How to install torsion springs in industrial doors

Tension springs are individuals of many spring products, ranging from straight cylinder to various variations, and even various shapes of hooks can be designed and formed. It is the reverse application of compression spring. The application range is generally less specific than the product category, but the operation control is at a higher level than compression spring.

Industrial door lifting methods are divided into three types: upper slide lifting, vertical lifting and semi-vertical lifting. The torsion spring is installed as follows:

1. Slide lift industrial door: The installation method of torsion spring is the same as that of the upper slide telescopic door.

2. Vertically lifting industrial doors: It is necessary to install a tower wheel to balance the torsion spring torsion and door weight. Because the torsion spring always bears the same weight of the telescopic door body, only by changing the wheel diameter, that is, changing the torque, can the torsion spring torsion and the door weight be balanced, so a cone wheel is needed.

3. ​​The torsion spring of the vertical lift door needs to be pre-tightened when installed. The force is equal to the weight of the door (generally 3.5 to 4.5 turns). The length of the wire rope is usually determined based on the cone reel, and it is necessary to make sure that the cone wheel is fully wound from large circles to small circles.

4. Semi-vertical lift industrial door: It is necessary to install a half tower wheel to balance the torsion spring torsion and door weight. The door is lifted vertically The cone wheel part of the half cone wheel is used, and the flat wheel part of the half cone wheel is used to lift the upper sliding part of the door.

The above is the installation method in industrial doors.
