The three typical situations in which the rope guide of an electric hoist is prone to damage during operation are as follows:

Specification mismatch

Mismatch between steel wire rope and drum rope groove: If the steel wire rope is not replaced with a product that is consistent with the specifications of the drum rope groove, it will cause the steel wire rope to not wrap correctly, intensify the friction between the rope guide and the steel wire rope, and cause wear or breakage of the rope guide after long-term use.

Mismatch between rope guide and equipment model: Non original or poorly adapted rope guides may not be able to work in conjunction with the drum and steel wire rope due to structural size deviations, resulting in operation jamming or uneven force distribution, and ultimately damage.

Irregular operation

Diagonal pulling and lifting: When the electric hoist is not in a vertical plane with the cargo, the steel wire rope will apply lateral squeezing pressure on the rope guide, causing it to shift or deform. This operation will damage the limit function of the rope guide, causing the up/down limit to move forward or backward, and even causing the rope guide to break.

Frequent tapping and emergency stop: Such operations can generate impact loads, accelerating the fatigue damage of the rope guide. For example, when the steel wire rope suddenly experiences force during an emergency stop, it may directly pull and tug on the rope guide, causing damage to its structure.

Maintenance and installation issues

Improper installation: If the rope guide is not aligned with the axis of the drum, or if the gap adjustment is too large/too small, it will cause the steel wire rope to be squeezed or detached from the track, increasing the risk of rope guide wear. For example, a small gap may cause the steel wire rope to get stuck between the rope guide and the drum, resulting in compression deformation of the rope guide.

Insufficient maintenance: Long term failure to inspect the wear or cracks of the rope guide, or failure to replace worn rope guides in a timely manner, can lead to the expansion of damage. For example, if the surface of the rope guide shows cracks and continues to be used, it may suddenly break due to concentrated force.

Lack of lubrication: Lack of oil in the friction area between the rope guide and the steel wire rope will exacerbate wear and shorten its service life. Especially in high temperature and dusty environments, insufficient lubrication can accelerate the corrosion or jamming of the rope guide.
