When is it necessary to perform a boom capacity test?

A boom capacity test is essential when the load is unknown because it ensures that the lifting equipment can safely handle the weight before any lift is attempted. When the load is not specified, there is a risk of exceeding the boom's rated capacity, which could lead to equipment failure or accidents. The test helps to determine how much weight the boom can safely lift under specific conditions, taking into account factors like angle, extension, and environmental conditions. Conducting this test ensures safety and compliance with operational standards, making it a critical practice in lifting operations.

Performing a boom capacity test before every lift would be impractical, especially when the load is well defined, and the equipment is operated within its known limits. Additionally, testing only for heavy loads assumes that lighter loads do not pose a risk, which is not necessarily the case if their weight is uncertain.
