The hydraulic system is open-close variable system and the electrical system adopts CAN-bus technology. A color digital LCD, which is fitted in operator’s cab, can display the relative parameters effectively in real time. Furthermore, the electrical system can switch off crane when it is overloaded, cut off boom derricking motion when main boom and jib reaches limit position and carry out fault self-diagnosis.
