Abstract
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.
