ABSTRACT:
A roll bar and crane device for use with vehicles such as a truck is adapted to be mounted to the truck bed. The device includes left and right leg members and a central beam extending therebetween and being selectively detachable thereto. A U-shaped boom extends over the left and right leg members when used as a roll bar. The boom, at one end, is pivotally connected to a pivot member about a horizontal axis of rotation and the pivot member is pivotally connected to one of the leg members and is pivotable about a vertical axis of rotation. A rope and pulley system is provided between the pivot member and the boom. A rope extends from the boom lift end to the pulley and rope system and to a winch that is located on and is rotatable with the pivot member. By pulling the rope via the winch, objects attached to the end of the rope are drawn up and to the boom lift end and the boom is also caused to pivot about the horizontal axis of rotation for lifting the boom lift end.
