Abstract: Embodiments are directed to obtaining an elevator with low overhead space and low pit space by positioning a car of the elevator to have a space from a vertical wall of a hoist-way, mounting a governor in the space between the car and the wall, and mounting a sheave to the car, wherein the sheave is positioned in a projection of the car to the wall.

Abstract: A device for stopping an elevator car travelling up or down along guiderails installed in a hoistway includes a chassis mounted on a side of the car, and an overspeed governor, a guiding device and safety gear mounted on the chassis. The overspeed governor detects when a car overspeed is occurring. The guiding device guides the elevator car along a guiderail. The safety gear is vertically aligned with the guiding device on the chassis and stops the elevator car by frictionally engaging the elevator guiderail, which passes through a channel formed in each of the safety gear and the guiding device. The safety gear causes the elevator car to stop by frictionally engaging the guiderail when the overspeed governor detects a car overspeed is occurring.
