  • Patent number: 5017080
    Abstract: A hand truck for lifting and transporting objects. The truck includes an elongated frame attached to a wheel assembly. A carriage is mounted on the frame to travel the length of the frame. The carriage includes a load bed that extends across the frame, and at least one protrusion located below the load bed that extends above the load bed. A seizing arm is pivotally attached to the carriage above the load body and has a seizing arm with a grip point directed toward the load body. The seizing arm has a stem that extends beyond the pivot point attachment opposite the seizing arm body. A winch with cable are attached to the top of the frame. The free end of the cable is attached to the seizing arm stem. Retracting the cable causes the seizing arm to pivot so the grip point is forced against as object located on the carriage. The force of the seizing arm is sufficient to secure the object between the grip point and the carriage.
