Sažetak
This paper presents the results of measuring wheel loads of skidder during timber extraction. Research results are based on uphill and downhill skidding on two skid trails with continuous slope of 15 % and 30 %. Measurement of wheel loads was performed by tensiometric method and remote transferring of measurement signal. Distribution of wheel loads during timber skidding is shown in dependence of slope, load volume and skidding direction. Nominal ground pressure based on tyre size was determined for each wheel. The ratio between soil cone index (measured by cone penetrometer) and nominal ground pressure was used for the evaluation of environmental acceptability of skidder work. Due to winter period during investigation, frozen soil on skid trails had a very high capability to bear wheel pressures of skidders.
