A collapsible, portable hoist that can be assembled and operated by a single individual, for lifting and conveying heavy objects onto and off of trucks, especially pickup trucks. When not in use, the hoist collapses down to a flat storage configuration that rests on, and is secured to, the truck's cargo walls without any portion extending beyond the truck. In order to deploy the hoist, one rotates its support frame up from the stowed position and then suspends from it the rail along which a trolley or other implement used to convey the object will travel. When the hoist is fully deployed, the trolley rail is mounted high above the bed, permitting tall objects to be manipulated. The hoist is constructed so as to be readily removable from the truck.
