The truck-mounted crane (TMC) is a cable yarder that shows promise for logging thinnings on moderate to steep slopes. A commercial thinning using the TMC yarder on moderate slopes in an overstocked stand of 60-year-old cherry-maple poletimber and small sawtimber showed that a 3-man crew could harvest 51 tons (21.5 cords) of tree-length logs per 8-hour day when extracting stems averaging 10 in dbh. The cost to fell, yard, and deck stems of this size averaged $9.60 per ton ($22.73 per cord), including cost of road construction. Truck-mounted crane yarding results in minimum damage to the residual stand, thus ensuring increased value of future crop trees. The environmental impact is light, because fewer roads are required, and forest soils and stream courses are disturbed less than with conventional logging methods. North J. Appl. For. 2:87-90, Sept. 1985.
