The requirements for fixing steel wire ropes in electric hoists mainly involve safety, stability, and durability. Here are some key fixed requirements:

1. Selection of steel wire rope

Type selection: Wire contact steel wire rope should be preferred due to its high fatigue strength, long service life, and high load-bearing capacity, which are superior to point contact steel wire rope.

Quality inspection: Ensure that the selected steel wire rope meets relevant standards, such as EN 12385-1 (although this standard has been abolished, new standards such as EN 12385-1+A1-2008 will still include similar requirements).

2. Design of fixed devices

Fixing method: The fixing method of the steel wire rope in the electric hoist should ensure firmness and reliability, and prevent loosening or falling off. Common fixing methods include pressure plate fixing, wedge block fixing, etc.

Strength requirement: The fixing device should be able to withstand the maximum tension of the steel wire rope and maintain sufficient strength and stability during use.

3. Installation and commissioning

Installation specifications: Install according to the installation instructions and specifications provided by the manufacturer, ensuring that the direction and fixed position of the steel wire rope meet the design requirements.

Pre tightening force: When fixing the steel wire rope, appropriate pre tightening force should be applied to ensure that the steel wire rope remains tight during use, reducing vibration and wear.

Debugging and inspection: After installation, debugging and inspection should be carried out to ensure that the fixing device of the steel wire rope is running normally, without looseness, abnormal noise, and other phenomena.

4. Maintenance and upkeep

Regular inspection: Regularly inspect the steel wire rope and its fixing device, including wear and tear, the degree of fastening of the fixing device, etc.

Lubrication and maintenance: Regularly lubricate and maintain the parts that require lubrication to reduce friction and wear.

Replacement standard: When the steel wire rope is severely worn, broken, or meets the specified replacement standard, it should be replaced in a timely manner.

5. Safety requirements

Emergency braking: The electric hoist should be equipped with an emergency braking device to ensure that it can quickly stop running in emergency situations and prevent accidents caused by wire rope breakage or detachment.

Limit device: A limit device should be installed to restrict the travel range of the electric hoist, preventing it from exceeding the predetermined area and causing excessive tension or damage to the steel wire rope.

6. Compliance with standards and certification

Compliance with standards: The fixing device of the electric hoist and its steel wire rope should comply with relevant national and international standards.

Certification requirements: The product should pass corresponding safety and quality certifications, such as CE certification, ISO9001, etc., to ensure its quality and safety.
