パックホーン８、バックランプ９に接続した第１開閉ス
イツチ１１との間に設けられ、Ｂ接点６２は電源７とパ
ックホーン８、バックランプ９に接続した第２開閉スイ
ツチ１０との間に設けである。The contact 5a of the limit switch 5 is provided in the power supply circuit of the coil 6a of the relay 6, and when the contact 5a is turned on, the A contact 61 of the relay 6 is turned on. The B contact 62 is provided between the power source 7 and the first open/close switch 11 connected to the pack horn 8 and back lamp 9, which act as backward indicators to signal that the vehicle is going backwards from the operator's perspective. It is provided between the horn 8 and a second open/close switch 10 connected to the back lamp 9.
なお、パックホーン８、バックランプ９は従来と同様に
上部旋回体２の後部に設けである。Note that the pack horn 8 and the back lamp 9 are provided at the rear of the revolving upper structure 2 as in the conventional case.
前記リミットスイッチ５の接点５ａは上部旋回体２が図
示の旋回位置の時にＯＦＦ、図示位置よ９１８０度の旋
回位置の時にはＯＮとなり、第２開閉スイツチ１０は前
後進レバ３を（矢印へ方向）に操作するとＯＮ、第１開
閉スイツチ１１は前後進レバ３を（矢印は方向）に操作
するとＯＮとなるように構成しである。The contact point 5a of the limit switch 5 is turned OFF when the upper revolving body 2 is in the illustrated turning position, and turned ON when the upper rotating body 2 is in a turning position 9180 degrees from the illustrated position, and the second opening/closing switch 10 turns the forward/backward lever 3 (in the direction of the arrow). The first opening/closing switch 11 is configured to be turned on when the forward/reverse lever 3 is operated in the direction indicated by the arrow.
しかして、図示の状態で前後進レバ３をへ方向に操作す
ると第２開閉スイツチ１０がＯＮとなってパックホーン
８、バックランプ９が動作し車両後進を表示する。When the forward/reverse lever 3 is operated in the direction shown in the figure, the second opening/closing switch 10 is turned on and the pack horn 8 and back lamp 9 are operated to indicate that the vehicle is moving backward.
また、上部旋回体２を１８０度旋回した旋回位置とする
とカム４によってリミットスイッチ５の接点５ａがＯＮ
となり、Ａ接点６□がＯＮとなるので、前後進レバ３を
（矢印は方向）に操作すると第１開閉スイツチ１１がＯ
Ｎとなりパックホーン８、バックランプ９が動作すると
共に、下部走行体１は（矢印ち方向）に走行し車両はオ
ペレータＯｐから見て後進する。Furthermore, when the upper revolving body 2 is at the rotating position of 180 degrees, the contact 5a of the limit switch 5 is turned ON by the cam 4.
Therefore, the A contact 6□ is turned ON, so when the forward/reverse lever 3 is operated in the direction indicated by the arrow, the first open/close switch 11 is turned ON.
N, the puck horn 8 and the back lamp 9 operate, the lower traveling body 1 runs in the direction of the arrow, and the vehicle moves backward as seen from the operator Op.
したがって、オペレータＯｐから見て車両が後進する時
にはパックホーン８、バックランプ９は動作し後進を表
示する。Therefore, when the vehicle is moving backwards as seen from the operator Op, the pack horn 8 and the back lamp 9 operate to indicate that the vehicle is moving backwards.
本考案は以上の様になり、上部旋回体２が１８０度旋回
