Adopted Rules: Closed to Comments

Effective Date:

Statement of Basis and Purpose of Rule 

The Department of Buildings (DOB) is adopting this rule to establish regulations for rigging equipment and rigging operations.  Rigging consists of the system of ropes, slings, hooks, and other hardware used to secure loads while they are being lifted or lowered by a crane or other hoisting machine.

The rule adopts national model standards published by the American Society of Mechanical Engineers (ASME) for rigging hardware, hooks, below-the-hook lifting devices, and slings.  Additional New York City specific provisions are also adopted.  Provisions for inspections, record keeping, and equipment identification are added to create a framework to verify compliance with the ASME standards.  Restrictions on repairs, alterations, and modifications are added to ensure these activities are performed in accordance with manufacturer requirements.  Other specific precautions for rigging operations and certain types of rigging equipment are adopted to prohibit practices that have led to past rigging failures in New York City.

Adoption of ASME rigging standards, with New York City modifications, was recommended by the Crane Safety Technical Working Group (“TWG”), appointed by Mayor Bill de Blasio and Buildings Commissioner Rick Chandler following the February 2016 crane collapse in Tribeca (TWG recommendation #8).

The Department of Buildings’ authority for these rules is found in sections 643 and 1043 of the New York City Charter and sections 3316.9 and 3319.9 of the New York City Building Code.
