WFA Engineering pneumatic cattle stunning box, also widely named cattle knocking box, is core front-end restraining and stunning equipment for standardized beef slaughter lines, widely adopted in commercial abattoirs, large cattle slaughterhouses and halal ritual meat processing plants globally. The whole frame adopts hot-dip galvanized steel, and animal contact parts are made of food-grade 304 stainless steel with seamless welding, no sanitation dead corners, easy high-pressure flushing and disinfection, fully compliant with CE, HACCP and international animal welfare standards. Equipped with pneumatic locking head fixture and automatic tipping mechanism, this restrainer box firmly immobilizes live cattle for captive bolt stunning, electric stunning or halal ritual slaughter, then gently flips the bovine flat to complete shackling, bleeding and overhead hanging procedures. Built-in emergency stop, anti-collision buffer and adjustable clamping force greatly reduce cattle stress and operator safety hazards. Stable pneumatic driving system supports 60–100 cattle per hour throughput, drastically cutting manual labor. Customizable size, power and control modes enable seamless docking with existing cattle conveying rails, an essential automated stunning solution for modern livestock processing factories worldwide.
