Abstract
A remote operation terminal T for remotely operating a mobile crane C is configured to include: a mode selection unit 34 for selecting an operation mode corresponding to work of the mobile crane C from a plurality of operation modes; an operation unit 35, 36 for instructing the mobile crane C on operation; and a control unit T1 that, when the operation mode is selected by the mode selection unit 34, assigns the operation corresponding to the selected operation mode to the operation unit 35, 36, and transmits an operation signal from the operation unit 35, 36 to the mobile crane C. Thereby, various operations can be performed by remote operation while securing safety.
Claims9
A remote operation terminal for remotely operating a mobile crane, comprising:
- a mode selection unit that can select an operation mode corresponding to work of the mobile crane from a plurality of operation modes;
- an operation unit for instructing the mobile crane on operation;
- and
- a control unit that, when the operation mode is selected by the mode selection unit, transmits a signal indicating the operation mode selected by the mode selection unit to the mobile crane, assigns the operation corresponding to the selected operation mode to the operation unit, and transmits an operation signal from the operation unit to the mobile crane,
- wherein when the operation mode is selected, an operating range of a boom that can be performed from the remote operation terminal is limited to a limited movable range corresponding to the selected operation mode and set in the mobile crane, and
- wherein in the selected operation mode, the limited movable range is smaller than an operation range of the boom in which instruction can be performed from a cab operation device of the mobile crane.
A remote operation system of a mobile crane comprising:
- a mobile crane including a boom;
- a remote operation terminal comprising:
- a mode selection unit that can select an operation mode corresponding to work of the mobile crane from a plurality of operation modes;
- an operation unit for instructing the mobile crane on operation;
- and
- a control unit that, when the operation mode is selected by the mode selection unit, transmits the signal indicating the operation mode selected by the mode selection unit to the mobile crane, assigns the operation corresponding to the selected operation mode to the operation unit, and transmits an operation signal from the operation unit to the mobile crane;
- an overload prevention device that is provided in the mobile crane, has a plurality of limited movable ranges, and sets the operating range of the boom to the limited movable range corresponding to an operation mode corresponding to the signal received from the remote operation terminal,
- wherein when the operation mode is selected in the remote operation terminal, an operating range of the boom that can be performed from the remote operation terminal is limited to a limited movable range corresponding to the selected operation mode, and
- wherein in the selected operation mode, the limited movable range is smaller than an operation range of the boom in which instruction can be performed from a cab operation device of the mobile crane.
