Disclosed is a winch control apparatus for a crane, which comprises: a first compensation torque value calculation section (21) which calculates, when a hoisting manipulation being input, based on a difference speed between a detected rotational speed and a target speed according to a manipulation amount of the hoisting manipulation, a first compensation torque value for enabling an electric motor to generate a reverse-rotation-preventing torque which is a torque in a hoisting direction and corresponding to the difference speed; and a second compensation torque value calculation section (22) which calculates, when the hoisting manipulation being input, based on a detected load value, a second compensation torque value for enabling the electric motor to generate a load bearing torque which is a torque in the hoisting direction and necessary for bearing a load of the load value.
