Counterweight-Balanced Dual-Leaf Vertical Lifting

The Renlita Hinge system is a counterweight-balanced vertical lifting door designed for monumental dual-panel openings. Instead of relying on overhead tension springs or load-bearing structures, the system utilises concealed counterweights that allow the frame to rise vertically on a roller track behind the header.

• Structural Independence: The structural load is entirely contained within the jambs, completely eliminating the need for a load-bearing header or additional lateral supports.
• Optimised Hinge Configuration: Dual hinged panels allow taller openings with optimised stacking heights, ideal for monumental architecture.
• Fail-Safe Safety: Features a mechanical pin lock fail-safe device that automatically prevents door movement in the event of counterbalance or lifting device failure.
• Aesthetic Integration: Counterweights are fully protected and concealed by removable pressed sheet covers (aluminium or steel) for a clean architectural finish.
