Company profile:
1. Hunan Osaint Heavy Industries co.,LTD., the modernized manufacturer of piling machinery in China, which is specialized in producing high reliable quality piling machines covering entire range of rotary drilling rigs with independent intellectual property rights and dozens of patent.
2. OSAINT rises rapidly by its core competitiveness through cooperating with well-known european R&D institute, which guarantee OSAINT becomes a top brand in China and famous brand in aboard.
3. Products of OSAINT has fully certified by CE, which has been directly verified by EU authority centre, and management system of OSAINT is certified by ISO9001:2000 etc.
LEAN MANUFACTURE
OSAINT regards achievement of the lean manufacturing as the basement of enterprise development. A special manufacturing euipments and tools are pay a key role for proving strong fabrication ability to guarantee the perfect present of super-excellent design.
ACCURATE DESIGN
Developed from cooperation with the famous Academy of university in China and with well-know European R&D institute, the R&D center of OSAINT has currently a staff of 100 well trained and experienced engineers and research fellows. Attributed to the modern design tools, which include Dynamic Moderling software, 3D Assembly Simulation, Engineering Analysis program, the drilling rig of OSAINT has a reputation of world first-class quality.
Features:
1. Undercarriage with expandable and removable tracks by means of hydraulic cylinders, which 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.Turret CATERPILLAR Tier 3, disel engine and sound proofed canopy, mounted on a 360 degree slew ring. The CAT hydraulic system is made in order to exploit the power of the diesel to the most and inroder to guarantee maximum performance.
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.
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.
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. Available with friction or mechanical locking type.
9.Capterlillar turret.
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 system ensures the main pumps and Disel engine to work at their most effective and productive stages.
