PROBLEM TO BE SOLVED: To provide a lift controller that does not generate large error in a lifting body stopping position due to presence or absence of load in the lifting body or difference in the lifting direction, can certainly stop the lifting body at a certain position, and has high lifting speed and high working efficiency. SOLUTION: When a position detecting means 4 gets into a detection state while the lifting body 2 is lifting, a control means 3 performs control to output a reverse braking signal to a motor 1 to stop the lifting body 2 in a short time. The lift controller has a load detecting means 5 for determining the presence or absence of the load in the lifting body 2. When the lifting body is lifted up in a presence state of the load, the reverse braking to the motor 1 is not performed even when the position detecting means 4 gets into the detection state.
