SAF-Holland's SmartSto Cuts Uncoupling Injuries and Connection Damage

Key Details SAF-Holland has introduced SmartSto, a new safety system that redesigns how drivers uncouple tractor-trailers. The system combines a fifth-wheel air release with dedicated storage for air gladhands and electrical cables, preventing accidental damage and injuries during routine disconnections. Why It Matters Traditional uncoupling requires drivers to reach under trailers to manually release the fifth wheel, creating injury risks and slowing operations. SmartSto moves the air-release control outside the cab next to the fifth wheel, eliminating dangerous reaching and making the process faster and safer. How It Works Drivers disconnect air and electrical lines from the trailer and stow them on the SmartSto module mounted on the tractor. The system verifies all connections are properly secured before allowing the fifth wheel to release. It also ensures the parking brake is set and prevents drivers from moving forward while lines are still connected. Installation and Timeline The system requires connections to only three air lines with no additional electrical hookup, allowing integration with existing fifth-wheel systems. SmartSto is expected to be available in the fourth quarter of 2026. Industry Impact Mike Ginocchio, SAF-Holland's VP of product management, emphasized the system addresses "a common and costly challenge" that happens thousands of times daily across the trucking industry. The innovation aims to protect both drivers and equipment while reducing expensive roadside repairs and downtime.
