A method for forming a guide structure in an elevator shaft provides a guide structure configured to guide an elevator car during vertical travel in the elevator shaft. The method includes the following steps: moving a tool, such as a milling tool, vertically along the elevator shaft, wherein the tool is precisely positioned with respect to the horizontal position thereof within the elevator shaft, and forming the guide structure by removing material on a shaft wall of the elevator shaft using the tool.

An underground mine hoist and method of operating the mine hoist is provided. Unlike conventional underground mine hoists, the hoist may be operated at a production rate less than the designed maximum production rate at least part of the time to improve the life of the hoist and efficiency of operation. In order to vary the hoist production rate, an input rate and/or output rate of mined material is monitored, and the hoist production rate is varied based on such monitoring.

According to an example embodiment, an apparatus for controlling at least one aspect of operation of an elevator car door via operating a door driving system arranged to drive movement of the car door between first and second end positions of its movement range, wherein the door driving system comprises an electric motor that is coupled to the car door via a transmission system and wherein, the elevator car comprises a door coupler connected to the car door for temporarily coupling the car door to a landing door when the elevator car resides in a landing zone of a landing such that the landing door moves between a closed position and an open position together with the car door is provided, the apparatus configured to: control movement of the car door, monitor one or more parameters that are descriptive of power consumption of said electric motor upon movement of the car door, and carry out a configuration procedure comprising: recording a first power consumption profile that is descriptive of the power consumption of said electric motor as a function of the car door position when the car door is moved from the first end position to the second end position, recording a second power consumption profile that is descriptive of the power consumption of said electric motor as a function of the car door position when the car door is moved from the second end position to the first end position, and designating one of the first and second end positions as a closed door position and the other one of the first and second end positions as an open door position based on one or more characteristics of the first and second power consumption profiles.

An elevator shaft element, an elevator arrangement and a method. The elevator shaft element comprises a frame module arranged for receiving an elevator car therein. The frame module is constructed from a transport and/or storage unit, comprising side walls, a bottom wall and a roof wall. The unit is arranged to be positioned vertically such that said side walls, bottom wall and upper wall of the unit define an inner space of the elevator shaft. Elevator car guides for guiding movement of the elevator car in the elevator shaft element are attached to said bottom wall and/or roof wall.

An elevator system (2) comprising a hoistway (4), an elevator car (6) and a counterweight (8) arranged to move within the hoistway (4). The system (2) further includes a first counterweight guide rail and a second counterweight guide rail arranged to guide the counterweight within the hoistway (4) and a guide rail bracket (32) which connects the first and second counterweight guide rails together. An elevator machine (10) is arranged to drive a tension member (14), which couples the elevator car (6) and counterweight together (8), to move the elevator car (6) within the hoistway (4). The system (2) further includes a friction reducing element (36) arranged on the guide rail bracket (32) such that if the tension member (14) moves towards the guide rail bracket (32) during operation of the elevator system (2), the tension member (14) contacts the friction reducing element (36).

A rail installation assist device includes at least control circuitry. The control circuitry is configured to acquire displacement information representing displacement of individual rail brackets and a rail joint from a reference position, the rail brackets that fix guide rails in an elevator shaft, the rail joint that joins the guide rails together; estimate, from the displacement information, a change in the displacement information of the rail brackets and the rail joint when the rail brackets are moved to given target positions; calculate an evaluation value for variation in the displacement information before the change and an evaluation value for variation in the displacement information after the change; and set positions of the rail brackets based on a result of comparison between the evaluation values.

The present disclosure is related to a travelling cable clamp assembly fixing an elevator travelling cable to a fixing base, such as to a first movable support structure in the hoistway for supporting said at least one elevator unit movable in the hoistway, including at least an elevator car.
