1, Define the lifting requirements
Information of the object to be lifted: including weight, size, shape, center of gravity position, material (whether it is fragile or not) and so on.
Lifting environment: consider space limitation, ground condition, weather and other factors.
Lifting method: Determine whether to lift horizontally or vertically, and whether it needs to be turned over.
2, Selecting the appropriate type of sling
Choose the appropriate type of sling according to the demand:
Wire rope: high strength, wear-resistant, suitable for many occasions.
Chain: strong carrying capacity, high temperature resistant.
Sling: lightweight, soft, not easy to damage the surface of objects, but lower strength.
Specialized slings: such as hooks and beams, suitable for specific scenarios.
3, Pay attention to the performance parameters of the sling
Rated load: must be greater than the weight of the suspended object, and consider the effect of dynamic load.
Length: choose according to the lifting height and the size of the object be lifted.
End fittings: such as hooks, buckles, etc., should be ,atched with the sling and meet the strength requirements.
4, Inspection and Maintenance
Pre-use inspection: make sure the sling is free from damage, deformation, rust and corrosion.
Regular maintenance: clean, lubricate and store properly to prolong the service life.
End-of-life sandard: slings that reach the end-of-life standard should be replaced in time.
5, Safe operation
Licensed to work: operators need to go through professional training.
Standardized operation: comply with the safety regulations and eliminate illegal operation.
Signal communication: Ensure that the command signal is clear and unambiguous.
Alert area: set up a warning line and prohibit unrelated personnel from entering.
6, Other suggestions
Consult the professionals: When you are not sure, seek professional advice.
Choose reliable brands: Ensure product quality and after-sales service.
Record archives: Keep records of sling inspection, maintenance and scrapping.
Through the above techniques, reasonable selection and use of slings can effectively improve lifting efficiency and safety.
