To provide a traveling state detection device and a work machine comprising the same which can make the work machine safely travel on a plate-like member even when an upper structure rotates.SOLUTION: A traveling state detection device includes: a pair of sensors 2 disposed in a longitudinal direction of an upper structure 12 and capable of detecting a ladder-like member 30; and a controller determining whether a travel crawler 15 travels on the ladder-like member 30 on the basis of detection results. The pair of sensors 2 includes a plurality of non-contact type distance measuring sensors 3 disposed on a lower face of the upper structure 12 and outputs an output value according to distance to a detection object. When the travel crawler 15 travels on the ladder-like member 30 and in a case where one of distance measuring sensors 3 of the pair of sensors 2 can detect the ladder-like member 30, the controller specifies the distance measuring sensor 3 on the basis of the output value outputted by each of the distance measuring sensors 3 and determines whether there is a possibility of stepping out from the ladder-like member 30 by the travel crawler 15 on the basis of a change of the output value of the distance measuring sensor 3.SELECTED DRAWING: Figure 2

    【課題】上部旋回体が旋回しても、板状部材の上で作業機械を安全に走行させることが可能な走行状態検出装置、および、これを備えた作業機械を提供する。【解決手段】上部旋回体12の左右方向に配置され、梯子状部材30を検出可能な一対のセンサ2と、検出結果に基づいて、走行クローラ15が梯子状部材30の上を走行しているか否かを判定するコントローラと、を有する。一対のセンサ2は、上部旋回体12の下面に配置された複数の非接触型の測距センサ3を有し、検出物との距離に応じた出力値を出力する。走行クローラ15が梯子状部材30の上を走行する際に、一対のセンサ2の測距センサ3のいずれかが梯子状部材30を検出可能である場合に、コントローラは、測距センサ3の各々が出力する出力値に基づいて測距センサ3を特定し、測距センサ3の出力値の変化に基づいて、走行クローラ15が梯子状部材30を踏み外す可能性があるか否かを判定する。【選択図】図2
