起重机小车运行供电用电缆是起重机的重要电气部件之一,它的功效如何将直接影响起重机的安全、可靠。起重机运行机构供电的方式有多种,最常用的可归结为两大类,即硬滑线供电和软电缆供电。硬滑线中的角钢平面导电较笨重,易积灰、积水、积冰等,影响 Crane running power cable is one of the important electrical components of the crane, how its effectiveness will directly affect the crane’s safety and reliability. Crane operating agencies have a variety of ways of power supply, the most commonly used can be attributed to two broad categories, namely hard-slip line power supply and soft-cable power supply. Hard slippery in the angle of the plane conductive more bulky, easy to foul, water, ice, etc., the impact
