The cargo handling link 13 is opened by the extension of the cargo handling cylinder 14.
is swung upward around the support shaft 12, and the long object handling device 20 is moved upward, the industrial vehicle 1 is driven forward, and the log 3 of the target diameter is moved.
The effecting body 24 is positioned above the end of 9. Next, the cargo handling cylinder 14 is contracted, the cargo handling link 13 is swung downward, and the effecting body 24 is driven into the end of the log 39. Then, the industrial vehicle 1 is driven backward to move the logs 39 while dragging them in the length direction, and carry them to a place where pieces of similar diameter are collected. During such dragging work, as the industrial vehicle 1 turns (steering), strain occurs between the effecting body 24 and the log 39, but this is because the shaft body 22 is vertically resisting the spring 36. It can be absorbed by rotating around the axis 23. As mentioned above, the log 39 is placed in the designated location.
After the cargo handling cylinder 14 is extended and the cargo handling link 13 is raised, the working body 24 can be extracted upward from the log 39, and the industrial vehicle 1 is driven to the loading/unloading location. Note that when the effecting body 24 is extracted, the shaft body 22 is rotated back to the neutral position by the elastic force of the spring 36, and is automatically returned to the optimum direction for driving the effecting body 24.
