Door closing weight kit 2kg

Intended use

Mounting example

The door closing weight is suitable for retrofitting on exisiting lift landing doors.
It serves to implement the specification of EN 81-20 5.3.9.3.4:
In the case of landing doors operated by the car door, a device (spring or weight) has to ensure that the landing door closes when, for whatever reason, it is opened when the car is outside the unlocking zone.

Mounting examples

Description

Mounting example: door closing weight kit

The closing weight ensures a permanent and constant (linear) closing force of 2kg.
Thus the doors close automatically until the door bolt engages, which is a great advantage compared to closing springs. These often have too little tension and force when the door is closing or they have too much tension when the door is open, so that it is difficult for older door motors to keep the doors open.
The closing weight is attached to the landing door carriage by means of a PP cord over a diverter pulley and universal mounting angles. The door weight is constructed so that even older door motors can open the doors completely.
