COMPREHENSIVELY equipped for repairs to tyres and wheels, a special light-alloy van built by Wilsdon and Co., Ltd., Solihull, and mounted on a Cornmer forward-control oil-engined 7-ton chassis, is employed by the Dunlop Rubber Co., Ltd., for servicing work at car and motorcycle race meetings.
The main compartment has four fitting benches for servicing wheels, and a smaller compartment at the front
houses an electrically driven tyre-cutting machine for grooving the covers. The floor ,level above the front wheels is supported on a steel frame, which is integral with beds for mounting the heavier equipment.
Alternating current for operating the equipment is supplied by a Petbow 230-volt generator driven by a small petrol engine, which is located in a sound-insulated compartment under the bulkhead panelling. A Bullows electrically driven compressor is connected to a long air line with quick-release couplings at a number of points inside and outside the vehicle. Other equipment includes an electric drill, vice and three trolley jacks.
The front compartment has a side entrance for which draw-out steps are supplied, and the entrance to the main compartment is at the rear by means of a walk-up ramp. Side canopies hinge upwards to form shelters. The roof is insulated and has natural Perspex lights and Weathershields ventilators.
