What is an Anti Two Block Warning System?

Anti two block (ATB or A2B) warning systems are used to warn or prevent the crane operator from two-blocking the crane. 

Two-blocking is a dangerous condition where the hook block is raised until it contacts the boom tip. 

Without a proper crane A2B system, a two-block can cause expensive damage to the crane boom, personnel and surrounding property.


Why Choose WTAU brand anti two block warning system?

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 cranes hook block is raised to a height where it comes into contact with the boom tip. 

This precarious situation can cause the cranes 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.
