1.The rotation and thrust is equipped with USA Sauer closed-circuit system,which is efficient,stable and reliable. Rotation motor is originally imported French Poclain brand which is famous all over the world, and push &pull motoris Germany Rexroth and which increases work efficiency more than 20%, and totally saves about 20% energy compared with traditional system.
2.Hydraulic control is adopted for rotation and push & pull, reducing the faults resulted from the aging of electrical components, realizing more stable and reliable control and quicker response.
3.It is equipped with two Cummins engine specialized in engineering machin-ery with strong power.
4.Driving head reserves reinforced power (push & pull force).Push & pull force can be increased to 2400KN, which ensures the safety of the big diameter construction
5.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.
6.Wireless-control walking system can be used to ensure the safety in the process of walk, transfer and load & unload.
7.Full lifted manipulator is convenient for loading and unloading drill rod, which can greatly reduce the workers labor intensity, and improve work efficiency.
8.with Φ114×6000mm drill rod, the machine can be used in medium field area, meeting the requirement for high efficiency construction in small place.
9.Main hydraulic components are from the international first-class hydraulic component manufacturer, which greatly improve the reliability of the product performance and safety.
10.Electric design is reasonable with low failure rate，which is easy to maintain.
11.Push & pull contains rack and pinion push-pull system, which is good for high efficiency，long lifespan,stable work, and maintenance is also convenient.
12.Steel track with rubber plate can be loaded heavily and walks on all kinds of roads as well.
