Abstract

In many applications, a loader performs a loading operation that includes, sequentially: digging and/or crowding a stock pile, racking back the bucket to maintain the load, travelling to a dump site or a transport vehicle while raising the bucket, and finally dumping the load from a raised position. For many devices, such as payload monitors and productivity indicators, it is important to have an indication of which function in the loading operation is being performed. A loading function identifier senses, stores, and averages the hydraulic pressure in a lift cylinder. The sensed and averaged data are compared to a series of predetermined constants to identify the function being performed. The algorithms used in this invention are applicable to a number of work vehicles having at least one work implement linkage and at least one hydraulic cylinder for modifying the linkage geometry.
