PROBLEM TO BE SOLVED: To provide a cargo handling assistance device with a link chain which is compact, smooth in feeding out, and excellent in operation feeling of assistance.SOLUTION: A cargo handling assistance device comprises: a link chain 8 in which annular vertical links 9 and horizontal links 10 are alternately connected; a bottomed cylindrical load sheave 13 around which the link chain is wound; a motor part 2 for rotating the load sheave 13; a torque detection part 5 for detecting torque applied to the load sheave 13; a rotation angle detection part 4 for detecting at least one rotation angle of the load sheave 13 and the motor part 2; and a control circuit part 17 for performing calculation from the torque and the rotation angle to control assistance of upward and downward movement of a cargo handling object. The load sheave 13 has a plurality of vertical link pockets 11 and horizontal link pockets 12 alternately on an outer peripheral surface thereof. A side wall surface 24 of the horizontal link pocket 12 provided corresponding to a semicircular arc part of the horizontal link 10 is constituted by an inclined surface expanding toward an outer peripheral direction of the load sheave.SELECTED DRAWING: Figure 4
