An elevator door system for an entrance opening to an elevator cab. The system includes a two-part door having an open position and a closed position. The two-part door includes a first door portion for traversing across and covering a portion of the entrance opening as the two-part door moves between the open position and the closed position of the two-part door. The two-part door also includes a second door portion for traversing across and covering another portion of the entrance opening as the two-part door moves between the open position and the closed position of the two-part door. A header track includes a rail with a door track for guiding movement of the first and the second door portions. The door track is held onto the rail of the header track via an S-shaped spring clip.

Door track for an elevator door system

An apparatus or tool for installing an elevator hoist machine to a support at the top of the vertically extending guide rails. The apparatus includes a carriage for imparting vertical movement to move the hoist machine to the upper end of the guide rails and then horizontal movement thereto at the upper ends of the guide rails to enable hoist machines to be installed in areas with limited ceiling height.

Elevator hoist machine installation apparatus

A safety plank assembly for mounting on a bottom of an elevator car in a traction-type elevator system includes a pair of parallel extending plank beams connected by a cross support member. A rope sheave is rotatably mounted at each of opposed ends of the plank beams to define a diagonal rope path through the assembly for underslung support of the elevator car. Traction weights and balancing weights can be attached to the beams and provision is made for mounting safety equipment.
