Electric hoist rope wear

In general, the rope is more commonly used in mechanical power transmission components of a flexible, in  Hoist equipment  with electric  lift hoist ,  hook together make up the transmission system, as the main part of the force, its specifications, load many as Yi consumable parts, and understanding the reasons causing the wear, it helps our routine maintenance, extend its life and reduce accidents. Wear is the most common injury rope phenomenon, generally divided into external wear, deformation wear and internal wear three kinds of circumstances, let's have introductions:

1, the external wear lubrication
Rope during use with pulley groove,load chain drum wall, hook and other surfaces in contact resulting in rope diameter will become thin, fine steel outer peripheral surface being polished, so bear the load of the wire cross-sectional area decreases, the load rope down . Wear a single week than the whole week actually wear more serious decline in its load caused abrasion than 30% higher for the week, so in the course of the week to keep the rope wear.
2, deformation wear
Wear is localized deformation wear a rope in the phenomenon, usually by vibration, collision and other causes. Such as wire rope on the drum by the impact, the process of lifting rope wrapped, knotted, or center of gravity caused by the bite rope pulley will cause deformation wear. Should be noted that during the operation to prevent this phenomenon, prolong life rope.
3, internal wear
Internal wear is the rope during operation, the different stocks friction between the wire, resulting in the case of an internal wire wear, usually with wire internal wear the number of shares, the degree of bending of wire rope, wire rope running speed, internally lubricated rope status.
