SUWNARD Tried-and-test CAP System and Hard Rock Drilling

  This system is typically made by an auger housed inside the casing that driven by two independent rotary table. It is an ideal technology for drilling projects in restricted urban area to eliminate vibration and disturbances to adjacent structures, reduces noise emissions and avoids waste materials due to the use of bentonite mud. Especially SUNWARD’s CAP system can work with 500-2000mm Dia. of heavy-duty DTH hammer and external air compressor to penetrate the hard rock stratum. The specially designed full hydraulic or electrical pile driver has a 920mm Dia. of strong mast, 80ton of rated extraction force, 5000mm of width during working to ensure its high stability and efficiency in working. The SWSD rig worked with DTH hammer has achieved wonderful performance in several tough projects in China for 500-1500mm Dia. and Max. 36m depth of cased drilling. Presently in China it is considering as an ideal system to overcome the hard drilling in complicated geological condition at favorable cost and for environment-friendly drilling in restricted urban area. 

  Nowadays SUNWARD as the biggest manufactory of drilling & foundation equipment in China offers a full range of construction method to the industry for application of Jack-in precast concrete pile, Boring Pile, Continuous flight auger pile, Cased auger pile with DTH , Soil Mixing Wall, Diaphgram Wall, Anchor Drill and etc. with machines ranges from 16tons to 1200tons weight.

  At present SUNWARD has a stable sales of foundation equipment in Europe market, besides in the past 2010 it also achieved a wonderful sales in new emerging market such as India and Vietnam thanks to the high equipment demand in SEZ(Special Economic Zone) projects and UMPP ( Ultra Mega Power Projects).
