……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:How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?
1 、 impact drilling hole: adapt to relatively soft formation.2, rotating drilling hole: adapt to relatively hard strata or gravel layer, backfill and other complex geological conditions.3. Hole drilling of casing drilling machine: it is suitable for stratum with flowing sand and underground water.4. Drilling by rotary drilling machine5. Drilling under karst geological conditions6, reinforced cage, concrete7 、 deepwater drilling pile fixed platform
Q:What kind of rotary drill rig is it?
This is a large rotary drilling rig. General 31, Xugong have production. The price is around 5 million. Small rotary drilling rig, Shandong, Tengzhou has produced, suitable for rural housing piling, cost-effective, about 300 thousand of the price. You can look down our strong product.
Q:What is the drilling speed of rotary drilling machine?
I just want to know that a range is the speed at which a hole is drilledIf you want to say the condition, the pressure is 6 tons. The construction stratum is a common surface soil layerQuaternary unconsolidated layer, gravel layer and bedrock layerAbout two meters in diameter
Q:How about the collapse of rotary drilling machine?
You have to use a large proportion of mud. If you can't do it, you'll have to use a reverse circulation rig or an impact drill.
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Mud: the mud of rotary drilling rig is made of mud while drilling, and more and more waste slurry is produced. The slurry of rotary drilling rig is made in advance, drilled and drilled again2: Mobile: rotary drilling machine, some mobile devices, and some walking style. Rotary drilling rig is tracked mobile
Q:Can the auger drill be drilled into the two - longest granite of the 1200kp?
Drill the special effort, we have the hardest to 900kp, take the drill, hold up, are a large column, an hour about 2 meters into the rock. Hard, then the hole time is very long, slowly grinding.
Q:The structure and principle of hydraulic rotary drilling rig are discussed!
By the hydraulic motor drives the reducer drive, you must first master the hydraulic principle, main pump suction, drive motor, hydraulic energy into mechanical energy, mechanical energy to drive motor reducer, reducer which drives the chain walk, referred to as the four round area,
Q:What is the difference between punched pile and rotary pile?
Punching pile is the impact of heavy hammer falling, the soil or rock to disperse or break, and then floating through the mud of these debris floating, and then pumping, the pile side of the soil compaction, I think it can be ignored. Punching piles are usually rock - in. They just break the rock and squeeze it out.
Q:Construction scheme of rotary pile driver
Overview of drilling hole of rotary drilling machineAccording to the geological conditions of this project, and design requirements, combined with the pile foundation design parameters and requirements of the owner, the engineering pile drilling technology using rotary drilling rig, concrete using commercial concrete and steel reinforcement cage hoisting welding forming, lashing, catheter perfusion underwater concrete.
Q:My rotary drilling rig has broken several rotary drilling pipes. Is it my drill pipe or the reason of my rig?
Hello, this is a lot of reasons, 1. may be man-made problems, 2. can also check the machine, 3. can check the drill pipe 4., to see if the geological suitability of your choice of drilling rod
