Floating torsion spring tension adjustment system
An overhead door having a floating spring adjustment is presented. Tension is applied to a torsion spring while the door is in the open, minimal tension state. One end of the torsion spring is fixed to a spring tension trolley. The trolley translates within a trolley guide mounted to the building structure. The other end of the torsion spring is fixed to a shaft running through the torsion spring. This allows the torsion spring to change in length as the number of coils shrink and grow through door operation thereby eliminating the “snake-like” or serpentine appearance from an improper fixed torsion spring length.
