Installation
Installation notes
Adjusting the closing force of spring rope pulleys with sliding hub
On both sides of the spring rope pulley is a tensioning screw (SW 17). Turning it in the direction of arrow increases the pretension, turning against the direction of arrow reduces the pretension.
Thanks to the integrated sliding hub, there is no risk of damaging the spring in case of an error during tensioning.
Closing force/travel of spring rope pulley
The closing force can be adapted by pretensioning the spring rope pulley. The higher the pretension of the spring, the shorter, however, is the remaining travel. The maximum possible travel with the respective spring force (pretension) can be found in the adjoining diagram.
Example: If the spring is pretensioned only the required 6 revolutions, a travel of 4 m is possible. At the end, when the door will be closed, there will be left a force of approx. 62 N. If the spring is pretensioned one revolution more, the travel will be reduced to 3.6 m, but the remaining force in the final position will be approx. 66 N.
