The Optimum Length for Pulpwood1

Considerations affecting the efficiency of logging

J. W. L. ZEHETMAYR

Chief Work Study Officer, Forestry Commission

The effect of varying length of pulpwood is discussed in relation to place of conversion, loading, length of lorry, stacking space at roadside, method of skidding, and the preparation of loads after crosscutting at stump.

The conclusion is reached that for Scottish upland conditions pulpwood should be prepared in 10- to 12-feet lengths in two stages, the feller preparing loads for skidding and the horse or tractor roughly piling the unbarked pulpwood at roadside for mechanical loading on to long-distance transport. For the Fort William mill a standard length of 10 feet, with tolerance down to 8 feet, will be adopted.

Mechanization is not envisaged for some years beyond chain saw, tractor-mounted double-drum winch, and lorry- or tractor-mounted crane with hydraulic grab, while the horse will play its part in skidding for at least the next five years. Logging teams of four to eight men will be required and are being trained.
