Concrete spraying machine ALIVA 257

pneumatic

Overview
The Aliva 257 is a versatile industrial shotcrete (sprayed concrete) machine designed for dry and wet mixes in small to medium volumes. Its combination of durable rubber sealing plates and robust steel plates reduces wear and downtime while enabling low-dust, low-rebound application in confined or remote sites.

Key specification

• Application: shotcrete / sprayed concrete for dry and wet conveying
• Output capacity: 0.7–9.6 m3/h

Features

• Capable of long horizontal (up to 300 m) and high vertical (up to 100 m) conveying distances with pipes
• Reduced dust generation and rebound for cleaner application
• Light, compact design suited to confined areas and repair jobs
• Stepless adjustment of conveying capacity for precise control
• Durable rubber and steel sealing plates for low wear

Benefits

• High operational flexibility and rapid relocation on site
• Continuous availability with oven-dried mixes
• Easy handling, fast cleaning and low maintenance requirements
• Pneumatic drive option for use where electrical power is limited
• Wide output range from a single unit to match varying job demands
• Lower cement/fines consumption compared with pumpable concrete and reduced sensitivity to oversized particles
