TR400D Rotary Drilling Rig With 110m Drilling Depth And 2500mm Diameter For Foundation Piling

TR400D rotary drilling ng is widely used in the field of piling construction and currently most of our customers prefer to choose for construction of cross-sea or cross-river bridges. TR400D rotary drilling rig has thecharacteristics of high stability, large pile diameter & depth and convenient transport.

TR400D Main Technical Specification:

Feature and advantages of TR400D rotary drilling rig:

1. The main winch of TR400D rotary drilling rig is driven by double motors, with double reducers and the single layer structure, which can prolong the useful life of steel wire rope and reduce working cost, at the same time ensuring the pull force and speed of the main winch.
2. TR400D rotary drilling rig adopts winch crowd system with the maximum 16m long stroke, and maximum crowd force and pull force can reach 44 Ton. Many methods of engineering can be applied well.
3. TR400D rotary drilling rig adopts Big-triangle support structure to guarantee the working stability for the drilling rig.
4. TR400D rotary drilling rig Use original CAT undercarriage and upper unit Width of crawler can be adjusted between 3900and 5500mm. Counterweight has been moved backwards and increased to improve the stability and reliability of whole machine.
5. Key units of hydraulic system use Caterpillar hydraulic systems main control circuit and pilot operated control circuit, with advanced load feedback technology, which made the flow distribute every units of the system according to need, in order to achieve the operation have the advantages of flexibility, safety, conformability and exact.
6. The pump, motor, valve, oil tube and pipe coupling are chosen from all first class parts which ensure high stability. Every units designed to high pressure-resistant ( The max pressure can reach 35mpacan work in high-powered and full load.
7. The electronic control system of TR400D rotary drilling rig applies the DC24V direct current, and PLC monitor the working condition of every unit such as starting-up and extinguishing a fire of engine, the upper rotation angle of mast, safety alarm, the drilling depth, and the failure.
8. The main parts of electronic control system are high quality and adopt advanced electronic leveling device which can switch freely between automatic state and manual state. This device monitor and control the mast to keep vertically during operation. The mast is auto controlled and monitored by the advanced manual and auto switch electronic balance device to keep its vertically, which could guarantee the vertical requirements of the piling hole effectively and achieve the humanization layout of the control and friendly Human-machine Interaction.
9. The hydraulic system is radiating independently.
10. The TR400D rotary drilling rig whole machine has proper layout to reduce counterweight: the motor, hydraulic oil tank, fuel tank and the master valve are located at the back of the slewing unit, the motor and all kinds of valves are cover by a hood, elegant appearance.
