SANY SCC550TB Crawler Crane

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 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; 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.

Excellent Operation

Maximum load regulation and electronic proportion controls ensure smooth micro-movement and stable operation. A real-time queried electronic load chart is provided, more conveniently and quickly;

Convenient Maintenance Access

It takes no more than 10min/person to adjust, no more than 30 min/person for daily maintenance and no more than 2h/person to repair the machine.
