PROBLEM TO BE SOLVED: To provide a marking device for slip measurement which can measure a slip amount of a brake slip and a rope slip with good accuracy.SOLUTION: In a winding sheave 20 in which a main rope 16 is wound around, a marking device 30 for slip measurement for measuring a brake slip amount from the moment the brake is applied to the rotation of the winding sheave 20 to the stop of the winding sheave 20, and a rope slip amount from the stop of the winding sheave 20 to the stop of the main rope 16 includes: a detection unit 32 for detecting that the rotational speed of the winding sheave 20 has reached a predetermined speed, and for synchronizing and outputting a marking signal for adding a mark and a brake signal for inspection for operating the brake; and a stamp part 34 for adding a linear mark striding over the main rope 16 and the winding sheave 20 when th marking signal is output. |
