Categories: ,

1.German Rexroth automatic variable system is adopted for rotation,push &pull,clamping and walk.with load sensitivity control.Advanced hydraulic system raises more than 15%-20% productivity,and saves more than 15%-20% energy compared with 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.Driving head reserves reinforced power(push&pull force).Push&pull force can be increased to 960KN,which ensures the safety of the construction in the construction of big diameter.
4.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.
5.Wire-control walking system can be used to ensure the safety in the process of walk,transfer and load & unload.
6.Reversible manipulator is convenient for loading and unloading drill rod,which can greatly reduce the workers labor intensity,and improve work efficiency.
7.With Φ89x4500mm or Φ102x4500mm drill rod,the machine can be used in medium field area,meeting the requirement for high efficiency construction in small place.
8.Main hydraulic components are from the international first-class hydraulic component manufacturer,which greatly improve the reliability of the product performance and safety.
9.Electric design is reasonable with low failure rate,which is easy to maintain.
10.Push pull contains rack and pinion push-pull system,which is good for high efficiency.long lifespan,stable work,and maintenance is also convenient.
11.The steel track with rubber plate is adopted for crawler,which can not only bear high load,but also satisfy walking on different roads.
