Continuing development is perhaps a phrase which most haulage people use in connection with engines. gearboxes. axles and other Mechanical components. But most other units which go to make up the structure of a road vehicle are continually subjected to redesigning and evaluation in much the same manner as are their mechanical counterparts.
John Smith and Co. (London) Ltd. is well known for its activities in the manufacture of lorry tilts and sheets and the like: it has recently supplied four to Lep Transport made in a new material which bears the trade name Topspan. This is claimed to be lighter in weight and to have a higher tear strength than traditional materials, and it is manufactured by the Plastics division of Winterbottom Products of Salford, Lancs.
Topspan is a p.v.c.-coated nylon and it offers excellent weather protection. It retains its flexibility over a wide range of temperatures and due to its hydrophobic behaviour (it will not absorb water), its weight is not increased during a rain storm. The material readily accepts paint used for stencilling and signwriting, providing that this is of a p.v.c.compatible type.
Stringent regulations to combat interference and pilferage of cargoes travelling under a TIR carnet are adequately served by the new material as it can be welded as well as stitched.
