  Crawler Mounted Drill Rig Supplier  shares this article for you. Features of crawler rig This type of rig is suitable for more complex areas, with the strong climbing ability and strong rock input ability. The disadvantage is that the equipment itself is very heavy, and the crawler chassis itself has poor performance. It is necessary to rely on large pallet truck transportation and supporting vehicle transfer support equipment and supporting equipment for the transition. The transportation cost of the equipment is high, the road conditions and the turning radius are relatively high during the transportation process, and the local coordination is difficult. According to on-site usage statistics, pallet trucks (transport rotary drills), cranes (suspended drill rods), and semi-trailers (transport drill rods) are required for the transfer of crawler rigs. The removal of drill rods, drill bits, equipment handling trucks, road transport, drill rod installation, drill bits, etc. takes a lon

  DTH drilling rig supplier  introduces the main domestic drilling equipment according to the widely used classification method. 1.2.1 Split drilling rig The split crawler rig with traditional crawler structure has always been the main type of drill rig in coal mines. Even in the situation where crawler rigs are commonly used, split rigs still occupy a large proportion, which is caused by the special restricted underground tunnel conditions. decided. According to the characteristics of underground drilling construction technology and the requirements of the basic performance parameters and structural form of the drilling rig, the split drilling rig is divided into three parts: the main machine, the console, and the pump station. The drilling rig generally adopts a valve-controlled hydraulic system and domestic hydraulic components. According to the needs of the hydraulic function circuit, it can realize shunting, merging, and special hydraulic linkage control to meet the requirements o

  DTH Drilling Rig Supplier  shares this article for you. The geological conditions of coal fields are complex, and natural disasters such as gas, water damage, and high ground stress severely restrict coal mine safety production. Underground coal mine drilling construction is the most effective and direct means for comprehensive gas control, mine water hazard prevention, detection of hidden disaster-causing factors, and prevention of rockburst pressure. It is an important geological support technology for coal mine safe and efficient mining. Due to the narrow space of coal mine tunnels and the explosion-proof requirements under special environmental conditions, conventional non-explosion-proof ground drilling equipment and instruments cannot be used directly downhole, and the requirements for underground transportation, ventilation, water supply, and electricity are also directly related to the use and site of drilling equipment The construction has a great impact. The construction of
