を切り替え可能に構成された荷役用バランサ。 The base end of the arm, which can hold cargo at its free end, is supported on the frame so that it can move up and down and rotate, and is fitted into a screw nut that is driven forward and backward by a torque motor. In a cargo handling balancer equipped with an arm drive unit that drives the arm up and down with a shaft, the arm has a joint part in the middle part whose lateral length is set to be variable, and the arm drive unit is configured to move the arm up and down. A cargo handling balancer configured to be able to switch the torque transmitted from the torque motor to the screw nut depending on the set length of the screw nut.
