Abstract

An assembly for a pneumatic elevator is provided. The assembly includes a top cylinder housed at a top surface of a vertically stacked elevator cylinder; a control panel box is mounted to a chamber unit, wherein the chamber unit is inbuilt with a split top plate assembly, wherein the chamber unit is operatively coupled to an outer surface of the top cylinder toward a supporting wall. The split top plate assembly includes a split top plate coupled to a top portion of the elevator cylinder. The split top plate assembly also includes a plurality of support tube operatively coupled to an upper surface of the split top plate. The split top plate assembly also includes an air chamber is operatively coupled to a vacuum chamber, wherein the air chamber is configured for air flow between the vacuum chamber and the air chamber.

Claims (23)

1. An assembly 10 for a pneumatic elevator, wherein assembly 10 comprises:
