PROBLEM TO BE SOLVED: To provide an external power source determination device of a work machine capable of allowing an operator to recognize whether the work machine can be driven or not before start of work by the power of the external power source.SOLUTION: It is determined whether a crane device 20 can be driven by an external power source or not, based on a detection voltage by a voltage sensor 52, and the determination result is displayed on a display device 53. Thereby, since possibility of driving of the crane device 20 by the external power source can be reported before operation of work by an operator, work efficiency can be improved and generation of a failure can be reduced. |
