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.
