What is the main boom angle when installing a jib on a crane?

When installing a jib on a crane, the main boom angle is typically at 0 degrees. This means that the boom should be in a horizontal position to ensure stability and to effectively support the jib during the installation process. A 0-degree angle indicates that the boom is level with the ground, providing a solid and balanced platform for the jib assembly. This configuration minimizes the risk of instability that could arise from having the boom at an angle while attaching or securing the jib. Proper positioning is crucial for maintaining safety and efficiency in crane operations.
