The product of the perforation rigs describes the submersible engineering rigs as submersible electric revolving rigs, which are the ideal poaching machinery for drilling plumes. They can also be used in groups for engineering works such as continuous underground walls and boreholes. It applies to multiple layers of boreholes such as sludge, clay, gravel layers, weather shale, etc. It is widely used for basic works such as construction, transport, water, electricity and port. The perforation rigs are used mainly for open drilling or mines, as well as for open drilling operations such as construction, hydroelectric engineering, road rail and military engineering. It is one of the main piercing equipment for small and medium-sized open mines. The perforation drills are at altitudes below 3,000 m and can be used at temperatures ranging from -35°c to 40°c under climatic conditions. An oscillation or vertical hole in 200 mm aperture, usually drilled at 60°, 75° and 90° steps of 12-15 m. The performance characteristics of the perforation rigs carry their own spiral wind-cold air compressors and 315 kva electric transformers. The driver's room, which is open and bright and which uses pressure purification techniques, provides a comfortable working environment for operators. Propulsion, voltage, combined automatic propulsion. The rigs are equipped with two dry and wet dust removal systems for user selection.
