Abstract
A public works appliance comprises a frame, a working attachment coupled to the frame and a control cab. The control cab contains a single control station and is mounted for rotation about an axis fixed relative to the frame. The cab may, therefore, be disposed in a first position in which the field of vision of a driver in the cab enables him to see and control the operation of the working tool, and in a second position in which the field of vision of the driver in the cab is unobstructed by the working attachment so that the appliance may be displaced, for example, along a road at a high speed.
