Goodeng International GS420-LS
Goodeng International GS420-LS

Model Number: GS420-LS


1.Close-circuit system is adopted for rotation system; automatic variable system is adopted for push & pull, clamping and walking and it is under load-sensitive control. Advanced hydraulic system raises more than 20% productivity, reduces about 50% heat, and saves more than 20% energy compared to traditional one.

2.The machine is equipped with Cummins engine, with high efficiency, large power, low fuel consumption, low noise, and strong ability in construction.

3.Four bar linkage luffing structure is adopted for main girder, which highly increases entry angle range and ensures the large angle and rig tracks are not off ground, having improved the safety performance.

4.Wire-control walking system can ensure the safety when the machine performs walk, transfer and load & unload.

5.The machine is equipped with φ76×3000mm or φ83×3000mm, and the machine body occupies a moderate area, meeting the requirement for high efficiency construction in small place.

6.Main hydraulic components are from the international first-class hydraulic component manufacturer, which greatly improve the reliability of the product performance and safety.

7.Electric design is reasonable with low failure rate, which is easy for maintenance.

8.The steel track with rubber plate is adopted for crawler, which can not only bear high load, but also satisfy walking on different roads.

9.Rack and pinion system is adopted for thrust &pullback, which is good for high efficiency, long life, stable working and maintenance is also convenient.
