A machine for supporting and lifting an automotive chassis module into position for assembly with an automobile body 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 helical push actuator having a drive motor and at least one band that can be advanced and retracted in a vertical helix with an end of the band being coupled to the fixture to move the fixture between the lowered and raised positions by helical advancement of the band under control of the motor. The lift mechanism includes spaced support members that each extend between the fixture and the vehicle to guide the fixture in the vertical direction and restrain the fixture from moving horizontally.
