PROBLEM TO BE SOLVED: To determine normal/abnormal of an abrasion amount of a sheave groove easily even when interval between a sheave and a motor side surface is small.SOLUTION: A sheave groove measurement device includes: a support body 3 which comes into contact with a mountain part 1e formed between sheave grooves 1a, 1b, 1c and which is installed so as to stride over a main rope 2 mounted in the sheave grooves 1a, 1b, 1c; and a caliper part 4 which is supported by the support body 3 via a gap part connected in a detachable manner by fitting and which measures a projection amount of the main rope 2 from the sheave grooves 1a, 1b, 1c while being supported by the support body 3. On the support body 3 side, fitting parts 3a, 3b are provided fitted with the caliper part 4 in a direction orthogonal to or parallel with the sheave grooves 1a, 1b, 1c. The caliper part 4 is fitted with the first fitting part 3a pair at a central part of the support body 3 in the direction orthogonal to the sheave groove 1b, and fitted with the second fitting part 3b pair on one end part 30c side of the support body 3 in the direction parallel with the sheave grooves 1a, 1c. |
