When choosing a European steel wire rope electric hoist, a comprehensive evaluation should be conducted from four core dimensions: structure and strength, anti rotation and anti fatigue performance, lubrication and maintenance, and brand and specification adaptation. The specific selection method is as follows:

1、 Structure and strength: Priority should be given to choosing 8-strand surface contact steel ropes

Advantages of 8-strand steel rope:

European and American brands (such as Dipa, Casa, and Buton) often use the 8 × K26WS-EPIWRC structure, which increases the surface contact area between the steel wires with its special-shaped strand design, making the force distribution more uniform and reducing wear. Compared to 6-strand steel ropes, the 8-strand structure has a larger metal cross-sectional area at the same diameter, an increase in breaking force of about 20%, and stronger lateral load resistance, making it suitable for high load and frequent start stop working conditions.

Steel core coating technology:

It is recommended to choose steel wire rope coated with plastic (EPIWRC), whose plastic layer can form a molded buffer layer to avoid direct contact between the outer steel strands and the steel core, reduce the risk of "birdcage phenomenon", and block the infiltration of water and corrosive substances, extending the service life.

2、 Anti rotation and anti fatigue performance: multi strand structure adapts to complex working conditions

Anti rotation requirement:

In load-bearing or multi-layer winding systems, steel wire ropes are prone to rotating and winding due to torque, which affects work efficiency. The 8-strand steel rope belongs to a multi strand structure and naturally has anti rotation characteristics, which can reduce problems such as broken strands and knots, especially suitable for scenarios that require precise control such as high-rise building hoisting and bridge construction.

Anti fatigue design:

When the steel wire rope passes around the pulley or drum, bending fatigue is the main cause of damage. The 8-strand steel rope has better closure, stronger spatial stability, and can better withstand composite pressure. At the same working level, its fatigue life is about 30% longer than that of 6-strand steel rope.

3、 Lubrication and maintenance: Stock coating oil process reduces long-term costs

Comparison of lubrication methods:

Domestic steel ropes often use rope coating with oil, which has a thick surface oil layer and is prone to dripping, resulting in insufficient internal lubrication; European brands, such as Germany's Nierosden and Volkswagen Lubricants, use a stock coating process to spray specialized grease at high temperatures during production, forming a semi dry thin oil layer with strong permeability and excellent anti-corrosion performance. It is not easy to dilute and drip at high temperatures, which can reduce grease splashing and adhesion of frictional particles, and lower maintenance frequency.

Maintenance suggestion:

Regularly check the winding condition of the steel wire rope on the drum to avoid overlapping or crossing; After a period of use, the worn section fixed on the drum can be cut off, and the parts in good condition can be moved to the high-frequency use area to extend the overall service life.

4、 Brand and specification adaptation: Choose based on job level and load requirements

Brand recommendation:

High end scenario: Choose German brands such as Dipa, Casa, or Italian brands such as Nai Deli, whose 8-strand steel rope has a minimum breaking force of up to 1960~2160kN, suitable for heavy-duty tasks of M6 and above working levels.

Cost sensitive scenario: Korean brands such as Rongxing and DSR offer lower prices for 6-strand steel ropes, but it is necessary to ensure that their specifications meet the minimum safety factor requirements (such as GB/T 13752-1992 standard).
