The crane adopts polygon-section boom（Patent No.: ZL 2004 2 0035755.7）whichmakes the stress distributed more evenly, the load bearing condition improved, the deadweight reduced, and the load carrying capacity of boom improved.

The boom adopts two-section independent telescoping mechanism (Patent No.: ZL 2004 2 0035753.8) which greatly improves the lifting performance of themiddle-long boom.

The crane adopts double slewing mechanism and closed control circuit（Patent No.：ZL 2004 2 0035751.9）which make gear drive continuously and smoothly. In addition, it has the advantages of good cushioning performance, high accuracy of motions, high utilization ratio of energy and low heat of systemwhile the crane starts or brakes.

The crane adopts load sensor and electro-hydraulic proportional control system (Patent No.: ZL 03 2 27135.2) which can improve the jogging performance of motions.

The electric system has the faulty self-diagnosis function, which can monitor the working state of electronic control system in the course of running crane. If the abnormal phenomena happen, it can find out faults by a certain way to calculate, start the corresponding fault running modules and then display the corresponding information on interface. In this way, the service man can find out the faults and do maintenance at once.

The crane adopts CAN-bus control technology which ensures the high reliability of data transfer.

The crane adopts limit load control technology which can ensure the engine power to be full used and prevent it from shutdown due to overload.

The crane is equipped with a load moment limiter with multifunction which can ensure high safety, reliability and accuracy.

The crane adopts an operator's cab which can tilt 20°to broaden operator’s view.

The derricking mechanism adopts four modes, e.g. high speed, middle speed, low speed and jogging, to meet the requirements under different working conditions.

The driver’s cab adopts an advanced reversing rear display system which displays rear working area directly to make reversing much safer andeasier.
