This is in response to your August 31 letter requesting a compliance determination from the Occupational Safety and Health Administration (OSHA) regarding the acceptability of load testing a crane to 110% of its capacity in order to meet contractual requirements. Proof load tests can be performed on various pieces of lifting and rigging equipment, and are designed to ensure that the piece of machinery being tested is able to lift the design load without failure or deformation (yeliding). Some relevant information can be found in general industry standard 29 CFR 1910.179, which addresses overhead and gantry cranes. (e) If a load test is performed, operations shall be performed … (2) In the case of uncertificated cranes which have been in use, at the time of initial certification and every 4 years thereafter. Learn how the experts at OSHA say you should test lifting equipment, from gantry cranes to lift tables to forklift battery handling devices. Overhead Crane Safety Training: Overhead Travelling Cranes, Gantry Cranes, overhead crane, Jib Cranes, and Monorail Hoists are used widely for material handling. Application. It is also interesting to note that current OSHA standards (1910.179) now allow load testing (when required) at 100 percent of capacity in lieu … 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. n. The safe operation of such cranes requires operators to have the knowledge and competence to avoid an accident. CAUTION: Not applicable to load-sensitive reactor type hoist controls. ... OSHA Requirements for Testing Industrial Lifting Equipment. This section applies to overhead and gantry cranes, including semigantry, cantilever gantry, wall cranes, storage bridge cranes, and others having the same fundamental characteristics. Modifications. Test loads must not be more than 125% of the manufacturer's rated load unless otherwise recommended by the manufacturer. OSHA requirements are set by statute, standards and regulations. test load for crane and for maximum test load at maximum radius of crane. As rated load testing is part of section 1910.179, employers are required to perform the test on new and altered cranes in order to be compliant with the requirement in 29 CFR 1910.179 (k) (1). (d) If a load test is conducted, the person conducting the load test shall prepare a written report of the load sustained during the test and the operations performed during the test. 1910.179 - Acceptable use of load-limiting clutches as upper and/or lower limit … Also, section 1910.179 contains other provisions that necessitate load testing to ensure compliance. Products + Overhead Crane ... the lifting crane equipment is tested with loads up to 125% to verify the lifting equipment meets OSHA standards. While OSHA standards do not spell out overhead crane training requirements, the American Society of Mechanical Engineers does get much more specific in the ASME B30.2 standard. load chain is properly reeved and that rope or load chain parts are not twisted about each other. Overhead and gantry cranes should not be rated in excess of 80 percent of the test load. The only exception to this requirement would be when a crane manufacturer specifies a different test loading criteria.
