Jining Hengwang Mining Machinery Co., Ltd.

Product Application

HZ-20 rig is the use of gasoline-powered engine, easy starting, reliable operation, easy to operate and is equipped with an artificial synthetic diamond drill bit, mainly for roads, airports, ports, docks, dams and other concrete works, Drilling the core of the new products. The core function of 400-5000mm, mainly in highway and to take concrete, limestone, foundation, etc., compressive, flexural test. Research core is also very good.
