Normet launches medium capacity spray robot 9 June 2015

Normet introduces its latest concrete sprayer, the Spraymec 5070 VC, which will be available for factory delivery from the final quarter of this year (2015).

The latest addition to the company’s fleet of vehicles aimed at the underground construction industry, features a Tier 4 Final (Stage IV) engine. It was unveiled at the Euro Mining exhibition in Tampere, Finland, on 20-21 May.

The Spraymec 5070 VC is designed for medium capacity spraying works and can be seen as the “little brother” of the Spraymec 8100 VC since it uses the same high performance carrier but comes with lower capacity spraying capability.

Features include the new SB307 spraying boom to provide good reach in tunnel profiles of up to 7m. The boom is equipped with self-lubricating slide pieces and roller to minimise wear. All boom movements are pressure compensated and have proportional functions, allowing the operator to complete a smooth and homogeneous tunnel lining structure.

The Spraymec 5070 VC uses Normet’s low pulsation concrete spraying pump (NSP30) and has a theoretical concrete output 28 m³/h and an FAD 10m³/ min at 7 bar screw-type compressor for generation of an air supply capable of supporting medium capacity spraying works.

The same nozzle operator interface is available for the Spraymec 5070 as is standard on the Spraymec 8100. This facilitates the control of all spraying functions via remote control and following spraying process parameters via a multi-coloured display at the front of the machine.

Highly accurate accelerator dosing is available either by using the mono-type screw pump or the optional low-pulsation Normet LPP-D peristaltic pump.

The Norsmart control system can log all spraying process and carrier data including concrete and accelerator volume, dosing percentages, pumping speed, changes to process parameters, logging engine and compressor hours, hydraulic oil system pressures and temperature. The NorSmart system also enables full fault-finding diagnostics.

Recorded data can be delivered for supervisory checks via USB drive, or, alternatively, machine data can be sent out to an external server via WLAN and GPRS.

The Spraymec 5070 VC can be supplied with either a Tier 3 engine (Deutz) or a Tier 4 Final engine (Cummins). The Tier 4 Final technology uses Selective Catalytic Reduction and DEF/Ad-Blue (Diesel Exhaust Fuel) technology.
