Crawler Hydraulic Drilling Rig 92Kw 4000-8000Nm for Water Wells

>> Products Description

The CWD400T is a high-performance, fully hydraulic crawler-mounted water well drilling rig designed for multi-functional deep drilling tasks in complex and varied geological environments.
Its rugged track-mounted chassis and hydraulic-driven system deliver superior mobility, enhanced operational control, and unmatched adaptability to diverse terrains and drilling conditions. The CWD400T supports both mud rotary drilling for soft and unconsolidated formations and air DTH (Down-the-Hole) hammer drilling for hard rock.

>> Features

Dual Drilling Functionality – Air DTH and Mud Drilling
The CWD400T supports two drilling techniques: 

Mud Drilling: Uses a BW450 mud pump and slurry for hole flushing in clay and sandy soils. Ideal for soft to medium formations.

DTH Hammer Drilling: Employs high-pressure air and a DTH hammer to penetrate hard rock layers.

Hydraulic System – Full Control and Efficiency
The drilling rig is completely hydraulically operated, offering:

Smooth, precise control of the drill system and all auxiliary movements

Independent control of feed, hoisting, and rotation systems

Centralized console for convenient, ergonomic operation

Hydraulic landing legs and tower lift for quick setup and stability

High-Performance Engine
Engine: YUCHAI 6-cylinder diesel engine

Rated Power: 92 kW

Cooling: Water-cooled system ensures long-term reliability and thermal stability

Drive Type: Full hydraulic transmission with transfer case and clutch system for optimal power distribution

Structural and Operational Advantages
Crawler Chassis: Ensures excellent off-road performance and adaptability to tough terrains such as mountains, deserts, and wetlands

Hydraulic Winch: Integrated for lifting casings and heavy tools

Optional Generator: Supports night operations or welding requirements

Guide Dumping, Boom Lift, and Boom Swing: Enhances operational flexibility and ease of positioning

Compact and Mobile Design
Despite its capacity and robust build, the CWD400T maintains a compact transportation dimension:

Transport Size: 5760 x 1850 x 2440 mm

Working Size: 3940 x 2890 x 9430 mm

Weight: 8.5 tons

This ensures it can be easily transported and deployed even in remote or logistically challenging regions.
