Application of torsion spring in balance system of sliding door

The application of torsion spring in the balance system of sliding door:
The torque produced by the balance system should be equal to the weight of the door body. No matter how large or how many doors are, they can be used to push, open and close, so as to move up and down easily
The fatigue frequency of torsion spring should exceed the corresponding opening and closing times of door body to ensure no fracture within the set service life
The composition of the balance system: wire rope wheel, solid shaft, bearing bracket, tension spring, flange, steel wire rope. According to different door size and weight, the corresponding thickness and strength are required to ensure the safe and stable operation of the whole balance system within the service life
