Highly Secured Control System
There are two separate modes for working and installation. The safety and supervision system have multiple features including an electronic level gauge, machine-leaving stop action, emergency electrical control and a complete set of safety and monitoring device. The load moment limiter does not require calibration, keeping you safe while decreasing auxiliary operating time. An optional slewing area limit device further improves the safety of the equipment.

Excellent Operation Performance
Each micro-motion is smooth and stable thanks to maximum load regulation and electronic-over-hydraulic control. A real-time queried electronic load chart provides instant data and feedback.

Reliable Operation
The SCC550E is designed with a wide safety margin. Its critical components, such as pumps, valves, motors and reducers are all of high-quality from world-renowned brands. In addition, the advanced flow distribution system is load independent and adopted to the hydraulic system. The control system is fully capable of stable function in extreme weather: from extreme cold to heat and even high altitude weather. The sensor is also protected against lightning strike while the entire machine is closed-wired with waterproof / dust-proof protective grade up to IP65.The machine passed the verification test of the strength over twice that of the industry leaders, proving its reliability.

Convenient Maintenance Technology
The maximum adjustment time is only 10min/person, while daily maintenance takes no longer than 30min/person and repairs take no longer than 2h/person. There is an additional optional GPS remote monitoring system enhancing maintenance and management.

Powerful Lifting Capacity
The SCC550E has power to get the job done. The wide-track chassis ensures excellent overall land operating stability within 360° range of rotation, with a maximum boom lifting capacity of 203.5t•m. The length of fully-extended boom reaches 52m and the rated single rope pull of main boom and auxiliary winch is 6.5t.

High-Efficiency Operating Speed
The main and auxiliary lifting winches record a top speed of 120m/min, while the luffing winch are able to reach 72m/min.

Flexible Configuration
There is an optional free fall winch for main and auxiliary lifting winches.

Easy Transport
The SCC550E is easy to move to and from destinations. The maximum transportation width of whole machine can be shortened to 3.36m with the telescopic function
