Control method for work machines, control program for work machines, control system for work machines, and work machines

Abstract

To provide a control method of a work machine, a control program of the work machine, a control system for the work machine, and the work machine capable of reducing time and effort of operation by an operator.SOLUTION: A control method of a work machine 3 is to select one motion mode from a plurality of motion modes including a crane mode for making a working part 33 carry out a suspension work, and another mode for making the working part 33 carry out the other work rather than the suspension work. The control method of the work machine 3 carries out a posture change operation for changing a posture of the working part 33 to a specific posture when the working part 33 is not in the specific posture upon change to the crane mode.SELECTED DRAWING: Figure 1

Claims

1. Used in a work machine comprising a traveling section having a traveling function and a working section configured to perform operations including lifting operations, Selecting one operating mode from a plurality of operating modes, including a crane mode in which the work unit performs the lifting operation, and a separate mode in which the work unit performs an operation other than the lifting operation, The operation to switch to the crane mode includes, if the working unit is not in a specific position, performing a position change process to change the working unit to the specific position before switching to the crane mode. The work section includes a first boom and a second boom connected to each other, and has a boom that can change the angle of the second boom relative to the first boom in a plan view. The posture of the work section changes depending on the angle of the second boom relative to the first boom. The aforementioned specific posture is the posture of the work unit when the first boom and the second boom are aligned in a straight line in a plan view. A method for controlling industrial machinery.

2. The system further includes performing a change restriction process that restricts changes in the posture of the work unit from the specific posture while the crane mode is in operation. A method for controlling a work machine according to claim 1.

3. In the change restriction process, the second boom is fixed to the first boom, A method for controlling a work machine according to claim 2.

4. When switching to the aforementioned crane mode, the attitude change process is executed if the predetermined permission conditions are met. A method for controlling a work machine according to any one of claims 1 to 3.

5. The work unit has a retractable hook used in the crane mode, The crane mode is determined to have been selected when the hook moves from the retracted state to the unretracted state. A method for controlling a work machine according to any one of claims 1 to 4.

6. A control method for a work machine according to any one of claims 1 to 5, A control program for a work machine to be executed by one or more processors.

7. Used in a work machine comprising a traveling section having a traveling function and a working section configured to perform operations including lifting operations, A selection processing unit that selects one operation mode from a plurality of operation modes, including a crane mode in which the work unit performs the lifting operation, and a separate mode in which the work unit performs an operation other than the lifting operation, The system includes a posture change processing unit that, if the posture of the work unit is not in a specific posture when switching to the crane mode, executes a posture change processing to change the posture of the work unit to the specific posture before switching to the crane mode, The work section includes a first boom and a second boom connected to each other, and has a boom that can change the angle of the second boom relative to the first boom in a plan view. The posture of the work section changes depending on the angle of the second boom relative to the first boom. The aforementioned specific posture is the posture of the work unit when the first boom and the second boom are aligned in a straight line in a plan view. Control system for industrial machinery.

8. A control system for a work machine according to Claim 7, The aforementioned travel unit, The work section comprises the above-mentioned work section, A type of machinery used for industrial work.
