Therefore, the controller (not shown) and the electrical connection device is disposed inside. As described above, a battery (not shown) is coupled to the bucket 110 to operate the controller and charge the equipment.

Since the connection between the bucket 110 and the boom assembly 100 requires insulation, the charging connection should be released when the battery is charged and the work is started again while the aerial work is stopped.

Therefore, according to the concept of the present invention, the charging receiver 121 is disposed on the end boom 120 and the charging transmitter 131 is disposed on the fixed boom 130 so that the charging operation can be automatically activated and released Is presented. More specifically, the charging receiver 121 is disposed at the lead-out end of the end boom 120, that is, adjacent to the connection portion with the bucket, and the charging transmitter 131 is disposed on the fixed boom 130. Therefore, when the boom assembly 100 is fully retracted, the charging receiver 121 and the charging transmitter 131 are electrically connected to each other to start the charging operation.

The charging receiver 121 and the charging transmitter 131 are formed to protrude from each other so as to be in contact with each other, the length is determined according to the number and arrangement of the expansion and contraction boom 140 interposed therebetween.

The charge receiving unit 121 is electrically connected through a battery and wires disposed in the bucket 110, the charge transmitting unit 131 is connected to a battery or a generator of the vehicle body itself to charge the charge receiving unit 121 Supply power.
