Abstract :
This paper deals with tipping over of hydraulic excavator´s crane work. If the excavator lifts too heavy weight, the excavator will be tipped up. This accounts for 38% of whole excavator accidents. In this paper, tipping-over load which is the maximum load the excavator can lift with displacement of excavator links, real load and tipping-over rate are computed with zero moment point theory. ZMP is verified with simulation and experiment.
