Product Description:

OTR580D:
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 not use rotary drilling rig instead of manual digging pile?
Rotary drilling rig deviation is too large, the basic holes are straight, and drill down to the following oblique error is great
Q:The relationship between rotary drilling and impact drilling and reverse circulation drilling
The main difference is the construction process. Rotary drilling rig adopts the technology of making mud, drilling bucket, rotating soil and injecting hole. Mud does not produce circulation.
Q:Why is the rotary drilling rig put into the steel cage before pouring?
Because the steel bar is not properly installed first, it must be easier to put the steel cage first. The CFA method is very special, is through a hollow pipe concrete long spiral, if you pull out the long spiral after reperfusion may hole collapse, there will be holes in the soil sediment, not net, so through the middle of the air directly to the bottom of cast-in-place concrete
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: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:How to choose the drill bit of a spiral drill?
During the operation of long auger, all the personnel present must wear safety helmet. In the construction process, according to the different geological conditions, choose different bit. The spiral rotary head of long auger rig adopts mud wall protection, which is suitable for cohesive soil, silt, sand, filling soil, crushed stone soil and weathered rock stratum above the water table.
Q:What's the difference between a long auger and a rotary drill?
The difference is bigger, the long superiority is in the small caliber (600mm) pile diameter, and the gravel layer is dense, the clay layer is thicker.The advantages of rotary construction, wide range of application, high installed power.From a long-term perspective, rotary digging is better than long spiral.
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Drill pipe: the drill pipe of the rotary rig is 3 meters per section, and the section of the rotary drilling rig is telescopic. It is in place
Q:How can the drilling rod of rotary drilling rig be telescopic?
It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.
Q:How high are auger rigs and impact drills?
Impact drill is relatively short, about 3 meters ~4 meters, down to only 2 meters high.
