From the Daily News:
The city Buildings Department on Sunday yanked the license of the operator of a 25-story monster crane that collapsed in Manhattan's Financial District.
Crane operator Christopher Cosban "failed to leave the crane in the safest position possible at the end of the work day," contributing to its Saturday night collapse, Buildings Department spokesman Tony Sclafani said.
Cosban failed to lower the hydraulically operated boom of the mobile crane as low as he should have, creating a serious hazard, sources familiar with the probe said.
Investigators hauled the 360,000-pound crane onto a truck and removed it for investigation.
During the day Saturday, the 250-foot crane was hoisting air conditioning equipment to the top of the building, but it was not in operation when it crashed.
Cosban's negligence contributed to the mishap but may not have been the only cause, Sclafani said. Buildings Department investigators also were probing possible mechanical failure.
The crash also is under investigation by the federal Occupational Safety and Health Administration.
