Adroit 450G – 4×4 Shotcrete Machine With Generator

The Adroit 450G is a robust and versatile 4×4 shotcrete machine integrated with a dedicated generator, designed for demanding underground applications where independent power supply is essential. This model is ideal for remote or off-grid tunneling and mining operations that require a self-contained, high-performance spraying system.

Built for durability, the 4×4 chassis ensures superior mobility across rugged terrain, allowing smooth maneuvering in tunnel headings, inclined ramps, and uneven shafts. The integrated generator ensures that the shotcrete system can operate continuously even in locations without external power, eliminating downtime tied to infrastructure constraints.

The shotcrete pump and spray system deliver consistent, high-pressure flow, supporting both wet-mix and dry-mix applications (depending on configuration). Its hydraulic and pneumatic control systems provide precise dosing and steady material delivery, minimizing rebound and maximizing surface coverage. The machine is engineered for ease of maintenance, with accessible service panels, modular components, and robust wear parts.

Safety is a critical aspect: the Adroit 450G includes redundant safety systems, automatic shutdowns, and integrated instrumentation to monitor pressure, flow rates, motor performance, and electrical loads. Its cabin or operator platform is ergonomically laid out, offering clear visibility, control interfaces, and protection from dust and rock fragments.

With the Adroit 450G, contractors can confidently tackle challenging shotcreting tasks in new tunnels, underground infrastructure, or rehabilitation projects, while maintaining autonomy and reliability in even the most remote underground environments.
