Sany SCC550E 55ton crawler crane mobile crane
Sany SCC550E crawler crane's maximum lifting capacity is 55 tons, with multifunctional boom system, the crane may support a combination of up to 11 types of operating conditions. The 55 ton crawler tower suits for various business requirements.
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.
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
