JC4.5 Underground Concrete mixing truck for Coal Mine
Underground Concrete mixing truck for coal mine is mainly used for the concrete transportation in the hardening of roadway surface of underground coal mine.
At present, the technology of the concrete mixer truck on the ground has been fully mature on the market, and the products are diversified and applied to many industries and projects, which can greatly improve the working efficiency. There are a series of advantages. However, in the coal industry, the transportation mode of the underground concrete still stays in the original state of the open tipper truck transportation mode, which is the transportation party It is not only small in transportation volume and low in efficiency, but also easy to splash and layer concrete in long-distance transportation. It also needs a lot of manpower assistance. However, the use of underground concrete mixer truck is still blank in the domestic and global coal industry.
Based on this premise, our company, together with Shenhua Shendong Group Research Institute, has jointly developed an explosion-proof concrete mixer truck suitable for underground coal mines. Once this product is published, it is widely concerned and welcomed. At present, the technology of this product has been fully mature and used in many coal mines in Shanxi, Shaanxi and Inner Mongolia, and it has been well appraised.
At present, our company is developing the following four types of products with different specifications according to the actual environment of unused coal mines and the requirements of users.
exhaust system;
Features
1. Closed cab, comfortable and safe driving, wide vision;
2. Explosion proof electric control box, constantly monitoring the “health” of the whole vehicle;
3. Imported plunger pump, gear pump, the “second heart” of the whole vehicle, with more stable performance;
4. Equipped with cleaning device, it is convenient to clean the tank and other parts anytime and anywhere;
5. Imported motor reducer, roller drive device;
6. The self-developed rotary sealing device at the tank mouth enables the tank body to load more concrete;
7. The monitoring console, various instruments and monitoring displays make it more convenient for the driver to monitor the vehicle status directly;
8. it is equipped with reversing monitoring and alarm device, which is convenient for the driver to reverse in underground or narrow environment and ensures the safety of construction personnel.
