Proof Load Testing
Proof load testing of equipment is performed to establish fitness for use. Proof load testing is generally performed prior to initial use, periodically to confirm on-going fitness for use, and also following repairs to critical load carrying components.
In addition to cranes, equipment and machines which are typically proof load tested include lift beams, spreader beams, custom lift frames, slings, custom sling configurations, hoisting frames, derricks, pad-eyes, winch foundations, and other load bearing structures. Hydro-Wates® can provide certification of proof load test results to nationally and internationally recognized standards specified by API, OSHA, ASME, NSTE, IMO and others.
Generally proof load testing is performed at loads in the range of 10% to 25% over the normal working load limit (WLL) of the device being tested. However, in some cases the test load is greater and should always be in accordance with the manufacturer’s recommended practice.
Requirements From OSHA
Load testing is required on all overhead cranes. An initial inspection on new equipment is mandatory followed by periodic maintenance inspections according to OSHA. A "drop test" is required as part of the certification because it can reveal functional errors and lower the risk of a serious accident involving overhead cranes and hoists.
In addition, use of our equipment allows customers to meet the regulatory load testing requirements of OSHA, IMO and SOLAS.
Cranes being used in any industry can be load tested using water bags. Hydro-Wates offers proof-load testing services to companies across the United States and the world.View Crane Testing Options
