A NEW lightweight tri-axle air suspension system has been produced by SAF of Germany.
Comprising three eight tonne axles, the trailer suspension weighs about 1,600kg (3,530Ibs). It is said to be lighter than all existing mechanical leaf spring suspensions. The specification incorporates many of the proven components employed in the company's standard models, and is the first step in a programme to reduce weight. Operation is limited to on-road use. The suspension is not suitable for tipping or ro-ro work. It may incorporate a self-steer axle to reduce tyre scrub.
The increase in maximum. operational weights to 38 tonnes last year has given a boost to sales of air suspension. Many benefits are claimed in tyre and brake wear as well as providing a more sympathetic ride to the load. Probably most significant is the inter-axle load equalisation properties.
TIP, Europe's largest trailer rental company, already has 200 air suspended trailers. It is to equip all future purchases of 38 tonne semi-trailers with similar suspension.
SAF claims that in 1965 it became the first in Europe to mass produce air suspension systems. SAF is an Oe supplier to all major UK and European semitrailer manufacturers. In the UK, Industrial Machinery Suppliers, of Loughborough, has sole marketing rights.
