Under the Road Traffic Act, it is the sole responsibility of the driver to ensure the load and any ancillary equipment (e.g. the loader crane and any attachments) are securely stowed for travel.
Loader cranes and attachments should always be stowed as per the manufacturer’s recommendations.
Hook cranes should be folded and stowed using the designated stowing brackets.
For loader cranes fitted with a brick grab, clamshell or other attachment that prevents the crane from being folded, in the absence of manufacturer or employer instructions to the contrary:
The loader crane should be stowed in a horizontal position over the body, with the attachment resting on the vehicle bed (if the vehicle is loaded, clamping the attachment to a load is not considered as a sufficient means of security. Strapping should be used at all times).
Boom extensions should be fully retracted, as this minimises wear and tear on the components during travel and reduces any swing or whiplash effect on the loader crane when cornering.
The attachment should be opened to its widest extent and placed so that the rails / attachment sides are running fore to aft down the vehicle body.
Very importantly, the attachment should then be secured by means of a ratchet strap or equivalent, to prevent the loader crane from moving during transit and coming into contact with the vehicle sides / breaching the extremities of the vehicle. The only exception to this is where the vehicle sides are designed to withstand such forces.
