Concrete spraying machine ALIVA 237

sprayelectricpneumatic

Overview
The Aliva 237 is a compact dry concrete spraying machine designed for conveying and applying dry shotcrete mixes. It features automatic lubrication of sealing gaskets and an integrated frequency converter for stepless rotor speed control. With conveying capacities from 0.2 to 4 m³/h (configurations also cited at 0.4–4.0 m³/h), the Aliva 237 adapts to a wide range of on-site applications in construction, repair and tunnelling.

Key specification

• Compact dry concrete spraying machine for conveying and spraying dry mixes
• Output range: 0.2–4 m³/h (alternative configuration 0.4–4.0 m³/h)
• Automatic sealing-gasket lubrication
• Integrated frequency converter for infinitely variable rotor speed

Features

• Automatic lubrication system for sealing gaskets
• Stepless speed adjustment via integrated frequency converter
• Emergency stop that also cuts off the air supply
• Available with electric or pneumatic drives
• Optional remote control
• Multiple rotor sizes for different output and material characteristics

Benefits

• High flexibility: compact dimensions allow quick relocation on site
• Continuous availability for dry mixes (oven-dry materials)
• Easy handling, cleaning and low maintenance requirements
• Operable with limited electrical expertise due to solid mechanical design
• Long conveying distances: up to 300 m horizontally and up to 100 m vertically (with pipes)
• Suitable for concrete repairs, pool construction, slope stabilization, tunnelling, mining and general construction
• Wide output range covered by a single machine
• Effective in confined or interruption-prone job sites
