……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: Rotary drilling rig piling generally dozens of meters deep, when the next reinforced concrete generally divided into several times? In other words, a few meters per hour of reinforced concrete?
- Under the reinforcement cage, according to the hole depth or design, the general section is about 22 meters. For example, the hole depth of 47 meters, 22 meters a steel cage needs 2 sections, the middle welding.Concrete transported by tankers, general tanker has 8 parties, 10 parties, 12 Parties, a car in the majority, according to Kong Shen, the pile diameter is not the same, the need for mixed soil is also different. Example: 1 meters of pile, depth 35 meters. At 0.785 meters per meter, 35 multiplied by 0.785 is 27.475 squares of earth. But there will be special conditions such as collapse hole, so it is unstable.
- 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: What kinds of rock entry models are there in the 31 rotary drilling rigs? Request introduction!
- The rock type, strictly speaking, SR250 above can be into the rock, but the real into the current mainstream rock drill rig or 31 SR280R and SR360 three generation, the future of C8 series rotary drilling rig SR285RC8, SR315RC8, SR385RC8 as the main push models will gradually replace SR280R and SR360.
- Q: Rotary drilling rig on the floor under the floor with steps
- The probability of rollover is relatively high, and the auger must be parallel with the vehicle, and the width of the two sides of the track should be kept the same width.
- Q: What kind of geology is a rotary drill suitable for?
- Rotary drilling can be used in all geological conditions, but only in accordance with specific geological conditions, to take appropriate construction methods drilling tools
- Q: How many times a day will the drilling machine be used?
- Look at the actual situation, usually of rotary drilling rig, such as diameter 120cm length of 30 meters, the geological conditions in general, 1.5 to 2 hours to complete. You can calculate the amount of work done every day.
- Q: Can the rotary drilling rig of fine round gravel soil move?
- Coarse gravel soil, fine gravel soil, (density capacity 650kpa) using the current engineering auger can work smoothly.
- Q: Which is faster, the reverse circulation rig or the rotary drill?
- The speed of rotary drilling is faster than that of positive and reverse drilling under any conditions. And much faster.
- Q: 31 rotary drilling rig electromagnetic valve is what?
- Solenoid valve according to different requirements can be achieved two, three, two, five, etc..Solenoid operated solenoid valve is divided into two kinds of AC and DC(1) the voltage of an alternating current electromagnet is usually 220 volts. It is characterized by large starting force, short commutation time and low price. But when the valve core is jammed or the suction is not enough, the iron core can not be sucked on, and the electromagnet is easy to burn out because the current is too large, so the work reliability is poor, the operation has the impact and the service life is low.
- Q: How can the drill pipe cracking of rotary drilling rig be welded?
- Must use two treasure welding! The welder is not as strong as the ordinary welder! And ensure smooth formation, so as not to put the rope when the power head of the inner key to cause unnecessary wear and tear, and even accidents, but also pay attention to cracking, serious, serious, to return to the factory, do not force yourself
