6 Most Important Things to Know About Wheel Chocks!

Meaning of Wheel Chocks:

Wheel chocks are small wedges made of rubber, plastic, or wood, which are designed to stop a vehicle (or isolated tire) from rolling or moving accidentally. They are also called wheel blocks, tire chocks, trailer chocks or wheel stops.

Wheel chock is important because a parking brake alone often isn’t enough to keep a vehicle from rolling during a towing job. It’s also important to stabilize tires and vehicles when they’re being transported so they don’t come loose and cause injury.

Types of Wheel Chocks:

Tire chocks vary in four key components. Let’s walk through how these varieties impact the use and effectiveness of a given wheel chock.

A. Materials Used in Wheel Chocks

Wheel blocks can be made out of the following materials.

(i) Rubber:

Rubber is the most common wheel chock material because it’s incredibly durable and inexpensive. However, rubber isn’t very resistant to damage from outdoor elements like wind and water. That’s why rubber wheel chocks are mainly used indoors, like in storage warehouses or garages.

(ii) Polyurethane  Plastic:

Polyurethane plastic is the second most common material for wheel chock. They’re better at resisting cuts, blunt damage, water damage, and wind damage than rubber chocks, and they’re lighter-weight than rubber or aluminum. But, plastic wheel chocks are not as high-strength as aluminum or steel alloy chocks.

(iii) Aluminum:

Aluminum chocks are heavy-duty, and can be used with cars and trucks with a high gross vehicle operating weight. Some aluminum wheel chocks are specifically designed for long-term storage and can be part of a unit designed to mount a motorcycle or car.

(iv) Steel Alloy:

It is the strongest material and can be used with the heaviest vehicles. However, steel alloy chocks can be on the expensive side. Also, steel can be prone to rust, so it’s important to invest in steel alloy chocks that have been treated or plated for corrosion resistance.

B. Surface Texture of Wheel Chocks

Wheel chocks have the following surface textures

(i) Aluminum Teeth:

These teeth, on the bottom of a tire chock, are great for establishing traction in muddy or gravelly surfaces.

(ii) Diamond Plating:

A diamond-plated surface texture increases the friction and “grip” the chock has on the wheel and is designed to mesh well with a tire’s tread.

(iii) Serrated rubber or plastic:

These textured tire chocks are sometimes called “pyramid-style” chocks because they look like small pyramids with “steps” running up the sides. This makes them easy to use on either side. They also require less force that contoured chocks to get traction against a wheel and hold it in place.

(iv) Low-relief plastic or rubber texture:

Typically used with contoured (curved, wheel-conforming) chocks, a low-relief texture provides a bit of additional traction. It doesn’t provide as much grip as other surface textures, though.

(v) Smooth cradle wheel chocks with stand:

A smooth surface on a “cradle”-style wheel chock is only used for vehicle storage. It won’t be used during a lifting or towing job.

C. Size of Various Wheel Chocks

There are four size dimensions to keep in mind.

(i) The steepness of a chock’s incline (or curve). A steeper chock can be wedged in more firmly and use gravity to its advantage, but it can also be more challenging to place–especially if the ground itself is a steep incline.

(ii) Working Load Limit. Do not exceed a wheel block’s working load limit.

(iii) Height and diameter of curve (if applicable). This one’s straightforward: taller chocks work with taller tires, and shorter chocks work with shorter tires.

D. Extra Features 

(i) Handles.

Some chocks come with handles. A low-clearance handle is useful if you’re on a relatively flat surface and the car you’re working on is close to the ground.

(ii) Loop Handle:

Wheel Chocks with Loop Handle

A wheel chocks with loop handle is good for a typical tow job because it lets you grab and move the chock easily.

(iii) Eye Bolt:

Side Eye Bolt Wheel Chocks

An eye-bolt wheel chock can be used to connect different chocks together for a compound effect, or to work with a vehicle that has dual tires on a single side of an axle.

Main Usage of Wheel Chocks

  • Towing
  • Auto-hauling / transporting a car or tires.
  • Repairing a vehicle.
  • Storing tire or vehicle.
  • Keeping airplane stationary while it’s on the airport apron.

How to Use Wheel Chocks Safely While Lifting a Vehicle?

1. Get the right chocks for the job.

Don’t try to improvise a chock using random materials you have on hand. Get the chocks that are suited for the job you need to do. Make sure you have enough chocks to secure all potentially-unstable wheels.

2. Put the car, truck, or motorcycle into park.

If at all possible, parking on a flat surface is best. If you’re on a loading dock, park as close to the dock as possible.

3. Observe

Which way the wheels of the vehicle on the axle you are not lifting are likely to roll, once you lift the other axle.

4. Wedge the chocks under the backs of the wheels

That are furthest from the side you’re lifting. Kick or use a tool to push the chock firmly under the wheel.

5. Place additional chocks on the FRONTS of the wheels

Place the additional chocks on the axle you won’t be lifting, for maximum security.

How to choose the wheel chocks that are right for you?

There are three things to know to choose the right wheel chocks.

1. Know your Job:

Are you lifting a vehicle to tow it? or hauling a vehicle on a flat bed? or storing a motorcycle? Different jobs require different kinds of chocks.

2. Know your Surface:

Whether a surface is flat or steeply inclined, gravelly or smooth, soft mud or hard concrete, there are chocks that you can use to stabilize a vehicle. Make sure you choose the chocks that suit the environment of the job.

3. Know the Vehicle Stats:

If you know how heavy a vehicle is and the size of its tires, you will avoid accidentally damaging tire chocks by surpassing their WLL or overloading a small chock with a big tire.

Conclusion:

Ultimately, wheel chocks are an important safety tool. At Mytee, you can get a wide variety of high-quality tire chocks for less. Stocking up on affordable wheel chocks is just another way to haul safe and earn more.
