Retrofit An Elevator To Replace A Manlift
A proposal was made by Humphrey Manlift for Market in retrofitting a 350 lb. elevator assemblies in replacement of aging manlifts. The existing manlift pits will need to be slightly modified to accommodate the elevator assembly.
A 46″ x 37-1/2″ box will need to be cut into the existing area of the pit for this accommodation.
The elevator assembly components must be caged-in at each floor in order to comply with current ANSI (American National Standards Institute) standards. A bolt-together, 4-piece cage was designed to surround the elevator assembly in order to comply with these standards. The framework of the cage is constructed of 2x2 square tubing with bolt-on 12 GA. sheet metal skins. Each frame weldment will bolt together using four 3/8″ bolts at each corner. The front of the cage utilizes the same door as used in the hoistway tower applications.
