ABSTRACT:
A patient movement system comprises a rotatable section coupled to a frame that moves in a horizontal plane. A hoist assembly is coupled to the rotatable section and spins relative to the rotatable section. The hoist assembly may be positioned by the rotatable section. The hoist assembly includes a first motor coupled to a first linearly moving pulley by a first linkage. The first linkage includes horizontal and vertical sections of travel, whereby the vertical sections of travel decrease when the horizontal sections of travel increase. The hoist assembly includes a second motor coupled to a second linearly moving pulley by a second linkage. The second linkage includes horizontal and vertical sections of travel, whereby the vertical sections of travel are decrease when the horizontal sections of travel increase. The hoist assembly may include additional pulleys to guides the first and second linkages.
