Aliva-267 concrete sprayer

The Aliva-267 is a larger, multifunctional rotor machine for dry-mix and wet-mix shotcrete, intended for larger spraying tasks such as tunnelling and excavation pits. The machine has a modular design, so integrated components can be adapted to the individual application. With the powerful electric motor, the desired output is achieved by switching the rotor speed (Advanced version), and in the Top Plus version the output can be infinitely adjusted up to 21 m³/h. For mechanised spraying, the Aliva-267 is designed for use with the Aliva-302.1 spraying arm or the small Aliva-503.3 spraying system.

The machine is available in four versions: Standard with a single-speed electric motor, Advanced with a two-speed motor, Advanced Plus with a two-speed motor and a synchronised Aliva-403.6 dosing unit for accelerator, and Top Plus with infinitely variable adjustment and an integrated, synchronised dosing unit. The rotor sizes are 15.5 and 26.5 litres. Theoretical output at 50 Hz:

• Standard: 9.0 m³/h (15.5 l) and 16.0 m³/h (26.5 l)
• Two-speed versions: 6.0/9.0 and 10.0/16.0 m³/h
• Top Plus: 4.0–12.0 or 8.0–21.0 m³/h

At 60 Hz the values are higher (up to 10.8 and 19.2 m³/h).

The maximum aggregate size is 20 mm, with a recommended maximum of 8 mm. The recommended hose size is DN 65 (DN 60), and the maximum conveying distance is 300 m horizontally and 100 m vertically for dry-mix spraying and 40 m and 15 m for wet-mix spraying; the manufacturer recommends steel pipes for distances over 80 m. The machine with a 15.5 l rotor on wheels weighs 1 500 kg and measures 2 110 x 935 x 1 330 mm. The standard configuration includes rotor chamber ventilation, an automatic lubrication system, a vibrating hopper, a pneumatically assisted clamping device, aluminium rotors and robust cover plates. Rubber sealing plates for dry-mix spraying and Converto accessories are available as options.
