摘要： An apparatus for removing and installing a truck cap, the apparatus is formed by a box member having an opening, the box member being adapted at one end to a truck hitch and the other to a sleeve. A mast is rotatably disposed in the sleeve. A boom having a first end and a second end is fixedly attached at a right angle at the first end to the mast. A first slideable member is slideably coupled to the boom at the second end of the boom. A spread arm is fixedly attached at a right angle to the first slideable member. At least two bumpers are disposed on the spread arm and one bumper on the boom. In use, the rod of a jack disposed within the box member engages the mast through the opening of the box member to raise or lower the mast.
