We were appointed to investigate a floating crane incident in which the crane boom collapsed onto a barge, resulting in significant denting to the boom’s mid-section. Our inspection focused on identifying the cause and evaluating the condition of all lifting components. During the investigation, we confirmed that the boom hoist wire was in good condition, having been recently replaced. However, we found that the luffing wire had completely disengaged from the drum, indicating that it had not been properly secured with clamps during the recent wire installation. This improper securing allowed the wire to slip free under load, leading to the boom collapse.
To ensure a comprehensive assessment, we recommended our client to send the hydraulic motor and gearbox to the manufacturer for further evaluation, to determine if any secondary failures contributed to the incident. This case highlights our capability in identifying mechanical, procedural, and operational contributing factors in crane-related incidents and providing clear recommendations for correct action.
