The correct use of the most commonly used slings among lifting equipment is extremely important. Not only cranes but also slings are of great importance in lifting and transporting loads. A sling consists of steel ropes, chains, webbing and fibre ropes. Since slings that are not used according to the rules of application may pose a risk, sling binding forms are of great importance. According to the usage of the slings, the lashing forms and load-carrying capacities vary depending on these forms. Fastening types of slings include vertical binding, strangulation binding, U-lift and embrace binding.
What are Sling Fastening Types?
The lashing types applied in the use of slings are very important for safe use. The sling-lashing types are as follows:
- Vertical Binding
It is the vertical lifting of a load to be lifted or transported using a single sling. In this sling attachment method, loads that do not exceed the safe working capacity of the slings can be lifted. However, the rotation of the load being lifted or transported during the operation may result in the sling bending. In this case, damage to the slings may occur. It is necessary to pay more attention to this issue when using vertical lashing.
- Choke Binding
The carrying capacity of the sling to be used in the strangling process should be calculated according to the angles of use. Slings that meet this capacity should be utilised. In the form of strangle lashing, the sling lashing capacities must be calculated for the loads to be transported or lifted. The angle formed in this type of lashing must be above 120 degrees. Calculations below 120 degrees require you to be more careful.
- U Lifting and Embracing Lashing
In U-shaped lifting operations, the load lifted or carried is evenly distributed over the two arms of the sling. However, the lifting angles of the arms reduce the sling capacity in direct proportion to the size of the resulting angle.
What should be considered when connecting to the sling?
The points to be considered during sling attachment help to get the most accurate results.
- The sling arm must not be caught in the sewn overlaps of loaded hooks or other lifting devices and must not be caught in the seams of the sling arm.
- The contact area of slings in the form of bands must be flat. In this way, the entire cross-section of the sling is loaded evenly.
- Round slings should not be entangled in the crane hook. The mouth of the hook must have the necessary space for the loads. Thus, it takes its natural flat profile and a balanced loading can be achieved across the full width of the round sling.
- Flat band slings should be applied in such a way that they can carry the load of the sling width. Wide and vertical angles may cause the edges of the slings to stretch and break.
