Houston crane collapse investigation begins

An investigation has been launched into the cause of the mobile crane accident in Houston, Texas, US, which left four workers dead and seven injured.

The heavy lift lattice boom crane, operated by Deep South Crane and Rigging, collapsed at the LyondellBasell oil refinery on Friday, 18 July.

"We wish we had all the answers on what happened and why, but we do not, and speculation on cause would not resolve anything. But we are actively working to find those answers. We are fully engaged and cooperating with the Occupational, Safety and Health Administration (OSHA) in their investigation of the accident. Our common goal is to identify the root cause, correct any issue that may be found, and ensure that this type of tragic accident does not occur again," Said Deep South Crane and Rigging.

All four workers killed were employees of the crane rental company. "This is a terrible loss to the Deep South Crane and Rigging family. We are deeply saddened and sorrowful that this occurred."
