In the previous paper, dynamic behavior of a lifted load on a propelling crawler crane was studied. A suitable simulation model, which can take into account road shapes, was developed. In this study, numerical calculations were made for the dynamic load factor of a crawler crane with a lifted load during propelling. Consequently, the effects of road, working radius and propelling speed on the dynamic load factor have been clarified. A new ratio, "increase ratio of dynamic load factor, " which will be useful in the calculation of a rated load during propelling with a lifted load is proposed.
