Normet introduced its new concrete sprayer Spraymec 5070 VC with Tier 4 Final (Stage IV) engine in the Euro Mining exhibition in Tampere, Finland last month. It is designed for medium capacity spraying works and it can be seen as a “little brother” of Spraymec 8100 VC as it uses the same high performance carrier but comes with somewhat lower capacity spraying features as the “big brother”.

New features include the new spraying boom SB307 providing good reach in tunnel profiles up to 7 m. The boom is equipped with self-lubricating slide pieces and roller to minimize wear and tear. All the boom movements are pressure compensated and have proportional functions allowing operator to create smooth and homogeneous tunnel lining structure.

The Spraymec 5070 VC uses Normet’s low pulsation concrete spraying pump (NSP30) with a theoretical concrete output 28 m³/h and  FAD 10 m³/min/7 bar screw –type compressor which gives reliable and sufficient air supply for medium capacity spraying works.

The same intuitive nozzleman’s interface is available for the Spraymec 5070 as is standard for the Spraymec 8100. This includes operator being able to carry out all spraying functions from the radio remote control and follow spraying process parameters though a turntable and movable multi-coloured display placed on the front of the machine. Ease of service is arranged through open access to all service points.

Highly accurate accelerator dosing system either with mono-type screw pump or optional low-pulsation Normet LPP-D peristaltic pump is synchronized automatically with concrete output

Norsmart control system can log all spraying process and carrier data such as concrete and accelerator volume, dosing percentage, pumping speed, change of process parameters, engine and compressor hours, hydraulic oil system pressure and temperatures etc. The NorSmart system also provides full fault diagnostics.

The recorded data can be delivered to supervisory checks via USB drive or machine data can be sent out to an external server via WLAN and GPRS..

The available engine options for the Spraymec are Tier 3 (Deutz) and Tier 4 Final (Cummins).

The Tier 4 Final technology utilizes SCR (Selective Catalytic Reduction) and DEF/Ad-Blue (Diesel Exhaust Fuel) urea technology for exhaust after treatment.

The new Spraymec 5070 VC is available for factory deliveries in Q4 2015.
