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 material steel pipe do the drill pipe use?
A rod that is connected and used to transmit power in a drilling tool. The common components of drill string are drill bit, drill collar, drill pipe, stabilizer, special joint and kelly. The basic functions of drill string are: (1) lifting bit; (2) applying drilling pressure; (3) transmitting power; (4) conveying drilling fluid; (5) carrying out special operations: squeezing cement, dealing with underground accidents, etc..
Q:What is the minimum diameter of a bored pile?
The minimum diameter of the bored pile is 310 mm;
Q:31 What about the performance of the auger rig?
Domestic equipment is more than the price, preferential margin, financing efforts, sales services, after-sales service, and 31 in the price, preferential margin, pre-sales, after-sales service and so on are good.
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:What brand is good for rotary drilling machine?
If you choose domestic. Well then. Zhonglian, CSR, 31, XCMG essentially different. 31, the South Locomotive and Xugong initial use of Carter chassis. And they claim to be imported cards. Of course, Carter chassis is also made in China (Xuzhou production? It sounds like I forgot who said it. Now this point few imported Carter chassis may. Because the freight can not get through. The advantage of the Carter chassis is quality stability (that doesn't mean that all homemade chassis is not good). Standard unification. The drawback is maintenance and a high cost of maintenance. The fuel costs are substantial today. It's not a small expense either. About homemade sites. Zhonglian, 31, XCMG and CSR are developing. And the earliest development of United china. From the beginning of doing the digging, are in their own production of homemade bottom. Quality is also very pass. Xcmg. 31, recently also made homemade bottom. There seems to be some technical difficulty. South Locomotive Work late. There is news that the homemade bottom is Sichuan bonlee of CSR (non reliable).
Q:What are the hidden dangers during the construction stage of rotary drilling rig?
The rotary drilling cast-in-place pile is also divided into dry hole, soil sampling rotary pile and reverse and reverse rotation pile
Q:What happened to the black smoke from the exhaust pipe of the rotary drilling rig?
Check the injector operation, see the nozzle atomizing effect, lead to pay attention to fuel quality
Q:Rotary drilling rig when piling, the drill bit off the hole in the pile, how to fish ah?
If more than fifteen meters, a thin rope tied down with the steel wire rope is fixed on the pull. If you don't deep human, not safe, do a salvage device on the line, is a piece of steel, cut into type L, L below the horizontal slightly upwards with a point of view, with the top of the vertical wire rope L, you can then put on the bit.
Q:The advantages and disadvantages of the rotary drilling rig and impact drilling machine used in the construction of bridge bored pile foundation
Most of the hard rock formations have little pile diameter and are mostly end bearing piles. Most of them are made of impact drilling. Some of them are excavated by hand, and the small hole is short. The majority of bridge piles are impacted. Encountered complex formations, the pile length is less than 40 meters, the most reliable is the use of impact drilling. A look at geology, two to see the quality, or positive and negative cycle drilling, good quality of the hole, steel dragon protection layer can guarantee
Q:How many times a day will the drilling machine be used?
It depends on the geological soil, as well as the diameter and depth of the pile.
