Dear Mr. Pickett:
This in response to your letter of December 7, 1988, concerning the "Rated Load Test" for cranes as specified at 29 CFR 1910.179(k)(2).
Overhead and gantry cranes should not be rated in excess of 80 percent of the test load. Therefore, in order to rate a crane to 100 percent of the design intended loading, the test load must be 125 percent of the rated load. The only exception to this requirement would be when a crane manufacturer specifies a different test loading criteria. In that case, the crane manufacturer's procedures shall be adhered to.
If we may be of further assistance, please contact us.

Attn: Mr. Thomas S. Shepich:
Paragraph K2, part 1910.179, Title 29, specifies the upper limit of a Rated Load Test shall not exceed 125% of the rated load unless otherwise recommended by the manufacturer. Please specify wheat minimum load below 125% of the rated load is permissible in the rated load test, since none is specified in K2, 1910.179, Title 29.
Reference K2, 1910.179, Title 29.
