Scheuerle’s Widening Trailer proves itself in the toughest of Conditions in Australia

PFEDELBACH/GERMANY, June 26, 2014 - Statutory provisions regarding load distribution on roads and bridges vary considerably depending on country or state-specific legislation. For example, in Australia or North America, it is not unusual that a transport has to cross several state lines and it is possible that the axle spacings or vehicle width must be changed immediately on crossing the border. Doolan's Heavy Haulage chose therefore to rely on the Widening Trailer from Scheuerle, which also stands out through an extremely high bending moment even when fully extended.

The Widening Trailer transport system was developed specifically to meet the requirements of the Australian and American markets, with the new  "Highway Giant - Dual Lane Trailer" being recently added to the product range. Due to the variable width of the vehicle, the loading area can be adjusted to the suit the size of the cargo. Furthermore, the distribution of the total weight can be influenced during a transportation assignment so that different regulations can be complied with using just one vehicle. In order to achieve an optimal payload/tare weight ratio, the bogies are manufactured using a solid lightweight construction. Connecting to the tractor is carried out by means of a gooseneck or drawbar. The Widening Trailer relies on the proven pendulum axle technology from Scheuerle.

The twin-tyre axles are pendulum-mounted on hydraulically lifted rocker arms. The hydraulic cylinders in the pendulum axles guarantee, on the one hand, larger axle compensation and, on the other, a large displacement volume in order to also be able to drive under and pick up supported loads when in the normal drive position. The Scheuerle pendulum axle mounting, in connection with the precise and smoothly-operating steering system with a steering angle of up to +/- 60°, easy manoeuvring even when negotiating tight bends.
