    • The facility determines the time to review, and plan re-submissions for any reason are billable.
  • Rigging plots must include all flown equipment, published weights per point, final trim heights by truss line, and a reflective ceiling plan.
  • A weight calculation will be conducted of all rigging points and confirm adherence to the Working Load limits of the Mountain America Expo Center’s structural documentation.
  • Any overweight points or unsafe scenarios will be addressed and will need to be changed, upon which the entire document must be resubmitted for approval.
  • Any on-site additions or deviations from the approved plot must be reviewed and approved before being implemented and flown out.
  • The rigging contractor must be able to demonstrate, upon request, all equipment and labor safety requirements as detailed in this document. Any unsafe or unapproved practices will not be permitted.


  • All rigging crews shall be led by an ETCP certified rigger. Evidence of current ETCP certification shall be provided to the facility at least 48 hours prior to load-in.
  • Lead rigger shall be responsible for supervising crew and enforcing policies within this document.

Rigging Point Attachment & Rigging Hardware

  • Rigging is only permitted on building structure that has a stamped working load limit from a PE.

  • Hanging from any other objects or fabric of the facility, such as plumbing, electrical fixtures, HVAC, or supporting infrastructure, is strictly prohibited.
  • All rigging point attachments must be created with ANSI-approved hardware.
  • All hardware (shackles, pear links, STAC chain, wire rope, slings, Gacflex, etc.) must have a stamped working load limit at a minimum of a 5:1 design factor, and must be product traceable.
  • Rigging Point construction standards:
    • All points/ hitches require the use of either burlap or other padding to protect both facility structure and a proper D/D ratio for supporting cable. (Not needed for Gacflex.)
    • Bridal points shall not exceed 120° between legs.
    • All rigging points must have a minimum of 24” of clearance from every fire sprinkler head.

  • All aluminum structures (truss) must adhere to PLASA E.1.2.5‐6
    • Proof of annual inspection must be presented prior to use.
    • Ground-supported systems must have known working load limits and ballast requirements in the vertical orientation.
    • All truss wraps where a motor is to be attached must have a wire rope safety cable with minimal slack. (Not needed for Gacflex.)
    • ALL items flown on the truss must have a safety cable.
    • All hardware used to suspend items must be rated hardware and used in an appropriate fashion.
