Excellent and stable chassis performance / chassis system
The STC550 utilizes a double-axle drive that provides good trafficability and comfort under complex road condition with reliable performance. The rear axle is equipped with rubber suspension and V-shaped thrust lever, which provide less vibration and more comfortable traveling experience. The engine has a multimode power output function which reduces power consumption. The use of tipping over early-warning technology helps keep you safe on the job.

Ultra long and super strong boom system with highly sensitive load lifting capacity
Features a five-section boom made from high strength steel and optimized U-shaped section which reduce weight and significantly improve safety. Jib mounting angles are 0°, 15°, and 30° to allow quick change-overs between different operating conditions so as to improve working efficiency of the machine.

Highly efficient, stable, energy-saving, and adjustable electrical proportion hydraulic system
Load feedback of hydraulic system, constant power control, piston pump and electrical control valve provide powerful lifting capacity and excellent micro-mobility. Unique steering buffer guarantees smooth braking.

Safe, stable, advanced, and intelligent electric control system
Uses a self-developed controller SYMC specially designed for engineering machinery. The application of CAN-bus fully digital network control technology ensures stable control signal
