Crawler Mounted Drilling Rig  is used more and more widely in grouting operation. Grouting reinforcement is mostly open-air operation. This paper mainly discusses how to choose the model of crawler-type down-the-hole drilling rig. The following principles should be adhered to when choosing. (1) Applicability in production In order to meet the needs of Engineering construction, the selected drilling rigs should be rationally allocated according to the construction tasks undertaken by enterprises under normal conditions, and the scope of application of drilling rigs should be fully considered. They should not only meet the current construction needs, but also take into account the needs of drilling rigs under other production conditions in the future. Only the drilling rigs with strong applicability in production can better show their investment effects. (2) Advanced Technology While meeting the production needs, it is necessary to maintain the advanced performance indicators, w

Before the production of the  Water Well Drill Rig , it is necessary to carry out preparatory work and lay the basic work to ensure the stable and efficient production of the water drilling rig. The production preparation work of the water well drilling rig is divided into several steps, namely: determining the well position, repairing the road, leveling the site around the wellhead, laying the foundation, and installing. These preparations are not only necessary, but also necessary for production operations. The main function of the site around the wellhead is to level a site around the wellhead, so that the well can be better constructed and produced. The size of the well site depends on the size of the well. Large-scale wells need to be drilled. For larger sites, smaller well rigs require smaller site fixes to determine the position of the well rig or the bottom of the well, based on geological or production requirements. The foundation is to make the water well drilling rig better

Our new machine all in one type JK830  All In One DTH Automatic Drill Rig , comfortable cabin creates a very excellent environment for operator, automatic pipe exchanger saves much more labour, air compressor built-in makes its moving conveniently, dust collection system ensures a clean environment. 

The automatic crawler rig has low operating costs and an ergonomic design. In addition, what are the characteristics of the crawler drill? Let  Crawler Mounted Drill Rig Supplier  give you a brief introduction. 1. The crawler drill has a steel crawler travel mechanism, which makes the whole machine easy to move. Because it is a steel crawler, it is very wear-resistant, so it is convenient for the construction of the drill in the city. 2. The  Crawler Mounted Drilling Rigs  has hydraulic pressure feeding mechanism to improve drilling efficiency. 3. The crawler drill is equipped with the upper ball clamp mechanism instead of the chuck, which can implement the non-stop bar, high work efficiency, convenient operation, safe and reliable. 4. The crawler drill is equipped with a pressure gauge at the bottom of the hole to indicate the pressure, which is convenient for grasping the situation inside the hole. 5. The crawler-type drilling rig is hydraulically operated, which is conven
