The drilling rig can be equipped with mud pump, foam pump and generator according to user needs. The rig also comes standard with a variety of winches.High working efficiencyDue to the full hydraulic and top drive rotary propulsion lifting, it is suitable for various drilling processes and various drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so the operation efficiency is high.low costThe drilling on the rock is mainly based on the down-the-hole hammer drilling process. The down-the-hole hammer rock drilling operation efficiency is high, and the drilling cost per meter is lower.high outrigger trackedThe high outriggers are convenient for loading and transportation, and can be loaded directly without a crane. Crawler walking is more suitable for muddy field movement.Positive and negative axial pressure adjustmentThe best impact efficiency of each impactor has its optimum shaft pressure and rotation speed. During the drilling process, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more matching axial pressure. The impact efficiency is higher at this time.The role of the lubricatorEfficient and durable lubricators and oil mist pumps. During the drilling process, lubricate the impactor running at high speed all the time to maximize its service life.Rig chassisIt can be a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis.The value of second-hand mobile phones in the same industry is higherAs the main components of the drilling rig are imported brands, and the main frame of the drilling rig is made of high-quality high-strength low-carbon alloy steel, which increases the overall strength and is very wear-resistant, as well as the more important hydraulic system, which is very valuable.  Detailed PhotosOur AdvantagesFAQQ: Are you a manufacturer or trading company?A: We are a specialized manufacturer. Q: What are your main products, and used for?A: Our products include core barrel, casing, drill rod, drill rig and other drilling parts.They are used for mineral exploration, geological drilling, Q: How about the delivery terms?A: 1.Payment: T/T, L/C, Western Union, Paypal, 30% deposit in advance and rest before delivery2.
