Abstract
An adjustable lift dolly apparatus is described for use in repeatedly lifting and transporting objects of different shapes and sizes. A latching mechanism is described which securely latches the dolly in the lifted position and can be easily released by using a foot pedal. A counterbalance is included which prevents the lift dolly from inadvertently moving an object when the lift dolly is in the unlatched position.
