What does the standard say about load testing my overhead cranes?

Current specifications regarding the load tests of Overhead Crane Systems

ANSI B30.11 requires the following:

11-2.2.2 Rated Load Test: (a) Prior to initial use, all new, extensively repaired, and altered equipment shall be tested and inspected by, or under the direction of, an appointed or authorized person, and a written report should be furnished by such person, confirming the load rating of the system. The load rating should be no more than 80% of the maximum load sustained during the test.

OSHA 1910.179 Paragraph K2 states the following:

Rated load test: Test loads shall not be more than 125% of the rated load unless otherwise recommended by the manufacturer. The test reports shall be placed on file where readily available to appointed personnel.


Hoist: A machinery unit that is used for lifting and lowering a load.
Crane: A bridging structure that spans two or more runways and provides traversing motion.
Runway: The rails, beams, brackets and framework on which the crane operates.


In Hoosier Crane's opinion, it is the owner's responsibility to load test the overhead bridge crane system. The "system" consists of the hoist, crane, runways, columns and footings. Testing the "system" requires that the full system be in place.  Therefore, testing must occur after the completion of the crane installation. Although it is a hoist industry practice to load test every hoist prior to shipping, this practice does not preclude the requirement for the full load testing upon commissioning of the full hoist, crane and runway system.
