Various hinge bracket hole combinations
According to the actual size of the door, the spring can be produced to the required length.
Assembly spring plug is available.Function:
It is used for the top end of the spring, connecting the spring and the solid shaft, and has a torsion spring adjusting hole to facilitate the spring to increase the torque.
Spring end fixing flange:
Material: cast aluminum, light weight, high toughness, good strength, rust and corrosion resistance.
At the end of the spring, the spring is attached to the shaft bracket. When the top end of the spring increases the torsion force, the tail end acts as a support point to support the reaction force of the torsion.
When the door body is running up and down, the balance system overcomes the power of the door body's self-weight, which mainly comes from the torsion of the spring. The precise professional calculation formula is adopted to accurately configure the torsion spring according to the size, weight and lifting mode of the door body.
The optimal state of the torsion spring is that even in the case of power failure, without the use of motor, manual lifting of the whole door body can easily achieve the door in any position to stay.
