Product Description:



A drilling rig is a machine which creates holes in the earth sub-surface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and are called augers. Drilling rigs can sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earth's crust.


Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth's crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.

Multipurpose design for cylinder crowed system. Sensor and control center realize real-time measurement of the inclination angle, auto adjustment of mast verticality and inching adjustment.
6.Crowd system by means of long stroke hydraulic cylinder or crowd winch separately, are option for your exact request.
7.Rotary head with variable displacement motors and one high spin off speed. And rotary is extremely reliable, it has been disgned in order to gurantee a very compact, efficient and powerful rotary. The transmission group of rotary is made up of a hydraulic motor and new power shift purposely studied and designed to obtain maximum perfomance. During the drilling phase, the rotary has the entire power of the diesel at its complete disposal. Adapter of rotary is essential to absorb the considerable shock connected to the high speed of the main winch.
8.Telescopic kelly bar with guide made by high quality specially for high boring strength and torque force. Available with friction or inter-locking type.
9. All the main hydraulic components(pumps, valve, motor, connector) are from well-known international brands such as Bosch-Rexroth, brevini, which ensure the stability, reliability, high-efficiency and energy-saving of the entire system
10.Electronic controlling system is an innovative system, developed by Osaint, which controls and monitors the operation of the machines. For ease of operation, the system is controlled by a touch screen located in the cab. The system function is to enable the machines to perform different functions more efficiently. A dedicated power module electronic control and CAN-Bus system ensures the main pumps and Disel engine to work at their most effective and productive stages.

Q:Rotarydiggingmachine operating permit test how
Rotarydiggingmachine also called rotary drilling rig. The utility model is a tool for road traffic and high-rise building construction. The rotary drilling rig is a kind of comprehensive, it can use the short helix bit dry digging, can also be used in wet digging rotary drill mud case. Rotarydiggingmachine with hammer drill hole digging work pieces after hard formation. If the enlarged head drilling tool is used, the reaming operation can be carried out at the bottom of the hole. Rotary digging machine adopts multi-layer telescopic auxiliary drilling drill pipe, less time, low labor intensity, without mud circulation deslagging, cost saving, no pollution, infrastructure construction is especially suitable for the construction of the city.
Q:What's the price of the 31 sr630rc8 rotary drilling rig?
Compared to other brands imported, Carter engine is poor. So buy the main part of Carter's 31. The price is not clear, should be in 4489
Q:I love inventing super rotary drilling rigs. Can they dig wells? Can they move rocks? How deep can they hit?
Now, the rotary drilling will be replaced by the new double power wells drilled by the China shipping line
Q:How can the drill pipe cracking of rotary drilling rig be welded?
Tell you, you remember, it's a friction welded joint! If it is not friction welding, it is deceptive. Because the oil drill pipe is friction welded. There is a welding and cutting equipment company in Harbin. I used to work as a technician there. Can help you with this problem.

English is rotary drilling rotary drill rig, in addition to the configuration of various rotary bucket operation, installation of casing drilling, with rolling tube device and grab for will casing construction; with telescopic guide rod grab underground continuous wall construction, with DTH of hard rock crushing construction; operation device can also be replaced for jet construction and circulation of construction; construction of pile foundation can also configure other forms of hydraulic hammer, diesel hammer etc..
Q:What brand is good for rotary drilling machine?
If you choose domestic. Well then. Zhonglian, CSR, 31, XCMG essentially different. 31, the South Locomotive and Xugong initial use of Carter chassis. And they claim to be imported cards. Of course, Carter chassis is also made in China (Xuzhou production? It sounds like I forgot who said it. Now this point few imported Carter chassis may. Because the freight can not get through. The advantage of the Carter chassis is quality stability (that doesn't mean that all homemade chassis is not good). Standard unification. The drawback is maintenance and a high cost of maintenance. The fuel costs are substantial today. It's not a small expense either. About homemade sites. Zhonglian, 31, XCMG and CSR are developing. And the earliest development of United china. From the beginning of doing the digging, are in their own production of homemade bottom. Quality is also very pass. Xcmg. 31, recently also made homemade bottom. There seems to be some technical difficulty. South Locomotive Work late. There is news that the homemade bottom is Sichuan bonlee of CSR (non reliable).
Q:What are the hidden dangers during the construction stage of rotary drilling rig?
The rotary drilling cast-in-place pile is also divided into dry hole, soil sampling rotary pile and reverse and reverse rotation pile
Q:What happened to the black smoke from the exhaust pipe of the rotary drilling rig?
Check air intake is not enough, mainly empty, filter blockage, air flow meter, no damage, etc.
Q:Can the rotary drilling rig of fine round gravel soil move?
Gravelly soil is an unconsolidated or argillaceous cemented soil with a particle size of not less than 50% of the total mass of 20mm.
Q:What are the differences and relations between machine, trenchless drilling rig, horizontal directional drilling machine and rotary drilling rig?,
Horizontal directional drilling machine belongs to trenchless drilling rig. Horizontal directional drilling rig is a trenchless pipeline laying equipment for communication, electric power, gas, tap water, rainwater, sewage, heat, chemical and other industries.
