⚙️ Application & Assembly

This LHW spring is mounted on the right side of the door (from the inside) in double spring systems. It is perfect for industrial, hall, logistics, and workshop doors with high usage frequency. It reliably compensates for heavy door leaf weights and significantly reduces motor load and wear.

Safety Notice: Industrial springs are under extremely high preload. Work should only be carried out using tension rods (Ø 12.7 mm), personal protective equipment (PPE), and a de-energized drive. Tormeister 24 strongly recommends professional installation — risk of death if operated incorrectly!

🏁 Practical example

This spring was used in a warehouse to stabilize an unstable gate. The result: smoother operation, reduced motor load, and significantly increased operational reliability during continuous use.
