Crane Proof Testing

Crane proof load testing involves a crane lifting a known load in line with its rated load capacity to verify its strength and ability to safely lift that load. The proof load test is normally expressed as a percentage of the working load limit (WLL) or safe working load (SWL) that the crane is designed to withstand. Typically, a crane proof load test will be carried out following manufacture, repair, refurbishment, modification or an overload incident. Periodic testing may also be specified as part of the asset owner’s quality procedures.

Every load cell that LCM Systems manufactures is designed to operate to the highest accuracy and in the toughest of environments. We offer a variety of products suitable for crane proof testing applications and can supply the load cell only or a complete load monitoring system that incorporates instrumentation and/or a display. 

For this application, wireless systems are often preferred, as the requirement for long lengths of trailing cable is eliminated, making installation much faster and simpler. In addition to our cabled products, we also have a comprehensive range of wireless load links and load shackles, which when combined with Mantracourt’s renowned T24 wireless instrumentation products, provide a reliable, out of the box wireless solution.
