Hörmann 740 tension spring for track application Z

Tension springs balance a sectional garage door so that it can be opened easily by hand or by an operator. Spring No. 740 is only intended for Hörmann Series 40 sectional doors with track application Z manufactured from 1999. Doors with torsion springs above the door use different springs.

How to find the right spring

The spring number is on the door's rating plate, located on the inside on the right, and also at the top of the spring on the pulley holder. Hörmann tension springs are divided into Type 1 with one spring bundle and Type 2 with two bundles. Spring 740 is Type 1 – only order it if your original spring has one bundle and the number 740. Other Type 1 springs include 741 and 746. If you cannot read the number, write to eshop@saver.sk.

Safety

• Replace both springs – the springs are calculated for the same load. When one breaks, the other is close to its breaking point.
• A spring can break suddenly – so do not wait after one spring breaks; replace both.
• Leave the replacement to a specialist – we carry it out in the Košice and Prešov regions, see the Service page.

When replacing them, also check the wire ropes for track application Z and the tension cable holder.
