Specializing in the production of various models of column hydraulic rotary drilling rigs supporting drill pipes and diamond drill bits, the drilling rigs are intelligent, versatile, sturdy and durable. Is your good choice. Due to the diversity of the manufacturer's products, contact our business and he can recommend a product that is most suitable for you with quality assurance and the most reasonable price. /Pillar-type hydraulic rotary drilling rig uses carbide diamond composite drill bits and geological drill pipes for rotary drilling. It is suitable for advanced gas and water detection drilling on rock tunnel surfaces and mining surfaces. The notable feature of this drilling rig is that the whole machine is light in weight. Simple operation and low failure rate. The pillars themselves are equipped with supporting and fixed guide rails and are tightened upright. An adjustable connection plate is used between the guide rail and the column to ensure that the drilling angle of the drilling rig is adjustable. The pump station uses an explosion-proof motor to drive the oil pump to rotate, converting electrical energy into hydraulic energy (pressure oil) in the rotating oil circuit and propulsion oil circuit, and then transports the pressure oil to the hydraulic actuator through the one-way valve and reversing valve group on the console. It is simple and practical to realize various functions of the drilling rig. The manufacturer safely and conscientiously produces each accessory and processes it strictly to provide you with unlimited technical service support.
