Ground Vehicle and Aircraft Wheel Chocks

Wheel chocks are blocks specially designed to fit the contour of tires and withstand the operating weight of the vehicles, aircrafts and equipment. The primary function of a wheel chock is to immobilize the wheel of stationary vehicles, aircrafts and equipment to prevent any roll off or accidental movement, which can cause serious and costly personnel injuries as well as asset damages, during maintenance work, loading/unloading and even parking on ground or roads with gentle slope or in a windy area.

No doubt an unchocked runaway vehicle can cause serious injuries and damage properties, a driver driving off with their wheel chocked can be just as bad. Hence, our Terra Chock® Wheel Chock Warning Stand series featuring wheel chocks fitted with warning stands or handles to provide wheel chocking function and serve as reminders to drivers and ground staff to remove the chocks before driving off.

Omni Technosys Pte Ltd stocks and distributes a wide range of high quality ground vehicle wheel chocks for cars, vans, lorries, buses, trailers, scissor lifts even 400 tons mining trucks and aviation chocks for helicopters, executive jets, fighter jets, airliners up to and including Airbus A380.

Terra Chock® Wheel Chock Warning Stand Series

Ever experienced truck drivers, in their hurry to their next destination, driving away with their wheels still chocked?

Such incidents could potentially lead to personnel injuries and properties damages. And, such incidents usually happen when the drivers forget that their wheels are chocked. As checking rear view and side view mirrors before driving off come naturally to drivers, having wheel chocks fitted on warning stand can help remind the drivers that their wheels are chocked as they are able to see the wheel chock warning stand in their side view mirror.

At Omni Technosys Pte Ltd, we developed a series of wheel chock warning stands that can provided both wheel chocking functions as well as serve as a reminder for drivers that their wheels are chocked just before they drive their vehicles away.
