SINOVO
1 / 3
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 motor is Germany Rexroth and which increases work efficiency more than 20%, and totally saves about 20% energy compared with traditional system.
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.
It is equipped with Cummins engine specialized in engineering machinery with strong power.
Driving head reserves reinforced power (push & pull force). Push & pull force can be increased to 1800KN, which ensures the safety of the big diameter construction.
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.
Wireless-control walking system can be used to ensure the safety in the process of walk, transfer and load & unload.
Full lifted manipulator is convenient for loading and unloading drill rod, which can greatly reduce the workers labor intensity, and improve work efficiency.
With Φ114×6000mm drill rod, the machine can be used in medium field area, meeting the requirement for high efficiency construction in small place.
Main hydraulic components are from the international first-class hydraulic component manufacturer, which greatly improve the reliability of the product performance and safety.
Electric design is reasonable with low failure rate, which is easy to maintain.
Push & pull contains rack and pinion push-pull system, which is good for high efficiency, long lifespan, stable work, and maintenance is also convenient.
Steel track with rubber plate can be loaded heavily and walks on all kinds of roads as well.

The rotation and thrust features a USA Sauer closed-circuit system. The rotation motor is originally imported from Poclain (France), and the push & pull motor is manufactured by Rexroth (Germany). Other main hydraulic components are sourced from top international first-class manufacturers to ensure reliability and safety.
The machine has a maximum thrust and pullback force of 1200KN, which can be increased to a reinforced capacity of 1800KN to guarantee safety during large-diameter construction projects.
The equipment is powered by a high-strength Cummins engine specially designed for engineering machinery, outputting 264/2200KW of engine power.
The machine uses Φ114×6000mm drill rods. It is optimally configured for medium field areas and meets the demands for high-efficiency construction projects in smaller or confined locations.
The machine supports a maximum pullback pipe diameter of Φ1500mm and a maximum construction length of up to 1000m, both depending on specific soil conditions.
Safety is ensured through a wireless-control walking system, which keeps the operators secure during walking, machine transfer, loading, and unloading operations.
