An elevator system that includes a pair of tubular guide rails that are positioned forward of the center of gravity of the elevator car. One of the hollow rail members contains electrical wiring for servicing elevator control and indicator circuits while the other rail member slidably contains a counterweight that is attached to the car to reduce the amount of energy required to raise and lower the car. Placing the guide rails so as to favor the front or door side of the car provides for shorter electrical conduit runs and also allows the rails and the stiles of the car frame to be superimposed within the hoistway thereby saving a considerable amount of space. The car frame is also formed of hollow tubular members in which is contained the electrical service to the cab.
