Urethane Aviation Wheel Chocks

Urethane Wheel Chocks for Small and Large Aviation Airplanes and Aircraft

Urethane aviation wheel chocks from Checkers feature an impact-absorbing design that is ideal for a variety of small and large aircrafts. These wheel chocks are constructed of an exceptionally durable urethane that is resistant to weather and abrasion as well as aircraft fuels, oils, and lubricants.

Urethane wheel chocks are uniquely designed to eliminate foreign object damage. Unlike wood wheel chocks, urethane chocks will rot or splinter. These wheel chocks are available in a roped-pair or single-chock option.

The high-visibility colors used to manufacture these wheel chocks can be seen from great distances and in a variety of weather conditions. Aviation wheel chocks are ideal for securing heavy equipment or aircraft and protecting personnel from injury.

Frequently Asked Questions

What are aircraft wheel chocks?

Aircraft wheel chocks are essential safety devices that prevent an aircraft from moving while it is parked. They are placed in front of and behind the aircraft's wheels. While wood, rubber and polyurethane are commonly used for aviation wheel chocks, there are many advantages for choosing polyurethane or rubber over wood chocks, the most important being overall safety.

How much do aircraft chocks weigh?

Aircraft wheel chocks vary in weight according to the size of the chocks. Checkers aviation wheel chocks are constructed of highly durable yet lightweight polyurethane. Both our polyurethane and rubber models are sold as singles with a rope or roped together as pairs. Single polyurethane aviation chocks range from 1.5 to 15 lbs. for small to midsized aircraft, and from 13.9 to 43.25 lbs. for large and oversized aircraft. Single rubber aircraft wheel chocks range from 6.5 to 14.4 lbs. in weight. It is important to note that, unlike wood aircraft chocks, urethane or rubber chocks are non-absorbent and will not become waterlogged in rain conditions or freeze to the ramp during cold weather.

What are aircraft chocks made of?

Checkers aircraft chocks are made of impact-absorbing polyurethane that is weather and abrasion resistant, as well as resistant to aircraft fuels, oils and lubricants. These lightweight chocks are easy to use with a military-style rope-lock system and optional rope carrying handle. The chock-to-chock rope lock system allows a wheel chock to be temporarily and securely attached to the opposing wheel chock on the opposite side of the plane’s tire, to ensure the wheels chocks remain firmly positioned against each side of the tire during engine test procedures. Checkers also supplies solid rubber wheel chocks featuring a triangular design constructed of high-density rubber resistant to UV, moisture, salt and oils.

How much space must be in between aircraft tires and chocks?

When an aircraft is parked, it is important that is doesn’t move. Checkers recommends using aviation wheel chocks to prevent unwanted movement. The chocks should fit snugly against the tire, with no space available in between the wheels and the chocks for the wheel to rotate.

Where is the preferred location for placing chocks on an aircraft?

The safest option is to place chocks on all wheels of an aircraft, which includes the nose wheel, main wheels, and tail wheel. At a minimum, chock all wheels that have landing gear assemblies. Aircraft wheel chocks should be placed on both sides of the aircraft to ensure that it does not move during maintenance or servicing.

Why do we chock an aircraft?

Chocking an aircraft is an important safety precaution that helps prevent the aircraft from moving while it is on the ground, which could cause injuries or damage to the craft. Chocks are typically placed in front of and behind the aircraft's wheels to help keep the plane in place. Aviation wheel chocks can also be used to secure other parts of the aircraft, such as the nose gear, to help prevent the aircraft from moving.
