Title : Determination of the skidding road deformation caused by multiple crossings of Mht 8002 HV caterpillar harvester
Key words : skidding road, vertical profile, laser rangefinder, deformation, caterpillar harvester
Summary :

The objective of the paper was to measure deformations of the skidding road which were caused by single, double and triple crossings of caterpillar harvester Mht 8002HV.The measurements were carried out on the skidding road with a transverse slope (4.5º) to the axis of the road, and longitudinal (2.6º) to the axis of the skidding road. The measurements were carried out with the use of a device for remote imaging of the land surface. The device operates by moving Leica Disto Plus laser rangefinder over the tested surface with the use of the coordinate system controlled by a computer (CNS control). Based on the results, it was reported that three crossing of a harvester caused slight deformations of the skidding road, and slight transverse declination of the skidding road caused loading of the caterpillar and resulted in its 70% loading with the total weight of the machine in the centre of the caterpillar. Despite irregular loading of caterpillars, theoretically average unit pressure on soil caused by more loaded caterpillar did not exceed 70 kPa. Whereas, average depth of the rut, which was measured, after three crossings of the harvester was 4,8 cm and for the less loaded caterpillar it was 3,6 cm. Three crossing of the machine uncovered the root systems of trees and considerable relocations of the ground fragments.
