To provide a crane operation meter, and a crane maintenance and service method for managing an integrated value of the number of operations, operation time, and a moving distance for the lifted load value, and for grasping the replacement cycle and the timing of the next replacement for each component part of the crane.SOLUTION: A crane operation meter has a load measuring device part to detect the load value of a crane suspended load. The crane operation meter has a lifting integrated number meter which divides and segments the range from 0 t to a rated load into load ranges WP at certain intervals, measures the load every time the crane operates in the lifting direction, temporally stores the maximum load value from the measured load value, adds the lifting integration count once to the divided segment of the load range to which the maximum measured load value belongs when unloading a suspended load, resets the maximum load value, and performs remeasurement. Furthermore, the crane operation meter has the function to add cumulatively the operation time and moving distance measured at that time to an integration time meter and integration distance meter in the load range segment to which the measured load value during the operating in the winding up/down direction belongs.SELECTED DRAWING: Figure 2

    【課題】吊り上げた荷重値に対する稼働回数、稼働時間と移動距離の積算値を管理し、クレーンの各構成部品の交換周期と次回の交換時期を把握するためのクレーン稼働計及びクレーンの保守サービス方法を提供すること。【解決手段】クレーンの吊荷の荷重値を検出する荷重計測装置部を有し、クレーンの0tから定格荷重までの間をある間隔の荷重範囲WPに分割区分し、クレーンが巻上げ方向に動作する度に荷重計測を行い、計測された荷重値から最大荷重値を一時記憶し、吊荷を下ろした時に、前記の計測された最大荷重値が属する荷重範囲の分割区分に吊り上げ積算回数を1回積算加算するとともに最大荷重値をリセットし再計測を行う吊り上げ積算回数計を有し、更に巻上げ方向及び巻下げ方向に動作中に測定した荷重値が属する荷重範囲区分の積算時間計と積算距離計に、その時に測定した動作時間と移動距離を積算加算する機能を有する。【選択図】図2
