A moveable boom hinge apparatus is provided. The moveable boom hinge apparatus provides a mechanism offsetting the tip portion of a boom hinge from the base portion of a boom hinge when the tip and base portions are folded parallel to each other and securely position the tip portion of the boom when extended. Additionally, this moveable boom hinge apparatus provides a uniquely u-shaped link element and complementary u-shaped catch element that couple together in a way that sufficiently locks the tip portion into place with respect to the base portion and keeps structural loads of a boom hinge aligned with structural members of a boom hinge during its boom hinge's transition from the operational position to the non-operational position. This alignment significantly reduces bending moments that weaken structural materials over time. Therefore, this moveable boom hinge apparatus can be made with lighter, less-costly materials as opposed to the heavy, more costly materials that are currently used for boom hinge devices.
