What is indicated if the fittings on boom sections are bent?

If the fittings on boom sections are bent, this directly impacts how the boom sections interconnect. Bent fittings can prevent the boom sections from aligning correctly, making it challenging or even impossible to assemble the crane as intended. This misalignment can lead to operational problems and safety concerns when the crane is in use, signalling that proper assembly is compromised.

While other answers also point to issues that might arise from bent fittings, such as the unserviceability of the crane or the need for inspection, the primary and most immediate consequence is the improper fitting of the boom sections. Properly understood, this answer highlights the mechanical aspect of crane assembly and the importance of maintaining the integrity of components to ensure safe operation.
