Description of load limiter dynasafe
TM
Mecha 3.2
3.1. Presentation
The load limiter dynasafe
TM
Mecha 3.2 is a mechanical load limiter for wire ropes operating on the 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
TM
Mecha 3.2 is based on the deformation of the load limiter 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.
