Top drive drilling rigs employ mechanical drive systems for accurate, efficient drilling operations. Supporting water well drilling to 500 meters and wireline coring to 800 meters, the top drive drilling system generate 9,800-12,000 N∙m of torque through 5-speed transmissions. These top drive rigs effectively handle stratified formations including gravel and weathered rock, making them ideal for geothermal drilling and deep groundwater exploration projects.
