Busan Korea, a Liebherr Luffing tower crane suffered a collapse of the boom for reasons that are unclear in the article. the article notes, winds, striking other objects and other potential causes, but doesn't pin point a cause.

The crane was located about 400 feet up on the building that they were working on. Fortunately the boom landed on the building and didn't injure anyone. Also conveniently there was a second Luffing Tower crane at or on the same level that was able to service the repairs. The article in translation makes it appear that the boom was replaced and the crane was put back into service.

If the brake failed or the boom rope failed it's possible that no other damage occurred to the crane and with a new boom it would be safe to go back to work with some simple repairs.
