4-5 Torque curve
It shows the torque curve for each model.
There may be variations, please use it as reference only.
NOTICE
If you increase the tension from factory set weight, the wire rope cannot be
extended to the full length. If the wire rope is exteneded beyond the maximum
spring rotations, the spring may be damaged.
If you decrease the tension too much, it may not retract the wire rope.
If you decrease the tension too much on the ERM-4S, ERM-6S and ERM-8S models,
the fall arrest device will be activated and lock the wire rope extraction.
