20090120733 | ARRANGEMENT IN AN ELEVATOR WITHOUT COUNTERWEIGHT - The present invention relates to an arrangement in an elevator without counterweight, which comprises at least a control unit ( | 05-14-2009 |
20090183955 | RETRACTABLE STOP FOR MAINTAINING OVERHEAD CLEARANCE ABOVE AN ELEVATOR CAR - An assembly ( | 07-23-2009 |
20110240415 | Modular Weighting Elements - The invention relates to a modular weighting element ( | 10-06-2011 |
20120067674 | ELEVATOR WITH AN ELEVATOR CAGE AND A COUNTERWEIGHT - An elevator cage is arranged in an elevator shaft at one end of a support means, and a counterweight is arranged at the other end of the support means. If the elevator cage is at the top in the elevator shaft, the support means length and the weight of the support means are large on the counterweight side. If the elevator cage is at the bottom in the elevator shaft, the support means length and the weight of the support means are large on the cage side. A first balancing element and a second balancing element are provided as equalization for the weight shift from the counterweight side to the cage side. | 03-22-2012 |
20120152663 | ACTIVATING A SAFETY GEAR - In this elevator system, a traveling body has arranged upon it a safety gear for braking and holding the traveling body tight on the guiderail, or on a braking rail. The safety gear is connected to a device for actuating the safety gear, which can also actuate the safety gear. The device for actuating the safety gear contains a coupler body, which can be pressed against the elevator hoistway, possibly against the guiderail or braking rail, wherein actuation of the safety gear is effected by a relative movement between the pressed-on coupler body and the safety gear. For this purpose, the coupler body can contain a curved coupler surface, which, in case of need, is brought into engagement with the elevator hoistway, or with the guiderail or braking rail. | 06-21-2012 |
20130180804 | GRAVITY COMPENSATION DEVICE AND LIFT APPARATUS INCLUDING THE SAME - A link has first and second ends coupled, so as to be axially shiftable, respectively to two shafts that include a reference point located in a base and cross each other. A gas actuator has an inner space that has gas pressure pressing the first end of the link toward the reference point so as to shift the first end of the link such that a distance between a first end position of the link and the reference point is equal to or more than a distance between the first and second ends in a state where the inner space has a volume equal to zero obtained by extrapolating variation of the inner space volume relative to the first end position. The second end and a lift section that is vertically shiftable with respect to the base are coupled by means of a coupling section. | 07-18-2013 |
20140284148 | COUNTERWEIGHT ARRANGEMENT FOR AN ELEVATOR AND AN ELEVATOR - A counterweight arrangement for an elevator, includes a first vertical guide rail and a second vertical guide rail, the guide rails defining a vertical guide rail plane, a counterweight arranged to travel between the guide rails guided by the guide rails, the counterweight including a frame, which includes a first upright beam and a second upright beam and a cross beam connecting the upper ends of the upright beams, and a diverting pulley mounted between the guide rails on the cross beam of the counterweight frame, the pulley having a vertical plane of rotation, which crosses the guide rail plane. The cross beam is aligned parallel with the plane of rotation of the pulley. An elevator includes the aforementioned counterweight arrangement. | 09-25-2014 |
20150291396 | ELEVATOR COUNTERWEIGHT DEVICE - In an elevator counterweight device, a frame body includes a first stile, a second stile, a crosshead provided between upper portions of the stiles, and a plank provided between lower portions of the stiles. On both sides of the frame body in a width direction thereof, a plurality of guide devices are provided. Each of the crosshead and the plank is coupled to the first stile and the second stile so as to be pivotable. Each of the guide devices is displaceable in the width direction of the frame body and a thickness direction of the frame body relative to the frame body, and is pivotable about an axis parallel to a vertical direction of the frame body as a center. | 10-15-2015 |

20140332325 | FILLER PIECE FOR AN ELEVATOR COUNTER-WEIGHT - Each filler piece ( | 11-13-2014 |
20150114765 | INSPECTION TESTS FOR AN ELEVATOR WITHOUT ADDITIONAL TEST WEIGHTS - The invention allows inspection tests for an elevator without additional test weights. An empty elevator car and its counterweight are balanced by filling in weight pieces to the counterweight. 100% load of the elevator car in regard to unbalance is configured by moving unused counterweight pieces inside the elevator car. Inspection tests requiring the 100% load in regard to unbalance are performed. 125% load of the elevator car is simulated with 50% load and 125% speed of the elevator car. Inspection tests requiring the 125% load in regard to unbalance are performed. A final counterweight is configured by moving its weight pieces from the elevator car to the counterweight. Inspection tests requiring the final counterweight are performed. | 04-30-2015 |
