ABSTRACT:
In the operation of heavy equipment such as wheel loaders the amount of force subjected to the linkage arrangement that connects the work implement to the loader is normally quite large. In order to accommodate such loading, it has been common practice to increase the size of the various components within the linkage arrangements. The increase in size has greatly increased the weight of the linkage arrangement thus reducing the performance capabilities of the machine. The present invention utilizes a linkage arrangement (10) wherein the specific points of greatest loading have been grouped together son the various components of the linkage. In doing so, only these areas will require areas of significant increases in mass to accommodate the more severe loading. Also the particular positioning between the various components is specifically designed to simplify their construction. These combined factors substantially reduce the overall weight of the linkage arrangement.
