PROBLEM TO BE SOLVED: To solve the problem of difficulty in performing lift operation in picking a grain bag placed directly on a floor surface by a lift fork because the tips of forks are hard to be inserted in between the floor surface and the bag side surface, but are likely to scratch or break a bag bottom part. SOLUTION: In this lift fork for a movable lifter, picking surfaces 2 of a pair of forks 1 on the right and the left is formed with gentle inclination A formed inwardly downward. As the fork 1 on the front side of a frame is lowered to approach the floor surface C, the movable lifter is advanced toward the fork 1 on the front, and it is pushed and guided in such a way that the grain bag B placed on the floor surface C is picked into a picking gap part D between the forks 1 on the right and the left. Since the picking surfaces 2 of the forks 1 on the right and the left are inserted along side gap parts between lower angular parts on both sides of the grain bag B and the floor surface C, a right and a left side parts of the grain bag B can be widely and deeply supported by the picking surfaces 2 having the gentle inclination A. The grain bag can thus be lifted and transferred in a stable state, without falling off. COPYRIGHT: (C)2005,JPO&NCIPI
