not only the wheels but entire crane system.

When a crane is not tracking correctly along the runway, this causes damage to the drive wheels, runway beams, and support structures.

This type of crane damage can ultimately lead to:

  • Crane derailment or complete failure
  • Prolonged equipment downtime
  • Expensive repairs and replacements
  • Serious or fatal job site accidents

A crane that fails to track correctly puts excessive strain on the wheels, wheel bearings, and wheel flanges. This can also contribute to damage to the crane’s motor drives.

If you notice any of the following signs, your crane runway may be misaligned:

  • Broken or cracked wheel flanges
  • A high rate of wear and tear on drive wheels, bearings and rails
  • A higher rate of power needed to maneuver the crane along the runway
  • Wheels that float over the rail, then crash down
  • Loud, scraping noises as wheels travel along the runway

The best way to preserve your crane wheels is to ensure your crane alignment is regularly inspected by a reputable third-party. These third-party experts will be able to safeguard your crane is in compliance with CMAA standards and is entirely safe for operation.

The Applications of Industrial Vibrators

Industrial vibrators make processes faster, more efficient, and more effective.

Whether your industry is farming, construction, food production, shipping, or storage, you can benefit from these devices.

In this article, we’ll explain the many ways they are used.

Common Uses for Industrial Vibrators

Mechanical vibrators make everything easier. Read on to find out how.

Improve Dust Collection Systems

Many production lines require dust to be collected and removed. A mechanical vibrator is often part of this process.

Dust can be removed from the production line and collected in bags, cyclones, or even electrostatic precipitators. Once it’s been collected, a vibrator can be used to shift the dust out of the system and into a waste receptacle.

Merely opening a hopper or chute and allowing the dust to drop out on its own isn’t enough. Vibration is required to shift dust that sticks to the sides and into crevices and clear it completely.

This same principle is applied when using vibration in dump trucks. The force allows contents to be shifted and released more easily. Vibration is more effective than pounding, which can cause unnecessary damage.

Product Quality Control

Industrial vibrators can also be used to carry out shock testing and weatherproof testing on products and packaging during the quality control process.

Vibration frequency can be adjusted to recreate different shipping conditions and levels of impact. This allows testers to see which conditions cause damage to occur.

Compact Materials

Vibration can be used to compact materials, parts, or products before shipping so that they take up less space.

Storage boxes can be placed on vibrating tables during or after the filling process. As the table vibrates, the contents will shift, becoming more compact than they were before. This requires no human input at all and can be done entirely automatically.

This makes the entire shipping process cheaper and more efficient. As shipping volume is decreased, so are your costs.

Compacting is also required in construction work. Soil, concrete, and other materials need to be compacted when constructing roads, foundations, and buildings.

Settle Materials

In food and beverage production, vibration is used to settle materials and ingredients evenly and remove any trapped air and excess water. This is particularly important for chocolate production.

Vibration can also help ingredients flow more efficiently through a production line along feeders and conveyors, and cool and dry more quickly. This prevents any blockage from occurring, so everything can run as smoothly as possible.

Reap the Benefits for Your Business

Now that you know how industrial vibrators can be used, you can identify how to apply them in your business.

The next step is to find out which one is best for you. At Kor-Pak, we supply parts and machinery for just about any use you can think of. See our complete buying guide to find out what you need.

Once you’ve received your order, you can use our industrial vibrator installation guide to get it up and running.

A Guide to Wind Turbine Components

Renewable energy is the future of the energy industry, and wind energy is an essential part of that.

But how do wind turbines and components of wind turbines work?

Read on for details about wind turbines.

The Importance of Wind Energy

The wind has been harnessed and utilized as a source of energy since ancient times when Egyptians used it to propel their boats down the Nile River.

Windmills have been used for farming and other energy sources for over a thousand years.

Now, with non-renewable sources of energy dwindling, we’re starting to use wind energy on a large scale. Since 2000, wind energy has grown by 50 fold, from 6 billion kilowatt-hours to nearly 300 kWh.

How Does a Wind Turbine Work?

A wind turbine has many essential parts, most of which aren’t noticeable from outside of the turbine.

The nose and the blades are the most significant and most visible parts of the wind turbine. The nose, along with the rotor, holds the blades which catch the wind and begin to spin when wind speeds are fast enough.

The main turbine shaft is what connects the blades to everything inside the turbine. This shaft spins at the same speed as the blades and is essential for transferring the wind into energy.

The high-speed turbine shaft, as its name implies, spins at a much higher speed than the main turbine shaft. This is accomplished by the gearbox, which connects the two turbine shafts, and increases rotational speeds through a series of gears, much like how a bicycle increases its rotational speed through the gears attached to the back wheel.

The high-speed turbine shaft is what spins the turbine generator, the essential part of the wind turbine. This generator is what transfers the wind energy into electrical energy.

The inner workings of a turbine generator are complex. Here is a link for details on the inner workings of turbine generators.

There are also several parts of the wind turbine that help optimize the wind capturing process.

The anemometer measures wind speed and works alongside the controller to maximize the efficiency of the wind turbine. These devices can activate the brake to slow down the blades during excessive wind speeds. It can also be used to assist with starting up the blades when wind speeds are too low to activate the blades on their own.

What’s Next?

Now that you can answer the question of “how does a wind turbine work,” you might be curious about other large industrial machines. From oil rigs to overhead cranes, to railroad parts, our blog is an excellent source of information for any energy industry you might be interested in.

What Are Hydraulic Clamps and Why Do You Need Them?

Do you regularly work with industrial equipment? If so, you should be using clamping mechanisms like hydraulic clamps. They’re a vital piece of industrial equipment that will make things in your workplace safer and more secure.

Not sure what hydraulic clamps are or why you would need them for your work? In this article, we’re covering everything you need to know about these clamping mechanisms and how they can improve your work processes.

What is a Hydraulic Clamp?

In basic terms, a hydraulic clamp is a piece of industrial equipment that applies clamping force to secure any workpiece. What separates a hydraulic clamp from a primary clamping mechanism is that these devices use hydraulic fluids as part of the clamping process.

These fluids allow for greater operating pressure, which in turn results in higher clamping even when using smaller clamping cylinders.

What Does a Hydraulic Clamp Do?

If properly designed and used, a hydraulic clamp will prevent any piece of machinery from moving. This means the piece won’t slide or twist in use. A hydraulic clamp also clamps a piece of machinery without distorting the piece of machinery, which may occur when using a more standard type of clamping mechanism.

During the clamping process, a workpiece is positioned inside of the clamping device and held in position. The method of identifying and holding a workpiece is often referred to as “limiting the degrees of freedom” as this relates to the angles the device is constrained to.

Identifying the workpiece is essential for operating a hydraulic clamp correctly. If you do it incorrectly, you run the risk of bending the machine or causing machining error.

How to Operate a Hydraulic Clamp Correctly

As mentioned above, it’s essential to clamp your workpiece correctly. The main thing to do is make sure you’re attaching the clamp to a thick section of the workpiece. For correct clamping, you need to be applying the force to a strong, supported part of the workpiece.

If you attach the clamp to a thinner section of the workpiece, you’ll more than likely bend the piece, which will affect the overall accuracy of machine use. You should also make sure that you attach the clamp in a way that does not obstruct the loading or unloading of the workpiece or the paths of the cutting tools.

If you are clamping to a thinner, more delicate piece of machinery, you should distribute equal clamping force across the machine, and use clamps with pads or softer materials to prevent damage.

Why You Need a Hydraulic Clamp

Hydraulic clamping devices are essential for speeding up processes for industrial work more safely and securely. They reduce non-productive work time, save the operator from the risk of screwing clamps incorrectly, and allow for adjustments that are suited to the specific requirements of the workpiece.

They also reduce operation fatigue and increase machine-tool capacity, which are two vital things you need to improve the scope and efficiency of your work.

Final Thoughts on Hydraulic Clamping Mechanisms

Are you looking to improve your work processes? Want to scale your operations in safer (and more efficient) ways? If you answered yes to either of these questions, you need hydraulic clamping mechanisms.

Everything You Need to Know About Torque Limiters

What if you had to watch your heavy machinery crash into something helplessly?

Many people put a lot of faith into the brakes on these vehicles. But the soft collision protection of brakes is not always enough to prevent a major accident.

For maximum safety, you should be using torque limiter couplings. Here’s our comprehensive guide to what they are and how they can help.

What Are Torque Limiter Couplings?

In many ways, torque limiters are about “just in case” protection. They are designed to protect equipment and personnel in the event of potentially catastrophic damage.

The limiter will have a certain value of torque programmed in. If the amount of torque exceeds that amount, the limiter activates to slow things down quickly.

To know why you should use torque limiter couplings, it’s important to know some of their advantages.

Protecting Workers

As we mentioned earlier, one vital function of these limiters is that they help to protect the workers using the equipment. If no limiter is present, then people using heavy machinery might get into accidents that will hurt or even kill them.

The torque limiter couplings help prevent that from happening. The limiter kicks in before an accident can reach catastrophic levels.

It is as simple as that. Investing in limiters is a way of investing in the safety of every worker who uses that particular equipment.

Protecting Equipment

Of course, the equipment itself is very important. Heavy machinery is very costly to repair or replace. Fortunately, limiters can protect the equipment just as they protect the workers.

Torque limiters essentially offer a kind of grace period for an equipment malfunction. Once the limiter has activated, the worker can shut the equipment down before things can get any worse.

After this happens, you will need to inspect the torque limiter itself and to check the torque settings before you rely on it again. Ultimately, though, it is better to spend a little time doing this than a lot of money on fixing damaged equipment.

Possible Disadvantages

“Nobody is perfect.” This is a phrase that describes industrial equipment just as well as it describes the people using it.

There are a couple of possible disadvantages to the limiters you should be aware of. The first is that limiter settings are approximate, so you must be comfortable with a small amount (usually ten percent or less) of variance.

The second disadvantage is that torque limiter couplings cannot shut the machine down on their own. Instead, the limiters create a very audible slipping noise, and it’s up to the worker to shut down the equipment.

Overall, these disadvantages are minor. And they are far outweighed by the advantages.

The Bottom Line

Now you know what torque limiter couplings are and what they can do. Do you know where you can buy them?

Here at the Kor Pak Corporation, we offer the very best in industrial machinery and parts. To see how we can protect your people and equipment, come check out our torque limiters today!

5 Benefits of Preventative Maintenance

When you work in the industrial industry, you know how much depends on the equipment performing as it should.

One way you can ensure this is by performing regular preventative maintenance on your equipment.

If you’re not yet convinced of the importance of preventative maintenance, we have five reasons that might change your mind.

1. Catch It Before It Becomes an Issue

When it comes to your industrial equipment, nothing is more frustrating than having it malfunction as you’re trying to get the job done.

You will have to stop production to figure out what is wrong with the equipment.

This is where preventative maintenance comes in. Regularly having the equipment inspected might help catch issues before they become a problem.

Regular inspections might help with simple fixes that if left alone could become a problem.

2. Reduces Downtime

Every type of business dreads downtime. Not only does it delay the work from getting done, but it also means having to pay employees for work not getting done.

Downtime could end up costing a lot of money and cause you not to meet your deadlines.

Spending the time and money on preventative maintenance might help alleviate all of that. The machine will be inspected, and you’ll have the assurance it will finish the job is meant to do.

3. Increases Lifespan and Performance of Equipment

Let’s face it; industrial equipment doesn’t come cheap. So why not do everything possible to make sure it has a longer lifespan and performs as it should?

Preventative maintenance might help replace worn down parts and anything else that could slow down the machine. Not only will your equipment last longer but it might also perform as it should.

As machines get older, their performance decreases. This doesn’t have to be the situation if you’re always making sure they work as it should.

4. Reduces Energy Waste

Faulty equipment often wastes more energy than it should, whether it’s overusing the fan because it’s getting overheated or working extra hard to make up for other components not working correctly.

Having preventative maintenance done on the equipment ensures that you only use what you need and don’t waste unnecessary energy. Think of all the money you’ll be saving on energy costs.

5. Protects Your Investment

In a way, think of preventative maintenance as a type of insurance. Since you spent a good amount on your equipment, wouldn’t you want to do everything in your power to protect it?

Making sure the industrial equipment goes through regular inspections is the best way to ensure you take care of the investment.

Depending on the stability of your business, you might not be able to buy it twice. So why not protect it?

Protect Your Equipment with Preventative Maintenance

Preventative maintenance might save you money and protect your industrial equipment. It might also help you reduce downtime and protect your investment but increasing the lifespan of said equipment.

Why Phenolic Plastic Is Great for Bearings

Phenolic plastic has many advantages!

We’ve been using this material since 1907 for telephones, radios, light switches, and more recently, bearings – and for a good reason, it’s excellent.

As you probably already know, plastic bearings are very popular when it comes to metal surfaces. So, let dive into why that is.

1.) They’re Chemically Resistant

One of the reasons phenolic plastic is so popular is because they’re resistant to water, acid, and alkali solutions. This makes them incredibly resilient, and consequently, they’re more likely to stand the test of time.

In fact, the average lifespan of a phenolic product typically lasts as long as 20 years, and in most cases, this plastic needs little to no maintenance.

This makes it both a practical and cost-effective choice because it exceeds the durability of rival building materials.

2.) They Don’t Transfer Heat or Electricity

This advantage is self-explanatory, by being an excellent insulator of both heat and electricity phenolic bearings, help ensure the mechanism doesn’t overheat. Hence, giving the machine structural integrity, and making it less of a fire risk.

As phenolic plastic is heat resistant it makes is way more versatile in comparison to other kinds of plastic. Hence, it can be used in complex mechanisms that require its components to be exposed to higher temperatures.

So, manufacturers can use this material safe in the knowledge that it won’t melt or be a health risk (providing it isn’t exposed to temperatures above 100 degrees Celsius). Plus, this material prevents the spread of smoke- win-win.

3.) Easily Lubricated

The structure of phenolic plastic makes them easily lubricated by water, and oil grease. In some cases, you can even buy self-lubricating phenolic plastic bearings.

Consequently, plastic bearings have since replaced metal bearings in the construction of ships, electrical switch-gear, water-turbine bearings, and clock motors.

This versatile plastic is nicknamed ‘the material of a thousand uses,’ and you can start to understand why when you analyze the list above!

4.) Health Benefits

In comparison to other plastics, phenolics are one of the best when it comes to human health. This is because they’re both non-porous and non-microbial.

Consequently, they prevent the growth of bacteria and mildew. This is a godsend for people who have to work with these products regularly because the air quality won’t be tainted by any dangerous microbes that could cause illness in humans.
