Bridge crane monitoring system

A bridge crane monitoring system for monitoring a bridge crane (1) provided with a traveling body (2) that travels along a track (4), a cross carriage (3) that travels along the traveling body (2) in a direction orthogonal to the traveling direction of the traveling body (2), and a winding device (5) that is mounted on the cross carriage (3). A bridge crane monitoring system is provided with: an imaging device, i.e., a camera (6), which is provided on a traveling body (2), and which is capable of changing the imaging direction and zooming; and a control device (100) that, on the basis of the image captured by the imaging device (6), controls the imaging device (6) so as to track and image the sling (5a) lifted by the winding device (5), whereby it is possible to provide an operator with an image suitable for ascertaining the state of the sling (5a) and the lifted cargo of the overhead crane (1). 一种桥式起重机监视系统，用来对桥式起重机(1)进行监视，所述桥式起重机(1)具备沿着轨道(4)行进的行进体(2)、沿着行进体(2)而在与行进体(2)的行进方向正交的方向上行进的横行台车(3)、及搭载于横行台车(3)的卷起装置(5)
