Abstract: The current disclosure relates to a guide rail alignment method comprising attaching and aligning a first pair of elevator car guide rail sections in an elevator shaft and mounting a vertically moveable base between the guide rail sections. After the first pair of elevator car guide rail sections has been aligned, a target member comprising a target point is removably attached to a guide rail section, and a positioning light source able to produce a beam of collimated light is attached to the vertically moveable base, so that a beam of collimated light emitted in a predetermined direction by the positioning light source meets the target point of the target member. The position of the light source is then used to align a guide rail section of a second pair of guide rail sections. The current disclosure further relates to an elevator guide rail alignment arrangement.

Abstract: Method and system for installing the guide rails (1, 2), such as the car guide rails and/or counterweight guide rails, in an elevator shaft (3). The guide rails are installed by assembly in phases starting from the bottom (4) of the elevator shaft by placing one on top of the other guide rail sections (51, 52; 61, 62; 71, 72 . . . ) that are shorter than the whole length of the guide rail and by aligning the guide rail sections perpendicularly by means of the laser beam produced by a direction laser (8). The direction laser (8) is moved upwards along with progressive assembly of the guide rail. As assembly progresses the direction laser (8) is supported in the proximity of the top end of the topmost vertically aligned guide rail section at the time for aligning the next guide rail section to be installed in the vertical direction. These phases are repeated until the entire guide rail is assembled.

Abstract: A method in the installation of an elevator includes arranging a movable platform structure in the bottom end of the elevator hoistway with a temporary hoisting appliance in the elevator hoistway. The movable platform structure is lifted in the elevator hoistway with the temporary hoisting appliance. The final hoisting machine of the final elevator is installed from the platform structure and the final hoisting roping of the elevator is installed. The movable platform structure can be the final elevator car or at least a part of the final elevator car.

Abstract: A method for installing the hoisting roping of an elevator, the elevator including at least an elevator car that moves in essentially a vertical direction in the elevator hoistway, a hoisting machine, a traction sheave, and at least a plurality of diverting pulleys includes fitting a plurality of hoisting ropes to pass around a plurality of diverting pulleys as well as the traction sheave, the hoisting ropes, after the installation, forming the hoisting roping of the elevator. Each hoisting rope is guided to pass around each diverting pulley and/or the traction sheave such that a loop is formed from the part between the first and second end of the hoisting rope, the loop being fitted to pass around the diverting pulley and/or the traction sheave.

Abstract: A template for accurately positioning structural components of elevator(s) in a elevator hoistway(s), or of elevator hoistway walls or partitions in a building, includes a thin, flexible sheet of material adapted to be placed on a floor of elevator hoistway(s), has indicia on the flexible sheet of material to show locations, and points of attachment, of elevator structural components which are to be installed in the elevator hoistway(s). Tensioning elements attachable to the flexible sheet of material may be used to square up the flexible sheet of material. The template may be made by forming a thin, flexible sheet of material, providing indicia on the flexible sheet of material, and by providing tensioning elements to square up the flexible sheet of material. The flexible template may be placed on the floor of the elevator hoistway(s), squared, and the squared up template used as a guide to install the major elevator structural components. The template may, alternatively, be made of a substantially rigid, e.
