A fundamental step of process analysis and modelling for the scooping and loading function of a loader type excavating machine is carried out. This is a part of the essential work towards automation of such a machine. Emphasis is given here to Load-Haul-Dump mining machines, frequently used in underground mining operations. However, for many other applications, such as remote excavating and contaminated soil removing with a loader type excavator, the same theory applies and the same sort of experimental work becomes necessary. In this work the loading gear is first modelled as a mechanical manipulator, then the nature of the involved resisting forces, that also depend on the properties of the material to be loaded, and the fact that some knowledge about these stochastic forces is required, is pointed out. The paper, moreover, presents a discussion about the more appropriate trajectory of motion of the loader bucket.
