Product Description:

①. Base: CAT 329D(HHP)
②. Max pile diameter (mm): 1800
③. Max pile depth (m): 60
④. Engine: CAT C7 ACERT 187KW
⑤. Maximum nominal torque (kNm): 200
⑥. Undercarriage with expandable (mm): 3000-4300

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 essential difference between rotary drilling rig and rotary drilling rig?
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:Do you need electricity for rotary drilling rig?
Generally do not use electricity, the use of the rig itself gasoline engine power.When buying rotary drilling rig, you can ask for dual power, then you can use itElectrical, construction field, the two sides of the drill dragged two lines of electricity, oneMud pipe, one is cable.
Q:How to distinguish the performance of rotary drilling rig?
1. first of all, from the drilling equipment, the configuration of the drill rod to determine;2., from the special chassis to distinguish, its special get off, crawler frame using retractable structure, whether to solve the highway transport laws and regulations on the width of the machine requirements, and improve the whole machine in construction reliability and stability.3., followed by EFI turbocharged, cold engine, with high reliability, fuel economy and high reserve power is better. Computer induced load changes, direct injection electronically controlled fuel injection to provide accurate fuel injection, to ensure strong power and economic fuel consumption.
Q:Rexroth leveling sensor rotarydrilling rig
The intake pressure sensorRole: the intake pressure sensor is to provide engine load information, that is, throughWhen the pressure of the intake pipe is measured, the intake quantity is indirectly measured into the engine, and then the intake volume is converted into an electrical signal through an internal circuit to be supplied to the computer. Failure effect: causes the engine not to start easily or the idle speed is unstable.
Q:What drills are used to drill the hard layer of the rotary drilling machine?
I want to know how thick and big the pebbles are in you. Strong, weak, weathered, with double door fishing sand drill (pick teeth) can
Q:Kim Taixuan drilling operations and other brands of rotary drilling operation do.
Each manufacturer of rotary drilling rig has its own advantages and disadvantages, the truth is basically interlinked, but need to find out the performance of the machine, but also need a specific practice, you can try,
Q:Can rotary drilling machine be used in rock layer?
Models are generally not available, and large torque can be used for rocks that are not too hard. Rotary drilling rig is suitable for pumping out formation.
Q:There are several brands of rotarydiggingmachine
Let's say a joint venture brandCaterpillar: American brand, old brand, independent production. (CAT)Advantages: full strength, durable, strong, not easy to bad.Disadvantages: high price, high fuel consumption, short arm, small work range. Especially mine type models, large fuel consumption, after-sales service in general.Komatsu: Japan brand, excavator industry leader, the total cost-effective, independent production. (KOMATSU)Advantages: better strength, strong and durable, low fuel consumption, hydraulic pressure is its strong point, the overall coordination is good, the speed is very fast, not easy to bad, good hedge, used car good shot.Disadvantages: high prices, accessories expensive. (Note: because of its high share in China, the sub factory has many parts, so it is cheaper.)
Q:Does the rotary drilling rig need mud?
It needs mud and wall protection, and there are certain standards.
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.
