A control unit is used to perform a method for installing an elevator system including the steps of: using an at least partially installed traveling body as a movable working platform borne by traction means and having an electronic safety brake; creating an operating state of the safety brake using the control unit to control the safety brake, the control unit having an input from a safety sensor, a processing unit and a signal output connected to the safety brake; generating a control signal by the processing unit at the signal output, wherein the control signal controls the safety brake; detecting an unsafe operating state by the safety sensor; controlling the signal output due to a detection of an unsafe operating state by the processing unit so that the safety brake is triggered; and removing the control unit when the installation of the elevator system is complete.

Arrangement in an elevator for stopping uncontrolled movement of an elevator car, which elevator comprises at least an elevator car (1) arranged to move reciprocally in the elevator hoistway along guide rails (1a), and means for stopping uncontrolled movement of the elevator car (1). The arrangement according to the invention comprises an arrester (4, 5) separate from the guide rails (1a) of the elevator car (1) and independent of the suspension of the elevator car (1).

A tension member for an elevator system includes one or more tension elements extending along a length of the tension member, and one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member. The one or more wave guide regions are configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions.

An elevator counterweight assembly (11) includes a counterweight structure (38), at least one safety brake (12a, 12b) mounted on the counterweight structure (38), and a safety actuation mechanism (16) including a connection (17) for a suspension member (18). The safety actuation mechanism (16) is configured to move, relative to the counterweight structure (38), between a normal position, and a safety position. In the safety position the safety actuation mechanism (16) is arranged to actuate the at least one safety brake (12a, 12b) and thereby brake the counterweight structure (38). The counterweight assembly (11) also includes a mechanical actuator (22), configured, when actuated, to apply a force to the safety actuation mechanism (16) and thereby move the safety actuation mechanism (16) from the normal position to the safety position, e.g. for the purposes of a handover test.

Provided is a control device for an elevator including: a first control unit configured to control a hoisting machine configured to raise and lower a car and a counterweight in a hoistway; and a second control unit configured to obtain a generation torque which is a torque to be generated by the hoisting machine, and to limit the obtained generation torque to be generated by the hoisting machine so that the obtained generation torque is lower than an abnormal torque which is the generation torque generated when, under a state in which a movement of one of elevating bodies which are the car and the counterweight is limited, the other elevating body is wound by the hoisting machine.

An installation gauge for use in an elevator hoistway is provided. The installation gauge includes a platform assembly and a frame assembly configured to support the platform assembly. The frame assembly includes one or more safety assemblies and one or more guide assemblies. Opposing guide shoes are connected to each of the one or more guide assemblies. The opposing guide shoes are centered about a guide rail and configured to determine a centerline of the guide rail. A lift assembly is configured to facilitate hoisting of the platform assembly and the frame assembly within the elevator hoistway. A plurality of safety ropes couples the lift assembly to the one or more safety assemblies. A climbing rope is attached to the lift assembly. The determination of the centerline of the guide rail can be used as a basis to install other hoistway equipment.

A single-cable drum-type conveying installation with a cable drum driven by a winch drive, includes a cable-monitoring device, a conveying device, which hangs freely on a conveying cable, and an intermediate harness connecting the conveying cable to the conveying device. The cable-monitoring device includes a load-measuring pin, as a constituent part of the intermediate harness, and also a transmission path along which a measuring signal received from the load-measuring pin is transmitted to an evaluation device. The evaluation device is designed for evaluating the measuring signal such that, in the case of the measuring signal jumping by an extent which exceeds a certain amount, a malfunction is detected.
