1. Dual drilling modes in one machine： Combining mud and air (DTH) drilling, the JDL-350 works across diverse formations, eliminating the need for a second rig and maximizing your investment. 2. Rapid mobility and fast setup： Hydraulic steel tracks, four hydraulic outriggers, and a foldable auxiliary tower (lifting two 3 m drill rods at once) cut on-site leveling and handling time significantly. 3. Higher efficiency, lower labor：The AMT automatic transmission and dual oil pumps with split-flow/merge technology speed up power-head travel and shifting, boosting productivity while reducing operator effort.

Product Description： The YGDQ-350 is a top drive core drilling machine engineered as a dual-purpose platform that combines mud (water) drilling and air (DTH hammer) drilling in a single machine. By integrating both drilling methods, it resolves the common failure of air hammers in loose soil layers and overcomes the low efficiency of conventional mud drilling. The rig adapts to a wide range of formations, from loose topsoil to hard bedrock (hardness F6–20), delivering a drilling capacity of up to 530 m (Φ42 mud), 600 m (NQ wireline coring), and 350 m air drilling depth. Powered by a 58 kW YN33 diesel engine with a max torque of 10,500 N·m, it combines high mobility, fast setup, and energy-efficient core drilling — an ideal solution for efficient geological exploration and water-well drilling.
Product Features: 1. Strong off-road capability： Hydraulic steel tracks with a 20°–30° climbing angle ensure reliable movement on rugged terrain. 2. Convenient on-site leveling：Four hydraulic square-tube outriggers allow quick leveling and dramatically save loading/unloading costs. 3. Operator-friendly design： Drill rod holders and foot pedals on both left and right sides make handling safer and more ergonomic. 4. Easy rod handling：A front auxiliary rod unloading cylinder simplifies loosening and breaking the drill rods. 5. Direct power transfer:：The hydraulic oil pump is directly coupled to the engine via a universal shaft, delivering stronger climbing and traveling force.
