ABSTRACT:
A system for moving a refrigeration device is disclosed and includes a frame for supporting the refrigeration device. At least one pair of stationary casters are removably coupled to the frame. At least one pair of adjustable casters are removably coupled to the frame and are adjustable relative to the frame within a range between an extended position and a retracted position. A positioner provided on at least one of the frame and the adjustable casters establishes a position for the adjustable casters relative to the frame within the range, so that the stationary casters and the adjustable casters are capable of providing a desired degree of stability during movement of the refrigeration device and the stationary casters and the adjustable casters are removable following movement of the refrigeration device.
