ABSTRACT:
A manual powered hoist and ramp system for pickup trucks enables a single person to lift heavy objects located on handtrucks or dollies onto the loading platform of the truck. The truck tailgate has a pivoted flap extension to form a ramp inclined from the truck loading platform to the ground when pivoted into its opened ramp position with the flap extended. An accompanying hoist has a counterforce mechanism mounted on a pair of elevated stanchion posts on opposite sides of the truck loading platform for producing an upward assisting lifting force establishing tension in a line extending to the ground for attachment to a handtruck or dolly. That force directed substantially parallel to the ramp tending to move the load up the ramp thus enables a single person to handle a heavier load, such as a refrigerator, for hoisting onto the truck platform. The hoist is manually powered and thus stores a force in the counterforce mechanism as the line is extended to ground level to attach to a loaded hand truck or the like. The counterforce mechanism relies upon the weight of lead masses or the like to provide enough lifting force that a single person can manipulate safely larger loads between ground level and the truck platform. The hoist-ramp assembly stores on a pickup truck to convert it to a one person moving vehicle capable of moving large, heavy furniture pieces such as refrigerators.
