Application of Water Drilling Rig Machine: The drill is suitable for census exploration, geophysical exploration, road and building exploration and blasting drilling and other drilling projects. Can be based on the different layers of alloy, grit and steel drill bits for drilling. Can drill 2-9 level of sandy clay and bedrock, Rated drilling depth 100m, the deepest shall not exceed 120m, Nominal opening diameter of 110mm, the max. allowable opening diameter of 130mm, the final hole diameter of 75mm, drilling depth according to formation conditions. Advantage OF ST-100 Water drilling rig machine: 1. With hydraulic automatic feeding machanism to improve drilling efficiency, reduce labor intensity. 2. The use of ball-type clamping mechanism instead of the chuck can be implemented without downtime bat, easy to operate, safe and reliable. 3. With a pressure gauge indicating the bottom of the hole, easy to grasp the situation inside the hole 4. Handle focus, the operator side. 5. Compact structure, rigs, pumps and diesel engines are installed on the same bas, occupying a small venue. 6. Light weight. strong decomposition, easy to relocate, suitable for plain or mountain work.
