A crawler dozer working parallel to a 20-foot-deep trench rolled over into the trench, injuring the operator, according to local news reports.
Fellow workers at the site near Orlando, Florida, were able to free the operator from the machine before emergency personnel arrived. He was brought to a hospital for treatment.
Photos of the site show the side of the trench partially collapsed above where the dozer came to rest, but there is no word on whether it was a result of the rollover or the cause.
