Winding tool for torsion spring for sectional garage door |
摘要 |
A winding tool for tightening a torsion spring for a sectional overhead door. The winding tool features two half hub assembles that wrap around an overhead door shaft, wherein a translational sprocket is disposed on the hub assemblies. The hub assemblies connect to the winding cone of a torsion spring via fingers that engage the hub assemblies. A winding box is removably attached to the hub assemblies. The winding box features a worm gear that engages the translational sprocket. A handle bar can be rotated with a drill to cause rotation of the worm gear. Rotation of the worm gear causes rotation of the translational sprocket and ultimate winding of the torsion spring.
