Embodiment

[0021] (constitute)

[0022] First, use figure 1 The overall configuration of the mobile crane including the remote operation device 40 for actuators, that is, the rough terrain crane 1 of this embodiment will be described. In the following embodiments, the rough terrain crane 1 will be described as an example of a mobile crane to which the present invention is applied, but the invention is not limited thereto, and the present invention can be widely applied to mobile cranes such as all-terrain cranes.

[0023] (The overall composition of the crane)

[0024] Such as figure 1 As shown, the off-road crane 1 of this embodiment includes: a vehicle body 10 having a traveling function and serving as the main body of the vehicle, outriggers 11 provided at the four corners of the vehicle body 10, ... The rotating platform 12 and the boom 14 mounted on the bracket 13 , wherein the bracket 13 is erected on the rotating platform 12 .

[0025] Outrigger 11 can pass through slide cylin...

Abstract

The invention discloses an operating machine capable of remote operation and ensuring safety; the operating machine is configured to be capable of communicating with a remote operating device (40), and is provided with a communication unit (70a), (40) receiving an operation signal; and a control unit (70) that controls an actuator (51) mounted on the work machine based on the operation signal from a main operation device or a remote operation device (40) disposed in a cab of the work machine. -59) control, the control unit (70) does not allow remote operation of at least one actuator (51-59) through the remote operation device (40) when the state of the working machine does not meet the predetermined condition.

Description

technical field [0001] The invention relates to a working machine. Background technique [0002] Conventionally, in work machines such as mobile cranes, a remote operation device for operating an actuator from the outside of a cab has been proposed. In addition, a technology has also been developed in which an auxiliary operation panel connected to the control unit by wire is provided independently of the main operation device arranged in the cab, and the auxiliary operation panel can be switched during work that is difficult to confirm from the cab. to the auxiliary operation panel to operate the actuator. [0003] For example, Patent Document 1 discloses an operating device configured so that it can be controlled by an auxiliary operating panel only when the overload prevention device is set to the boom extending or retracting mode, and the controllable range is limited to Perform boom extension or retraction within the range of crane motion required. [0004] prior art...
