Some of those violations the company is still contesting.

OSHA is heading up what’s referred to as the forensic investigation regarding the crane accident.

Investigators are trying to figure out why the crane snapped and toppled over on the Elan City Lights Apartments.

The crane operator, Bigge Crane and Rigging Co., based out of California, flew a team out to Dallas Sunday night.

The model of the crane that fell is the Peiner SK 415. According to its specifications, the crane is designed for winds of 95 miles per hour.

Bigge Crane and Rigging Co. said it currently has 74 cranes in operation across the country.
