A method for installing a guide rail of an elevator installation arranged in an elevator shaft, wherein the guide rail includes a multiplicity of guide-rail segments that are aligned and arranged in a row one beside the other, includes the following steps: fixing an aligning element in the elevator shaft at a first point in relation to an aligned and fastened first one of the guide-rail segments, wherein the first point is positioned on a route provided by horizontally directed parallel displacement of the route formed by the first guide-rail segment; fixing the aligning element at a second point, in the form of a reference point, in the elevator shaft, an aligning-element portion for aligning a second one of the guide-rail segments therefore being formed between the first and the second points; and aligning the second guide-rail segment relative to the aligning-element portion.

The present invention relates to a horizontally movable vertical shaft rope guide and a regulating method thereof which are suitable for guiding of hoisting containers in vertical shafts. The vertical shaft rope guide comprises a hoisting rope, and two hoisting containers suspended from the tail ends of the hoisting rope, wherein, cage guide ropes are led through guide cage lugs arranged on the two sides respectively, a tensioner arranged on the ground at the shaft top is connected to the upper end of each cage guide rope, and a connector arranged under a steel slot at the shaft bottom is connected to the lower end of each cage guide rope; a hydraulic cylinder is connected at the other side of each tensioner and the corresponding connector, and the hydraulic cylinder is connected to the tensioner or connector. During hoisting in the vertical shaft, the hydraulic cylinders are controlled to act in advance, to push the tensioners or connectors to move towards the center between the two hoisting containers, so that the cage guide ropes led through the guide cage lugs on the two sides of the hoisting containers get close to each other at the same time and wrap the hoisting container; thus, the horizontal displacement of the hoisting containers is restrained, and the impact of air flow on the two hoisting containers is minimized when the two hoisting containers meet.
