Application:
Door locking devices with and without certified locking device The lift door locking devices of the AV series are used for monitoring and locking 1- and 2-leaf lift landing doors. These safety locking devices meet the requirements of the Lift Directive 95/16/CE and of EN 81-1.

The door locking devices are available with light-metal die-cast and thermoplastic enclosure, with one or two locking elements, with rightside or left-side version, with lever, pull strap or built-in bearing blocks. The safety function can be monitored through the transparent cover. The locking bolt has a 22-mm travel, which guarantees that the mandatory engagement depth of 16 mm is safely maintained after the lowering of the door. The emergency release can be operated from outside by means of a triangular key.

Operating principle of the certified locking device:
The European Lift Standard EN 81-1 stipulates that: „It shall be impossible, from positions normally accessible to persons, to move a lift with the landing door open or unlocked after a single action, which is not part of the normal operating sequence.“ Our door locking devices with magnetic certified locking device of the AV 15, AV 20 and AV 25 type meet this requirement. They are therefore admitted for passenger lifts.
