This method for setting a hoist that is equipped with an encoder for detecting the rotation speed of a drive motor and that lifts and lowers an article by rotating a load sheave using a driving force of the drive motor so as to roll up and roll down a load chain, the method comprising: a drive step for driving the drive motor at a constant rotation speed while applying a tensile force to the load chain; a storage step for storing, in a storage means, positional information obtained from the encoder in the drive step and a motor torque command value for controlling the drive motor in association with said positional information; and a speed correction curve calculation step for calculating a speed correction curve for driving the drive motor on the basis of cyclical variations in the motor torque command value stored in the storage step.
