An information presentation system includes: an overload preventing device that derives a load factor which is an index of a load applied to a rope; a data logger that accumulates data on the load factor derived by the overload preventing device and data on a time length for which a load corresponding to the derived load factor has been applied to the rope, the data on the load factor and the data on the time length being associated with one another, and generates lifting rope statistical information and raising rope statistical information indicating a relationship between the load factor and the cumulative time for each rope; and a presenting unit that presents the lifting rope statistical information and the raising rope statistical information generated by the data logger.
