Electronic speed adaptation system, HDL-d/HD4
How it works
During your work, when you approach the maximum capacity of the crane, a signal is sent via the RCL to the HDL-h valve, and the valve changes from 100% to 20% nominal oil flow.
As soon as you go back to a lower load moment, you will get the full oil flow again and 100% of the crane’s capacity.
Full protection of the crane’s construction
The HDL-h reduces the dynamic additional forces in the steel construction of our manually operated cranes (MCS cranes), thus extending the crane's life span. All our MCS cranes are equipped with HDL-h system.
