A load-unloading subassembly for use with a wheeled handtruck characterized by a pivotal and slidable connection between the sideframe elements of the load-unloading frame and the corresponding upright elements of the handtruck frame which connections cooperate with a scissor link pivotally interconnecting the two to cause a push-off shoe at the lower end of the load-unloading subframe to move substantially horizontally across the load-carrying platform of the handtruck to separate a load therefrom when the subassembly frame is rotated.

The combination of a handtruck and a load reacting subassembly, said handtruck having a frame which includes a pair of transversely spaced uprights supporting at the lower end thereof a load-carrying platform and having a pair of wheels connected by an axle and attached to the frame, said load reacting subassembly comprising: a pair of sideframe elements, each sideframe element having upper and lower ends and handle means interconnecting the upper ends of each element; elongated straight track means carried by the uprights of the handtruck frame; track follower means slidably carried by the track means; means pivotally interconnecting the sideframe elements to the track follower means, at a point intermediate the upper and lower ends of the sideframe elements; a shoe carried by and interconnecting the lower ends of the sideframe elements; a pair of rigid straps each having first and second ends; a pivotal interconnection between each of the said first strap ends and the respective uprights where the point of interconnection is in longitudinal alignment with the track means and intermediate the position of the track follower means and the plane of the load-carrying platform; a pivotal interconnection between each of the said second strap ends and the respective sideframe elements where the point of interconnection is intermediate the point of interconnection between the sideframe elements and the track follower means and the point of interconnection between the sideframe elements and the shoe.
