Tunelmak Adroit 420H | 4×4 Shotcrete Machine
The Tunelmak Adroit 420H is a compact yet powerful 4×4 shotcrete machine tailored for smaller tunneling profiles or projects where maneuverability in constrained spaces is paramount. Despite its smaller footprint, it retains robust performance capabilities suitable for rigorous underground application.
The 420H is powered by a hydraulic drive system that ensures smooth, pulse-free material flow, enabling better nozzle control and reduced overspray. It is optimized for wet-mix shotcreting and is particularly useful for tunnel cross-sections where space is limited or where quick repositioning is required.
Because of its more compact design, maintenance and servicing are simplified — components are more accessible, and the modular layout ensures downtime is minimized. Operator ergonomics remain high — control stations are designed for clarity, safety, and ease-of-use even in tight operating conditions.
The 4×4 mobility ensures that the 420H can handle steep gradients, muck zones, and traverse across uneven underground trackways. It is a strong choice for smaller metro tunnels, utility tunnels, or service drifts where a balance between capacity and agility is needed.
