for tunnelfor underground miningoutdoor

Overview
Adroit 420AH is a 4×4 off‑road articulated shotcrete machine designed to access points in tunnels and mines where larger equipment cannot operate. The unit features a simple, serviceable design that enables on‑site maintenance by operators. The articulated chassis provides four‑wheel drive and stable mobility in confined or uneven work areas.

Key features

• 22 m³/h shotcrete pumping capacity
• 7.2 m lateral reach; 8.4 m vertical reach
• 6 m³/min compressor capacity (platform‑mounted)
• Perkins 74.5 kW diesel engine
• Hydrostatic drive system with variable flow pump and hydromotor

Description
The hydrostatic drive delivers a combination of maximum speed and maximum torque through a variable flow pump and hydromotor, allowing selectable gear options (fast or slow) to match road and ground conditions. This configuration is suitable for sites requiring high travel performance and operations on difficult terrain.
