Abstract

A pivotable hand truck for supporting or installing a heavy object is provided comprising an L-shaped structure, a pair of wheels secured to the L-shaped structure about which the structure may be pivoted between horizontal and vertical positions, and lifting means carried by the structure adapted to vertically adjust the object to a selected height above the floor surface. The lifting means is defined by a floor-engaging pedal affixed to the L-shaped structure, height-adjusting members carried by the structure, and activating means for activating the height-adjusting members when the pedal is moved between a non-operational position and an operational position. The activating means is defined by a rod member secured to the apparatus which engages the height-adjusting members, and coupling means mechanically coupling the rod member to the pedal. The coupling means is defined by a plurality of interconnecting lever arms, or, alternatively, a cable-and-pulley mechanism. In use, the operator depresses the floor-engaging fulcrum elevating one end of the structure. The depressing of the pedal activates the activating means which, in turn, activates the height-adjusting members which, in turn, engage the floor surface and elevate the opposite end of the structure, thereby variably elevating the object as desired.
