How many types of slings

Along with resistance to abrasion and high temperatures, nearly degree Fahrenheit, these slings are better suited for heavier loads and rugged facilities like construction sites. However, because of their heavier weight, they are harder to use than web slings and can cause minor injuries. Wire rope slings are also prone to damage from kinking, abrasion, and crushing. As a result, they need to be inspected regularly for any damages.

Advantages of web sling : Medium weight, economic, high temperatures, abrasion, and UV resistant. Disadvantages of web sling : Inflexible, can cause minor injuries, prone to damage. Among the three types of slings, chain slings are the most suited for industrial applications and heavy load lifting.

As a result, chain slings are extensively used in steel production plants and environments operating at high temperatures up to degree Fahrenheit.

Chain slings are designed for continuous use, all thanks to their durable strength and long life. They are also more suited to be used in facilities with harsh conditions like foundries and heavy machine factories.

Built through an advanced manufacturing process, KITO chain slings can be used for a variety of industrial lifting applications. What benefits do Grade chain slings have over Grade 80 chain slings? Several benefits, including the following:. Higher price to performance ratio. The work rated load of the attachments and components of the sling. Other physical characteristics of the load geometry, sharp edges, surface temperature, etc.

The environmental conditions temperature, humidity, presence of corrosive agents. The characteristics of different types of slings. Please see the individual documents as listed above: wire rope, fibre rope, chain, synthetic, metal mesh for information about: How to care for the sling.

How to inspect the sling. How to store the sling. When to remove a sling from use. Improper use of hoisting equipment, including slings, may result in overloading, excessive speed e. Factors to consider when choosing the best sling for the job include size, weight, shape, temperature, and sensitivity of the material being moved, and the environmental conditions under which the sling will be used.

The following guide may be useful in selecting the appropriate sling:. Chains Alloy steel chains are strong and able to adapt to the shape of the load. Care should be taken when using chain slings because sudden shocks will damage them.

This may result in sling failure and possible injury to workers or damage to the load. Chain slings must be visually inspected prior to use. During the inspection, pay particular attention to any stretching, nicks, gouges, and wear in excess of the allowances made by the manufacturer. These signs indicate that the sling may be unsafe and must be removed from service immediately. Wire Rope Wire rope is composed of individual wires that have been twisted to form strands.

Strands are then twisted to form a wire rope. When wire rope has a fiber core, it is usually more flexible but less resistant to environmental damage. Conversely, wire rope with a core that is made of a wire rope strand tends to have greater strength and is more resistant to heat damage.

Wire rope slings must be visually inspected before use. Slings with excessive broken wires, severe corrosion, localized wear, damage to end-fittings e. Fiber Rope and Synthetic Web Fiber rope and synthetic web slings are used primarily for temporary work, such as construction or painting, and are the best choice for use on expensive loads, highly finished or fragile parts, and delicate equipment. Fiber rope slings deteriorate on contact with acids and caustics and, therefore, must not be used around these substances.

Fiber rope slings that exhibit cuts, gouges, worn surface areas, brittle or discolored fibers, melting, or charring must be discarded. A buildup of powder-like sawdust on the inside of a fiber rope indicates excessive internal wear and that the sling is unsafe. Finally, if the rope fibers separate easily when scratched with a fingernail, it indicates that the sling has suffered some kind of chemical damage and should be discarded.

Synthetic web slings are commonly made of nylon, polypropylene, or polyester and have the following properties in common:. Slings, chokers, shackles and hoists are are available in many different materials and styles. Slings are commonly used in combination with a lifting device, such as an overhead crane, hoist, or forklift. The four main types of slings are:. Wire Rope: The most commonly used sling. Used in the construction and other applications where heavy loads and rugged conditions exist.

Chain: Combines superior strength, ease of handling and durability. The combination of heavy loads, elevated working temperatures and severe lift conditions usually dictate that an alloy chain sling be used.
