STC250T4

Strong boom   

■ 35m telescopic boom, Reach a new height of 35.5m. 

■ Larger cross-section boom, achieving a load moment of 1078KN·m. 

■ Boom section overlap increased, resulting in higher torsion resistance and bending resistance.  

■ 8m lattice jib, triangular structure for stable operation.

Powerful chassis    

■ DF Cummins ISLe290 30 engine, FAST 9-speed synchronizing gearbox, rubber suspension, 12R22.5 wire tire.  

■ Frame torsion resistance verified by 20k times of reliability and safety cycling test.  

■ Outrigger span expanded to 5.18m×6.4m (largest among this tonnage in the industry), stable base.  

■ Low deck carrier for drive stability.

Precise hydraulics   

■ Load sensing hydraulic system: higher efficiency with less consumption. 

■ Constant-pressure powered luffing: smoothly luffing down, free from impact of load fl uctuation.  

■ Big-flow piston slewing motor: slower slewing with larger torque. 

■ Power control: Engine speed reduced by 12% in operation, less fuel needed, less noise generated.

Smart control    

■ CAN-BUS system: instant transfer of information, as fast as 20ms. 

■ Fault diagnosis: BCM controller for fault detection and easy maintenance. 

■ 7’color display & smart panel & IO power distribution: user friendly. 

■ Safety guarantee: SANY, Load Moment Indicator monitoring load and wire rope conditions.
