HSC-2008 wet shotcrete system with spray arm equipments have multi-function and can be applied widely.

HSC-2008 shotcrete machine with spray arm is suitable for roadway tunnels, railway tunnels, smaller tunnel section, smaller shotcrete amount, hydro-power tunnels and underground metal mines, perfect in spraying efficiency and performance.

1. HSC-2008 adopts arm structure of small size straight arm. Both two models shotcrete system can be used in small tunnel section and rotate the arm to spraying position.
2. The joints and freedom of motion can meet the requirement of spraying concrete. It’s reliable, stable and convenient. There are flood lights on both two sides of arm for spraying.
3. HSC-2008 shotcrete system equipped with hinge type chassis and diesel engine. We also adopted hydraulic torque converter and gearbox transmission, four-wheel drive, hinge hydraulic rotation, four-wheel hydraulic service brake, transmission shaft mechanical parking brake.
4. Transversal arrangement cab which makes it’s easy to operate without turning around. There are forward and reverse gears, high speed and low speed gears.
5. There are hydraulic support arm at the both sides of spray arm base, which ensure the stability of arm stretch.
6. There is diesel engine which ensures the arms can be folded and cleaned when electric power is off.
7. Reliable hydraulic pump and hydraulic valves adopted to ensure the whole pump reliable.
