Abstract:
An adjustable lift dolly for lifting and moving objects of different sizes comprising:an adjustable first frame having an apex, a rear support assembly with an adjustable length, a plurality of first pivot ends connectable to the object, and a first pair of castors extending downwardly from the adjustable first frame; an adjustable second frame having a center support assembly with an adjustable length, a U-bolt support assembly having an adjustable length, a plurality of second pivot ends connectable to the object, and a second pair of castors extending downwardly from the second frame; a latching mechanism for releasably securing the adjustable first frame to the adjustable second frame, having a footplate attached to said first frame, the adjustable first frame being connectable to the adjustable second frame such that when a downward force is exerted on the apex of the adjustable first frame, the adjustable first frame pivots relative to the first pair of castors thus moving the first pivot ends of the adjustable first frame in an upward direction, said downward force on the adjustable first frame causing the adjustable first frame to exert a downward force on the center support assembly of the second frame, thus causing the second frame to pivot relative to the second pair of castors, thus moving the second pivot ends of the adjustable second frame in an upward direction, the upward movement of the of the first and second pivot ends thereby lever-lifting the object; and a foot pedal attached to the latching mechanism, the foot pedal being functionally associated with the latching mechanism such that by depressing the foot pedal, the latching mechanism disconnects the first frame from the second frame, wherein at least one of the lengths of the rear support assembly, center support assembly, or U-bolt support assembly is varied to accommodate objects of different sizes.
