The cable has an attachment Ä43Ü which operates a switch when the gate is in an end position. There is a locking mechanism holding the gate to the link. The link has a guide piece Ä70Ü and a two-armed lever Ä80Ü pivoted to the gate and the locking mechanism is on the arm that is not attached to the gate. The drive motor has three pulleys around which the cable passes.</p> |
