What is the maximum allowable back lash for a jib?

The maximum allowable backlash for a jib being 5 degrees is important for ensuring safe operation and maintaining precision in the positioning of the load. Backlash refers to the degree of movement or lost motion between two connected components, such as the jib and the crane's main arm.

When backlash is excessive, it can lead to imprecise load positioning, which increases the risk of accidents and potential load swings. A limited backlash of 5 degrees helps maintain control over the load during operations, thereby enhancing safety.

In the context of mobile cranes, adhering to the specified backlash limits is crucial for the performance and stability of the crane system. A degree of 5 degrees reflects a balance between operational flexibility and the need for tight control, making it suitable for various lifting scenarios and conditions.
