    Abstract: In the invention a method is presented for ensuring operating safety in an elevator system, an elevator system, and a safety device of an elevator system. The elevator system comprises at least an elevator car, elevator ropes, an elevator motor, a traction sheave and at least two holding brakes, which holding brakes are arranged to prevent movement of the elevator car when the elevator is stopped. According to the invention the first holding brake is engaged at the end of an elevator run, and the other holding brakes are engaged with a delay. When one holding brake is engaged, the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, a procedure for preventing a hazardous situation is performed.

    Abstract translation: 在本发明中提出了一种用于确保电梯系统，电梯系统和电梯系统的安全装置的操作安全性的方法。 该电梯系统至少包括电梯轿厢，电梯绳索，电梯马达，牵引滑轮和至少两个保持制动器，该保持制动器被布置成当电梯停止时防止电梯轿厢的移动。 根据本发明，第一保持制动器在电梯运行结束时接合，并且其他保持制动器延迟接合。 当一个保持制动器被接合时，电梯的运动状态和制动器的任何滑动都被监测。 如果检测到制动器打滑，则执行防止危险情况的程序。

    Abstract: In the invention a method is presented for ensuring operating safety in an elevator system, an elevator system, and a safety device of an elevator system. The elevator system comprises at least an elevator car, elevator ropes, an elevator motor, a traction sheave and at least two holding brakes, which holding brakes are arranged to prevent movement of the elevator car when the elevator is stopped. According to the invention the first holding brake (106,107) is engaged after elevator run has ended, and the other holding brakes (106,107) are engaged with a delay. When one holding brake is engaged when the elevator is stopped and empty, motor torque is increased to a certain limit and the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, the torque at which slipping starts is registered and a procedure for preventing a hazardous situation is performed.

    Abstract: PCT No. PCT/FI95/00646 Sec. 371 Date Jul. 24, 1997 Sec. 102(e) Date Jul. 24, 1997 PCT Filed Nov. 22, 1995 PCT Pub. No. WO96/16892 PCT Pub. Date Jun. 6, 1996A reserve power system includes a reserve power machine (2) for the generation of power. The reserve power machine (2) is connected via a distribution network (4) to consumers (10,12) and elevator drives (8). The elevator drives include an elevator hoisting motor (28) and a frequency converter (26) controlling it. The elevator drives are provided with regulating devices (26, 44, 46) by means of which the speed of the elevator motor (28) is so adjusted that the power taken by the elevator drive (8) from the distribution network (4) is lower than an adjustable power limit (PA).
