Hydraulic piling/drilling rig
The hydraulic drilling rig is mounted on CATERPILLAR turret and has been specially designed for suiting the very deep bored piles stabilized by drilling fluid or dry hole, and meeting the needs of various geology, such as hardpan, gravel, pebble bed, medium decomposed rock, and mud stone.
1.Undercarriage with expandable and removable tracks by means of hydraulic cylinders, which guarantee exception stability 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 is 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, design for an safety and comfort with Sound proof and air conditioner.
10. Electronic controlling system is an innovative system, developed by Osaint, which controls and monitors the operation of the machine. To ease operation the system is controlled by a touch screen located in the cab. The system’s function is to enable the machine 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.
