The door closing weight is suitable for retrofitting on existing lift landing doors.
It serves to implement the specification of EN 81-20 220.127.116.11.4: As written below;
‘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’.
Simplified this means: When the doors are opened, for whatever reason, outside of the unlocking zone, they must have a device fitted to them that ensures that the doors will then automatically close.
HOW IT WORKS:
The closing weight ensures a permanent and constant (linear) closing force of 2kg.
Thus the doors close automatically until the door lock 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.
