Shotcrete Sprayer

The shotcrete sprayer is a concrete spraying machine unit that integrates spraying and feeding. It is mainly used in engineering construction in the fields of railway highway tunnels, water conservancy, and hydropower, subways, mine roadways, military installations, various underground construction, and emergency rescue. The basic process is to use hydraulic pressure to transport the pre-mixed concrete to the spray gun through the pipeline, connect compressed air and quick setting agent to the spray gun, and then spray the concrete to the spray surface at high speed to form the concrete support after rapid setting and hardening floor. With the large-scale development of modern engineering construction, the market demand for shotcrete trucks has rapidly expanded in recent years, and the requirements for construction efficiency have become higher and higher. The construction efficiency is not only reflected in the process of spraying, but also in the flexibility of the product.

Double Hopper Automatic Feeding Shotcrete Sprayer Features:

  1. Double-bucket design, front hopper unloading, and rear hopper feeding, to ensure that the spraying machine works continuously for 24 hours!
  2. The design capacity of the upper hopper is 6 square meters, and the front hopper is 2 square meters, which is convenient for vehicle scheduling!
  3. The chassis is modified by the crane chassis of a well-known domestic automobile manufacturer. The double-layer beams have a large carrying capacity and are more suitable for various field operations!
  4. Dual power design, the hydraulic outrigger, and hopper can be directly operated by the vehicle power output without power connection!
  5. The hopper lifting and outriggers all use hydraulic power, with large strength, stable operation, and convenient and quick operation handle!
  6. All the frames are made of thickened profiles to ensure the rigidity of the body and never deform!
  7. The upper hopper adopts the design without a ladder, which is suitable for the unloading of various construction vehicles!
  8. The addition of a quick-setting agent adopts a vibration type, the discharge can be controlled, and the quick-setting agent can be added quantitatively.
  9. The front hopper can be turned over. When the front hopper is overturned, the spraying machine can be dismantled and repaired.
  10. The rear hopper adopts a separate vibration mode to start vibrating when the spray slurry is wet and unloading is not smooth.
  11. The control buttons of two types of shotcrete machines are located on both sides of the machine body, which is convenient for the operators of each shotcrete machine.
  12. The minimum ground clearance is 350mm! Cross the tunnel trestle, climb the hill and pass the invincible direction!

Lifting Spray Gun

The hydraulic automatic feeding unit for shotcrete is a new product developed by our company according to the needs of national infrastructure construction. This product can be used for two shotcrete machines at the same time. This product can be widely used in the construction of large-span tunnels. It has the characteristics of high efficiency and humanization. It replaces the traditional manual feeding construction mode, saves the labor to the greatest extent, avoids the harm of construction workers caused by manual feeding dust, and avoids it avoids the waste caused by the material residue on the unhardened working surface when loading manually. This product has a number of national patents, advanced technology, perfect functions, simple operation, easy maintenance, no wearing parts, and can minimize the construction cost.
