Abstract

This machine comprises a chassis which bears at one end a motor unit for driving large size drive wheels whereby said chassis rests on the ground at this end. At its other end, the chassis is provided with retractable supports by which it may rest on the ground. This end also carries a turret mounted on the chassis by an orientation ring and supporting the cabin. A working assembly is articulated on this turret immediately above the orientation ring in such a way as to be subjected to vertical clearance swinging movement by passing beside the cabin. Arms associated with jacks and supporting steering wheels are also articulated on this cabin. When the cabin is facing forward, the cabin and motor unit are disposed on one side of the longitudinal axis of the machine, while the working assembly is disposed on the other side of that longitudinal axis.
