The Entertainment Services and Technology Association's Technical Standards Program

The ESTA Technical Standards Program was created to serve the ESTA membership and the entertainment industry in technical standards related matters. The goal of the Program is to take a leading role regarding technology within the entertainment industry by creating recommended practices and standards, monitoring standards issues around the world on behalf of our members, and improving communications and safety within the industry. ESTA works closely with the technical standards efforts of other organizations within our industry, including USITT and VPLT, as well as representing the interests of ESTA members to ANSI, UL, and the NFPA.

The Technical Standards Program is accredited by the American National Standards Institute.

The Technical Standards Council (TSC) was established to oversee and coordinate the Technical Standards Program. Made up of individuals experienced in standards-making work from throughout our industry, the Council approves all projects undertaken and assigns them to the appropriate working group. The Technical Standards Council employs a Technical Standards Manager to coordinate the work of the Council and its working groups as well as maintain a “Standards Watch” on behalf of members. Working groups include: Control Protocols, Electrical Power, Floors, Fog and Smoke, Followspot Position, Photometrics, Rigging, Stage Lifts, and Event Safety.

ESTA encourages active participation in the Technical Standards Program. There are several ways to become involved. If you would like to become a member of an existing working group, as have over four hundred people, you must complete an application which is available from the ESTA office. Your application is subject to approval by the working group and you will be required to actively participate in the work of the group. This includes responding to letter ballots and attending meetings. Membership in ESTA is not a requirement. You can also become involved by requesting that the TSC develop a standard or a recommended practice in an area of concern to you.

The Rigging Working Group, which authored this Standard, consists of a cross section of entertainment industry professionals representing a diversity of interests. ESTA is committed to developing consensus-based standards and recommended practices in an open setting.

Annex Notes Scope – This document is a minimum American National Standard. European standards use different parameters for hoists in the entertainment industry.

E3.4.3 Proof testing of hoist load chain is performed as part of the manufacturing process of the chain. Proof testing of load chain is not used as a method testing the condition of the chain after it has been put into use.

Chain proof testing is conducting at the chain manufacturing level.

E3.8 There are a variety of means to limit the travel of a hoist, including but not limited to the use of electrical contact type limit switches, physical stops on the load chain, position feedback encoders, and slip clutches. It is up to the manufacturer of the hoist to design the method for their product.

E4.3.2 By the nature of performing a dynamic load test, a load holding test of the brake will be performed in the normal course of the test. During a dynamic load test the operator will lift a load, stop the hoist, and then reverse the hoist to bring the load down. As the dynamic load test will normally be at 125% of the hoist’s rated load, the brake will be tested at the same level.

E4.3.6 Dynamic load testing of hoists is typically done with the chain very close to the upper limit of its travel, with less than 10 feet of chain being in use during the test. A dynamic load test that tested an entire length of chain would require a testing facility with the means to perform the load test with the hoist at its lower travel, in a straight path. The purpose of a dynamic load test is to verify the condition and load bearing capability of the load bearing components. The condition of load chain is best determined through a physical inspection. If the manufacturer identifies the chain end fitting as a load bearing component, then the hoist is subject to the testing requirements of 4.3.4.
