Features:
1) Its novel hexagonal cross section structure features light dead weight and strong bearing capacity;
2)Its hoisting, luffing, swing, telescopicing and other mechanisms adopt manual proportional control and hydraulic drive, featuring easy and flexible operation, stable and reliable work, as well as stepless speed regulation;
3)Such safety devices as relief valve, balance valve, hydraulic lock and brake valve are equipped to prevent oilway overload and avoid accidents due to pipe fracture;
4)It adopts the flow saturation resistance technology, with the flow irrelevant to the load, so that the combined movements could have the stability and synchronization effectively ensured;
5)Three-axle dedicated chassis, broad vision, as well as luxurious and comfortable decorations;
6)It adopts a FAST gearbox and a 6×4 drive plus easy and flexible hydraulic power steering;
7)Such safety devices as torque limiter and height limit device, as well as a complete lighting system are equipped to ensure safe and reliable operation, and facilitate operation at night;
