High Performance Torque Rotary Drilling Rig Machine TR210D: Top-of-the-line drilling rig for high torque applications

TR210D Rotary drilling rig is mainly used in the construction of civil and bridge engineering, it adopts advanced intelligent electronic control system and loading sensing type pilot control hydraulic system, the whole machine is safe and reliable. It’s suitable for the following application; Drilling with telescopic friction or interlocking Kelly bar –standard supply; Drilling with CFA drilling system – option supply;

Technical characteristics:

1. The drilling rig can be transported without dismounting the drill pipe, which saves the logistics cost and improves the transfer efficiency, and its lower part additionally has the crawler extension and retraction functions and can fully retract to 3000mm, and fully extend to a width of 4100mm, thereby ensuring the construction stability and adapting to the construction requirements of most small construction sites.

2. The high-power Dongfeng Cummins engine is used and meets the national stage- 111 emission requirements, and has the characteristics of economy, efficiency, environmental protection, stability and so on.

3. The power heads with domestic leading brands are used with a maximum rotational speed of 33 rotations per minute, and has the characteristics of high torque, reliable performance and stable quality.

4. The hydraulic system adopts the international advanced concepts and specially designed for optimization of the rotary drilling rig. The main pump, the power head motor, the main valve, the auxiliary valve, the balance valve, the walking system, the slewing system, the pilot handle, etc. are of imported brands, and the auxiliary system uses a load-sensing system, and the flow distribution on demands is achieved.

5. All key parts of the electronic control system (display, controller, dip sensor, sounding proximity switch, etc.) are of high-end original imported components with international famous brands, the reliable aviation connector is used for the control box in order to create special domestic engineering machinery products.

6. The main and auxiliary winches are arranged on the mast to facilitate to observe the wire rope direction, the double-broken-line drum is designed and used, the drilling rig is wound with multi-layer wire ropes for smooth releasing, so that the wear of wire ropes is effectively reduced, and the service life of wire ropes is effectively improved.
