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:Why should auger drilling be done by means of jump excavation?
According to the construction of regional geological conditions and construction requirements, the general pile drilling pile construction in the jump, has been filling into a pile of adjacent pile drilling bit, is to wait until the strength of concrete bored pile has reached more than 2.5MPa before drilling, to avoid the disturbance of bored pile adjacent construction.
Q:Attention problems of rotary drilling rig
1 remove the inspection cover near the base of the boom.2. Remove bolts, washers, lower cover and gasket.3, check the gasket, if there is obvious damage, should replace the gasket.4. Check the grease surface. Grease should be evenly distributed at the bottom of the tank.5. Check whether the grease is contaminated or discolored.6 grease should be replaced if the grease is contaminated or discolored by water.7. Lift the boom and transfer the upper structure to the 1/4 ring.8 repeat the procedure 7 1/4 cycles.
Q:How can the drilling rod of rotary drilling rig be telescopic?
The drill rod of the rotary drilling machine is now extended from the lower part of the hoist, the steel wire extends out, and the hoisting rope is retracted. But some rotary drills can be extended either by a crane or by gravity.
Q:Xugong 220 rotary drilling rig operation instructions who help find
Rotary drilling rig is suitable for sand and clay, silty soil layer construction, bored pile, continuous wall, foundation reinforcement has been widely used in various foundation foundation construction, mainly for municipal, road bridges, industrial and civil buildings and other infrastructure construction. The rated power of rotary drilling machine is generally 125-450kW, power output torque is 120-400kNm, the maximum diameter of the hole can reach 1.5-3m, the maximum hole depth is 60-90m, which can meet the requirements of various large-scale infrastructure construction.
Q:How can we not drill the rod and drill the rod?
Resolvent:1. Remove the drill pipe and remove the foreign objects.2, repair wear and deformation parts.3, open the drill rod, plastic alignment.4, adjust the operation method.
Q:What's the price of the 31 sr630rc8 rotary drilling rig?
31 drilling rigs are good in domestic brands.
Q:Rotary drilling rig deep hole Doumen difficulties what happened?
It can not be completed by simple drilling technology (rotary drilling rig does not need gas, water circulation is not needed, and soil is imported by spiral sheet, which we call simple drilling process)
Q:Why not use rotary drilling rig instead of manual digging pile?
It is time the project team in general when digging and construction engineering team can.
Q:If you have a project, will you make money from the auger rig?
Generally very profitable! If you need a worker, you can contact the little soldier or me
Q:220 rotary drilling rig can adapt to what kind of soil?
Sand soil, cohesive soil, silty soil layer, different manufacturers will also have different performance, but also into the rock capacity
