Equipment TypeB-C Deck Cargo Ramp 

ALATAS Americas was contracted to complete a full accident investigation, engineering & repair of a cargo ramp


The cargo ramp was lowered during a mission, and one of the locking dogs did not fully unlock.  This caused the ramp to lower under slack cables until the locking dog was bent and the ramp came down.  During this time, it shock-loaded the ramp structure and bent the main side frame and the sheave plate.


ALATAS immediately dispatched a service engineer to conduct an accident investigation.  The investigation and condition evaluation allowed ALATAS to offer a complete turnkey engineered repair solution, including an onsite team for repair.  All repairs were presented and accepted by ABS and the Military Sealift Command.
