Crane Warning Systems


An Anti Two Block Warning System is an integral safety device for your crane. The system helps prevent the crane operator from having a two-block accident.  This is where the crane’s hook block is raised to a height where it comes into contact with the boom tip. This precarious situation can cause the crane’s boom to bend and to break the hoist line causing some serious damage to the property and lives in the vicinity. We urge all crane operators to invest in a crane two-block system. Our Anti Two Block Warning Systems come with audio and visual alarms along with outputs for lock out controls.  We have ATB systems to fit any type of crane.
