……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:What is the difference between bored pile and rotary pile?
Bored pile is wider, and all kinds of machinery or artificial way of pile foundation construction can be called bored pile. The rotary bored pile is a kind of bored pile, especially the drilling method of rotary drilling machine. Other drilling methods include spiral drilling, positive circulation, reverse circulation drilling, impact drilling, etc..
Q:Where is the main volume pressure sensor of XCMG 1050 rotary drilling rig?
The sensor (English Name: transducer/sensor) is a detection device, can feel the measured information, and can feel the information, according to the law must transform into electrical signals or other information in the form of output required to meet the information transmission, processing, storage, display, record and control requirements.
Q:Rotary drilling rig application
The main purpose of rotary drilling rig is to:Bored pile foundation engineering rotary drilling.
Q:200 rig footage every day how many meters
Footage number and geological conditions, drilling performance, operator proficiency, construction site conditions have a relationship, and to say that footage of the day, and the length of pile pile diameter has a diameter of 1.2 meters, with 60 meters long, 2 meters under the casing 0.5 hours, casing well Party A, the Commissioner General to look at. General situation, the first 20 meters of drilling, probably within 1 hours, 20-40 meters, less than 1.5 hours, 40-60 meters, less than 2 hours. Hope to be of help to you.
Q:How a rotary drilling rig
You are not open rotary drill, the dray and digging machine is the same.
Q:The difference between the rotary drilling bored pile and long spiral bored concrete pile?
The long auger rig includes two parts: hydraulic walking pile and drilling system. Pile frame adopts hydraulic walking chassis, a high degree of automation, self walking and 360 degree rotation, is equipped with four hydraulic legs and a walking cylinder to aid in walking and turning at the same time increase the overall stability in construction, can machine transfer. Column for folding box type column, flange connection, column by using two pieces of high thickness mask and bending technology of large bending machine, the two welding seam welded and column inside every 60cm welding of four reinforcing ribs fixed, increasing column torsion bending resistance. The column is controlled by two variable pressure hydraulic cylinders to take off and take off. The drilling system comprises a power head and the output shaft of the power drill head and screw drill is hollow, pile machine into a long spiral hole, drill pipe through the center of the concrete or mud pump] {concrete CFG pile construction, which can be a drilling machine once completed, can also be used to dry hole grouting, altering tool can also be taken deep mixing a variety of Engineering construction.
Q:Can rotary drilling machine be used in rock layer?
The rock layer depends on the hardness, I have seen the 280 rig called 700KPA mudstone and 2200KPA granite, and 250 rigs played 4000KPA to beat rock schist, the key lies in the construction of rotary drilling rig, a rock speed is very slow.
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 much oil is used in the 31 rotary drilling rig?
Check whether the fuel tank is adequate and the oil is normal;
Q:Rexroth leveling sensor rotarydrilling rig
Intake air temperature sensorRole: provide air temperature information for correction of fuel injection and ignition timing. Effect: idle speed is low, easy to flameout.
