Abstract: Counterweights for elevator systems are described. The counterweights include a frame and a counterweight safety system attached to the frame. The safety system includes a safety brake mounted to an upright of the frame and configured to enable engagement with a guide rail to apply a braking force. A sheave is mounted to the frame and configured to operably connect to tension members. The sheave is configured to move between a first position when under tension and a second position when the tension is lost. A connecting link operably connects the sheave to the safety brake. The connecting link has first and second link members operably connected between the sheave and the safety brake.

Abstract: A travelling cable end hitch and rail arrangement for an elevator system includes a rail assembly fixed to an elevator car of the elevator system, a movable device positioned at and movable along the rail assembly, and an end hitch portion of a travelling cable of the elevator system secured to the movable device and movable with the movable device along the rail assembly. A method of accessing a travelling cable end hitch of an elevator system includes accessing a travelling cable from inside of an elevator car, pulling the travelling cable upward from inside of the elevator car, moving an end hitch portion of the travelling cable along a rail assembly secured to a bottom of the elevator car via pulling the travelling cable upward, and inspecting the end hitch portion from inside the elevator car when the end hitch portion reaches a first end of the rail assembly.

Abstract: A runby monitoring system for an elevator system includes a sensor fixed in a hoistway of the elevator system, and a sensed element located at a moving component of the elevator system. The sensor is configured to detect a presence of the sensed element when the sensed element is substantially aligned with the sensor in the hoistway. The detection of the presence of the sensed element at an expected elevator system operational point is indicative of a clearance between the moving component of the elevator system and a lowermost extent of the hoistway within a preselected range.

Abstract: A guide rail support of an elevator includes a guide rail bracket having a first side, a second side, a first mounting portion, and a second mounting portion. The first mounting portion is attachable to an elevator shaft and the guide rail bracket has inclined apertures in the second mounting portion. An adjustment bracket is configured to contact the second side at the second mounting portion, the adjustment bracket having inclined apertures configured to align with the inclined apertures of the guide rail bracket to define stem apertures. First and second rotating members are installed through the stem apertures. Each rotating member has (i) a rotating head that movably engages with a guide rail, (ii) an integrally formed stem configured to pass through a respective stem aperture, and (iii) a middle defining a length that is greater than a thickness of the guide rail bracket and the adjustment bracket.

Abstract: An elevator car (1) defining an interior space (2) for accommodating passengers and/or cargo. The elevator car (1) includes a working platform (12) moveable between a stowed position, above the interior space (2), and an operational position, suspended within the interior space (2), a hoisting device (18) located at the working platform (12) and a tension member (16a, 16b) connected to the hoisting device (18) and connected to the working platform (12) such that a suspending portion (17a, 17b) of the tension member (16a, 16b) suspends the working platform (12). The hoisting device (18) is configured, when actuated, to alter the length of the suspending portion (17a, 17b), so as to hoist the working platform (12) between the stowed position and the operational position.

Abstract: An elevator system is provided including a hoistway having a plurality of landings. An elevator car is configured to move within the hoistway between the plurality of landings. A plurality of guide rails guide movement of the elevator car and a counterweight within the hoistway. Each guide rail includes a base and a blade. A machine assembly is mounted within the hoistway and includes a traction sheave rotatable about an axis. The traction sheave is configured to drive movement of the elevator car between the plurality of landings. At least one of the plurality of guide rails is arranged in an overlapping configuration with the machine assembly such that a plane defined by the base of the guide rail is parallel to the axis and intersects a portion of the traction sheave.
