Versatile YDL-280 Water Well Drilling Rig for Deep Boreholes with
Multi-Method Capability
Comprehensive Introduction to the YDL-280 Series Water Well
Drilling Rig
The YDL-280 series water well drilling rig, including both the
YDL-280D (electric motor) and YDL-280C (diesel engine) variants, is
a state-of-the-art hydraulic crawler drilling rig engineered for
efficient and versatile borehole construction. Designed to perform
across a wide range of drilling applications, this rig excels in
complex geology, harsh conditions, and diverse site requirements.
1. Outstanding Drilling Capabilities
The rig supports a drilling depth of up to 280 meters and a hole
diameter ranging from 150 to 350 mm, making it suitable for water
well drilling, geothermal heating wells, dewatering holes, and
foundation anchoring. Whether in hard rock, loose soil, or mixed
formations, it ensures high penetration rates and reliable
performance.
Its maximum rotary torque of 12,000 Nm, combined with a
hydraulically driven power head and mechanical-hydraulic dual-speed
control, enables operators to adapt to various drilling
technologies such as:
2. Efficient Feed and Lifting System
The rig’s 3.4-meter power head stroke allows the use of 3-meter
long drill rods in a single pass, improving operational efficiency
and reducing non-productive time. The maximum lifting force of 19.6
tons supports casing extraction and deep borehole operations. The
auto breakout system reduces operator effort and enhances safety
during rod handling.
3. Precision, Stability, and Adaptability
A 0.9-meter feed frame (thrust beam) mounted under the mast helps
push the drilling platform directly to the borehole entrance and
ensures precise positioning. The mast tilt angle of –5° to 90°
supports vertical and inclined drilling.
Additionally, the telescopic buffer spindle protects drill rods by
absorbing shock during collaring and reduces wear on the thread
connection during breakout.
4. Advanced Control and Safety Systems
Equipped with a hydraulic chuck and rod holder, the rig simplifies
make-and-break operations and increases time efficiency. The
built-in guide system at the borehole collar further stabilizes the
drill string and ensures precise, reliable drilling progress.
For added safety and convenience, the rig includes a 1.5-ton winch
for handling tools and a platform-mounted hydraulic manipulator
(optional) to aid inclined hole operations.
5. Strong Mobility and Transport Flexibility
Mounted on a robust crawler chassis, the YDL-280 rig is easily
relocated on rough terrain. Optional steel or engineering rubber
tracks allow operation both off-road and in urban environments. The
addition of four long-stroke hydraulic outriggers (1700 mm travel)
enables the rig to self-load onto transport vehicles without
cranes.
6. Reliable Hydraulic System and Power Options
The rig’s hydraulic system uses top-tier domestic and imported
components, ensuring long lifespan, stable performance, and low
maintenance. Power can be configured to suit customer preferences:
Auxiliary equipment such as mud pumps, booster pumps, or air
compressors can be powered by electric, diesel, or hydraulic
drives.
7. Customizable and User-Oriented Design
Users can request short or long mast options, tailored for specific
drilling depths and transport conditions. The automatic rotation
platform allows flexible directional control, and optional
hydraulic telescopic legs increase operational stability.
Whether in urban water source development or remote field drilling,
the YDL-280’s modular structure and customization options make it
an ideal choice for contractors worldwide.
