Spraymec 8100 VC is an electro-hydraulic self-propelled mobile concrete sprayer which optimizes concrete spraying 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 for the spraying process, the NorSmart. The NorSmart 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 (control system integrated into concrete output) Accurate sprayboom and nozzle movements and positioning Real-time control and fault diagnostics of the spraying process, including a kit for accelerator, concrete and ambient temperature measurement Logging of all spraying process-related data and USB data transfer Comprehensive vehicle fault diagnostics The Normet concrete spraying pump 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 presence of a helper 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 a revolutionary service technician's passage through the whole sprayer. This allows genuinely full and easy access to all service points on the sprayer. With the new layout, 2 x 1000 litre accelerator containers or one 1000 litre container, a 400 litre water tank and a large tool and storage box, together with other options, can easily be placed on the sprayer.
