advantage
1.Independently developed a new generation of large series folding arm truck crane, the whole machine adopts finite element lightweight design, light weight, small installation space.
2.Compact structure, beautiful; The new octagonal arm section has greater lifting capacity and strong bending and torsional resistance under the same amplitude.
3.Rotary table high seat control, with better working field of view, optional remote control operation.
4.Regenerative control and new sequential expansion control system are adopted to reduce the pressure loss of boom expansion, improve the load expansion capacity and the working efficiency of the whole machine.
5.The rotary double-stage double-cylinder leg is adopted to improve the adaptability of the site, and has a larger span to improve the working stability of the whole machine.
6.The double reducer is used to drive the rotation, the rotation action is more stable and powerful, and the braking effect is better; Onboard hydraulic proportional valve, good micro-motion performance, and can carry out compound action, high operating comfort.
7.The standard high-power radiator ensures that the oil temperature of the crane is not high for a long time.
8.Standard hydraulic control torque limit valve, to ensure that customers use the crane more peace of mind.
9.Standard L-HM(CY) XCMG wide temperature hydraulic oil, can be used in winter and summer.
