The method comprises installing a lowermost first section of guide rail elements, moving a guide rail element upwards along a row of already installed guide rail elements with a transport apparatus, connecting the guide rail element to an upper end of the row of already installed guide rail elements and attaching the guide rail element to a wall of the shaft from a transport platform, moving the transport apparatus downwards along the row of already installed guide rails in order to fetch a new guide rail element.

The method comprises measuring the shaft with measuring equipment from a movable transport platform, whereby the form of the shaft and the position of the fastening points for the guide rails is determined based on the information received in the measurement phase, attaching fastening brackets to the guide rail elements and adjusting the fastening brackets based on the measurement results before the installation of the guide rails takes place so that the guide rail elements provided with the fastening brackets can be lifted in the shaft and attached to the fastening points without further adjustment of the fastening brackets.

Examples of the present disclosure describe systems and methods of determining online identity reputation. In aspects, an online identity of an entity may engage in online interactions. The content provided by the online identity may be accessed and analyzed to determine interaction characteristics and reputation metrics for the online identity. Based on the reputation metrics, the online identity and/or entity (and content therefrom) may be filtered from further online interactions. In some aspects, interaction data may be stored in a data store. An interaction mapping component having access to the data store may analyze the data store data to determine mappings between online identities, entities and interactions. In at least one aspect, an opt-in certificate system may also be provided. The opt-in system may provide an online identity or entity a certificate to securely validate identity.

A roller guide assembly for an elevator device, the roller guide assembly comprising a base member having a mounting means for mounting to the elevator device, the base member comprising a shaft support member; a roller wheel for engaging a guide rail to be rolled on the guide rail; a shaft on which the roller wheel is bearing-mounted, the shaft being straight and non-rotatably supported by the shaft support member, and a vibration dampening element, the vibration dampening element comprising an elastomer body arranged between the shaft and the shaft support member for dampening vibration of the roller wheel and for isolating the vibration from the base member. The shaft is attached to the shaft support member by the vibration dampening element forming a single attachment point for the shaft. The elastomer body is configured to form an elastically spring-loaded universal joint for the attachment of the shaft to provide a universal degree of freedom of an angular movement of the shaft and the roller wheel in relation to the base member.

A rack for a stairway guide suitable for providing good grip in curves comprises a bendable strip body, said bendable strip body comprising a first main side and a second main side, the first main side being provided with a series of equidistant engagement elements, each element being chosen from i) a hole, and ii) a protrusion. Both longitudinal sides are provided with a series of indentations. Being bendable, a stairway guide can be manufactured easily by bending the rack in the desired shape defined by the stairway guide.

An installation device used in an elevator shaft has a first carrier with first and second carrier ends, a support element pivotably arranged on the first carrier end, and a holding apparatus holding a displacement apparatus by which installation material can be displaced in the elevator shaft. When the installation device is in an installation position, the first carrier end is supported against a threshold of an elevator shaft door opening by the support element and the second carrier end is supported at least indirectly against a shaft wall that is opposite the door opening. The holding apparatus is arranged on an upper side of the installation device in the installation position such that the displacement apparatus is supported from above on the holding apparatus.

A stair lift device laid upon a staircase can support upward and downward movement of a platform of the device along stairs of the staircase. The device has two side supports in at least partial contact with the stairs of the staircase for supporting movement of the platform, and each side support can include a rail of the device along which the platform moves.

An elevator guide having a base attached to an elevator component, a guide riding along a portion of a rail and a spring biasing the guide in contact with the rail. The guide includes one or more of the following: (i) a guide support member operably associated with the guide for movably supporting the guide so that the guide can move toward and away from a corresponding surface of the rail member wherein the guide support member has a plurality of spring engagement sections configured to vary a system effective spring rate; (ii) a roller including a non-metallic rim molded about a bearing; (iii) two independently adjustable stops and, (iv) an opening adjustment member mounted about a notch in the base to vary the distance between the base and the rail. The opening adjustment member has a width and/or depth greater than a width and/or depth of the notch.

The present invention discloses a self-climbing robot for installing an elevator guide rail, which comprises a climbing mobile platform, a working mobile platform, a rectangular parallelepiped frame and a PLC control unit. The frame is fixedly provided with a first platform, a second platform, a third platform and a fourth platform from bottom to top, the top end of a screw provided vertically is fixedly connected with the fourth platform, and the bottom end of the screw is fixedly connected with the first platform; the climbing mobile platform and the working mobile platform are provided with a nut engaged with the screw and a driving mechanism capable of driving the rotation of the nut, respectively, the driving mechanism comprises a driving motor and a pulley box, the working mobile platform is located above the climbing mobile platform, both the climbing mobile platform and the working mobile platform are slidingly connected with the frame, and the climbing mobile platform and the working mobile platform are only capable of sliding in the vertical direction. The self-climbing robot for installing the elevator guide rail according to the present invention can automatically complete the task of measuring a well and installing a guide rail, and can self-climb in the elevator well.
