Application Scenarios
Product Description ： The Model 300 Pneumatic Crawler Drill effortlessly handles a wide range of complex geological formations. Struggling with hard rock? Switch to the pneumatic hammer for high-frequency impact that pierces straight through the rock layer. Dealing with soft, unstable ground? Activate the mud pump to stabilize the borehole walls while drilling. With a drilling depth of up to 300 meters, it is suitable for various applications, including domestic wells in rural areas, irrigation systems, and mountain drinking water projects.
Product Features： 1. Capabilities: Drilling depth of 300m; wide rotational speed range (approx. 14–500 rpm) and broad torque coverage. 2. Drilling Methods: Primarily utilizes a "water + air" combination; supports conventional rotary drilling, percussive-rotary drilling (DTH hammer), and casing-advancement techniques; features dual power heads or long-stroke designs (approx. 3.4–7m) to minimize drill rod handling and reduce the risk of borehole collapse/blockage; adaptable to loose strata, sand and gravel, clay, and bedrock/granite, offering high efficiency in mountainous terrain and hard rock formations. 3. Structure and Control: Self-propelled with rapid site-to-site mobility; typically features a crawler chassis with stabilizing outriggers and dual hydraulic pumps; minimizes auxiliary downtime (e.g., during rod handling); includes expansion interfaces for optional remote control or monitoring systems. 4. Safety and Maintenance: Power head features a floating mechanism to protect drill rod threads; casing power head doubles as a casing driver/wrench for mechanized make-up and break-out; clear layout facilitates easy maintenance and repair.
