ABSTRACT:
This invention relates to improved dollies for lifting and moving heavy objects such as furniture, refrigerators, and the like. It comprises a base plate having four casters with a top plate mounted thereabove. The top plate can be elevated via a pedal-actuated lever and link mechanisms to raise the load off the floor for movements and then lower it down. The invention includes a telescopic mechanism for adjusting the top plate with respect to the base plate and a spring to bear the main weight of the load to be moved. The lifting lever can be folded out of the way for load movement where clearance is a problem.
