Helicopter Logging of Baldcypress in Southern Swamps

$21.50 plus tax (Refund Policy)

A Boeing Vertol-107 II helicopter with support men and equipment, yarding large baldcypress (Taxodium distichum (L.) Rich.) from a southern swamp, hourly produced 2,773 ft³ of wood at a cost of $2,087. The average payload was 120 ft³ or 7,747 lb, 70% of the machine payload capacity, with an average cycle time of 2.57 min. The cycle elemental times were poorly correlated with yarding distance, payload weight, stems flown, and density altitude. Positioning, descent, hooking, and ascending with the logs accounted for most of the variation and length of the average cycle time. A predictive equation of per cycle cubic foot volume as a function of payload weight and the number of stems flown was developed. South J. Appl. For. 10:92-95, May 1986.
