Chocks: Get Heavy Duty Rubber Wheel Chocks and Blocks on Sale
Chocks are blocks or wedges that get used to secure a wheel and keep it from moving. They can be rubber, urethane, wood, or even metal. Wheel chocks have a very important job for ensuring safety. Without tire chocks in place, serious accidents can occur if the vehicle rolls away from its secured place. Choosing the appropriate chock for the job is important because tire chock needs vary depending on the size of tires to be secured, the weight of the vehicle and the grade. As a general rule of thumb you want to use wheel chocks that are 1/4 the height of your tire but check your vehicle owner's manual to be sure. TrafficSafetyWarehouse.com offers a wide variety for all needs, including military wheel chocks, roadblock chocks, airplane chocks, trailer and truck chocks .
Wheel chocks are used to keep a vehicle from rolling when the opposite end is lifted or when a larger vehicle (or plane) is parked to protect against property damage and injury. Off road chocks are also used in construction so workers can park vehicles on non-paved terrain that may be uneven.
Choosing a Wheel Chock
There are several factors to take into consideration when choosing the appropriate wheel chock to use:
Usually you will choose a wheel chock at least 1/4 the height of the tire
Weight of the Vehicle
Heavier vehicles will need heavier duty chocks and possibly use more than one.
Grade of the terrain
Steeper grade will require either heavier duty chocks, more chocks or both.
Tires with higher air pressure may decrease rolling resistance.
Type of tire
Radial tires vs bias ply tires, radial tires can reduce the chock's effectiveness
Condition of the Ground
If it is firm, wet, frozen etc. Frozen or wet ground for example may require more chocks, heavier weight bearing chocks or chocks with different grip.
How to Safely Use Wheel Chocks for Vehicle Lifting:
Park the vehicle on a level surface.
Set the parking break
Determine which way the vehicle would roll when you lift the end.
Place the chock securely between the ground and the back end of the wheel (furthest away from the side you are lifting).
Kick/push the chock toward the wheel to make sure the fit is secure.
Do the same on the opposite side of the same wheel and make sure it is secure.
It is best to secure both wheels with chocks to ensure maximum safety.
