A jib is often used to extend the height and reach of the main (primary) boom on a mobile hydraulic crane (see Figure). The jib can be in one of three States: 1. Stowed on the side of the main boom when not in use (Figure 1) 2. Mounted to the main boom head when lifting (Figure 2) 3. Moving from State 1 to State 2 and vice versa. Current mechanisms that are used during the dynamic State 3 often require significant readjustment and manual intervention to achieve State 1 or 2. Project Deliverables: • Multiple initial concepts • During the transition between each State, alignment of the jib between supports must be seamless and consistent. • It must not be possible during any State for the jib to become fully or partially unsupported • It is preferable that the operator can perform State 3 while working from the ground. • Pros and cons for the features of each design • 3D assembly model for selected design • Simulation and stress calculation data • Presentation to communicate findings
