摘要： A ROPS (protective structure) (15) is obtained by coupling upper ends of a pair of leg portions (15a) with a coupling portion (15b) and forming an arc-shaped curved portion (15c) between each of the leg portions (15a) and the coupling portion (15b), and is arranged so as to straddle vehicle bodies (4 and 5) and fixed. A working light (17) is fixed to the left curved portion (15c) via a mounting bracket (19), and a rotary light (18) is detachably mounted by fixing a mounting bracket (20). A protect region (E) formed into an approximately triangular shape is formed by the curved portion (15c) of the ROPS (15), a lateral restriction line (L1) in which a left-side surface corresponding to a maximum width of the vehicle bodies (4 and 5) is extended upward and an upper restriction line (L2) in which a maximum height of the ROPS (15) is extended laterally. The working light (17) and the mounting brackets (19 and 20) are arranged in the protect region (E), thereby preventing an outward protrusion.

摘要： An object of the present invention is to provide a monitoring system, a monitoring device, and a construction machine each capable of improving the convenience for a user during monitoring while ensuring security related to the leakage of video data of a peripheral region. In a monitoring system 10 of the present invention, a monitoring device 30 reads information related to an access ID from a first authentication-related information display portion 208 arranged outside an operator's cab of a construction machine 20, using a second camera 300, and also reads information related to an access password from a second authentication-related information display portion 210 arranged in the operator's cab, using the second camera 300. The access ID may include a combination of the identification number of the construction machine 20 and a code representing the type of the construction machine 20.
