Our company is specialising in drilling rigs and drilling parts for decades. We have exported to more than 30 countries all over the world. We have kinds of drilling rigs, such as DTH (Down The Hole) drilling rig, Water well drilling rig, Piling drilling rig with different types of Truck Mounted, Trailer Mounted and Crawler Type. For drilling parts, we have the follwings: DTH hammers/bits, Tricone bits, PDC Bits, Button Bits, Chisel Bits, Drill Pipe, Pick Cutters etc.
Main features
Our rotary drilling rig absorbs the advantages of domestic and foreign famous brand products in design and techniques whose major performance parameter has reached international level of the similar product and whose components all adopts international famous brand products to guarantee the reliability of complete machine. It can be matched with drilling tools such as short spiral bit, common drilling bucket, and bailing drilling bucket etc. And can be drilled into clay layer, gravel bed, pebble bed and weathered mudstone bed. It has advantages such as high working performance, strong site adaptability, and obvious environmental protection effect etc., and is widely used in the pile foundation construction of railway and roadway bridges, urban traffic construction, and high-rise buildings etc, and also is the high efficiency drilling equipment for large and medium pile foundation engineering construction.
