Installation Advice

Whilst we can provide installation images using our own vehicle collection,  it is vital that the placement/position of our products - particularly the Wheel Chocks, is relevant to your vehicle and trailer setup. We use grade 80 high tensile bolts with nylock nuts or spring washers- and the length of the bolt is determined by the trailer floor plate thickness.

The correct loading of heavy vehicles is vital in the prevention of injury to drivers and members of the public and the prevention of damage to materials and equipment.  Vehicle loads must be sufficiently restrained to prevent movement from the forces arising from the vehicle passing over road undulations, changing direction or when it is being braked or accelerated. It requires much more force to stop a load that has started moving than it does to prevent the movement in the first place. It is essential that the load is restrained to prevent movement in any direction relative to the vehicle. Friction between the load and the vehicle platform cannot be relied on to make a load secure. Dynamic forces will tend to exceed such frictional forces and render a load insecure. It is therefore necessary to provide additional restraint to prevent the load moving. This restraint is normally provided by means of lashings secured to the vehicle chassis and load platform or by various baulking arrangements such as loading racks, headboards and chocks.

The official New Zealand truck loading code [PDF, 8.4 MB] will provide the the correct information regarding load restraint requirements.
