Abstract: The invention is a kit for attaching to a truck cap to enable the cap to be lifted off of and lowered onto a truck by lines from above. The kit includes: a first rail and a second rail, each configured to attach to the truck cap; a first pair of sliding masts for releasably attaching to the first rail and a second pair of sliding masts for releasably attaching to the second rail. Each of the sliding mast includes: a sled which is captured by the rail, and is slidable along the rail, and is adapted to be secured at various points along the rail; and a brace with one end attached to the sled and the other end adapted to receive one of the lines. In another aspect, the kit includes multiple lifting devices.

Abstract: An apparatus for lowering a hitch onto a truck bed and raising the hitch off of a truck bed is disclosed. The apparatus includes: an upper carriage, a lower carriage, and a kingpin. The upper carriage is suspended from multiple lines, which lines are configured to lower and raise the upper carriage. The lower carriage is attachable to the upper carriage at various positions relative to the upper carriage to allow the load on the lines to be balanced in one direction. The kingpin is attached to the lower carriage, and kingpin is configured to be captured by the hitch. Allowing the hitch to be lowered onto the truck bed and raised off of the truck bed as the upper carriage and the lower carriage are lowered and raised by the lines. Another embodiment of the apparatus includes lifting devices attached to the lines for raising and lowering the hitch.
