LOAD TESTING of CRANES & HOISTS
Load testing is regulated by OSHA, who set the standards specifying requirements for load testing. ANSI standards in the OSHA standard 29 CFR 1910.179, for Overhead and Gantry Cranes states that Load tests SHALL be performed in the following two cases:
- New Overhead crane systems SHALL be load tested prior to being placed into service.
- New and existing equipment. All new overhead and gantry cranes constructed and installed on or after August 31, 1971, shall meet the design specifications of the American National Standard Safety Code for Overhead and Gantry Cranes, ANSI B30.2.0-1967, which is incorporated by reference as specified in Sec. 1910.6.
- Existing crane system SHALL be load tested after modification or re-rating.
- Modifications. Cranes may be modified and re-rated provided such modifications and the supporting structure are checked thoroughly for the new rated load by a qualified engineer or the equipment manufacturer. The crane shall be tested in accordance with code. New rated load shall be displayed in accordance with code as well.
- Test loads shall not be more than 125 percent of the rated load unless otherwise recommended by the manufacturer.
- Once a rated load test is performed, paragraph 1910.179(k)(2) requires that “the test reports shall be placed on file where readily available for review.
