JDL-5 Mechanical Top Drive Water and Air Dual Purpose Drilling Rig

1. Brief introduction of JDL-5 mechanical top drive water and air dual purpose drilling rig

JDL-5 drilling rig is a mechanical top-drive water well drilling equipment that can be drilled at 75-90° and integrates water drilling and air drilling. It solves the problems of difficult drilling with air DTH hammer in soil layer and low construction efficiency of mud drilling in hard rock layer, gravel and pebble layer. The water-air dual-purpose drilling rig is suitable for various formations and has high drilling efficiency.

2. Features of JDL-5 mechanical top drive water and air dual purpose drilling rig

（1） Equipped with hydraulic steel crawler, strong off-road capability;

（2） Equipped with 4 hydraulic square tube high outriggers for auxiliary support and getting on and off;

（3） The left and right sides of the drilling rig are equipped with drill pipe racks and foot pedals, and the design is user-friendly;

（4） The front end of the drilling rig is equipped with an auxiliary rod unloading cylinder, which is convenient for loosening the drill rod;

（5） The drilling rig uses dual oil pumps to supply oil, and the hydraulic system uses the technology of shunt and confluence, and the power head rises and falls rapidly;

（6） The hydraulic oil pump and the power are directly connected by the coupling, and the drilling rig can climb and move powerfully;

（7） The 5-speed manual gearbox is adopted, with a wide speed change range, sensitive and convenient forward and reverse switching, the transmission efficiency is doubled compared with the hydraulic transmission, the power consumption is greatly reduced, and it is more efficient and energy-saving.
