Springs
The heart of the sectional
door; torsion springs
Torsion spring is used to balance the weight
of the sectional door. These springs are
installed towards the bending direction of
the spring, creating a force. This force is
connected to the underside of the door by
means of ropes and the weight of the door
is transferred to the springs. For this reason,
the load on the door opener is reduced to
around 20-40 kg.
