●  It is equipped with an advanced full hydraulic drive system and electrical control system;
●  Moment limiter can not only automatically measure the mass hoisted by crane and the angle of boom, but can also display the rated load, actual load, operating radius and the angle of boom;
●  All safety devices are overridden under assembling mode, while under operating mode, all safety devices are functioning;
●  Under emergency condition, the crane circuit can be shut off and all operations stopped by pressing the emergency stop button;
●  When the hook is hoisted to a certain height, the lifting operation of hook can be automatically stopped so as to prevent against the over-winding of hook block;
●  When the wire rope is released close to the last three circles, the electrical control system will automatically stop hook block falling operation and give an alarm through the buzzer and display;
●  When the operator leaves away from the seat or pulls up the unloading joystick, the unloading valve will be shut off and all operations will be ineffective so as to prevent against false operation;
●  The anti-tipping device of boom can effectively prevent against back-tipping of main boom;
●  Main winch (free fall) and luffing drum are equipped with electrically-controlled ratchet locking device;
●  Electronic level gauge can display the tilt angle of crane upper structure on cluster gauge display;
●  The monitoring system can monitor the condition of winch mechanism and crane tail in real time;
●  In the case of lightning strike, lightning grounding device and surge protection device can effectively protect against the damage of electrical system elements and against the hurt of operators;
●  It can achieve GPS satellite positioning, GPRS data transmission, equipment use status query, statistics and remote fault diagnosis.
