1.Advanced development & analysis means make sure design is very reliable.
2.Using two-section telescopic cylinder design, one of the cylinders push the second large boom, another cylinder
push the rest of the telescopic boom by the pulley block and wirerope. To ensure that the crane has strong lifting
capacity in the middle distance and effectively protect the wire rope in the boom.
3.The more symmetrical center design of pentagon & hexagon boom make it has bigger anti-bending capacity.
4.compact boom head and tail design, make the longest boom length, prolong the working life of the crane.
5.The integer lifting winch improved the work efficiency greatly and prolonged work life of hydraulic system.
Boom head adopting integral structure, greater intensity.
6.Split head design reduces the boom head carrying capacity.
7.Self-design & developed slewing machine with greater drive force can meet varied requirements of working situation.
8.Lifting mechanism hydraulic winch relies on disc spring and friction brake, stable and reliable, efficient, low noise,
small calorific value; Rely on hydraulic balanced valves balancing weights when falling, greatly improve product reliability.
