Aerial Lifts for Working in Tree Tops

Engineers at the Missoula Technology and Development Center have identified aerial lifts as the most versatile and safe vehicles for work in tree crowns. Recent improvements in hydraulic and mechanical systems have made these lifts more appropriate for seed orchard tasks. There are two categories of lifts. Verticalhorizontal lifts are either self-propelled or mounted on a trailer or truck; they can be used to reach high places but are limited in the amount of weight they can hold. Vertical lifts are self-propelled units with relatively large platforms. Their height reach is limited to 182.8 m (60 feet), but they can lift up to 12,700 kg (28,000 pounds). Lifts suited for most seed orchard tasks can be rented or purchased. Tree Planters' Notes 45(1):21-25;1994.
