The Crawler Mounted Drill Rig is a dual-purpose drilling rig suitable for high-pressure rotary jetting and anchoring construction technology according to market needs. It is easy to move and move, reducing the labor intensity of construction workers. At the same time, due to the installation of the crawler chassis, the moving speed during the drilling process can be greatly improved, thereby effectively improving work efficiency.
With competitive price and timely delivery, JK Drilling sincerely hope to be your supplier and partner.
The Crawler Mounted Drilling Rigs can be configured according to different performances. The maximum output torque of the rotary drilling rig can reach N.m, and the maximum pulling force can reach 60kN. The hole can be selected from the rotary drill of the hard alloy drill bit and the impact hammer of the down-the-hole hammer. Drilling and other processes, so that it can be directly formed into holes in the majority of the formation, and immediately sprayed into piles.
What is a jet grouting pile?
The jet grouting pile is to use the rotary jet drilling machine to place the rotary jet grouting pipe and the nozzle drill in the design height of the pile bottom, and the pre-formed slurry is passed through the high-pressure generating device to obtain a huge energy of the liquid flow, and then from the nozzle of the grouting pipe side. High-speed injection, forming a highly concentrated liquid flow, directly destroying the soil. During the spraying process, the drill pipe is rotated while lifting, so that the slurry and the soil are fully stirred and mixed to form a columnar solid body of a certain diameter in the soil. So that the foundation is reinforced. The construction is generally divided into two work processes, namely, first drilling and then spraying, then drilling down, and then lifting the mixing to ensure the proportion and quality of the slurry per meter.
The crawler pneumatic drill rig is a kind of light walking crawler with deep hole drilling rig powered by compressed air. It is suitable for the construction of water exploration, gas exploration and gas drainage holes in underground coal mines. The crawler pneumatic drill rig uses compressed air as the power source, which is safe and convenient for it to walk. In addition, what other advantages are worth using in the mine?

1. The track of the crawler pneumatic drill rig can rotate automatically, and the drilling range is 360° horizontally and 360° vertically.
2. The crawler pneumatic drill rig can reach out of the car body for drilling, and it is easy to cross the belt support machine and other coal mine working devices for the drilling operation.
3. With its small external size, it can walk freely in a 0.8-meter tunnel. The high-power walking system is equipped with a vehicle-mounted drill pipe space. The feed of the drilling rig adopts an independent motor, so the feed speed is easy to control.
4. This type of industrial drilling equipment has a structure of the muffler that minimizes noise, which can effectively improve your working environment. The crawler pneumatic drill rig has a split structure for supporting the column to facilitate underground transportation through the air gate. The whole machine is equipped with a large-capacity oil mist device, thus it can be used for a long time once being filled up.
5. The crawler pneumatic drill rig is equipped with different drilling tools to realize the construction of exploration and relief holes, and the matching large-diameter drill bit has an obvious effect on drilling pressure relief holes. it pioneers in its drilling diameter, drilling depth, etc. In the drilling construction of any soft and hard medium, the bit cutting terminal always maintains a power output of more than 20kW and is more efficient than the similar products in the market.
