Superior Performance
Powerful Lifting Capacity
Wide-track chassis is designed to ensure excellent stability within 360° rotation; the maximum lifting capacity of main boom is 203.5t·m (55t×3.7m), the maximum length of main boom is 52m, and the rated single line pull of main and auxiliary winches is up to 6.5t.
Excellent Operation
Load-sensing system, limit load regulation, and electronic-over-hydraulic proportional micro-speed controls ensure smooth micro-movement and stable operation.
Efficient Operating Speed
Cummins 6-cylinder engine with rated power of 132kW@2200rpm, maximum torque of 800Nm@1400rpm; outmost layer line speed of main and auxiliary lifting winches is 120m/min, and that of luffing winch is 72m/min.
Safety and Reliability
Safe Control System
Switch between the operation and installation modes is more convenient and reliable, and the crane's functions including electronic level gauge, off-line stop, emergency electric control, and closed-circuit monitoring ensure your safety; load moment limiter is free of calibration, which provides you with a safer operation and costs you less time.
Reliable Function Guarantee
Sufficient safety margin in structural design; the control system runs stably even in extreme cold / hot weather, high altitude and sandy regions; the key components like pumps, valves, motors, and reducers of international well-known brands are reliable and stable; advanced hydraulic technology, lightning protection, waterproof/dustproof devices are adopted to ensure the whole machine's stability and reliability; the crane passed the verification test of the strength twice higher than that in the industry.
High Return & Low Cost
Optimized Transportation
With telescopic crawler, the maximum transport width of whole machine is 3.36m, ensuring it to be transported freely.
Convenient Maintenance
It takes no more than 10min/person to adjust, 30min/person for daily maintenance and 2h/person to repair the machine. GPS remote monitoring system is optional for maintenance and management.
Flexible Configuration
Free fall winch is optional for main and auxiliary lifting winches; slewing area limit device is optional to improve the crane's safety.
