A method and apparatus for installing a plurality of coated steel belts as tension members for an elevator system. A dispenser is employed that retains a plurality of rolled steel belts aligned vertically in said dispenser. An axel passing through the side walls of the dispenser and the centers of the steel belts rolls contained therein rotatably supports the steel belt rolls. When employing the disclosed method, equal lengths of the belts are pulled from the dispenser and clamped between two metal plates. A guide is then connected to the clamped plates which is used to feed the secured coated steel belts down the elevator shaft, around the sheave mechanism and back up the elevator shelf. The center core of the dispenser allows for the even systematic dispensing of steel belts so that equal lengths of the steel belts are fed simultaneous throughout the elevator system.

An improved method for mounting elevator rails within a hoistway includes the initial step of securing support brackets to a pair of rails. The brackets, rails, a machine for driving a cab and a dead end hitch are then mounted within the hoistway. A cab may then be moved vertically within the hoistway and additional support brackets are placed at vertically spaced locations. The connection of the brackets and rails provides support to dissipate the loads which are transferred into the rail in such systems wherein the machine or the dead end hitch is fixed to a rail. Once the rails have been adequately supported by additional brackets, the brackets which are secured to the rails are removed from the rail. The brackets provide support, but are no longer fixed to the rails.

An elevator system includes a hoistway that extends upwardly from a pit area to an upper hoistway area. A support plate extends across a lateral width of the hoistway and is mounted between a machine base and a guide rail assembly. A hoist tool is mounted within the hoistway near the upper hoistway area for lifting the machine base and rail assembly upwardly through the hoistway from the pit area to the top of the hoistway. The hoist tool supports a first set of pulleys and the support plate supports a second set of pulleys. A cable is threaded through the first and second sets of pulleys and is connected to a hoist machine for lifting the machine base and guide rail assembly to an installation position in the upper hoistway area via the hoist tool and pulley system.
