A method for forming and smoothing a hollow-profile guide rail of an elevator system uses a smoothing apparatus to smooth mutually opposing surfaces on a hollow-profile guide rail. The smoothing apparatus includes a guide device, a removal device and a pressing device. The guide device has rollers for moving in a low-friction manner in a longitudinal direction along a first of the opposing surfaces and to thus guide the smoothing apparatus along the first surface. The pressing device has spring elements to press the removal device away from the guide device and toward a second of the opposing surfaces. The removal device has a rasp element to remove material from the second surface during a movement in the longitudinal direction along the second surface.

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.

An elevator system for a building, wherein an elevator shaft becomes taller as the building height increases during a construction phase, includes a self-moving construction-phase elevator car guided on a guide rail section(s) for conveying persons or goods during the construction phase, an assembly platform arranged above the car from which the guide rail section is elongated upwards in a rail assembly phase, an upper protection platform temporarily fixed in the elevator shaft on which the assembly platform is suspended via a cable-based lifting device or is suspended in the rail assembly phase, a lower protection platform, wherein the assembly platform is moved vertically between the upper platform and the lower platform by the lifting device during the rail assembly phase, and a docking device temporarily suspending the car on the lower platform to secure the car for evacuations, the docking device connecting the car to the lifting device.

An elevator guide rail installation bracket and installation method thereof, a positioning tooling, a bracket adjustment tooling, and an elevator system. The elevator guide rail installation bracket includes a guide rail bracket having a guide rail installation surface and a first adjustment surface that form a bend, a fixed guide rail installation position is provided on the guide rail installation surface; and a hoistway bracket having a hoistway installation surface and a second adjustment surface that form a bend; the first adjustment surface is adjustably connected to the second adjustment surface to adjust the relative position between the guide rail installation surface and the hoistway installation surface.

A method for constructing an elevator includes providing a hoisting machine unit, a guide rail line, an elevator car, a counterweight, and a hoisting roping; using the elevator car for transporting passengers and/or goods while the hoisting machine unit is in a first position; installing one or more guide rail sections into the guide rail line above a guide rail section of the hoisting machine unit; removing the hoisting machine unit from the first position; installing a guide rail section into the guide rail line in place from where the guide rail section of the hoisting machine unit was removed; hoisting the hoisting machine unit; mounting the hoisting machine unit to a second position which is higher than the first position; and using the elevator car for transporting passengers and/or goods while the hoisting machine unit is in the second position. An elevator arrangement is described for implementing the method.

The invention relates to an elevator arrangement, comprising a hoistway one or more vertically oriented guide rail lines in the hoistway for guiding vertical movement of one or more movable elevator units, and one or more movable elevator units mounted in the hoistway vertically movably along one or more guide rail lines, including at least an elevator car, preferably also a counterweight, and a hoisting roping; a movable support structure mounted in the hoistway for supporting said one or more movable elevator units below it via said hoisting roping, and a hoisting machine on the movable support structure for moving the hoisting roping, for thereby moving said one or more movable elevator units. Said movable support structure comprises a body portion, and a shelf structure projecting laterally from the body portion, and the hoisting machine is mounted on the shelf structure. The invention also relates to a method for constructing an elevator implementing the arrangement.

The invention relates to a method for constructing an elevator comprising constructing a movable machine room in the bottom end of a hoistway formed in a building under construction; and thereafter hoisting the movable machine room; and constructing an elevator car in the bottom end of the hoistway below the movable machine room; and providing a counterweight in the bottom end of the hoistway below the movable machine room; connecting the elevator car and the counterweight with a suspension roping; and thereafter hoisting the movable machine room to a first transport position; and thereafter mounting the movable machine room to the first transport position in the hoistway vertically supported on stationary structures; and thereafter using the elevator car for transporting passengers and/or goods below the movable machine room while the machine room is mounted in said first transport position and the elevator car and the counterweight hang suspended from the machine room by the hoisting roping; and thereafter hoisting the movable machine room upwards to a second transport position; wherein the second transport position is higher than said first transport position; and thereafter mounting the movable machine room to the second transport position in the hoistway vertically supported on stationary structures; and thereafter using the elevator car for transporting passengers and/or goods below the movable machine room while the movable machine room is mounted in said second position.
