A mobile crane with booms over 200 feet requires a load indicating device when the capacity is greater than what weight?

A mobile crane with booms extending over 200 feet is subject to specific regulations due to the complexities and risks associated with lifting heavy loads at significant heights. When the crane's capacity exceeds 50 tons, a load indicating device becomes necessary for safety and operational efficiency.

This requirement is in place because as the weight carried by the crane increases, so does the potential for catastrophic failure or accidents if loads are inaccurately measured. A load indicating device helps prevent overloading, which is crucial for maintaining stability and control, particularly for cranes with long booms that may have reduced lifting capacity due to the added distance from the point of operation to where the load is applied.

In terms of safety regulations, the implementation of load indicating devices for cranes handling loads over this threshold aligns with industry standards and best practices, ensuring that operators can continuously monitor the load weight and prevent accidents related to overloading.
