  • Publication number: 20150360913
    Abstract: 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.
