Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a radio control forget warning device for a crane truck that warns that a crane has been forgotten to be stored in a truck with a crane and that a radio control has been forgotten.

[0002]

[Prior art]

 Conventionally, when attempting to start a truck with the boom of a derrick crane incompletely stored, the driver is warned with a warning buzzer or warning lamp to prevent the danger of forgetting to store the crane. This is known from, for example, JP-A No. 59-114295. These items are only intended to prevent the danger of the crane caused by the truck running after the crane operation processing.On the other hand, the radio control for operating the crane is a necessity, but if the crane is left on the site, the crane must be installed at the next site. Although it could not be moved, there was no warning device for forgetting to carry the radio control.
