However, constant force spring systems are still able to approximate constant force. In order to do so, the diameter of the coil must remain constant, or close to constant. In standard constant force spring behavior, the user must first overcome the spring’s full load by extending the spring beyond 1.25 times its diameter. After that, the coil can be extended further by applying nearly constant force.
