Its chassis is customized according to the construction requirement of the tunnel applying the idea of platformization development by the senior engineer specially designing Dongfeng chassis. The front and rear axles are both strengthened, and its spare parts have the high interchangeability with that of Dongfeng automobile, which is easy for maintenance. Four-cylinder diesel engine is adopted, with strong power. Considering the road condition in the construction site is complicated, hydraulic power steering is adopted in the steering system, and air-cut brake is adopted in braking system, 7.50-16 tire is equipped, which makes steering more flexible and convenient, parking brake safe and reliable, and makes it possible to adapt for the road conditions in different construction sites.

Performance Features:

  1. The feeding hopper works with the lifting hopper coordinately and synchronously, realizing continuous feeding, and the spraying amount per hour can reach 14m3, improving the work efficiency.
  2. The dry-mix shotcrete machine can slide easily in the track, and the feeding hopper is lifted by hydraulic control, lowering the labor intensity of maintainers.
  3. Four hydraulic legs make working of equipment steady, firm and safe,  which is more suitable for construction at construction site.
  4. The oil pump will stop working automatically when the lifting hopper is lifted to the specified height, which can not only prolong the service life of the oil pump, but also can reduce the oil consumption, saving the cost.
  5. The discharging outlet of the feeding hopper can be open and closed easily, the discharging amount can be adjusted according to the guniting amount coming from the dry-mix shotcrete machine, saving the hand regulation.
  6. The design of the accelerating agent self-feeding device is unique and reasonable, and feeding is continuous and homogeneous, with stepless speed regulation, reducing the labor cost.
  7. The accelerating-agent feeding station is set additionally, which makes feeding not only relaxed but also safe.
  8. The working switches are set on each side of the machine, more convenient for operation.
