Truck Locks and Trolley Brakes

truck and parking locks

Truck Locks and Trolley Brakes are an easy way to retrofit brakes to an existing trolley or mobile platform or as an alternative to braked castors. The truck locks have a foot operated pad that lowers a pad normally with a rubber surface down to the floor raising the wheels slightly above the ground and providing a friction brake. Also, called “trolley brakes”.

The truck locks act as a brake as the platform or trolley is no longer able to move once the truck lock is engaged. The truck lock can easily be disengaged making it an ideal tool to keep a trolley stable, when loading or offloading.

BZTL series truck locks are of pressed steel construction with a zinc-plated finish (excluding BZTL4 which is cast iron with a black finish)

Truck / Trolley Locks Description

All truck locks are top plate mounted and bolted to the underside of the trolley. The principle on which they work requires a constant gap between the unit and the floor, so it is best to mount the truck lock close to a castor, ensuring that it does not interfere with the free movement and operation of the castor.

A step-down foot-operated pedal moves a skid-resistant rubber pad into friction contact with the floor surface. This is done with a spring-loaded over-cam mechanism that does not lift the load and keeps the operating force low. It also means the load rating of the trolley is not relevant to the truck lock. A second step down pedal raises the footpad. The limited number of parts means there is less to maintain or go wrong.

Where a trolley has four swivel castors, two truck locks are required – one to be fitted at each end, either on the same side or diagonally opposite. Only one truck lock is required at the swivel end of a trolley that has two swivel and two fixed castors.
