Industrial door torsion spring breakage prevention

The torsion spring anti-breakage coupling is a key component in industrial doors and other equipment that connects the torsion spring with the transmission system (such as the shaft, motor). Its core function is to cut off or buffer the power transmission through its own structural design when the torsion spring breaks or is subjected to abnormal force, preventing the fragments of the broken torsion spring from flying, the transmission system from being overloaded and damaged, or the door body from losing control and causing safety accidents.

product description

Product Application

Small torsion spring anti-breakage:

Material: Cold-rolled steel plate + surface galvanized

For 2-inch anti-breakage, the distance is not adjustable

Medium-sized torsion spring anti-breakage

Material: Cold-rolled steel plate + surface galvanized

Used for anti-breakage in 2-5/8 inches

Large torsion spring for breakage prevention

Material: Cold-rolled steel plate + surface galvanized

It is used for anti-breakage in 3-3/4, 5-1/4 and 6-inch sizes

The torsion spring anti-breakage coupling is the "last line of defense" of the industrial door safety system. Through the design of "normal power transmission + automatic separation in case of abnormality", it not only ensures the efficient operation of the equipment but also cuts off the risk transmission in emergency situations such as torsion spring breakage. It is a key component for balancing the performance and safety of the equipment. When making a selection, parameters such as the weight of the door body, the torque of the torsion spring, and the working frequency should be taken into account to match the appropriate overload threshold and structural form (for example, the pin type is suitable for low-frequency scenarios, and the friction plate type is suitable for scenarios that require repeated resets).
