TR250D Rotary Drilling Rigs PLC Controller  For Deep Hole Drilling 

Basic Information:

TR250D rotary dilling rig is new designed self-erecting rig mounted on original Caterpillar 336D base,adopts advanced hydraulic loading back technology, integrates advanced electronic control technology, which makes the whole performance of TR250D rotary drilling rig reach advanced world standards.

TR250D rotary drilling rig is specially designed to suit the following applications.
1. Dilling with telescopic friction or interlocking kelly bar - standard supply.
2. Drilling cased bore piles ( casing driven by rotary head or optionally by casing oscillator).

3. CFA Piles by means of continue auger.
4. Either crowd winch system or hydraulic crowd cylinder system;
5. Displacement piles.
6. Soil -mixing.

Main Features:

1. Retractable original CAT 336D chassis with EFI turbocharged engine ensures the stability of the whole machine meet the performance on various applications and construction environment.

Advanced main pump adopted negative flow constant power variable automatic control, which can realize the optimal matching in the load and the output power of engine.

Width of crawler can be adjusted between 3000 and 4300mm.

Counterweight moved back wards increases the stability and reliability.

2. The key components of the hydraulic system adopts Caterpillar hydraulic system as the maincontrol circuit and the pilot control circuit. With the advanced loading back technology, the flow can be distributed to each part of the system according to needs, which achieves better match in
various working conditions.

Pilot control makes the operation flexible, comfortable, exact and safe. Various kinds of hydraulic elements adopted world famous brand, such as Rexroth, Parker, etc. ensure the hydraulic system high reliability.

Each operating devices adopt high pressure design; the max pressure is 35MPa, which can achieve high power and full load work.

3. Electric systems are from Pal-Fin auto-control, optimal design of electric control system improves the control accuracy and the feed back speed. Equipped advanced automatic switch of manual control and auto control, the electronic leveling device can monitor and adjust the mast
automatically, and guarantee a verticality condition during operation.

4. TR250D has separated auxiliary winch collocated on the mast from triangle parts, good view and maintenance more convenient. The main winch has highlights of touch-bottom protection, priority control and fast line speed, which can greatly increase main winch releasing speed and decrease ineffective working time.

5. Compacted Parallelogram structure reduces the length and height of the whole machine, thus reduce the machine's requirement on the work space, easy transportation.

6. TR250D adopts professional rotary head equipped BONFIGL .IOLI or Rexroth reducer, and REXROTH or LINDE motor, and rotary head available in three dilling modes-standard, low speed and big torque or high speed and small torque; spin-off is optional.

7. Heavy damping spring on the base of multilevel shock absorption design , which ensures greater safety of operation.

8. The special lubricating system makes sure that the rig can work in high or low temperature environment,and effectively prolongs rotary head's service life.

9. More reasonable depth measuring device.

10. The newest designed winch drum structure is to avoid steel wire rope tangling and lengthen the service life of steel wire rope.

11. A large-space soundproofed cabin with high-power air condition and luxurious damping seat, provides driver high-comfort and pleasured working environment. At two side, there are very convenient and humanization-designed operating joystick, Touch screen and monitor show the parameters of system,includes warning device for abnormal situation. The pressure gage can also provide more intuitive working condition for the operating driver. It has the pre-automatic detection function before starting the whole machine.

12. Various safety equipments provide comprehensive protection.

Standard Equipment:

1. Working speed Rotary head as standard configuration type ( High speed rotary head as optional)

2. Winch controlled free-fall type
3. Main and auxiliary winch with special grooving
4. Hoist limit switch on main and axiliary winches
5. Swivel for main rope
6. Pivoted anchor points for main rope

Measuring And Control Equipment:

1. PLC control system, colorful LCD display
2. Display of fault messages as plain text
3. Mast inclination measurement on XY axes( digital/analog display)
4. Automatic vertical alignment of mast
5. Depth measuring device on main winch
