ABSTRACT:
A straddle carrier for heavy loads of the type which is driven over a load so that the load is generally beneath the carrier and straddled by the wheels of the carrier. The carrier includes a main frame which has a gripping tong mechanism integrally mounted thereon for clamping the load. The entire main frame and tong assembly may be raised and lowered to permit handling the load by means of cylinder/strut arrangements at each of the four wheels. A linkage comprising extensions from the wheel carrying members and a steering cross bar associated with each of the front and rear pairs of wheels is hydraulically activated independently of the main frame to permit steering the vehicle from any elevation. Mounted on the main frame, and like the main frame lowered and raised relative to the wheels, are an operator's cab and a motor and pump housing for driving the straddle carrier and actuating the various hydraulic cylinders of the carrier.
