ABSTRACT:
The invention pertains to a lightweight portable lifting device with an adjustable handle which is leveraged to tighten against a lifting bar at an easily adjustable variable distance from a support surface and is usable in pairs to lift and move objects, such as furniture. The handle and lifting bar have interlocking engagement teeth which are quickly and easily disengageable to permit positioning the handle member at a multiplicity of locations along the lifting bar. In a preferred embodiment, the handle is engageable and disengageable from the lifting bar simply by pivoting the handle between the lifting and a release position.
