To provide a dew condensation prevention system of an elevator hoist capable of accurately determining the necessity of a dew condensation prevention operation of an elevator hoist and capable of preventing the occurrence of a dew condensation in the hoist.SOLUTION: A dew condensation prevention system of an elevator hoist acquires the temperature and the relative humidity in a hoistway 1. The system comprises a dew point temperature calculation part 20 to calculate the dew point temperature T1 in the hoistway 1 from the acquired temperature and the relative humidity in the hoistway 1, a hoist temperature acquisition part 22 to acquire the temperature T2 of the hoist 6, a determination part 23 to determine the necessity of the dew condensation prevention operation to increase the temperature T2 of the hoist 6 when the temperature T2 of the hoist 6 calculated by the hoist temperature calculation part 22 is greater than the dew point temperature T1 calculated by the dew point temperature calculation part 20 and is less than the temperature with a predetermined threshold temperature T3 added to the dew point temperature T1, and a hoist control part 27 to perform the dew condensation prevention operation when the determination part 23 determines that the dew condensation prevention operation is required.SELECTED DRAWING: Figure 3
