and partly a boxvan has been supplied by Lawrence David Ltd of Peterborough to Wavin Plastics Ltd of Hayes.
The idea is to shorten and simplify the vehicle loading procedure.
The forward sections of the trailer sides are fitted with Lawrence David's Roller-Sider lift-up curtains, operated by small winding handles on the front bulkhead.
Towards the back, the body sides are panelled in aluminium alloy like an ordinary boxvan, with access through the rear doors.
The design allows lengths of plastic piping to be carried in the rear section, and pallet cages of brackets, clips and fittings can be side loaded at the front. To allow extra-long sections of piping to be carried, there is an overlap between the two sections.
The raised step-deck is 3m (9ft 10in), but the Roller-Sider compartment extends back a further 2.8m (9ft) with its floor at fore deck height over the main deck to form a pocket ahead of the rear compartment so that pipes of up to 7m (23ft) may be carried.
