Abstract: A material handling device may be configured to move and deliver a variety of materials throughout a worksite. The material handling device may be configured to be supported on a variety of vehicle platforms. Once the material handling device has been transported, the materials may be dumped from the material handling device. The dumping process may be initiated through the use of an actuator. The material handling device may comprise a dump body and a base frame. The dump body may be configured to be hingedly attached to the base frame. The base frame may comprise at least one first tube and at least one second tube. Both the first tube and the second tube may be configured to receive a fork and/or any other suitable support structure from a vehicle. The material handling device may comprise an actuator, a pump, and a reservoir which may be positioned within an actuator system area.

Abstract: A chuck for use in screwing one threaded member into another threaded member has a housing with a polygonal socket on one end for receiving a polygonal drive head of a wrench. The housing has a conical bore converging from the face toward the socket. A plurality of retainers are releasably mounted in the bore in a circular array. Each retainer has edges on opposite sides that are spaced apart from the edges of the adjacent retainers to define a receptacle between each of the retainers. A plurality of blades are releasably inserted into the receptacles. Each blade has a gripping edge that protrudes inward from the receptacle, defining with the gripping edges of the other blades a conical space that converges toward the socket for gripping one of the threaded members.
