Examples of Non-Compliant Stage Rigging

Stage Rigging compliance and safety guidelines are always changing and aren't always followed. Below are some common compliance issues we see when performing stage rigging inspections, along with the corresponding reference to ANSI standards. The following standards are taken from ANSI E1.4-2-2021 STATICALLY SUSPENDED RIGGING SYSTEMS.

4.1.1 All statically suspended rigging system components shall contain rated, traceable hardware throughout the load path of the system.

4.2.2.1.2 All beam clamps with jaws attaching to both sides of a flange shall be used whenever possible.

Improper orientation and non-compliant use of beam clamp.

4.2.3.2 Open hooks and bent eye bolts shall not be used.

4.2.5.1 All shackles shall be forged carbon or alloy steel permanently marked wih the manufacturer's identification, size and load rating.

4.2.6.1 All quick links shall be permanently marked with the manufacturer's identification, size, and load rating.

4.2.7 S-Hooks S-hooks shall not be used in rigging systems covered by this standard.

S-hook making improper connection to building steel in an unsecure manner.

4.3.2.4 Weldless chain shall not be used.

Non-compliant "swingset" chain used.

4.3.2.5 Loading along the minor axis shall not be permitted (e.g. chain run over a hard edge).

4.4.1.2 The number of splices in a finished batten length shall be minimized as much as possible. Batten splices shall be constructed in a manner that retains at least the same strength as the unspliced batten material. The use of threaded pipe fittings shall not be permitted as a splicing method.

Non-compliant pipe splice using gaffer's tape.

4.4.1.4 The battens shall be capable of supporting at minimum 45 kg/m (30 lbs/ft) of uniformly distributed load (UDL). Battens shall be capable of sustaining a point load of 45kg (100 lbs) at mid-span between any two suspension points with a maximum span deflection of 1/180 of the span.

Non-compliant use of corroded or rusty chain.

4.4.2.3 Maximum deflection for a uniformly distributed load or a concentrated point load shall not exceed 1/180 of the span distance between adjacent suspension points.

4.4.7.4.1 Open hooks shall not be used in suspension of projection screens.

Usage of rusty chain and open hook resulting in unsecure connection.

The safety of your stage, performers and staff is our priority. If you have any "bad rigging" in your facility, or just want reassurance that your rigging system is compliant and operating safely, schedule an inspection today.
