Wire rope electric hoist reasons of gear wear

Wire rope electric hoist after using a period of time, the gears will wear.

Transmission gear for electric wire rope hoist on another failure form is abrasion,tooth wear after thinning. If the lubrication wear caused by impurities, commonly known as the abrasive wear. This wear often appear in the addendum and dedendumscraping together the very deep, scraping the road perpendicular to the pitch line and parallel to each other. After scraping the oil temperature crane series
