In the summer of 1987 we studied the operations of the Moxy cable crane in South Trondelag county, Selbu district, Norway. Production rates far Moxy cable crane were established far short distance skidding of whole spruce trees. Clearcut area had 1. 03 ha with the average standing volume of 205 m$^3$/ha. We studied performance in 5 different settings. The stress was given on evaluation of the slope, distances and load size influence on daily production rates. Exponential type of regression analysis showed among some other tested the best significance. The results show that the Moxy cable crane is a very efficient machine for skidding whole trees downhill at short distances and in difficult terrain.
