This article discusses everything you need to know about wire rope slings. It includes different types of wire rope slings and sling accessories. The article also discusses commonly used wire rope slings for various applications.
Wire Rope Sling Parts And Components
There are many types of wire rope slings, among which the most common types are the following three kinds, they all consist of certain components. The other wire rope slings are composed of almost only the rope core ( fiber core/steel core). This section will discuss the different wire rope sling parts.
- Spliced Wire Rope Sling
Spliced wire rope sling is made by pressing and machining of wire rope press sleeve machine. It uses the sleeve to press one or both ends of the wire rope into a circular shape. Some wire rope slings with thimbles, some without. So, spliced wire rope sling consists of rope core, sleeve, and thimble.
- ROPE CORE
The main function of the wire rope core is to support the wire rope, in order to achieve a stable cross-sectional structure, increase the flexibility and toughness of the wire rope, lubricate the wire, reduce friction, and improve the service life of the wire rope.
Common types of rope core are fiber core (such as hemp, cotton) and steel core. Fiber core including natural fiber core and synthetic fiber core, natural fiber core such as sisal, jute, cotton thread, etc., synthetic fiber core including polyethylene and polypropylene filament, etc.. It is mainly to lubricate the effect of corrosion to delay the wire rope.
The steel core wire rope is more wear-resistant than the fiber core wire rope, anti-extrusion, with higher service life, break tension is also relatively high, and the softness is slightly lower. Because of wear-resistant and pressure-resistant , steel core wire rope is generally applied to the crane. It can be used in the working environment of high temperature places, and can withstand the extrusion of external force transverse to the steel wire rope.
- SLEEVE
Spliced wire rope sling would use sleeving swaging process, which is of stable quality, high production capacity, and reliability, as well as mass production.
In Sichwirerope manufacturer, there are a wide variety of sleeves for wire rope slings, for example, flemish eye steel swaging sleeves(S 505), aluminum ferrules(DIN 3093), round sleeves, oval sleeves, hourglass sleeves, stop buttons, etc.
- THIMBLE
The function of the wire rope thimble is to connect other components and tie around the end of the rope to prevent excessive bending and abrasion. It is an important part of the wire rope sling.
1) the thimble should be smooth and flat, there should not be any damage to the wire rope cracks, defects, sharp edges and surface roughness, and inequality defects. The tip of the thimble should be free to fit the wire rope, and the tip part should be cut short to half of the groove depth.
2) the surface of the thimble should be hot dipped galvanized, and it should be smooth and flat, there should be no defects such as leakage, zinc particles, bubbles, and cracks, and the galvanized layer should have sufficient adhesion strength in normal application.
3) the material of the thimble can be stainless steel or high-quality carbon steel.
4) the thimble safety load should be at least 32% of the wire rope breaking the tension.
5) the thimble should be used to meet the specifications of the wire rope, the diameter of the pin shall not be less than two times the diameter of the wire rope.
- Wire Rope Bridle Sling
Spliced wire rope sling is made into single-leg, 2-leg, 3-leg, 4-leg, or multi-leg wire rope slings, known as Wire Rope Bridle Sling. At one end of the swaged wire rope sling is the link and at the other end is the end fitting. So, wire rope bridle sling consists of spliced wire rope sling, link, and end fitting.
- LINK
The link is the connector between the hoist and the lifting object, which is widely used and is a common rigging accessory. It can be used alone or in combination with another rigging, and it is safe, reliable, and long-lasting.
The link is used for lifting goods, mainly as a connector, so that the cargo can be carried, at the same time it can reduce the workforce, which can greatly enhance the efficiency of labor.
The link can be used not only alone, but also with other lifting equipment, it is small in size, light weight, user-friendly, high safety in use, high strength, and not easy to break.
In our Sichwirerope Manufacturer, we supply various types of links and rings, such as master links, master link assembly, pear links, and weldless rings with ASTM and Federal standards.
- END FITTING
Multi-legged wire rope sling with one end as the connector and the other end as the end fitting. When lifting heavy objects, different end fittings are required depending on the weight of the object, such as hooks, shackles, and so on.
In shackles, for example, the wire rope is located in the force part, and the pin is at the fixed end so that no rotation will occur in the hoisting process, and the tightness of the shackle connection is well ensured.
- Socket Sling
Socket wire rope sling is made from the world’s high-quality wire rope and high-strength anchors. It is integrated with the world’s advanced casting process. It is a specialized tool for holding, transferring, and handling heavy objects. It is also a key part of the prerequisite, the pressure of the metal structure. It is available in two forms hot and cold casting, and its structure is divided into open, closed, forked, adjustable, etc. So, the socket sling consists of wire rope, and socket.
- SOCKET
In our Sichwirerope Manufacturer, there are open socket slings and closed socket slings, and both of them have the following features:
- available for wire rope from 6mm to 102mm in diameter.
- reach the rated tension of the wire rope better.
- 6-38mm sockets are forged alloy steel, and 40mm or more large-size are available in cast alloy steel and forged alloy steel.
- made of hot-dip galvanized.

- Ports & Container Terminals Industry
- Petroleum Chemical Projects Industry
- Power Plant projects Industry
- Infrastructure Construction Industry
- Offshore Oil & Gas Industry
In coastal areas, there are plenty of drilling platforms and oil extraction platforms where wire rope sling is widely used as an important tool. As the offshore environment is harsh, with severe salinity and humidity, so high resilience and thick galvanized steel wire ropes are necessary.
In the offshore oil & gas industry, steel core 6×19S, 6×19W, 6×25F, 6×26WS, 6×29F, 6×31WS, 6×36WS wire rope is recommended.
- Salvage Operations Industry
Salvage operations are the project to salvage sunken objects in the water. Including salvage of ships, aircraft, cargo, etc. Salvage operations in the waterway, and harbor areas, can clear the navigable obstacles.
Galvanized 6×36WS, 6×41WS, 6×49SWS, 6×31WS, 6×55WS, 8×19W, 8×31WS, 8×36WS, 8×41WS, 8×49SWS, 8×55SWS wire rope is recommended for salvage operations industry.
- Mariculture Industry
The Mariculture industry includes crab farming, shrimp farming, etc., which generally uses galvanized steel strand wire rope. The hot-dip galvanized steel strand wire rope is oil-free and has the ability to prevent corrosion.
Usually, 6×36WS, 6×31WS, 6×26WS, 6×19(S), 6×24, 6×7 wire rope is recommended.
- Marine Industry
Due to the erosion of seawater, ship wire rope is exposed to seawater, salt, and sun screen every day, and it is used with anti-corrosion material, which is generally used for reinforcement, and must be replaced at 5% of the time considering the strength of resistance to typhoons, so we recommend:
- Galvanized 6×19W, 6×25F, 6×29F, 6×31WS, 6×36WS which is wire contact wire rope.
- 18×19S, 18×19W, 34×7, 36×7, 35W×7, 24W×7 is multi-layer strand wire rope.
- 4×V39S, 4×V48S is a four-strand fan strand wire rope.
- Ports & Container Terminals Industry
Port lifting and handling wire rope, in the current market, the structure is mostly 6 or 8 strands, common 6 strands of wire rope are 6*36WS+IWR, 6*29Fi+IWR, tensile strength grade 1770MPa, 1670MPa.
Our suggestion is that gradually choose 8 strands of wire rope, such as 8*31WS+IWR, or 8*36WS+IWR. 8 strands are softer than the traditional 6 strands of wire rope, and because it is a steel core, can be better impact resistance, and frequency resistance.
- Petroleum Chemical Projects Industry
Wire rope is an indispensable part of the petroleum industry. Steel wire rope is generally twisted and made of high-carbon steel wire. There are multiple specifications of steel wire rope, for the chemical industry, and lifting projects commonly used: 6×19+1, 6×37+1, and 6×61+1 three types.
Among them, 6 means the number of strands wound into wire rope, 19 (37, 61) means the number of wires in each strand, and 1 means the middle of the fiber core.
- Power Plant projects Industry
Port lifting and handling wire rope, in the current market, the structure is mostly 6 or 8 strands, common 6 strands of wire rope are 6*36WS+IWR, 6*29Fi+IWR, tensile strength grade 1770MPa, 1670MPa.
Our suggestion is that gradually choose 8 strands of wire rope, such as 8*31WS+IWR, or 8*36WS+IWR. 8 strands are softer than the traditional 6 strands of wire rope, and because it is a steel core, can be better impact resistance, and frequency resistance.
- Infrastructure Construction Industry
The use of wire rope in construction projects is increasing, such as tower cranes, elevators for people and goods, derrick lifts, baskets, and so on. In general, the selection of steel wire rope can consider the following：
- 6×19 steel wire rope is used for cable wind rope, pulling the rope, and making lifting rigging, which is generally used in places where the bending load is small or suffering from wear and tear.
- 6×37 steel wire rope used for lifting operations in the lashing of various objects, equipment, and threading around the pulley set and the production of lifting rigging.

Wire Rope Sling Cores
The core is the inner part of the wire rope, and there are two types of wire rope cores: fiber core, and steel core. This section will list the differences between each type.
What is the main function of the wire rope core?
- support the rope strand to keep a certain cross-sectional shape, reduce the contact stress and extrusion deformation between the wires
- increase the flexibility of the wire rope, and elastic cushion role, when the wire rope bending, the wire strand or between the wire can move relatively, in order to ease the bending stress
- store lubricating oil, prevent the rope wire rust and reduce the friction between the wires
- Fiber Core (FC)
Fiber core wire rope is composed of a fiber rope in the middle, with the letter FC said. It includes natural fiber core and synthetic fiber core,
- Natural fiber core: sisal, jute, cotton thread, etc.,
- Synthetic fiber core: polyethylene and polypropylene filament, etc.
Natural fiber core could store more grease, lubricate the wire rope, prolong the service life of wire rope.
- Steel Core (IWS/IWR)
Steel core wire rope is composed of one rope strand or steel wire in the middle. With the letter IWS or IWR said.
- Steel wire: the basic strength unit of wire rope, requires high strength and toughness.
- Rope strand: twisted by the steel wire into each small rope strand. The same diameter and structure as the wire rope, the number of strands is high fatigue strength.
- Differences
- The difference in material
Fiber core wire rope is composed of a fiber rope in the middle, with the letter FC said. Its material is basically the same as the fiber used in general fiber rope, and the steel core wire rope is composed of a stainless steel wire rope in the middle, with the letter IWS or IWR said. The steel core wire rope of the same diameter is larger than the breaking tension of the hemp core wire rope, and the load borne is also large.
- The difference in quality
The steel core wire rope is more wear-resistant and anti-extrusion than the fiber core stainless steel wire rope, with higher service life, and relatively high breaking tension, the softness is relatively low. Because of the resistance to wear and pressure, steel core wire rope is generally used in cranes or winches. The steel core wire rope in high-temperature resistance is higher than the fiber core wire rope.
- The difference in price
The price of steel core wire rope is relatively higher than fiber core steel core wire rope, but considering the service life and the tension, steel core wire rope will be relatively good. So in general, the cost of steel core wire rope is lower.
Wire Rope Sling Thimbles
Wire rope thimbles with rope groove, for the end of the rope around the tie, to prevent excessive bending and wear of the rope and cable and can be connected to other components of the heart-shaped metal ring.
In our SichWirerope rigging hardware manufacturer, there are 3 types of wire rope thimbles:

Wire Rope Sling Sleeves
Wire rope sling sleeves are used to secure the ends of wire rope slings for added safety and strength. They are available in a wide variety of materials and sizes, depending on the type of wire rope sling and the application.
There are two main types of wire rope sling sleeves in our SichWirerope rigging hardware manufacturer:
- Mechanical sleeves: have an eyelet that is crimped shut and secured with a set screw
- Swaged sleeves: typically welded together and are stronger than mechanical sleeves.
To work, the sleeve is first attached to the wire rope sling. Once securely fitted, the eyelet is crimped or swaged shut using a hydraulic tool. The set screw is then tightened to secure the sleeve in place. After the sleeve is secured, the eyelet is then connected to a hook or shackle.
Wire rope sling sleeves are commonly used in a variety of applications including lifting, rigging, hoisting, and marine. They are an essential component for ensuring a safe and secure connection between the sling and the load. Additionally, they are used to extend the life of the wire rope sling, as they protect it from abrasion, wear, and fatigue.

Wire Rope Sling Capacity Formula
Commonly, we will provide Wire Rope Sling Capacity Chart for you
Wire rope sling capacity formula = (Diameter of rope squared) x Length of rope x Safe Working Load (in lbs) / 8.
*Example:
A wire rope with a diameter of 1/2 inch and a length of 8 feet has a safe working load of 1200 lbs.
Wire rope sling capacity = (0.5^2) x 8 x 1200 / 8
Wire rope sling capacity = 300 lbs.
And if you need to calculate the bridle wire rope sling, the capacity of a wire rope sling is determined by multiplying the vertical capacity by the horizontal capacity. The vertical capacity is determined by multiplying the diameter of the rope by the strength of the rope, then multiplying this product by the number of legs of the sling. The horizontal capacity is determined by dividing the total capacity by the number of legs of the sling.
*Example:
If the rope is 7/16″ in diameter and has a strength of 8,400 lbs. and the sling has two legs,
the vertical capacity of the sling is:
7/16″ x 8,400 lbs. x 2 legs = 66,400 lbs.
The horizontal capacity of the sling is:
66,400 lbs. ÷ 2 legs = 33,200 lbs.
