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

Q1: Can the drilling rig be transported without disassembly?
A: Yes. The drilling rig is designed to be transported without dismounting the drill pipe, which saves logistics costs and improves overall transfer efficiency.
Q2: What are the retractable chassis dimensions of the rig?
A: The lower part has crawler extension and retraction functions. The chassis can fully retract to a width of 3000mm for narrow sites and transport, and fully extend to 4100mm to ensure construction stability.
Q3: Which engine is equipped and what are its environmental standards?
A: The rig uses a high-power Dongfeng Cummins engine, which meets national stage-III emission requirements and features economical, efficient, and stable performance.
Q4: What is the maximum torque and speed of the power heads?
A: The power heads feature domestic leading brands and deliver a maximum output torque of 210 KN.m with a maximum rotational speed of 33 rotations per minute (drilling speed ranges from 0-30 r/min).
Q5: What are the depth and diameter capabilities for drilling?
A: This drilling rig supports a maximum drilling diameter of 1500 mm and reaches a maximum drilling depth of 45/57 meters.
Q6: How does the design of the winch system improve the service life of wire ropes?
A: The main and auxiliary winches are arranged on the mast to optimize wire rope direction. Additionally, the double-broken-line drum allows multi-layer wire ropes to release smoothly, reducing wear and improving service life.
