Abstract (en)
[origin: EP0755894A1] The load measuring system detects the compression of the springs (9) supporting the lift cabin (3) relative to a surrounding carrier frame (7) for detecting variations in the load within the lift cabin. The movement of the lift cabin relative to the carrier frame and the lift shaft is detected via an endless band (12) displaced in conjunction with the lift cabin and a cooperating pulse generator (13). This provides a signal (SL) which is evaluated for controlling the current for the lift drive motor (4).
