To provide a load display device for a work machine capable of improving display accuracy of a load value of a suspended load.SOLUTION: There are included a load cell 2 for detecting a load value of a suspended load, a rotation detection sensor 3 provided on at least one of an upper spreader 30 and a lower spreader 18 to detect the rotation of a sheave 40, a display device, and display control means for displaying the load value of the suspended load on the display device. The display control means does not cause the display device to display the load value of the suspended load detected by the load cell 2 during a period from when a boom hoisting winch 36 is driven to when the rotation detection sensor 3 detects the rotation of the sheave 40.SELECTED DRAWING: Figure 2

    【課題】吊荷の荷重値の表示精度を向上させることが可能な作業機械の荷重表示装置を提供する。【解決手段】吊荷の荷重値を検出するロードセル2と、上部スプレッダ30および下部スプレッダ18の少なくとも一方に設けられ、シーブ40の回転を検出する回転検出センサ3と、表示装置と、吊荷の荷重値を表示装置に表示させる表示制御手段と、を有する。表示制御手段は、ブーム起伏用ウインチ36が駆動されてから回転検出センサ3がシーブ40の回転を検出するまでの間にロードセル2が検出した吊荷の荷重値を、表示装置に表示させない。【選択図】図2
