type, completely housed and running in an oil bath, shall satisfy the AGMA
Standards and shall be of sufficient capacity for the use intended. Emergency
operation shall be through auxiliary hand chain extending to a point easily
accessible from the floor. Drive from reducer to door shaft shall be through
