Abstract
A machine for supporting and lifting an automotive chassis module into position for assembly with a vehicle body being conveyed overhead along an assembly line includes a mobile vehicle having at least one fixture arranged above the vehicle for receiving and supporting the chassis module, and a guided lift mechanism for moving the fixture vertically between lowered and raised positions. The lift mechanism includes a push chain that is coupled to the fixture and a sprocket that engages the chain and is operative when driven to displace a section of the chain vertically to move the fixture. The lift mechanism further includes at least one support member extending between the fixture and the vehicle which operates to guide the fixture in the vertical direction while isolating the push chain from any loads transverse to the vertical direction.
