Product Description
The CWD450T crawler water well drilling rig is a high-performance,
multi-functional drilling solution designed for water well drilling
up to 450 meters in depth. Compatible with both DTH (Down-the-Hole)
and mud drilling, it is engineered to handle all geological
formations with efficiency and reliability.
Equipped with four hydraulically telescopic high-support legs and
an integrated leveling system, the rig maintains excellent
stability during operation. The telescopic mast provides a 6,600 mm
feeding stroke, allowing efficient drilling progress. Its advanced
rotary head supports dual-speed rotation (70/140 rpm) and fast/slow
lifting and lowering, ensuring both power and precision in a wide
range of drilling conditions.
For enhanced operational safety and productivity, the CWD450T
includes a hydraulic wrench for quick and safe drill rod handling.
The crawler chassis offers mobility across various terrains, and
the operator can control rig movement directly from the platform at
speeds up to 2.5 km/h.
The 103 kW Weichai engine, combined with a robust mechanical
structure, provides consistent performance even under demanding
field conditions, making the CWD450T an ideal choice for
professional drilling contractors.
Key Features
Powerful 450-Meter Drilling Capability
Designed for deep water well drilling, capable of reaching 450
meters while adapting to all geological conditions.
Dual Drilling Modes: DTH & Mud
Supports both Down-the-Hole hammer drilling and mud rotary
drilling, enabling flexible operation across diverse formations.
High Stability & Strong Structural Design
Four hydraulic telescopic high-support legs and an integrated
leveling system ensure stable and safe drilling even on uneven
ground
Efficient Operation With Long Feeding Stroke
The telescopic mast provides a 6.6-meter feeding stroke, paired
with dual-speed rotary control for smooth and efficient drilling
performance.
Safe & Easy Rod Handling
A built-in hydraulic wrench simplifies drill rod replacement and
enhances safety, reducing labor intensity and downtime.
Applications
- Water Well Drilling: Perfect for drilling village water wells, agricultural irrigation
wells, and industrial supply wells in both urban and rural
settings.
- Geothermal Exploration: Ideal for drilling geothermal heat extraction wells in green
energy projects, supporting residential, commercial, and municipal
heating systems.
- Civil Engineering Foundations: Used for piling and foundation holes in infrastructure projects
such as bridges, buildings, wind farms, and transmission towers.
- Geological and Mineral Exploration: Collects core samples and performs borehole testing for
understanding subsurface structure and mineral deposits.
- National Defense and Disaster Relief: Capable of quickly establishing deep wells in defense posts or
emergency operations where water access is critical.
