reeling cable for excavator

Corkscrewing — also referred to as Z-kinking or the “pigtail” effect — is among the most frequently encountered failure modes in dynamic reeling applications. When a Type 440 cable repeatedly exhibits helical deformation after even modest operating hours, the root cause almost never lies in a single variable. It is instead a compounding interaction of design, installation, and operating conditions. （软电缆在卷盘运行中出现螺旋变形，通常称为”软木塞效应”或Z型褶皱，是Type 440型动态卷盘电缆最常见的失效模式之一。）
