  • Patent number: 4106646
    Abstract: A lift truck has a log handling carriage head carried by a vertically movable boom. The boom is pivoted to the truck frame below the operator's cab to provide a clear line of sight from the cab along the top of the boom to the carriage head in any position of the boom. The carriage head comprises a pair of independently operable, vertically disposed, transversely separated, articulated claws. The claws are pivoted to opposite side extensions of the outer end of the boom for improved visibility to the load. Each claw includes a generally upstanding main carriage member, a fork extending forwardly from a lower end of such member, and a tusk curving forwardly and downwardly from the upper end of such member. The fork and main carriage member of each claw pivot about a common transverse axis, and the vertical angle of each fork is adjustable independently of the other by pivoting its associated main carriage member independently of the other such member.
