VAWDREY Trailers has become known as one of Australia's major manufacturers, supplying a wide range of rolling stock from curtain-siders through to refrigerated vans to skels, and is developing a name for specialised combination construction.

A stunning looking quad- quad super B-Double combination taken up in Victoria for container haulage to Melbourne's wharves is being built by Vawdrey to performance based standards.

These fully-approved super B-Double skel combinations have been provided to transport companies such as Arrow Transport Logistics and Quarantine Services.

Now accepted under Victorian legislation, the super B-Doubles reduce the number of single truck movements, giving fuel and maintenance advantages to the company.

Arrow Transport has been reported as saying that where two trucks used to carry two 40-foot containers, that task can be carried out by one super B-Double unit.

The heavy-duty trailers are built on a high-tensile steel chassis so that the skels can reach a gross combination mass of 77.5tonnes, making them suitable to carry two 40-foot containers with an overall payload of 54tonnes.

In addition to increased weight capacity, each of the super B-Doubles is fitted with the latest electronic braking system (EBS), quad-quad suspension and rubber mud flap guards, giving maximum payload and the ability to travel city and suburban routes seven days a week.

To answer the issue of potential scrubbing with the quad axle groups, the lead axle is steerable, a condition demanded by the National Heavy Vehicle Regulator in assessing the PB standards for the equipment.

The PBS combinations mean less vehicles are doing the same work in an urban area, with flow-on environmental benefits as well as more efficiency and unit-per-tonne-carried cost against the overheads of fuel and labour.

The Vawdrey quad-quad super B-Double is an indication of PBS vehicles with bigger trucks and bigger payloads with little increase in on-road and highway wear and tear.
