When is it permitted to bypass the Load Moment Indicator (LMI)?

Bypassing the Load Moment Indicator (LMI) is permitted during assembly and disassembly of the crane because, at these stages, the crane is generally not in its operational mode and may not need to maintain the same safety parameters that the LMI provides during active lifting operations. The LMI is designed to prevent overload by monitoring the load and crane configuration but during assembly and disassembly, the crane is typically tested or set up in configurations where load loads that would otherwise trigger the LMI may not be present.

In operational situations, bypassing the LMI poses risks as the system is crucial for ensuring that the crane does not operate under unsafe conditions, which could lead to accidents or equipment failure. Consequently, it is strictly advised to rely on the LMI when lifting loads or during operations that could cause an overload condition.
