发明名称 Hand truck
摘要 A hand truck includes a rectangular main frame having a hand grip attached at the upper end of the main frame and a nose attached at the lower end of the main frame. A secondary rectangular frame lies alongside the back side of the main frame, with the secondary frame being pivotally attached at its upper end to the main frame. A pair of primary wheels are attached to the lower end of the secondary frame for rolling the hand truck over a support surface such as the ground or floor. A pair of auxiliary wheels are provided on a swing away frame. The auxiliary wheels can be moved to a position in which the hand truck rests in a stable position on all four wheels. The main frame can then be pivoted about the pivotal connection to the secondary frame to be positioned in a horizontal or near horizontal position elevated from the ground or floor. Heavy objects such as kegs of beer can be rolled directly from a truck, rack or conveyor to the hand truck without requiring the operator to lift the heavy objects.
