发明名称 Two wheel hand truck
摘要 A two wheel hand or appliance truck of the type used for moving heavy objects obtains extra lifting leverage through the use of a separate, pivotally-attached handle which is connected to the pre-existing conventional handle forming a part of the frame. The secondary handle is attached securely to the main frame of the truck by means of welded braces near the top of the primary handle, and may be pivoted upwardly into an operating position against the tension of a shock cord assembly. The secondary handle permits additional leverage to be applied to the load to be lifted.
