ABSTRACT A portable unloader for a truck bed includes a gate entrained on a pair of cables so that it can be pivoted to and from a first raised position in which it is inclined with respect to the truck bed as it moves toward the rear of the truck bed, and a second position in which it lies substantially parallel to the truck bed as it moves through the load along the truck bed. In one form of the invention, the cables pass through slots near the lower edge of the plate, and the gate is secured near its opposite edge by restraining chains attached to the cable to limit the angle at which the gate is inclined with respect to the truck bed. Such a gate can also include a pair of wedge-shaped runners for initially orienting the gate at a slight angle to the truck bed so that a portion of the load of granular material is forced under the gate to lift it to its raised position as movement toward the rear of the truck is initiated. In another form of the invention, the gate is pivotally secured to a sled which slides along the truck bed. The sled includes upright supports pivotally securing the upper edge of the plate forming the gate above the truck bed. The sled can also include a supplemental pivoting gate secured to the forwardmost end of the sled to traverse the forwardmost portion of the truck bed.
