Wheel loaders used in quarries usually repeat scooping and loading actions as face operations. So it is relatively easy to automate the operation and it also contributes reduction of cost and workers. The authors proposed the efficient trajectories for scooping piles with homogeneous rocks. On the other hand, there are often massive rocks in piles at the faces of quarries. Such a massive rock is usually picked up by inserting the loader bucket into the pile just below the rock. In our previous study, it was found that the consumption energy for picking up a massive rock becomes less by choosing the pushing operation. However, it is not clear why the reaction forces become constant and how the value is determined. In this research, the relationship between the physical phenomenon and the reaction forces are analyzed and the reaction force model is developed.
