The AL-237 is a compact concrete spraying machine for dry-shotcrete as well as for small wet-shotcrete application of mortars. The low filling height of the hopper allows easy handling of pre-bagged materials with little effort. The integrated FU (frequency changer) enables a infinitely variable speed of the rotor and with it the conveying capacity for each specific job.
The AL-257 is the universal machine for the application of dry- and wet shotcrete in the thin-stream method. The new and very compact design of the machine impresses through its dimensions, weight and performance. With just 750 kg and dimensions as little as a small dry shotcrete machine, the Aliva-257 fits on every job site and is easy to install and operate.
