Pre assembly cuts costs for Pengco air suspension

PRE-ASSEMBLED air suspension units have been announced this week by Pengco Transport Systems Ltd, which, the company claims, extends the versatility, simplifies, and thus reduces the installation time of its established combined air suspension demountable systems.
A range of jig constructed pre-assembled undercarriage units incorporating 10-ton axles and combined air suspension components has been introduced for Pengco's new range of 24, 28 and 32-ton gcw semi-trailers and 10, 13 and I6-ton gross drawbar trailers.
Former-fabricated 1beam trailing arm suspension members have been replaced with a patented range of heavy spring steel beam links which can be fitted with either 16in convoluted air bellows for standard ± .4 in pivot movement demountable applications, or rolling lobe ± 8in bellows for inter changing body units between high trunking chassis, drawbars and semitrailers and low feeder distribution vehicles.
The independent air reservoirs are designed to provide three complete mounting and demounting movements 72 hours after disconnection from the prime mover to enable drawbar trailer and semi-trailer body exchanges to be conducted with the frame members being manoeuvred with fork trucks. Levelling valves maintain correct road and load ride settings.
Live axle chassis applications have also been simplified by the introduction of spring steel beam links, which incorporate lateral location retaining arms as 'integral members.
