Abstract: The technology disclosed relates a lumber grabber for grasping timber. The lumber grabber can achieve grasping large packages of lumber of various work lengths. In one configuration, the lumber grabber includes moveable forks for grasping lumber movably supported by a frame, affixable to a crane. Forks positioned at ends of the frame and arranged to open and close relative to one other under power by a source of motive force; thereby enabling grasping and ungrasping of packages of lumber under programmed control of a programmable controller executing stored instructions.
