Product Description:


A solution to problems with cast-in-place pile construction of 400~600m housing construction

Easier transportation, lower cost and higher efficiency
Tianyuan Jingang rotary drilling machines could be transported together with the drilling stems. Particularly, SWDM04/06 could be transferred using an ordinary carrier vehicle, thus reducing cost and increasing efficiency for users.

High stability and anti-tipping capacity
Arranging the main and auxiliary winches at the lower end lowers the center of gravity of the drilling machine during operation and transportation, and improves the stability of the complete machine. The steel wire rope is used to hoist the drilling stem and drilling rigs directly through the goose head pulley. This can prolong the service life of the steel wire rope.
Compact, flexible and highly maneuverable
Compact machine body ensures a satisfactory passage capacity and can accommodate pile pore construction in narrow space. It is a truly buster at the construction site.

Stable and reliable

Special chassis
The self-made special hydraulic flexible chassis structure suitable for the actual load is adopted. Meanwhile, the main and auxiliary winches are installed on the rotating platform, which remarkably reduces the tipping load and guarantees the stability of the complete machine fundamentally.
The position of the gravity center of the complete machine is optimized, with the stability angle increased from 10° to 15°. This guarantees operation stability on all dimensions of 360°.

Square-shaft casing structure
The box type square shaft casing structure is used for the mast deflection seat. The force of mast is directly transferred onto the trolley traveling mechanism, thus eliminating the stress of the rotary frilling force on weak links of the deflection seat and improving the structural stability and reliability.
Mast structure 
The high-strength anti-deform design is used for the drilling stem. The rectangular mast section is even wider on the guide rail direction. This can effectively reduce the structural stress of the mast and make it more suitable for the in-rock construction conditions with high-strength variable and constant load.
The main and auxiliary winches are installed on the platform, which greatly reduces the tipping torque of the operation device and the revolving inertia of the upper part of the platform and improves the stability of the complete machine.
Auxiliary landing leg
The standing leg hidden below the lower mast can not only act as the auxiliary support for drilling construction, but can also help you with other unimaginable matters.


High-grade configuration ensures high efficiency
The efficient and reliable engine is equipped with efficiency hydraulic transmission system, and this guarantees the strong power of the machine. The advance intelligent electronic control system can give full play to the efficiency of the machine. Meanwhile, the reasonable local structural design noticeably reduces the wearable and consumable.

Complete machine system
The engine of world-well-known brand is equipped with high-efficiency hydraulic transmission system. The advanced intelligent electronic control system can give full play to the efficiency of the machine. The complete machine system boasts advantages such as high reliability, fuel economy and high reserve power. The engine emission meets the European EPAC3 standard, which means the engine is environmental friendly. In addition, it can operate regularly even in alpine and high-altitude areas.
Power head
The compact machine has a large-torque power head and boasts high speed. This ensures high construction efficiency.

Hydraulic elements
The hydraulic system has been developed in joint efforts with a world first-class element manufacture to improve the hydraulic energy conversion rate of the element and reduce the transmission loss of pipelines of the system.
