Typical recommendation For high-boom wet spraying machines: Air compressor displacement is usually ≥ 8–10 m³/min Working pressure commonly 0.6–0.8 MPa Integrated or cha

A double-curved boom rock drilling jumbo is designed to achieve higher drilling efficiency—often described as “double efficiency”—mainly through its expanded coverage, flexibility,

A wet shotcrete machine is widely used for slope stabilization and tunnel wall support because it offers high spraying quality, low rebound, and strong adhesion.

Converting a concrete boom pump truck into a wet shotcrete (wet spraying) machine is a practical solution widely used in tunnel and slope support construction, especially when a de

Wet shotcrete machine with one year warranty

A larger drilling hole diameter will significantly increase the drilling time due to the exponential increase in rock volume, higher power requirements, and greater challenges in c

Double-boom drilling rig → Best for medium tunnels, balance of cost and efficiency. Three-arm drilling rig → Best for large tunnels, faster and more versatile but more expensive

For water conservancy projects (like dams, irrigation tunnels, spillways, and diversion tunnels), the choice of rock drilling machine depends on the project scope, rock conditions,

Engineering chassis wet shotcrete machines are indeed more suitable for tunnel construction projects

A 30m³/h wet shotcrete machine typically requires a high-capacity air compressor to ensure smooth operation. The size of the air compressor depends on the air consumption of the sh

A truck-mounted concrete pump is extremely useful for tunnel support

Wearing a white T-shirt while operating a wet spray machine may not be the best choice.
