Abstract
Mounting apparatus for a traction machine disposed in a hoistway includes a pair of beams that extend through the hoistway to the pit. One of the beams includes a mounting plate disposed at the top of the beam and to which the machine is fastened. The elevator car frame is engaged with guide rails that are functionally separate from the beams. In a particular embodiment, the guide rails are retained to the beams by clips. The clips retain and position the guide rail without subjecting the guide rails to the load of the traction machine.
