The electric proC control system comes with 2 levers and 2 pedals or 4 levers and 2 pedals.
The Kesla proC control system is operated normally with two minijoysticks – or now as on option with two larger Maxi joysticks. Operators used to mechanical controls systems have not been that keen to adapt the mini joysticks. Now the proC 2+2 with joysticks and 2 pedals makes it easier to change to the electric control system.
The new control system is available with as 2 + 2 or 4 + 2 version. The movements are based on similar mechanical system’s movements. Both options are built on Kesla’s own proC control system. The steering valve options are the Parker L90LS or K170LS. The new system has been design-protected. Changing from the 2-lever system to the 4-lever system takes about half an hour. Kesla has a quick-coupling for this purpose. This would be beneficial especially in big companies or in companies renting machinery such as cranes.
Mechanical controls creates strain to the arms and hand joints when steering movements are strong and the trajectories vast. Joystick controls function softly and fluently with short movements. Additionally, the crane movements are easily and driver-specifically adjustable. The adjustments include general speed settings, acceleration and slowing ramps, control pre-settings (truck, forwarder, excavator) well as rotator’s rotating direction. The adjustments can be saved with the operator’s or work type’s names in six memory locations.
When a driver uses the new control system, icreased productivity can be guaranteed as the electric control is, despite of its soft movements, very quick and precise. Sales of the proC Maxi control system started officially in June 2019. The cranes ordered during the summer are being produced in the end of the year 2019. Source
