Underground Concrete mixer truck is mainly used for the concrete transportation in the hardening of roadway surface

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.

The Advantages comparing to other traditional old models

1. BIGGER CAPACITY: The concrete mixer truck can carry 5 cubic meters at a time, which is 2.5 times of the explosion-proof engineering truck. Therefore, when transporting the same amount of concrete, the concrete mixer truck can greatly shorten the transportation time and increase the working efficiency;

2. LOWWER FUEL CONSUMPTION: Under the same transportation volume, the fuel consumption of concrete mixer truck can be saved more than 80 liters compared with that of 100 kilometers. It greatly reduces fuel consumption and saves production cost. A kind of

3. PREVENTION of LAYERING: In the process of transportation, the concrete mixer truck always keeps the concrete in the mixing state. In the case of long-distance transportation, it effectively prevents the concrete layering or solidification phenomenon that the explosion-proof engineering truck cannot avoid. A kind of

4. EASY OPERATION: Before the concrete mixer transports, the material is discharged before the feeding, and the discharging valve can be opened directly to discharge the material, which is convenient for the operation of the operators, and it can discharge the material quantitatively to prevent excessive discharge and waste. A kind of

5. PREVENTION OF SPLASHING: The concrete mixer truck effectively prevents the concrete from splashing on the road surface due to the bumping of the road surface, which leads to the damage of the road surface of the transportation lane. A kind of

6. COMFORTABLE CAB: The cab adopts a sealed structure, which can effectively reduce the exposure of people in rainy and snowy days to freezing in winter; the cab is relatively higher than the explosion-proof engineering vehicle, and the driver’s vision is good.
