The Crawler DTH Drilling Machine is an impressive equipment that has revolutionized stone quarrying. It is widely used in Western Europe due to the convenience and efficiency it offers.
The Crawler DTH Drilling Machine is designed to operate even in the toughest of terrains. It can easily navigate through uneven surfaces and reach the most remote parts of the quarry, ensuring that no stone is left unturned. This feature further enhances the efficiency of the machine, making it a highly reliable and sought-after tool.
The machine's convenience is another significant advantage. It is easy to set up and requires minimal manual labor, thereby reducing operational costs. Additionally, the Crawler DTH Drilling Machine is low maintenance, which means that quarry owners can enjoy a higher profitability margin.
⭐ Crawler DTH Drilling Machine – High-Performance Quarry & Mining Rig
The Crawler DTH Drilling Machine is a powerful and reliable rock-drilling solution designed for open-pit quarrying, mining, construction foundation drilling, and geotechnical engineering. Built with a high-strength crawler undercarriage and heavy-duty rotary system, this machine delivers strong penetration capability and excellent drilling efficiency even in very hard rock formations such as granite, basalt, and limestone.
This Down-the-Hole drilling machine combines hydraulic power, crawler mobility, and air-driven hammer technology, making it ideal for drilling vertical, inclined, and horizontal holes in complex working conditions.
🔶 Key Features of Crawler DTH Drilling Machine
High-torque hydraulic rotation system
Strong crawler chassis for rough terrains
Heavy-duty boom for multi-directional drilling
DTH air hammer system for fast penetration
Suitable for hard and abrasive rock
Easy operation and low labor requirement
High productivity and lower drilling cost
🔶 Working Principle
The Crawler DTH drill uses a Down-the-Hole hammer powered by compressed air. Unlike top-hammer drilling, DTH places the hammer at the bottom of the hole, improving energy transfer and allowing faster drilling speed and less power loss.
This makes it extremely efficient for deep drilling and hard rock conditions.
🔶 Typical Drilling Specifications (Depending on model)
Drilling diameter: 90–200mm
Drilling depth: 20–40 meters per pass
Rotary torque: High torque hydraulic rotation
Air consumption: (varies by hammer size)
Working pressure: 0.7–1.6 MPa
🔶 Application Fields
