Abstract
An improved boom (24) for a sliding boom delimber (10) is disclosed formed from a prestressed, conventional I beam (28). A first segment of a cable bundle (70) extends from the grapple head (36) and is secured adjacent the lower flange (32) of the I beam (28). The second segment of the cable bundle (70) is inside and carried by an energy chain (74) and includes first and second, inversely related, linear portions interconnected by a third, C-shaped portion. A sag plate (60) is coextensive with the first segment and located on the opposite side of the first segment than the lower flange (32) for preventing the first portion from sagging and engaging the first segment. Sides (50, 52) extend from the outer edges of the I beam flanges (30, 32) for partially enclosing the energy chain (74). Supports (42, 54, 62) are provided for reinforcing the I beam flanges (30, 32), the sag plate (60), and a side plate (40) extending between the other edges of the flanges (30, 32) on the opposite side of the I beam (28) from the energy chain (74).
