Abstract (en)
[origin: EP1538121A1] In an elevator control device there is a plurality of hoisting machines (9) provided apart from each other. Main ropes (13) are engaged to the car (2) and are passed around the corresponding hoisting machines (9), and the car (2) is driven to ascend and descend. The tension of each main rope (13) at a standstill of the car (2) before start is detected, and the car (2) is driven to ascend and descend by increasing or decreasing the outputs of the corresponding hoisting machines (9) in accordance with the above-mentioned detected values. Thus, even in the case where the load is unevenly loaded in the car (2) and the tensions of the main ropes (13) differ, the hoisting machines (9) drive the car (2) with suitable outputs, so the car (2) does not incline. <IMAGE>
