ABSTRACT:
A boom latch system for a boom movable between use and stowage positions. The boom latch includes a latch member that is operatively connected to the power supply which moves the boom, so that the boom is automatically unlatched when moved from its storage position. The boom latch includes a latch body which pivots to align with the boom latch receiving element, thereby aligning the latch members even under varying load conditions. The latch body also provides a length adjustment so that the latch system can be used with various sizes of booms and hydraulic cylinders.
