Abstract
Abstract A self-propelled wheeled vehicle has a load receiving tank with the driving wheeled suspension system and the driven steering control system directly attached to the load receiving tank. The prime mover and power transmission system is also attached to the tank and interconnected with the driving wheels. An operators cab is attached to the forward end of the load receiving tank. A front loader mechanism is integrated with a top front load receiving opening in the tank and the closure therefor such that movement of the closure simultaneously lifts an interconnected load container, raises same and dumps the load into the load receiving tank and vice-versa. The chassiless vehicle is applicable to rear loader and side loader use.
