• A novel Wilcox tipping semitrailer with Crane Fruehauf rolling bogie chassis is attracting considerable interest in the West Country.
Built for the Glendinnirtg group in Ashburton, the triaxled sliding arrangement, normally a feature of container work, allows the axle's position to be varied by 1,400mm.
This, says Clifford Glendinning, improves manoeuvrability and stability.
"With the bogie in the 'short' manoeuvering position and the front bogie axle raised to improve traction on site, the combination will go most places that an eight legger can," he says. The 7.31m, 21.4m monocoque body gives Glendinning a 23-tonne payload.
It widens slightly towards the rear to assist with load ejection; its forward sloping rubber sealed tailgate ensures that it does not dig in as it tips.
Instead of the conventional bolster, a hinge bar is used for the Edbro DS18 top-lift ram.
