PRODUCT DESCRIPTION
>> Characteristics
The JCM400 is a fully hydraulic top-drive rotary crawler drilling rig designed for versatile applications, including tunnel pipe roofing support holes, pilot survey holes, urban deep foundation pit anchoring, grouting reinforcement, slope stabilization (large-tonnage prestressed anchor holes), geothermal heat pump well drilling, and small-to-medium foundation pile holes, water wells, and blast holes.
Fully Hydraulic Control: Adjustable rotation speed, torque, feed pressure, and lifting speed for optimal performance across different drilling conditions.
Top-Drive System: Integrated impact, rotation, and feed/lift mechanisms enable efficient rod handling and reduce auxiliary time. Supports pipe-following drilling.
High Efficiency: Compatible with multiple drilling techniques (DTH, air reverse circulation, auger, etc.), ensuring fast penetration and lower operational costs.
Crawler Mobility: High-leg design for easy loading/unloading without a crane. Crawler undercarriage ensures stability on muddy or uneven terrain (20° gradeability).
