摘要： The invention relates to an elevator system and also to a method for monitoring the movement an elevator car. In the method a first emergency braking procedure is activated for braking the elevator car at a first deceleration if the speed of the elevator car exceeds the first limit value for permitted speed, and also a second emergency braking procedure is further activated for braking the elevator car at a second deceleration that is greater than the first, if the speed of the elevator car exceeds the second limit value for permitted speed that is greater than the first limit value for permitted speed.

摘要： Stall condition in an elevator is potentially dangerous situation if it causes slack to the ropes of the elevator. In such situation a counterweight or elevator car does not move even if the hoisting machine is still operating. This situation may be prevented by stopping the elevator as early as possible after detecting such stall condition. The detection of the stall condition is based on monitoring the torque generated by the hoisting machine of the elevator. When rapid change in the torque is detected a stall condition is suspected. The elevator may be stopped or an alarm may be launched when the stall condition is suspected.

摘要： In the method and elevator of the invention, which preferably is an elevator without machine room, in which elevator the elevator car is at least partially supported by a set of hoisting ropes. The hoisting ropes comprise one rope or a number of parallel ropes. The elevator has a traction sheave which moves the elevator car by means of the hoisting ropes. The elevator comprises rope portions of hoisting ropes going upwards and downwards from the elevator car, and the rope portions going upwards from the elevator car are under a first rope tension (T1) and the rope portions going downwards from the elevator car are under a second rope tension (T2). The elevator has a compensating device acting on the hoisting ropes to equalize and/or compensate rope tension and/or rope elongation and/or to render the ratio (T1/T2) of the first and the second rope tensions substantially constant. The compensating device comprises an arrangement producing an auxiliary force acting substantially in the same direction with the first rope tension (T1).

摘要： A method for braking a traction sheave elevator stops the elevator in the event of an emergency by the braking of the elevator using a braking device not comprised in the drive machine. A traction sheave elevator is provided with a braking device not comprised in the drive machine and designed to improve the efficiency of emergency stopping. The maximum force decelerating the elevator and generated by the braking device equals about half the weight of the nominal load of the elevator.

摘要： A car speed monitoring assembly for an elevator includes an elongated flexible member tensioned to extend in a hoistway of the elevator in a longitudinal direction of the hoistway and first and second rollers mounted rotatably on an elevator car and tensioned against a lateral side of the elongated flexible member. Each roller may roll along a surface of the lateral side of the elongated flexible member based on the elevator car moving relative to the elongated flexible member. The car speed monitoring assembly may detect respective rotation speeds of the first roller and the second roller, trigger one or more particular actions when one or both of these rotation speeds exceeds a limit speed, and trigger the one or more particular actions based on the respective rotation speeds deviating from each other. The one or more particular actions include causing movement of the elevator car to be stopped.
