Large crane HMF 9520: First live demonstration

The cranes are equipped with a new slewing system with two motors, which enables even smoother operation and particularly precise work. The proven RCL safety system from HMF has been updated with two new functions: The PCC function (Progressive Crane Control) dampens mechanical or hydraulic vibrations during sudden deflections of the control levers so that crane movements remain smooth. This makes crane work more effective and reduces wear. The PFC function (Progressive Flow Control) regulates the delivery volume of the pump if the operation requires more delivery volume than the pump can deliver. This guarantees that no crane functions are stopped, even in extreme situations.

The new crane will be equipped with the patented, tilt-dependent EVS stability system, which works without measuring the outriggers. If required, EVS can be deactivated with the new AutoSwitch function when the extension boxes are fully extended and the support legs are in contact with the ground. According to the company, the EVS system, which was introduced back in 1998, is the longest-established electronic solution for stability in the loader crane sector. EVS stands for "Electronic Vehicle Stability" and permanently monitors the vehicle tilt and actively adjusts the load torque of the crane to the limit of the vehicle stability. EVS only becomes active when the current stability limit is reached and reduces the movement speed of the crane to a safe level. The system stops the crane movement when the maximum vehicle tilt is reached. EVS is therefore an active stability system that takes the current load status of the truck into account.

The new HMF 9520 replaces the HMF 8520 crane model and will be delivered from the fall. Founded in Højbjerg in 1945, HMF has been building loader cranes since 1953 and today offers them with load capacities from 0.5 to 95 mt. HMF's German subsidiary has around 120 partner companies. The company is certified according to DIN EN ISO 9001:2000. ms
