Widening Trailer for Heavy Haulage

Scheuerle offers a wide range of reliable and well-engineered, width-extendable vehicles. These transporters guarantee operators cost-effective operations. 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 vehicle has to cross several state lines, and it is possible that the axle spacings or vehicle width must be changed immediately upon crossing the border. Doolan’s Heavy Haulage is, therefore, relying on the Widening Trailer from Scheuerle, which stands out through an extremely high bending moment even when fully extended.

The Widening Trailer transport system from Scheuerle was developed specifically to meet the requirements of the Australian and American markets, with the new Highway Giant-Dual Lane Trailer recently added to the product range. Due to the variable width of the vehicle, the loading area can be adjusted to 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 a gooseneck or drawbar. The Widening Trailer relies on the Scheuerle pendulum axle technology. The twin-tire 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 to 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°, allows easy maneuvering even when negotiating tight bends.
