An informing device is an informing device mounted on a work vehicle that includes a lower base body, and a swivel body swivelably provided at the lower base body. The informing device includes a first detection unit that detects the actual amount of rotation of a drive device which swivels the swivel body or a driven part driven by the drive device, and a notification unit that issues a notification regarding information corresponding to the amount of rotation detected by the first detection unit.

Informing device, work vehicle, and informing method

A remote operation terminal T for remotely operating a mobile crane C is configured to include: a mode selection unitfor selecting an operation mode corresponding to work of the mobile crane C from a plurality of operation modes; an operation unitfor instructing the mobile crane C on operation; and a control unit Tthat, when the operation mode is selected by the mode selection unit, assigns the operation corresponding to the selected operation mode to the operation unit, and transmits an operation signal from the operation unitto the mobile crane C. Thereby, various operations can be performed by remote operation while securing safety.

Remote operation terminal and remote operation system of mobile crane

A working vehicle configured to raise and lower one of a jib and a boom by using a wire rope wound around a winch, the working vehicle includes: a detection part provided on one of the jib and the boom and configured to detect an angle of one of the jib and the boom controlled to be raised and lowered to determine whether or not an overload detection condition occurs or to perform overload prevention control; an acquisition part configured to acquire the angle of one of the jib and the boom controlled to be raised and lowered, based on a feed length of the wire rope; and a determination part configured to determine that a failure occurs when a difference between the angle detected by the detection part and the angle acquired by the acquisition part exceeds a predetermined tolerance.

Working vehicle

When an extension pattern selection device is activated, a normal mode is displayed on a screen of a monitor. An operator presses a manual mode switch key of an operation unit to switch the display mode of the screen from the normal mode to an extension pattern manual rearrangement mode. In the extension pattern manual rearrangement mode, the operator rearranges extension patterns so that frequently selected extension patterns P may be displayed at upper positions. Thus, the frequently selected extension patterns P are more preferentially displayed than the other extension patterns P.
