Ultra Groove tension bush
The new cultivation method requires more pendulum movements of a screen installation. This also means more wear and tear of the pull wire.
Fortunately, we have come up with a solution.
ALWECO has developed a special tension bush for pull wire systems that reduces wear to a minimum. This Ultra Groove tension bush is supplied as standard with all ALWECO screen systems. The Ultra Groove tension bush has a spiral-shaped groove into which the pull wire is guided during extending and retracting. Because of this guide, the thread does not make any sideways contact, always retains its original shape and always remains in the right place, which means that the thread hardly wears out.
An additional advantage of the new Ultra Groove tension bush is the way it can be applied. The tension bush of two parts, so that it can be easily fitted around a shaft. With new installations, it is no longer necessary to slide the tension bush over the drive shaft beforehand, and with renovations, it is no longer necessary to disconnect the drive shafts in order to replace the tension bushes.
