Abstract: A counterweight assembly for an elevator system includes a counterweight and a guide shoe affixed to the counterweight, the guide shoe extending continuously and unbroken along a vertical length of the counterweight. A counterweight guide system for an elevator system includes a plurality of first counterweight guide brackets secured in a hoistway at a first side of a counterweight and interactive with a first guide shoe affixed to the counterweight. A plurality of second counterweight guide brackets are secured in the hoistway at a second side of the counterweight opposite the first side and interactive with a second guide shoe affixed to the counterweight. Two or more first counterweight guide brackets are engaged with the first guide shoe during travel of the counterweight along the hoistway.

Abstract: An elevator system includes a hoistway and an elevator car suspended in the hoistway via a suspension member and drivable along the hoistway. The elevator car includes an elevator car panel and a battery pocket positioned in the elevator car panel. A battery is removably positioned in the battery pocket. The battery and the battery pocket are configured such that inspection, maintenance and/or repair of the battery is performed without entry into the hoistway of the elevator system. A method of servicing an elevator system includes driving an elevator car along a hoistway and stopping the elevator car near a selected elevator landing floor. A battery is at least partially removed from a battery pocket at the elevator car via a technician located at the selected elevator landing floor for inspection, maintenance, replacement and/or repair.

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 device for limiting sway in a travelling cable (6) in an elevator system is provided. The device comprises: a channel extending in a first direction for receiving the travelling cable (6) therein, wherein the channel is configured to be mounted in an elevator hoistway (2) such that the first direction corresponds to a direction of motion of an elevator car (4) within the hoistway (2); and an element (20) configured to move in the first direction along an open side of the channel simultaneously with an elevator car (4) and to push the travelling cable (6) into the channel when the element (20) moves along the open side thereof.

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.
