Abstract:

A detachable crane or hoist for mounting on the bed of a pickup truck or other vehicle is constructed from tubular members of square cross section. The structure is readily secured to the truck bed and the boom may be extended to selected lengths with guy lines arranged for the length selected. The boom is pivotally mounted on a roller mounted base and is easily erected and dismantled. A post or column is provided to guide the boom during vertical movement and is extendable to provide raised positions for guy lines and for the hoisting cable. A removable stop on the post provides a secure rest for the boom in its collapsed and lowered position. Short anchoring bars horizontally adjustable in sleeves secured to the rearward end of the structure are used for securing the structure to the truck bed. These bars may be replaced by long bars fitting the same sleeves and also sleeves in the forward end of the structure. The long bars are effective for facilitating removal of the crane from the truck.
