If the boom length is between values listed on the load chart, which capacity should the operator use?

When the boom length falls between the values specified on the load chart, the safest approach is to use the smallest load indicated at either the next longer or shorter boom length. This method ensures that the operator remains within a safe operating range, as it compensates for the uncertainty introduced by the boom length measurement.

Using the smallest load at these adjusted lengths minimizes the risk of exceeding the crane's capacity, which is crucial for maintaining safety during lifting operations. It's important to remember that cranes are engineered with specific load limits based on various configurations, and staying below those limits is vital for preventing accidents.

Opting for the smallest load provides a conservative measure, ensuring that safety is prioritized, especially when exact dimensions fall outside specified capacities. This is particularly relevant in construction and lifting operations, where precision and adherence to load charts can prevent accidents and injuries.
