More and more excavator manufacturers can now deliver excavators with a control system installed in the factory. The advantage for the user is that everything is function-tested, quality-assured and CE-marked directly from the factory. The risk of problems with the control system is significantly smaller then it is always mounted the same way and tested carefully at the factory.
Retro-fitted control systems
Still, most control systems today retrofitted, although the trend towards factory fitting is clear. During the installation the original joystick is replaced and a shunt valve is mounted in the excavator to control the flow of the hammer line. A very important part of the assembly is the final tuning of the system and the respective function. If this is not done well then the excavator run the risk of having to high fuel consumption or not having the smooth operation that the operator wants. With XControl, this is very easy thanks to the built-in auto-tuning that ensures that the correct amount of oil coming to the tiltrotator. Steelwrist can also be ordered with the proportional control systems SVAB RT or GP.
