JDL-350 Portable Water Well Drilling Rig Machine / SPT Gold Mining Core Sample Drilling Rig
Main Features
1. JDL-350 mechanical top drive drilling rig is a kind of drilling and equipment that integrates the functions of water drill and air drill.
2. It adopts a 5-speed manual gearbox, with a wide speed change range, sensitive and convenient forward and reverse switching,and higher transmission efficiency than hydraulic power transmission. Double the power consumption, greatly reduce the power consumption, more efficient and energy-saving.
3. It solves the problems of difficult air DTH drilling in soil layers and lowconstruction efficiency of rotary drilling rigs in hard rock layers, gravel and pebble layers.
