ABSTRACT A method of controlling a pair of hoist motors comprises delaying one about to raise a load whilst allowing the other to lower its load until a steady speed is reached, and then raising the load with the first motor. The regenerative current from the motor lowering its load at steady speed is offset against the drive current required for the motor raising its load.
