3. Description of load limiter dynasafe
3.1.

Presentation

The load limiter dynasafe
principle of a potential-free contact which is tripped when the tension in the wire rope exceeds the
preset limit.
This load limiter is specially designed to manage one or two safety thresholds on small and medium
capacity overhead travelling cranes.
3.2.

Operating principle

The operating principle of dynasafe
body through a tangential force, which is proportional to the force exerted on the wire rope when
pulled.
When the deformation of the load limiter body is above a limit, the integrated micro-switch opens.
The contact is automatically reset once the tension in the wire rope is below the set limit increased
by a hysteresis value depending of the effort.
