Electronic speed adaptation system, HDL-d/HD5
The HDL-d/HD5 is an electronic speed adaptation system, which ensures that the crane automatically adapts the speed to the current RCL loads or EVS angles.
HD5 - The operating systems of the crane control the lifting speed and thereby the acceleration of the load independently of the crane operator (e.g. electronically controlled pressure-compensated proportional control valve.).
- The dynamic additional forces in the steel construction of the crane are reduced
- The crane's life span is extended
- In case of EVS angles, the reduced speed makes out an active part of securing the stability.
