Load Distribution Plans for Forwarders

Abstract

The load distribution diagrams known from commercial goods traffic were used to assess the loading capacity of a forwarder. In order to be able to integrate the centre of gravity of the timber load into the diagram, it was assumed that the cross section of the stanchion basket was fully loaded. Based on this assumption, a linear load model was developed. For the loading calculation to be combined with the calculation of axle carrying capacity in a diagram, the coordinates of the permissible axle loads shown needed to be transformed so that the timber assortment length, which is more clearly understandable for the user, is employed in the diagram. This adapted load distribution diagram allows possible load, capacity, possible assortments, and load overhang to be determined. In addition to the possible load, this method provides the user with other significant information, such as axle load distribution, load weight, and gross vehicle weight. This technique is employed in KWF tests and the development of forestry machines.
