[Features] 1. boom for large rounded form hexagonal cross section, the choice of GS70 high strength steel, light weight, strong bearing capacity, stiffness, significantly improve operational performance. 2. Synchronous telescopic boom, stretch, shrink rope are arranged in the boom arm inside, neat appearance, beautiful. 3.H type legs, span, strong anti-overturning ability, good stability. 4. Hydraulic system: use a single tooth associated pumps, dual power output (with motor output the oil). Use high-performance two-way hydraulic lock cylinder on hydraulic legs, telescopic boom luffing cylinder and use high-performance balancing valve on the hydraulic cylinder, making the operation safer. 5. With a height limit, a variety of security devices torque limiter, three times the protection of the main winch, so that manipulation is more secure and reliable. 6. owners valve with load feedback from the hook when you rise to a certain height, you can cut off the hydraulic system that allows manipulation of safe and reliable. Get off the throttle control mechanism is equipped with easy to use 7..
