Capital Construction drilling rig which is Anchor Drilling Rig Crawler Drilling Rig for Small Space Anchoring pile construction.
The drilling rig is designed for working in narrow spaces, such as tunnel, culver and foundation ditch. With its rotating-percussion rotary head, it is suitable for drilling in stratum formations of sticky clay, sandstone as well as partially decomposed rock stratum. With down-the-hole hammer bit, it can drill in hard rock formation efficiently.
The emission standard of its power engine is TIER3(III) stage standard.
Main features
2,with big rotary torque ,long feeding stroke, effectively improve drilling efficiency.
3,The crawler moves by itself, equipped with the frame turning device, the device is easy to shift, fast and accurate to the hole.
4,Equipped with hydraulic gripper and shackle device, which can shorten drilling time and reduce labor intensity.
5,The main components of the hydraulic system are imported brand, the system is stable, reliable, long service life.
6,The power head adopts hydraulic variable-speed and hydraulic mechanical variable-speed mode, with different specifications of power head, which can meet the requirements of different drilling methods.
7,The hydraulic system adopts direct load feedback and fine-tuning variable, the power changes with the load, high efficiency and low energy consumption.
8,Equipped with power head rotation speed, lifting speed and vertical display device, hole positioning fast and accurate.

Under normal circumstances, big buyers buy goods for six months at a fixed price, but some buyers start to use quarterly contract prices, while other buyers think it is more favorable to change to a floating contract price. Rapid price changes make buyers unwilling to accept long-term fixed prices. In June 2009, the spot price fell by half, and the caustic soda buyer set the price of caustic soda supplied in the first half of the year at 390 US dollars per dry ton (261 euros per dry ton, northeast Asia offshore).
Asian caustic soda producers say that most buyers seem to be exploring other possible alternatives in the first half of 2010. At present, large caustic soda producers in Asia include the Shanghai Chlor-Alkali Company in mainland China, Tosoh Corporation in Japan, Hanhuo Chemical in Korea, and Formosa Plastics in Taiwan.
6000s Tunnel Construction Hydraulic Engineering Drill Rig/Drilling Machine
It is mainly used for hard alloy rotary drilling, screw drilling, pneumatic drilling with DTH hammer, pneumatic drilling with DTH hammer and casing, rotary jet, swing jet, fixed jet and other drilling technology;It can also be used in the engineering fields of tunnel pipe shed support, rock and soil anchorage, blasting hole, embankment reinforcement, ground source heat pump hole, hydrological well, foundation pile construction and geological disaster control.Note :Users can choose diesel engine power, motor power, diesel engine power/motor dual power.
1,Multi-azimuth luffing mechanism, the drill can realize multi-row and multi-angle drilling in one position.
Market participants recently stated that caustic soda buyers in Asia wanted to change the supply of long-term contract goods in 2010 and changed from the current two-year price fixing system to a supply contract that is more adaptable to changing market conditions. This week, major buyers such as aluminum smelters have started negotiations with local caustic soda producers for long-term contract prices for the first half of 2010.
