Claims (1)
ーンが同一方向に走行可能な走行レールを固設し
、上記各クレーンが、上記走行レールを走行して
所定の作業を行う際の走行安全装置であつて、上
記走行レールもしくは各クレーンに設けられ、該
レールの長さ方向を略等間隔に分けた各位置で、
各クレーンの位置を検出して、その検出信号を出
力する位置検出手段と、各クレーンに設けられ、
隣合うクレーンの間隔が所定間隔内にあるか否か
を感知し、それをＯＮ―ＯＦＦ信号で出力可能な
感知手段と、上記位置検出手段からの信号が出力
された際に、上記感知手段からの信号がＯＮ状態
にある時、上記隣合う両クレーンを停止させる、
もしくは所定間隔外に移動させるべく少なくとも
一方のクレーンを駆動制御する制御手段とを備え
たことを特徴とするクレーン走行安全装置。 A traveling rail is fixedly installed on which a plurality of cranes each having a holding part capable of holding a workpiece can travel in the same direction, and each of the cranes is a traveling safety device when traveling on the traveling rail and performing a predetermined work. provided on the traveling rail or each crane, at each position divided at approximately equal intervals in the length direction of the rail,
A position detecting means for detecting the position of each crane and outputting a detection signal, and a position detecting means provided on each crane,
a sensing means capable of sensing whether the distance between adjacent cranes is within a predetermined distance and outputting it as an ON-OFF signal; When the signal is ON, stop both of the adjacent cranes.
or a control means for driving and controlling at least one crane so as to move it outside a predetermined interval.
