……More info  


1. Adopts the complete OEM Caterpillar retractable-crawler dedicated chasis,Its telescopic scope between the two crawler ends extends from 3000mm(at transportation) to 4400mm(at work). Undercarriage with expandable and removable tracks by means of hydraulic cylinders, guarantee exception stabbility in any type of ground. It has considerable traction force which allows easy movement even in the most difficult job sites.
2.Takes international top CAT Diesel engine with electric injection, turbocharged and air inter-cooling system. It is high reliability, fuel economy and power reserves. Emissions meet standard EPAC-Ⅲ.
3.The winches are positioned in the lower part of the mast, in front of the cabin, so that the operator can constantly check the proper operation. Thanks to the fact that the cable moves parallely to the mast, flection is not created on the upper part of the mast and operating life of the cable is therefore much longer. Tail positioned winch is available for heavy-duty type.
4.New design parallelogram system, computer optimized design and simplified pin connection system featured with nice appearance, great driving force and good stability, especially shaped to fit crowd system, allowing working radius adjustment always maintaining the mast in vertical position. The parallelogram system is easily for convenient transform between transportation and working conditions.
5.Self-erecting mast, high level anti-shock technology and high-strenth material steel attribute to that max torque can be applied all over the mast length. 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:I love inventing super rotary drilling rigs. Can they dig wells? Can they move rocks? How deep can they hit?
Because now the double power head drill wells with rotary drill rod is rotary drill, but few are more than 2 meters in diameter with direct rock itself, very fast, low cost of the machine drill many times than rotary drilling. I suggest you check the pile hole drill on the Internet, or the China Sea Hengtong, it is easy to find information.
Q:What are the polymer slurries used for rotary drilling machines?
The polymer mud of rotary drilling rig is a kind of organic macromolecule material which is made up of anti collapse material, sediment treatment material and anti leakage agent. The earliest producers of polymer mud in China are CIS and Chennai, both of which are imported. The price is much higher than that of bentonite, and the dosage is much smaller
Q:Price of small rotary drilling rig
This is mainly due to customer driven rotary drilling rig drilling depth and pile diameter limit, the depth and diameter of the smaller the lower the price, on the contrary, the higher the price.
Q:The difference between the rotary drilling bored pile and long spiral bored concrete pile?
The difference between the rotary drilling bored pile and long spiral bored concrete pile is the main construction machinery, the hole is not the same. Long spiral for small diameter bored pile, more than 800 of the use of rotary excavation.
Q:What kind of stratum is suitable for rotary digging pile?
Construction, according to different soil and geological conditions, according to the following provisions choose different drill bits:
Q:Rotary drilling rig how telescopic, I mean, what power so that it extends out of step by level, it extends out in a certain order?
Friction compression drill rod (abbreviation: friction rod, friction drill rod)It is generally used for drilling in soft formation, which can be used for drilling mud, soil, sand and egg (drift). The friction drill rod is usually made up of 5 sections, each of which is 13 meters long and 1~4 times longer than each steel tube. Drilling depth of about 60 meters.
Q:Rotary drilling rig on the floor under the floor with steps
Back on the truck, slowly, especially when the center of gravity. In short, pay more attention to it! Before loading, the machine must be adjusted to the state of transport, on the trailer when the spiral digging back up, down the trailer when it is good, straight down. Obey the command, careful driving, generally no accident.
Q:Hole drilling price of rotary drilling machine
The geological conditions of deep hole depth into the empty aperture method whether it contains steel cage contains reinforced cage contains concrete auxiliary equipment whether party a gas station how to calculate the construction of reasonable charge pile head break
Q:What brand of rotary drilling rig is efficient?
The working efficiency is high, the domestic rotary drilling rig is relatively good in the Futian leiwo rotary drilling rig, driving very fast, with less, I was in Linyi, bought the first 09 years, 11 years and bought 2, now 3, around the project.
Q:What's the difference between the main oil pump imported from the rotary drilling rig and the home made main pump?
. Under normal circumstances the main hoist is responsible for the drill pipe and the drill bit weight can be, but when the drill will be mud suction and pore wall friction in the air, so the main hoist lifting force of the drill bit and is generally greater than the gravity, sometimes if there are some things above the pressure in the collapse of the drill rod can better reflect the main hoist lift characteristics.
