The damage and detachment of the rope guide may indeed lead to the malfunction of the electric hoist, and the specific impacts and reasons are as follows:

1、 The function of the rope guide

The rope guide is an important component in electric hoists, whose main function is to ensure that the steel wire rope is neatly arranged on the drum, prevent the steel wire rope from tangling and jumping, thus protecting the steel wire rope and drum from unnecessary wear and maintaining the normal operation of the electric hoist.

2、 The impact of damaged and detached rope guides

Wire rope failure:

Once the rope guide is damaged or detached, it will not be able to effectively guide the steel wire rope to align on the drum, resulting in the phenomenon of the steel wire rope running around (tangled around).

The tangled steel wire rope may lose its original arrangement order, causing the upper and lower limit positions to fail, which can lead to serious consequences such as the hook hitting and pulling the steel wire rope.

Electric hoist malfunction:

The failure of the steel wire rope will directly affect the lifting capacity of the electric hoist, and even cause the entire equipment to malfunction.

In serious cases, it may also cause safety accidents such as heavy object falls, posing a threat to personnel and property.

3、 Reasons for damage and detachment of the rope guide

Overloaded:

Overloading or overloading of electric hoists can cause excessive pressure on the rope guide, resulting in damage or destruction.

Material issues:

Some electric hoist rope guides have poor material quality and are prone to problems such as breakage and deformation over time.

Incorrect usage:

Abnormal usage methods such as overloading and prolonged continuous use can cause damage to the rope guide.

Illegal operations such as diagonal pulling and lifting can also cause excessive lateral tension on the rope guide, leading to its rupture.

Rust and corrosion:

The rope guide is prone to rusting and corrosion when exposed to damp, dusty, strong acid and other environments, which greatly reduces its service life.

Lack of regular maintenance:

If the electric hoist is not regularly inspected and maintained, it is easy to cause damage to the rope guide. For example, insufficient oil in the rope guide or failure to replace it for a long time can lead to mechanical failure.

4、 Preventive measures

Choose the appropriate electric hoist:

Choose an electric hoist suitable for the load based on the size, weight, and height of the object to be lifted, to avoid overloading or underloading.

Correct use of electric hoist:

Follow the operating procedures, do not use beyond the limit, and do not use continuously for too long.

Avoid illegal operations such as diagonal pulling and lifting, and ensure that the rope guide is not subjected to excessive lateral tension.

Regular maintenance and inspection:

Regularly clean and lubricate the hoist rope guide to extend its lifespan.

Timely replace worn parts and rope guide oil, etc.

Regularly inspect the installation and operation of the rope guide to ensure its proper functioning.

Keep the environment dry:

Electric hoists should be kept in a dry environment. If they need to be used in a humid environment, moisture-proof measures should be taken.
