  • Patent number: 5383563

When the work machine is in operation dirt and other debris can fall onto the moveable components of the outrigger structure thus a guard mechanism must be provided. The subject outrigger structure includes a guard member which is pivotally mounted to the top of the outrigger structure and is spring biased toward a pivotal leg member to cover a portion of the moveable components to prevent accumulation of debris on the moveable components to reduce wear on the outrigger structure. This arrangement of components provides a guard member which moves with the leg member to always maintain the guard member in position to cover the moveable components.
