Hand Trucks And Barrows Patents (Class 298/2)
  • Patent number: 4070060
    Abstract: A manually operated dump truck is provided with front wheels which are located and mounted on the bottom of the truck, as for example, on swivels, so that they are selectively movable from a forward position substantially in advance of the center of gravity of the truck, which is the position selected when the truck is being loaded or used as a conveyance, to a position more closely adjacent the center of gravity when the truck is to be dumped thus reducing the amount of energy required to tip the truck forwardly in a dumping action. Manually controlled latching means is provided to maintain the wheels in the forward position.
