ABSTRACT:
A vehicle-mounted load hoisting device includes a pivot frame mounted on the vehicle for pivotal motion about a first horizontal axis extending transversely to the vehicle length; a cantilever arm connected to the pivot frame for pivotal motion about a second horizontal axis extending parallel to the first axis; a pivot arm articulated to the cantilever arm for pivotal motion about a third axis oriented parallel to the first and second axes; a pulley mounted at an end of the pivot arm for supporting a cable or the like wound on a winch and attachable to the load; and an arrangement for locking the cantilever arm and the pivot frame together to form a rigid unit pivotal about the first axis. When forming the rigid unit, the cantilever arm is in contact with a stop face on the pivot frame and extends as a longitudinally aligned continuation of the cantilever arm.
