摘要

Towing apparatus mounted on the rear of a towing vehicle for lifting and towing a disabled vehicle by its wheels has a lifting boom housing for telescopically carrying an extendible boom on which wheel engaging forks are supported. The lifting boom housing disposition is controlled by two hydraulic cylinders. One cylinder is fixed at one end and pivotably connected to the lifting boom housing at the other end which is also attached to and constrained by slidable guide members mounted in slideways for movement in an inclined linear path downwardly and rearwardly relative to the towing vehicle. The other cylinder is pivotably connected to the boom housing and to the guide members for controlling the attitude of the boom housing relative to the roadway. Additionally the wheel engaging forks have a tubular square cross sectional configuration telescopically mountable on a tow bar having a similar configuration so that the forks may be disengaged from the tow bar and disposed at 90 DEG or 180 DEG dispositions from the operative position. The tow bar is mounted for rotational movement about a vertical axis and may also be mounted about a horizontal axis extending axially relative to the boom housing.
