PROBLEM TO BE SOLVED: To detect deterioration in a hydraulic hose of a fork lift.SOLUTION: The fork lift includes: the hydraulic hose where an electrical line is disposed in the inner layer thereof; a current detection part for detecting a current flowing through the electrical line; and a deterioration estimation part for detecting deterioration in the hydraulic hose based on if the current detection part detects a current.SELECTED DRAWING: Figure 1
【課題】フォークリフトの油圧ホースの劣化を検出する。【解決手段】フォークリフトは、内層に電線が配された油圧ホースと、電線に流れる電流を検出する電流検出部と、電流検出部が電流を検出したか否かに基づいて、油圧ホースの劣化を推定する劣化推定部とを備える。【選択図】図1
