Following another recent crane accident, New York City issued interim regulations addressing crawler crane safety requirements. These now include obligations to monitor forecasts and wind speed measurements, cease operations when wind speed thresholds are exceeded, generally 30 mph, with exceptions. There are additional requirements for crawler cranes with special configurations including prohibitions of use and the required presence on site of a licensed professional engineer. End of day records are required to be created by the operator. Notifications are required to be provided to the building department when twelve specified events regarding the use of a crawler crane occurs. The requirements can be found here http://www1.nyc.gov/assets/buildings/pdf/commissioner_order_crane_safety_req.pdf
