⚙️ Application & Assembly

This LHW industrial spring is mounted on the right side of the door in double spring systems (inside view). It is ideal for industrial buildings, workshop doors, large sectional doors, and systems with high opening frequencies. The spring precisely balances the door weight and reduces motor load and wear.

Safety Notice: Industrial springs are under extremely high preload. Installation must only be carried out using tensioning tools (Ø 12.7 mm), personal protective equipment (PPE), and a de-energized drive. Tormeister 24 strongly recommends installation by qualified personnel – risk of death if operated incorrectly!

🏁 Practical example

This 67×6×639 mm LHW spring was installed as a replacement in a heavily used industrial door. The result: smoother operation, more stable mechanics, and significantly less stress on the drive – optimal performance in continuous daily use.
