To provide a pantograph overall measuring device equipped with a pantograph pushing-up force estimating function with which it is possible to detect the value and abnormality of a pantograph pushing-up force using values that are measured when calculating a slider thickness by a pantograph slider wear measuring device that measures the wear condition of a pantograph slider and provides information for slider replacement.SOLUTION: The pantograph slider wear measuring device comprises: a pantograph slider wear measurement unit for calculating the thickness of a pantograph slider from a difference between a reference surface on a pantograph measured from the installed height of a measurer by an optical cutting method and the top face of slider of the pantograph and thereby measuring the wear of the pantograph slider; and a pantograph pushing-up force estimation unit for measuring a change of height of an aerial wiring which the pantograph comes in contact with using a measurer and estimating a pantograph pushing-up force on the basis of a relationship between a push-up change of the aerial wiring and a pantograph pushing-up force and a change of measured height of the aerial wiring.SELECTED DRAWING: Figure 1
