In FIG. 1, reference numeral 1 denotes a housing portion of the radio signal transmitter 3, and the housing portion 1 is arranged at a driver's seat of a vehicle of a self-propelled crane or at an appropriate position of a hydraulic crane. Reference numeral 2 denotes an accommodation detection switch which detects that the radio signal transmitter 3 is not accommodated in the accommodation section 1. In this example, the accommodation detection switch 2 is a switch that is in contact when not accommodated and disconnected when accommodated. Four
Is a mission switch associated with the operating lever 5 for shifting the mission (not shown), and detects when the operating lever 5 is shifted from the mission neutral position. In this example, the switch is a switch that comes into contact when the operation lever 5 is operated to the mission shift position. Reference numeral 6 denotes an alarm device. In the electric circuit of the alarm device 6, the accommodation detection switch 2 and the mission switch 4 are provided in series. Incidentally, 7 is a power source.

Next, the operation will be described. In the crane work state in which the operation lever 5 is operated to the mission neutral position, the mission switch 4 is turned off. Therefore, even if the radio signal transmitter 3 is taken out from the housing portion 1 and the hydraulic crane is remotely operated,
The alarm device 6 does not operate. However, when the crane work is completed and the operation lever 5 is set to the mission shift position, the mission switch 4 is brought into contact with the housing. Therefore, if the radio signal transmitter 3 is not housed in the housing portion 1 in this state, the housing detection switch 2 is brought into contact. Since the alarm 6 is activated,
It alerts the operator. Therefore, the accident of leaving the wireless signal transmitter at the work site is prevented in advance.

In the above embodiment, the switches 2 and 4 are connected to the alarm device 6.
I showed an example that it was configured by inserting in series in the electric circuit of
It is needless to say that a single switch that is operated to be connected or disconnected according to the operating states of the switches 2 and 4 may be provided in the electric circuit of the alarm device. In short, the accommodation detection switch 2
The non-accommodation of the radio signal transmitter 3 in the accommodating portion 1 may be detected by disconnection or contact, and the mission switch 4 may detect the shift from the neutral position of the mission by contact or disconnection. , These switches are associated with each other in the electric circuit of the alarm device 6, the accommodation detection switch 2 detects the non-accommodation of the radio signal transmitter 3 in the accommodation portion 1, and the mission switch 4 shifts from the neutral position of the mission. The alarm device 6 may be configured to operate when it is detected.
