通常看到電纜卷筒的外表表皮會出現斷裂，毛糙的現象或者外表表皮沒有開裂但是內部護套絕緣層出現了這樣的問題，起重機電纜卷筒故障，通過觸摸可以發發現不平滑等觸感，有漏電現象，跳閘和停機。這就說明您的電纜已經出現了機械損傷。或老化。彎曲半徑超出推薦值當電纜彎曲或卷曲半徑小于制造商推薦的彎曲半徑值得時候，電纜會出現越扭越緊，很快就會出現表皮扭曲，糾結，徐州起重機電纜卷筒，打結，破損。

電纜卷盤由以下部分組成：卷盤式電纜卷盤、集電箱、減速器、磁滯耦合和變頻電機。其中，變頻電機配有電磁制動器、測速編碼器和風扇。滯后耦合在正常的電纜抽出和電纜敷設中不起作用。當發生故障時，如果電纜張力超過設定的力矩值而打滑，則起到保護作用。放纜進程是經過單向聚散設備，動力不能傳給耦合器和卷筒，在電纜拉力效果下，起重機電纜卷筒廠商，卷筒克服放纜磁滯器的滯動效果，同步放電纜。該電纜卷筒按動力系統方式可分為有動力型和無動力型2種。
