Simple operation, high working efficiency, stable and reliable, high efficiency, low noise, low heat generation.
1.Advanced development & analysis make sure the reliable design.
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 wire rope 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.The boom interface is made of strong steel plate, and the U-shaped arm is used for the crane above 8T, which makes the cross-section bending resistance stronger.
5.The crane above 6.3T adopts square legs, which can better protect the cylinder.
6.Compact boom head and tail design, make the boom length to reach maximum, prolong the working life of the crane.
7.The integer lifting winch improved the work efficiency greatly and prolonged work life of hydraulic system
8.Integral boom head structure with more strength.Boom head adopting integral structure, greater intensity. Split head design reduces the boom head carrying capacity
9.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.
10.Anti-slewing impulse equipment that make vehicle running safely.
11.Water-based paint, more environmentally friendly .
