Quality friction material, adequately selected according to its attributes, is crucial to daily safe operations of your business. Scan-Pac Manufacturing produces a wide array of products to suit your needs. Read on to learn more.

Fact and Friction

The need for friction materials drives a global market that’s projected to increase at a Compound Annual Growth Rate (CAGR) of 5.2% between 2019 and 2023.

The worldwide value will reach nearly $24.7 billion by 2023, according to a recently published report. So, friction is not a slippery slope by any stretch!  

By way of definition, friction materials are used in systems that require direct contact pressure between two or more parts to control speed.

Obviously, due to direct contact during use, friction materials wear down and become less effective over time. However, the rate of wear varies. Different materials have predictable capacities for wear and performance under specified conditions (such as temperature range encountered, speed requirements et al.).

What Are the Different Types of Cranes and Which One Is Right for You?

Cranes help us lift heavy objects with ease.

Without them, getting construction and manufacturing jobs done would be more difficult and time-consuming.

There are different cranes for different situations, and it’s important to know which one is right for you.

Continue reading to learn about the various types of cranes.

1. Mobile Crane

The mobile crane is a telescopic boom on a mobile platform. The fact that this crane has mobility makes it versatile. It’s a standard part of bridge, building, and highway constructions.

2. Floating Crane

This kind of crane is mainly used for offshore jobs and remains in a fixed position. They have a high lifting capacity of 9,000 tons, making it possible for them to get entire sunken ships out of the water. They are for bridge and port constructions.

3. Telescopic Crane

A telescopic crane incorporates hydraulics to change the height of the boom. These types of cranes are especially good at lifting objects to or from a high place. A telescopic handler crane has something like a forklift attached to the end.

4. Harbor Crane

A harbor crane is located in ports. It loads and unloads ship materials safely because of its power. They can have a lifting capacity of around 154 tons.

5. Crawler Crane

The advantages of the crawler crane are that they move on tracks and can lift up to 3,500 tons. They’re able to work on hard or soft dirt because of the tracks.

6. Rough Terrain Crane

Rough terrain cranes are like they sound. They are for off-road construction sites. They move on four large tires and have one engine that powers the crane and the undercarriage.

7. All Terrain Crane

All terrain cranes can have the same purpose as a rough terrain crane, while also being able to work on a smooth surface. They can have 8 to 18 tires. This larger amount benefits the balance of the vehicle that moves the crane.

8. Truck Mounted Crane

These types of cranes are great for a site that requires a crane for a limited number of things. The crane is mounted on a truck, so it can travel on highways rather than needing another truck to transport it. The lifting capacity is up to 50 tons.

9. Level Luffing Crane

A level luffing crane is fixed in a shipyard. It has a hinged jib that moves the crane hook inwards and outwards while keeping it level. These cranes unload ships and move cargo containers.

10. Railroad Crane

Railroad cranes are designed to travel on railroad tracks for maintenance and repairs. The boom can reach up to 100 feet and can lift 250 tons.

11. Aerial Crane

Aerial cranes are moved by what looks like a helicopter. The actual crane is a series of cables that attach to and carry material. A large advantage is that they can pick up or drop off a load at any place.

An aerial crane might be used to bring materials to a skyscraper or rescue a ship crew in the middle of the ocean.

12. Tower Crane

These cranes are used for constructing tall buildings and can reach from 230 feet to 265 feet. They are attached to the ground by concrete and bolts.

Connecting them to the building in construction will stop the crane from moving and possibly falling over. Their lifting capacity is up to 20 tons.

13. Loader Crane

A loader crane is an addition to a truck or trailer that is used to load materials in the vehicle or unload them. The crane can be compacted when it isn’t needed. The highest lifting capacity is 200 tons.

Choosing from the Types of Cranes

To pick the type of crane that is right for you, consider the kind of job it is and where the site is. Never forget crane safety when operating a crane. If you have any questions, contact us by filling out a form or call (888) 256-7725.

Your Ultimate Guide to Understanding Limit Switches

Limit switches have provided safety and security for industrial applications for approximately 100 years. The technology has evolved, but it remains mostly the same. Many of the old Cutler-Hammer and Square D designs are still in operation.

In the following article, we’ll be discussing this simple yet life-saving (and cost-saving) device in all its glory. Let’s start the motor.

What Is a Limit Switch?

Let’s start with the Occupational Safety and Health Administration. According to OSHA, a limit switch is defined as a device designed to “cut off the power to the motor and apply the brake to stop the carrier if a loaded step passes the terminal landing.”

The most common use of a limit switch is to limit travel of heavy loads attached to a crane. Over the years, other applications have benefitted from the device, such as conveyors, hoists, and heavy moving machinery.

The goal is to prevent over-travel and maintain control throughout the motion of the load. The first limit switches entered the industrial market in the 1920s. Today, they serve industries like:

  • Steel
  • Auto
  • Intermodal/rail
  • Manufacturing
  • Mining

You’ll find them in shipyards, ports, factories, and industrial plants. They’re also available on consumer products, with the most obvious that comes to mind being the electronic garage door opener at your house, if you have one.

The Basic Functions of a Limit Switch

A limit switch only does four basic things, but they’re important ones. It senses the location of an object, the motion, the positioning, and the end-travel.

Many “crane fails” occur due to a breakdown in these functions. For example, a crane is hoisting a megaton-load at a top rate of speed. Given the heaviness of that load, the crane will need ample warning before the load reaches the top, so it knows to slow the speed.

A breakdown in the contact that controls speed would send the load full-throttle to the top of the crane. The abrupt stop would cause a violent shift and a probable break.

But let’s say the speed contact is fine. It’s the stop limit that’s deficient. In this case, the travel of the load might slow, but the operation would continue working to hoist the load, thus bringing about unsafe positioning/swaying.

Most limit switches also contain an “ultimate” stop limit that acts as an override to the stop limit. If it and the stop limit are damaged, the same result will occur.

Parts of a Limit Switch

Most limit switches are composed of actuators, connectors, seals, enclosure cases, and a built-in basic switch. Here’s a bit about each one:


External force and movements need to be communicated to the basic built-in switch. This is the component that makes that connection.

Built-in Basic Switch

This component switches an electrical circuit. The electrical circuit allows the limit switch to operate without the need for manual involvement.


These protect the internal mechanics of the limit switch, securing the cables and outside connection.

Enclosure Casing

This mainly protects the built-in basic switch from external pressure. It, too, is vital for the overall operation.


These primarily protect the built-in basic switch and internal components. Since cranes and conveyors often operate in harsh environmental conditions, these are essential for the integrity of the limit switch as a whole.

The interconnectivity of all these components is essential. Therefore, limit switches must be inspected and maintained regularly.

Limit Switches: Essential Safety and Security Components

Limit switches have made industrial and electrical engineering applications safe for workers and the environment for a century. And it’s not changing any time soon.

So don’t overlook this small but essential part. And while you’re at it, make sure you take these additional steps before your next OSHA Inspection.

How to Choose a Clutch That’s Right for Your Machine

In simple terms, a clutch is a mechanical device connected to two or more rotational shafts. When the clutch is engaged, power is transferred from the engine to the wheels.

Choosing the right clutch for your machine is essential in terms of saving you time and money. You cannot afford to have your heavy machinery break down because the clutch isn’t up to the job.

To make the right choice, it helps to know what the different components are and how they work together to affect performance. Keep reading to learn more.

Components of a Clutch

There are several clutch components, the largest parts being:

  • Flywheel
  • Clutch disc
  • Pressure plate

Springs, release levers, covers, bearings, and pins are also used to make up the complete clutch assembly.

The Flywheel

The flywheel stores rotational energy and when the clutch pedal is pressed it provides inertia to allow continuous rotation.

Clutch Disc

This is the part that gets the most wear and tear because it absorbs the load when engaged. There are two types of clutch disc; sprung hub and solid hub.

Pressure Plate

The pressure plate is another hard working part. It forces the clutch disc against the flywheel via springs when the clutch pedal is engaged.

Clutch Disc Material

This part is more likely to wear first, so it makes sense to choose the correct material for the application.

A solid hub clutch disc is primarily used for high capacity engines, such as racing. These hi-performance clutches have heavy-duty springs to absorb the load caused by the higher engine capacity.

Most other applications use a sprung hub clutch disc. It is designed to absorb and spread shock on initial engagement and throughout its use.

Materials used for discs include, organic, Sintered iron and Kevlar. Organic materials are present in most stock clutch discs.

Sintered iron is used for its non-slippage ability.  It can withstand extremely high temperatures, so it’s good for applications that require dynamic stopping. It can also be resurfaced if slippage becomes a problem.

A Kevlar clutch has a higher friction force, but this can result in rougher engagement and some vibration in low gears. That said, it is an incredibly hard-wearing material.

Torque and Response Time

The job of a clutch is to transmit torque without slippage. The heavier the load, the more likely slippage can occur. This is what causes wear and tear.

Response time is how long it takes the load to reach a specified time.

There are several factors affecting torque and response time.

Depending on the application, full torque during acceleration may or may not be needed.

The ability to disperse heat is also crucial and affects every instance of clutch engagement.

Buying a Clutch

Now you know what goes into choosing the right clutch for your machinery. Of course, you want to get it right the very first time.

That’s where we can help. We’re experts in all kinds of industrial clutches. We can advise you on size, torque, style, and application.

5 Essential Heavy Machinery Maintenance Tips

Put these tips to work today and keep your business running smoothly and efficiently like the well-oiled machine it is.

1. Don’t Overwork Your Machines

It’s essential you know the limits of your machinery and re-check it every once in a while. Know the performance specifications and limitations before using the equipment.

If you’re unsure of this information, consult the manual or manufacturer. Never allow parts to get so worn down that they break and harm your operators or start a fire.

2. Protect Your Machinery from Weather

You probably know that machinery left in the rain will cause rust and corrosion but did you also know that direct sunlight can harm your machines too?

If possible, store or protect your machinery away from wind, rain, snow, and sunlight to ensure optimal and safe performance. It’s best if they’re stored in a cool, temperature-controlled, moisture-free area out of direct sunlight.

3. Keep Up with Routine Checkups

There’s nothing more important than regular maintenance checks on all of your equipment. Do not forget to lock out tag out to avoid injuries accurately.

During regular maintenance checks, look for signs of wear, leaks, cracks, or any other kinds of damages.

4. Clean Often

One of the easiest ways to keep your equipment safe is to keep it clean. This means regular removal of dust, dirt, grease, rust, and product corrosion.

Keep a special eye on vents, filters, and electrical equipment that they are clear and clean to avoid the risk of injuries.  

5. Don’t Forget to Lubricate

If you’re looking to extend the life of your machinery, you’ll need to lubricate.

The lubrication process reduces friction, reduces the risk of equipment wear, and keeps the internal parts clean and running smoothly. Keep a regular lubrication schedule and always make sure you’re using the right kind of lubrication for your machine.

Hang Tight: How To Maintain Your Small Mobile Crane

The most common cause of crane accidents involve issues with the boom, the hook-lift, and heavy counterweights.

Operating a crane is difficult and requires expertise. Owning a crane, however, requires regular maintenance, a keen eye, and diligence.

If you possess a crane and want a quick introduction to small mobile crane maintenance, this article is for you. Here, we break down some of the best actions you can take to keep your machinery up and running.

Ready to find out more? Add these items to your checklist.  

Maintaining a Small Mobile Crane

Although some maintenance is required by law, understanding what to look for and when to do it saves you lots of money in the long run.

1. Use the Logbook

It seems obvious, but this is too important to gloss over.

Use the logbook, and have every single operator use it, too.

This ensures if anything suspicious pops up, it’s logged so that you have a clear foundation for troubleshooting. Furthermore, logging lets owners see the last time the machinery was inspected.

Logging makes keeping track of routine and required maintenance much simpler.

2. Lubricate Regularly

Lubricating the main parts, especially the boom, is easy. Unfortunately, not many workers do it.


Because it takes a few hours, however, those couple of hours are nothing compared to the lost production you’ll suffer if your crane stops working.

Lubricate the following once a week to maintain optimal performance:

This weekly step saves owners money and time in the long run.

3. Conduct Pre-Operation Checks

It doesn’t take long to do a visual check of the crane before operating it. Make it a company policy to conduct an inspection using a checklist that adheres to your model.

Some points to consider for these inspections include:

  • Fluid levels
  • Cracks
  • Any oil or grease on the clutch lining or brakes
  • Tire pressure
  • Fastener tightness and stripped threads
  • Rust or wear, especially on the chassis

These visual checks alert operators to any problems before they begin work.

4. Replace Filters and Oil

Contaminants are the biggest enemy to hydraulic machinery. That’s why it’s important you not only check for contaminants each week but also make sure you’re replacing filters and oil on time.

Follow your manual’s guidelines. If you replace these too early, you’re spending unnecessary funds. If you replace them late, you might have bigger things to worry about.

Don’t forget to check the air filters regularly.

5. Conduct Overload Tests

A standard error that results in injury is overweighted cranes. Therefore, conduct overload tests with every inspection for optimal crane safety.

Overload tests are mandatory in certain circumstances, but by conducting one with each primary inspection, you’ll increase production and keep workers safe.  

Since it’s a common issue, it’s well worth the investment.

Hang Tight for More

These starter tips help owners of small mobile cranes form good habits. With these five suggestions, you’ll enjoy more production, greater safety, and fewer repairs.

Owning a crane comes with responsibility. Part of that accountability involves understanding the equipment you and your employees work with.

Although this article provides excellent starter information, there’s much more to learn.

The Advantages of Portable Engine Hoists

Forklifts, cranes, and hoists, oh my! Industrial engine moving options are plentiful. So which do you choose?

There are advantages and disadvantages to each, but in this article, we’re going to focus on the benefits afforded to you with portable engine hoists. Keep reading to learn more!


Let’s start with one of the more obvious advantages, shall we? It makes sense that portable engine hoists would be, well, portable.

These types of hoists make it easy to transport heavy and bulky engines to different locations. The hoist itself is also designed to be easily moved to various areas.


These hoists are versatile in their power source as well as their application.

In terms of power, they can be powered manually, with air power, or with electric power. Electrically powered hoists are the fastest and most efficient, allowing workers to rest instead of manually lifting heavy loads.

They can also use chains, rope, and wire to lift engines and other industrial parts, so it can be customized for each project on which material will work best.

Certain types of portable engine hoists also allow you to lift and move things both vertically and horizontally, which other moving machines aren’t able to do.


Compared to other types of cranes, hoists, and machinery, portable engine hoists (especially those that are electrically powered) tend to be quieter. This can be a relief on many job sites and industrial areas that get loud.

Can Handle Heavy Loads

Perhaps the most important advantage of using hoists is that they can handle heavy loads that workers can’t handle on their own. Instead of overworking people and tasking them with manually transporting heavy engines, hoists make it quick, simple, and easy, no matter how large the engine is.

Whether you’re moving small motorcycle engines or huge oil rig machinery, these industrial hoists can handle it.

Durable and Long-Lasting

We know what you might be thinking: this is yet another piece of machinery that you’ll have to maintain and eventually replace.

But that’s what makes these types of industrial hoists so great: they have fewer parts and components compared to larger cranes, trucks, and other types of industrial movers. This means they’re more easily maintain, are more durable, and require less maintenance.

This, in turn, means that they’re long-lasting and will serve you long into the future.

Those Advantages of Portable Engine Hoists Sound Great… But What About the Disadvantages?

Durability, portability, and versatility are three buzzwords when it comes to industrial machinery. But portable engine hoists are far from perfect, even if they fulfill those three desirable characteristics.

Before you buy, read our article on some of the most common crane/hoist problems that people face.

You can also contact us with any questions you still have about these types of hoists, if you want more clarity on the advantages/disadvantages, or if you’re ready to buy!

How To Safely Use An Engine Hoist in the Workplace

Have you heard the slogan, “No Safety, Know Pain?”  How about “Safety Rules Are Your Best Tools?” Safely operating anything should always be of primary concern.  Here’s how to safely use an engine hoist in your shop or workplace.

First, this.  There are three main types of engine hoists.   These hoists can be used for other heavy lifting applications besides engine removal.  

Types Of Engine Hoists

The most common type, the hydraulic engine hoist, is mobile (it rolls on casters) and can be used indoors or outdoors, as long as there is a flat, hard surface.  

Construction of a hydraulic hoist consists of a primary vertical post to which other parts of the hoist are attached.  There are two horizontal legs with casters which allow the hoist to roll across the floor (or your driveway).

The top of the hoist has an extendable center boom, often with locking positions for different engine compartment depths.  At the end of the boom is a steel grab hook. That is where lifting slings or chains can be attached to your engine.

A hydraulic cylinder located in the middle of the hoist and attached to the boom and the main post performs the lifting action.  You use a handle and pump it to increase pressure in the cylinder (just like a hydraulic jack for changing a tire).

The other two types are the manual chain hoist and the electric hoist.  These two both require fixed mounting above ground (usually to the ceiling or special scaffolding) to perform their lifting action.  So, they are not considered portable engine hoists and are more commonly used in other applications.

Overall, the excellent lifting capacities of hydraulic hoists (typically 1 to 2 tons, but with greater capacities available), their mobility, and their ease of maintenance make them ideal for both professional and do-it-yourself mechanics.

We will focus on choosing and safely using hydraulic engine hoists.  

Safety Tips

1.  Choose Proper Lift Capacity

When selecting a hydraulic hoist, it’s best to opt for one which has a greater lift capacity than what your engine weighs.  So, even though your engine doesn’t weigh 2,000 lbs, you should buy a hydraulic hoist rated for 1 to 2 tons.

Why?  The laws of physics tell us the actual weight capability of the engine hoist decreases as you extend out the hoist’s boom.   It’s the lever principle.

So, you need to know what your engine weighs, and then purchase your hoist accordingly.  Here is a representative sample of engine weights for cars.

Hydraulic hoists also come in foldable models so you can collapse them for storage purposes.  This is ideal for do-it-yourselfers because you can free up space in your garage once the engine has been safely extracted and placed onto an engine stand (or wherever you are planning to work on it).

2.  Assemble Your Hydraulic Hoist With Care

Hydraulic hoists are relatively large, so they usually come disassembled. Be sure to follow all assembly directions from the manufacturer closely. Figure on a timeframe of up to two hours, depending on instruction detail.  Make sure to double check tightness of all nuts and bolts.

Now, read the instruction manual and ensure you understand how to operate it!

Okay, so your hoist is assembled, you know how it works, and you are ready to lift out your engine.  Here we go.

3.  Clear Your Workspace

Position your vehicle so that there’s plenty of room to maneuver the hydraulic hoist around it. Make sure there are no obstacles that would hinder safe footing and freedom of movement.  Organize all tools and necessary equipment.

Make sure your work area is clear of unwanted persons (especially children).  Wear proper attire – no loose-fitting clothing or jewelry that could snag on the hoist mechanism.

Secure the vehicle (i.e., with the parking brake) to ensure no unwanted movement during the engine removal process.

4. Operate Your Engine Hoist In A Safe Manner

  • Disconnect, store, and label all engine and transmission mounting bolts, as well as connections for hoses, wires, etc.  Take pictures, if it will help you.
  • Find a spot at the rear of the engine where you can attach the chain or lift slings you are using. This could be the exhaust manifold bolts, or any other location that you are sure can support the weight of your engine. Consult the owner’s manual for your vehicle for recommendations.
  • Find a spot at the front of the engine to attach the other end of the lift slings or chain. Align such that the engine stays level as you lift it and loose enough that you can connect to the hoist hook.
  • Center the hoist on the engine and connect your lift slings or chains to the hoist hook. Start raising the engine slowly (by pumping the hoist jack handle) to be sure everything in the engine bay is properly disconnected.
  • Keep pumping the handle until the engine is clear of the vehicle.
  • Move the hydraulic hoist slowly and carefully to where you want the engine to rest for maintenance purposes.
  • Word to the wise:  Do NOT get under the engine while it is being moved to the engine stand or blocks.  You are tempting fate if you do.
  • Slowly and carefully lower the engine onto the engine stand or blocks, by turning the bleed valve a little bit at a time.
  • Make sure the engine is properly secured in its holding device before removing the lift slings or chains.

Stay Alert – Don’t Get Hurt!

Hydraulic engine hoists are safe to operate and very effective in what they do for you, provided you follow this simple guide.

Your Guide To Dynamic Resistors

Trains and the locomotives pulling them can weigh anywhere from 40 tons to 500 tons depending on the number of axles. And, as you can imagine, the heavier the train, the harder it is to slow it down.

It takes massive amounts of energy to slow down a heavy mechanical system.

Before dynamic braking systems, we used to apply mechanical force manually. Someone would run down to the end of each car and turn a wheel applying the brakes. This often didn’t work fast enough, and trains crashed.

Primarily since the advent of the diesel engine, we use more reliable systems to slow down mechanical systems.

Trains might be the most common example, but you’ll find dynamic braking systems in elevators and cranes too.

To help these systems to operate quickly, smoothly, and efficiently, engineers created dynamic resistors. Without resistors, these systems would be clunky and possibly dangerous.

Here are the various features and specifications of this all-important braking component.

1. What Does a Dynamic Resistor Do?  

There are two kinds of dynamic resistors. One is rheostatic or dissipating, and the other is regenerative.

Dissipating braking resistors essentially recycle kinetic energy and turn it into electrical energy. The energy in the case of trains comes in the form of heat.

This energy returns to the supply line where it overloads the circuit and slows down the mechanical system. This is a lot like using your manual transmission to help slow your car down a steep grade.

If the resistor is rheostatic, its main function is to cool the braking system. But even these resistors can become overheated forcing operators to revert to mechanical systems.

Often dynamic braking systems use both kinds of resistors.

Unfortunately, dynamic braking isn’t sufficient on its own to slow down a massive train. Most systems combine dynamic brakes with air brakes.

2. What Are the Advantages of Dynamic Braking?

Friction braking systems do work. On their own, they can stop a train. But on a steep grade, they’re less reliable.

The other problem with friction systems: they wear down faster.

Just like car brakes, mechanical brakes on a train eventually wear down. When adding the extra force from dynamic motors, you extend the life of the friction braking system.

Speed. That’s the most significant advantage of adding electrical braking to your system.

You slow down faster. But this also means you can push your train to go faster.

The second most significant advantage is cost. Not only will you use less energy to slow down the train, but you also won’t have to replace components like brake shoes.

Lastly, because you’re converting heat energy into electrical energy or dissipating heat through resistors, there is less chance of fire or failure. Mechanical brake systems cause too much heat when not assisted. This means your brakes are more likely to fail.

Dynamic Resistors Are Important

Dynamic resistors are incredibly crucial in train operation. You won’t likely find a contemporary locomotive without this kind of braking system installed.
