Abstract
The invention relates to an industrial truck, comprising a vehicle frame, a lifting framework (), the lifting framework () having a first lifting frame () which is attached to the vehicle frame, and at least one lifting arrangement () which is movable in the vertical direction (V) relative to the first lifting frame (), and a measuring arrangement () which is provided in order to detect a movement of the first lifting frame () and/or of the lifting arrangement () relative to the vehicle frame. In this case, it is provided according to the invention that the measuring arrangement comprises at least one optical sensor () by means of which the movement of the first lifting frame () and/or of the lifting arrangement () can be sensed contactlessly. Furthermore, the invention proposes a method for determining the lifting height in a lifting framework of an industrial truck, with the distance covered by the first lifting frame () and/or by the lifting arrangement () being detected by sensing of a surface () of the first lifting frame () or of the lifting arrangement () by means of an associated optical sensor ().
