Product card summary: A medium-capacity multi-method drilling rig with 600 m NQ capacity, 10,500 N·m torque, and a 3,500 mm feed stroke. It is configured for mud drilling, DTH hammer drilling, and casing-following work in mixed formations.
Product detail page introduction: The JDL-350 series increases drilling depth, lifting force, and feed stroke while retaining the flexible drilling methods of the JDL platform. Its mechanical top-drive power head delivers high-speed rotation for suitable formations and strong torque for demanding conditions. The 3.5 m stroke reduces frequent rod-handling cycles, while the dual-pump hydraulic system supports efficient lifting and lowering operations.
