A small detail can often
make a BIG DIFFERENCE.

The majority of electromechanical load limiters available on the market use disc-springs, which are chosen purely for economic reasons but have the disadvantage of not guaranteeing consistent performance over time, especially when exposed to dynamic loads, such as in the case of overhead cranes. Limiters that use disc-springs must therefore be periodically recalibrated. Other types of limiters do not use springs but exploit the flexibility of a metal body, with even worse results in terms of reliability and precision.

Danfos uses steel coil springs,
that guarantee calibration will remain unchanged for the entire life of the limiter
and are sized according to the capacity of the equipment, in order to obtain more precise calibration. The use of steel springs is one of the many reason why you should choose Danfos.
