Abstract

535,597. Cranes mounted on vehicles. TREDEGAR, E. F. MORGAN, VISCOUNT. (Falcke, D.). May 7, 1940, No. 8226. [Class 78 (iv)] Turntable cranes carried on vehicles are provided with additional ground-engaging supports to the rear of the road wheels of the vehicle. Fig. 2 shows a turntable 16 mounted to overhang the narrowed chassis 10 at the sides and rear. Two pairs of inverted, V-shaped legs 19, 20 fixed to the table are set so that the plane of each pair is radial to the turntable and at about 30 degrees to the longitudinal axis of the vehicle, the two pairs being on opposite sides of the longitudinal axis and being formed as hydraulic cylinders, the rams of which carry pneumatic-tyred castor wheels set tangentially to the turntable. When the pistons are retracted, the castor wheels are clear of the ground, but when extended, each engages the ground independently, thus allowing the apparatus to function on uneven ground. A chain tie 28 completes a triangular leg structure when the pistons are fully extended. The turntable may carry the usual luffing jib mounted on a horizontal axis, or as shown, may be fixed to the turntable and carry a sliding extension 18.
