SWDM15C Rotary drilling rig

The most professional manufacturer of underground works construction equipment
Sunward Intelligent started with independent research and development of hydraulic static pile driver. Through more than 10 years of engagement in underground works, Sunward Intelligent has successfully developed the professional underground works equipment series with the most complete categories and the highest geology adaptability and become an enterprise that is able to provide comprehensive solutions (design, equipment and construction) for underground works construction under complicated geological conditions. The Company has developed the powerful multi-function drilling machine, pipe following drilling machine and rotary drilling machine that are unique in this industry.
The first hydraulic static pile driver highly coupled with mechanism, electricity and hydraulics (winning the National Second Prize in Terms of Scientific and Technological Progress) integrates various patented technologies and has gained a market share as high as 60%. This product has been derived from the original one through innovation in terms of construction method and theory and is regarded as a milestone in the application history of pre-cast concrete pipe piles in the foundation industry of China.
Sunward Intelligent developed the rotary excavating series products with the most complete spectrums in China, with power head output torque ranging from 40KN to 420KN.M and construction bore diameter ranging from 350MM to 3,000MM. Its theoretical system has formed the only two monographs in this professional industry, namely Research and Design of Rotary Drilling Machine and Rotary Drilling Machine, Construction and Management.
Committed to the field of underground works construction
Sunward Intelligent insists on technological innovation and constant improvement in development and construction of underground works equipment, and boasts the most complete construction equipment and construction technologies suitable for underground works construction process in China in the aspects of foundation piles, even wall, base treatment, new pile types and new technologies.
Tianyuan Jingang series, a good helper for construction of small-bore pile foundation

Target market
Sunward Intelligent is the first in China to launch Tianyuan Jingang series drilling machines, which are designed specifically for bore forming construction of cast-in-place piles in civil projects and are very suitable for construction in various special, narrow and crawl spaces, such as bridges, culverts, the inside of buildings, workshops, metro, and municipal pole lines.

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.
	Winch 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
