Disclosed is an elevator inspection system, the system having: a robotic platform configured to inspect a hoistway; a platform propulsor operationally connected to the robotic platform; and a controller operationally connected to the platform propulsor, wherein the controller is configured to control the platform propulsor to propel the robotic platform vertically within the hoistway.

The arrangement comprises an installation platform movable upwards and downwards in the elevator shaft, at least one light source arranged at a predetermined position in the elevator shaft below the installation platform and producing a vertically upwards directed collimated light beam, at least one primary digital imaging device positioned on the installation platform and being arranged to take electronic images of the light beam hitting the photosensitive sensor of the at least one primary digital imaging device or of a pattern created by the light beam on a reflective or transparent screen positioned at a distance in front of the photosensitive sensor of the at least one primary digital imaging device, whereby the horizontal position of the installation platform in relation to the elevator shaft can be measured from the electronic images taken by the at least one primary digital imaging device.

A universal bracket for a rail system includes a positionable and alignable main support and at least one mounting point for at least one rail of the rail system. The main support has two guides that are inseparably connected to the main support in order to guide one plumb bob in each case, the mounting point and the guides being arranged in fixed positions relative to one another.

The disclosure relates to a lift installation having a lift car which can be moved along a guide rail. The lift installation here comprises at least a first pair of rollers and a second pair of rollers. The guide rail runs between the two rollers of the first pair of rollers and between the two rollers of the second pair of rollers. The lift installation also has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between the point at which the retaining force takes effect and the center of gravity of the lift car, and therefore the lift car is subjected to a first torque.

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 apparatus includes a stationary part being attachable to an elevator guide rail element at a predetermined height above a joint between two consecutive end-on-end mounted elevator guide rail elements. An elongated measuring frame having an upper end and a lower end is supported from the upper end with an articulated joint at the stationary part. A number of inductive sensors are positioned on the measuring frame, whereby at least a part of the inductive sensors are directed in a first direction being the direction between the guide rails towards a tip of the guide rail elements, said part being further divided into two sub parts so that a first sub part of the inductive sensors is directed towards the upper elevator guide rail element and the rest are directed towards the lower elevator guide rail element. The apparatus further includes a connection board for the inductive sensors, a visualization device, electronics, and a power source.

In a method for carrying out an installation process in an elevator shaft of an elevator system, an assembly device is inserted into the elevator shaft. The assembly device includes a support component, a mechatronic installation component retained by the support component and a control apparatus. At least one assembly apparatus (tool, sensor or component) is arranged on the support component. The support component is fixed in a fixing position in the elevator shaft. After the support component has been fixed, an actual position of the at least one assembly apparatus is determined relative to the installation component. Using the determined actual position relative to the support component, the at least one assembly apparatus is received by the installation component and an assembly step is carried out using the received at least one assembly apparatus.

An elevator system including: an elevator car configured to move through an elevator shaft; a first guide beam extending vertically through the elevator shaft, the first guide beam including a first surface and a second surface opposite the first surface, wherein the first guide beam includes a first section; a beam climber system configured to move the elevator car through the elevator shaft, the beam climber system including: a first wheel in contact with the first surface; and a first electric motor configured to rotate the first wheel; and a beam climber assembly pod operably attached to the beam climber system, wherein the beam climber assembly pod is configured construct remaining sections of the first guide beam as the beam climber assembly rides on the first section of the first guide beam.

A method and a mounting device for carrying out an installation operation in an elevator shaft of an elevator system include a mounting device having a carrier component and a mechatronic installation component held on the carrier component. In a displacement phase, the carrier component is displaced relative to the elevator shaft and positioned at different heights within the elevator shaft. In a mounting phase, a mounting step is carried out at least partially automatically, wherein a mounting device is removed from a magazine component disposed on the carrier component and installed on a shaft wall of the elevator shaft. In a stocking phase, a magazine component is stocked with mounting devices outside the elevator shaft and, in a loading phase, the stocked magazine component is disposed on the carrier component.

A method for mounting a guide rail in an elevator system elevator shaft first carries out mounting steps by a mounting device having a carrier component, an installation component and a control apparatus controlling the installation component. The control apparatus determines, on the basis of an actual position of the mounting device and a desired position of a guide rail to be installed, a position of a marking on a shaft wall of the elevator shaft relative to the actual position of the mounting device. Based on the marking, an installation step determines the desired position of the guide rail. The marking is applied to the shaft wall by the installation component. The previous steps are followed by the steps of alignment the guide rail in relation to the marking and fastening the guide rail to the shaft wall, which steps can be performed manually by an installer.
