ABSTRACT:
A pair of wheel assemblies (26, 28) are vertically spaced apart and are supported for rotation about parallel axis (30, 38) by a common support frame (10). Each wheel assembly (26, 28) comprises a pair of wheels at its ends (38, 40). The wheels (34, 40) have radially outwardly opening channel portions (80) in which traveling bearing pads (64, 66) are received. The bearing pads are secured to endless support cables (46), and also to the end portions (152) of carrier beams (150, 194) which extend between the two wheels (34 or 40) of each assembly (26, 28). The carrier beam (150, 194) is an upper portion of a carrier (48, 48', 176) onto which is placed a motor vehicle or some article which is to be stored. A first drive cable section (54) is connected to the support cable (46) and extends therefrom to a winch drum (50). A second drive cable section (58) extends from the support cable (46) in the opposite direction to the same winch drum (50). When the winch drum (50) is rotated in one direction, it pulls on one of the drive cable sections (54, 58), and the second drive cable section (54, 58) is unwound from the winch drum (50). When the direction of rotation of the winch drum (50) is reversed, the first drive cable section (54, 58) is paid off of the winch drum (50) and the second drive cable section (54, 58) is wrapped onto the winch drum (50).
