Designed for mechanically sorting and stacking lumber, ties, and cants, the Stac-Trac can do the work of two to five men on a green chain. This unit will lift and stack timbers difficult or impossible to do by hand, reducing labor costs and decreasing injuries associated with material handling. One operator easily controls travel along the track, the lumber grapple, extension and up and down motion of the boom, and the unit's swinging motion, all from a comfortable, adjustable operator's seat.
