An automobile towing apparatus for mounting on a tow truck which has a boom consisting of a generally horizontal forward portion (13) connected at its rear end to a portion (14) extending downward, which in turn is connected to a pivoting rear portion (15). The rear portion (15) is extensible and carries a transverse beam (32) at its rearward end, which in turn carries vehicle lifts to engage and lift the wheels (40) of a vehicle (41). The transverse beam (32) has a limited rotation about the longitudinal axis of the boom rear portion (15). The boom forward portion (13) pivots at its front and rear end on horizontal axes (20,25) which may be individually raised and lowered. The pivotal freedom of the transverse beam (32) and the boom allows the loading of vehicles situated on relatively sloping surfaces. The transverse beam (32) also pivots about a generally vertical axis at the rear of the boom rear portion (15) to accommodate misalignment when towing. Brake bars (42) are positioned below beam (32) whilst towing, and engage the ground if the boom rear portion (15) is lowered in emergency. |
