ABSTRACT:
Log handling attachments frequently encounter inadvertent log loss during transportation, and damage to the logs and the log handling forks (36,38) due to excessive loading. A log handling attachment (14) is provided which has a pair of log carrying forks (36,38), a clamp (48), an ejector (88), a first power device (50) actuatable to pivotally move the clamp (48) between open and closed positions (51,53), a second power device (93) actuatable to move the ejector (88) between log accepting and log rejecting positions (94,96), and an apparatus (70) actuatable to move the clamp between the closed position (53) and a log grappling position (86) relative to the ejector (88) at which the logs are elevationally supported above the forks (36,38). Thus the problems of log loss, log damage and fork failure is alleviated. The log handling attachment (14) is particularly suited for use on a lift mast (12) of a lift truck (10).
