To provide a surroundings monitoring device for work machines that can allow workers to easily determine contact between a revolving superstructure and obstacles when an undercarriage travels.SOLUTION: The surroundings monitoring device for work machines comprises: an advance direction detection device that detects an advance direction of an undercarriage; a revolving angle detection device that detects a revolving angle of a revolving superstructure with respect to the undercarriage; an imaging device that is provided on the revolving superstructure and images surroundings of the revolving superstructure; a display 5 that is provided in an operator cab; display control means that displays an image captured by the imaging device on the display 5; and rear end trajectory calculation means that calculates an expected movement trajectory of a rear end of the revolving superstructure as a rear end trajectory 11 based on the advance direction of the undercarriage detected by the advance direction detection device and the revolving angle of the revolving superstructure detected by the revolving angle detection device when the undercarriage travels. The display control means displays the rear end trajectory 11 calculated by the rear end trajectory calculation means on the display 5 by being superposed on the image captured by the imaging device.SELECTED DRAWING: Figure 4

    【課題】下部走行体の走行時における上部旋回体と障害物との接触を作業者に判断させやすくすることが可能な作業機械の周囲監視装置を提供する。【解決手段】下部走行体の進行方向を検出する進行方向検出装置と、下部走行体に対する上部旋回体の旋回角度を検出する旋回角度検出装置と、上部旋回体に設けられ、上部旋回体の周囲を撮像する撮像装置と、運転室内に設けられたディスプレイ5と、撮像装置が撮像した画像をディスプレイ5に表示させる表示制御手段と、下部走行体が走行している場合に、進行方向検出装置が検出した下部走行体の進行方向と、旋回角度検出装置が検出した上部旋回体の旋回角度とに基づいて、上部旋回体の後端の予想される移動軌跡を後端軌跡11として算出する後端軌跡算出手段と、を有する。表示制御手段は、後端軌跡算出手段が算出した後端軌跡11を、撮像装置が撮像した画像に重畳させてディスプレイ5に表示させる。【選択図】図4
