Safety features in new Hanger low-weight tanker

• A new tanker designed for the collection of waste corrosive products has been introduced by Hanger Engineering Ltd, of Warwick. A development of the lightweight glass reinforced plastics tanker introduced a year ago, it incorporates new safety features to prevent spillage and a novel system of pre-selecting the load capacity to comply with MoT regulations.
The load selector system enables operators to choose a 1500. 1600 or 1700 gal capacity load by simply moving a selector lever on a control panel. Mercury probes within the tank sense when the tank has reached the predetermined levels and an electro-pneumatic system of valves cuts out the air supply to the vacuum pumps.
In common with the original tanker, the new g.r.p. model has a weight reduction advantage as compared with tanks made of mild steel, stainless steel or aluminium. For similar tensile and flexular strength the saving in weight can be in the order of between 10 and 20 per cent.
Hanger Engineering believes it is the first company in Europe to produce successfully a Celmar lined tank with integral baffles to reduce surging to the minimum, thereby maintaining optimum vehicle stability. Anticipating future safety regulations, no tank apertures are placed below the liquid level line. As the material to be carried frequently contains acid or alkali, a drain system is incorporated in the hose boxes feeding to a 10-gal sump tank at the rear of the vehicle. Any spillage from the rear door is caught within a tray which also feeds into the sump. For the safety of both operators and the general public, a separate 50-gal clean water supply fed by an electric pump is available to wash off corrosive materials. The outside of the tank is finished with a smooth fibre skin. Tanks are available in 1450, 1750 and 2000 gallon capacities.
Mr Robert J. Shove, managing director, Hanger Engineering Ltd, announcing the new tanker said: "We are getting more and more industrial waste and there is a growing market for us in this field. The tanker has been designed with future regulations in mind on the carrying of acids and the like on the highways."
Two g.r.p. tankers have been sold to America and inquiries have been received from Japan and Australia.
