PROBLEM TO BE SOLVED: To provide a measuring apparatus for load of an operating machine easy to operate and high in convenience.SOLUTION: A measuring apparatus for load of an operating machine comprises: a lifting machine 24 for lifting a load; a hydraulic actuator 42 driving the lifting machine 24; a hydraulic circuit 30 for supplying a hydraulic oil to the hydraulic actuator 42; a pressure sensor 36 for measuring the driving pressure of the hydraulic actuator 42; and a controller 28. The controller 28 defines the flow of the hydraulic oil supplied to the hydraulic actuator 42 as a prescribed flow and converts the output of the pressure sensor 36 into a load value. Since the controller 28 defines automatically the flow of the hydraulic oil supplied to the actuator 42 as the prescribed flow, the operations of zero point adjustment and flow adjustment are unnecessary and thus, the measuring apparatus exerts high convenience.SELECTED DRAWING: Figure 1
【課題】操作が簡単で、利便性の高い作業機の荷重測定装置を提供する。【解決手段】荷を揚げる揚重機24と、揚重機24を駆動する油圧アクチュエータ42と、油圧アクチュエータ42に作動油を供給する油圧回路30と、油圧アクチュエータ42の駆動圧力を測定する圧力センサ36と、制御装置28とを備え、制御装置28は油圧アクチュエータ42に供給される作動油の流量を所定流量とし、圧力センサ36の出力を荷重値に変換する。制御装置28が油圧アクチュエータ42に供給される作動油の流量を自動的に所定流量とするので、ゼロ点調整や流量調整の操作が不要であり、利便性が高い。【選択図】図1
