Spraymec 8100 VC is an electro-hydraulic self-propelled mobile concrete sprayer which optimizes concrete spray- ing in tunnel projects with variable tunnel cross-sections. It provides efficient spraying from one set-up in tunnels of up to 10.3 m in height and 16 m in width. The maximum vertical spraying reach is 14 m. The compact design enables the mobile sprayer to perform spraying in tunnels with cross-sections from 15 – 140 m2.
The Spraymec 8100 VC is designed for high performance sprayed concrete applications and the use of alkali-free accelerators. It features the latest state-of-the-art control system of the spraying process, the NorSmart2. The NorSmart2 concrete sprayer control system provides efficient, productive and high-quality concrete spraying with functions like:
• Low-pulsation concrete spraying and pumping
• Accurate and reliable accelerator dosing (accelerator dosing integrated into concrete output)
• Accurate and fast spray boom and nozzle movements and positioning
• Real-time control and diagnostics of the spraying process including optional kit for accelerator, concrete and ambient
• temperature control
• Logging of all spraying process-related data and USB data transfer• Comprehensive vehicle fault diagnostics
The Normet concrete spraying pump NSP 40 has a theoretical maximum pumping capacity of 40 m3/h when the casting option is selected. The standard pumping capacity for spraying operations is 30 m3/h. The concrete pipe support arm at the forepart of the concrete pipeline makes cleaning of the concrete line easy and fast after each shift. The work can now be completely carried out by one operator as the strong mechanical arm makes the pres- ence of an assisstant unnecessary. The upper part of the concrete hopper can be turned away for easy service of the concrete cylinders.
Spraymec 8100 VC has an onboard compressor with a capacity of 12 m3/min for efficient and high quality sprayed concrete application. Four-wheel drive and four-wheel steering makes the Spraymec 8100 VC easy to manoeuvre in demanding driving conditions and limited tunnel spaces.
The innovative layout of the Spraymec 8100 VC features genuinely easy access to all service points on the machine. With the new layout 1 x 1000 litre accelerator tank, a 400 litre water tank and a large tool and storage box or alter- natively 2 x 1000 litre accelerator tanks together with other options can easily be placed on the vehicle.
