Hörmann SPU F40 4 mm wire rope for track application N, torsion springs

The wire ropes connect the bottom of the leaf to the cable drums on the torsion spring shaft. Through them, the springs balance the weight of the door. This 4 mm diameter wire rope is intended for Hörmann series 40 industrial sectional doors with track application N, manufactured from July 2001 to February 2013. At the end it has a thimble with a pressed clamp.

How to choose the right wire rope

• Diameter – Hörmann uses 4 mm wire ropes for drums of size 1 and 6, and 5.5 mm wire ropes for other drums.
• Track applications L and LD – have a wire rope with an end fitting (terminal), not a thimble.
• Garage doors – for garage sectional doors with track application N, the 3 mm wire rope is intended.

Before ordering, compare the diameter and length of the old wire rope and the data on the door's rating plate. If you are not sure, write to eshop@saver.sk.

Replacement

The wire ropes are tensioned by the force of the torsion springs. Before replacement, the springs must be released safely; an improper procedure can cause injury or the leaf to fall. We recommend leaving the replacement to a specialist. We can do it in the Košice and Prešov regions; more on the page.
