Explained: Different Types of Wire Rope Sling Hitches

                    Wire rope slings serve a pivotal role in lifting and hoisting operations across several industries. Selection of wire sling remains critical to ensure a safe and risk-free environment. This selection depends on several key factors derived from the nature of the load being carried. In this article, we will go through the different types of lifting slings configurations that are used to ensure better load control and safe working conditions.

The configuration of lifting a load is called a hitch. Lifting slings are designed to carry loads in one of three primary hitches explained below:

Vertical Hitch:

Vertical or Straight hitch, defines the construction wherein one eye of the sling is attached to the lifting device, while the other eye is connected to the load being carried. This construction induces the entire rating of lifting capacity. One must ensure the use of a tagline to aid load control, and mitigate twisting motion while performing a lift.

 

 

Choker Hitch: The type of arrangement in which the eye of the sling is drawn though the other eye to create a chokepoint is called a choker hitch. This arrangement considerably reduces the lifting capacity of the sling as it directly hampers the wire rope ability to adjust while placed under angular loading. A choker must be employed in a scenario where the sling body doesn’t jeopardize the carrying load.

 

Basket Hitch: This arrangement is formed when both eyes of a sling are attached to a single overhead lifting unit. This equally distributes the load across two ends of the sling where the load is cradled in a basket form. Operators must prohibit the use of basket hitch for applications requiring lifting of an unbalanced load.

 

Lifting Bridles: This special type of rigging method involves the process of attaching two or more slings to a single lifting hook. These assemblies come with adjustable sling length which accommodates unbalanced loads by keeping the center of gravity align. Operators must ensure the sling angle is kept within working limits to prevent overloading the slings beyond rated capacities.

 

Note: A trained and certified operator is must to ensure appropriate lifting practices. Please refer operation, and safety manuals while carrying out the processes.
