A safety gear arrangement for an elevator system, comprising a safety gear mechanism comprising at least one wedge portion of the safety gear arrangement, wherein, in a normal position, the at least one wedge portion is retracted and, in an operated position, extended by a first spring element for acting on a guide rail of the elevator system, and a triggering device comprising an electromagnet, a second spring element, an actuating member, and an excitation power input, wherein the electromagnet is arranged, while being supplied with excitation power, to maintain the actuating member in an untriggered position against the second spring element, and the actuating member is arranged to operate the safety gear mechanism in response to moving of the member from the untriggered to a triggered position due to the second spring element.

The elevator comprises guide rails extending along a height of a shaft, a car and/or a counterweight moving upwards and downwards in the shaft and being glidingly supported on the guide rails. A stop block is attached to at least one guide rail in order to prevent movement of the car and/or the counterweight beyond the level of the stop block. The stop block comprises a buffer attached to a bottom plate. The buffer comprises a slot receiving a guide portion of the guide rail. The bottom plate supports the buffer on the guide rail.

A counterweight module, a locking element, a counterweight and a method for assembling a counterweight are disclosed. The counterweight module includes a first part and a second part, between which a straight joint is arranged at right angle in relation to the longitudinal direction of the counterweight module. The counterweight locking element can be used to secure the counterweight modules into a counterweight frame. In the method, the counterweight is filled with balancing modules starting from the bottom of the frame.

Elevator counterweight

A sliding guide shoe includes at least a body part, which includes at least a slide pad space for a slide pad as well as at least one fixing part for fixing the sliding guide shoe to its base. The body part is essentially the same in its cross-sectional profile throughout its whole length. An elevator is also provided with the sliding guide shoe.
