Rigging Hardwares: Types and Selection Guide for Industrial Lifting

Rigging hardware connects a lifting machine, sling, and load, helping transfer forces through a planned lifting system. Common types include shackles, eye bolts, hooks, master links, swivels, and turnbuckles. To select suitable hardware, match each component’s working load limit (WLL), material, connection geometry, and operating conditions to the lift—not just to the load’s weight. At Lihua, we recommend confirming the full lifting arrangement and product documentation before ordering or use.

Who This Guide Is For

This guide is for industrial buyers, maintenance teams, engineers, and project planners sourcing rigging hardware for lifting and load-securement applications. It is useful when comparing product types, preparing a specification, or requesting a quotation from a supplier. It is not a substitute for a lift plan, competent-person assessment, or the requirements that apply in your location.

Rigging Hardware Basics

Rigging hardware is a group of load-bearing components used to connect, adjust, or terminate parts of a lifting system. A typical arrangement may include a crane hook, master link, sling legs, and shackles connecting those legs to the load. Each component has its own rated capacity and limitations, so a system is only suitable when every part is appropriate for its position and loading.

The WLL is the maximum load assigned to a product under its specified conditions. It should not be confused with breaking strength, which is not an allowable working load. Buyers should check the product marking and supporting documents, and should not estimate capacity from appearance, material thickness, or a similar-looking item.

Common Types and Materials

Shackles

Shackles provide removable connections between slings, lifting points, and other hardware. Bow shackles offer a wider body shape that can accommodate connections from more than one direction when the manufacturer permits that arrangement, while dee shackles are generally used for more in-line connections. Pin type, body shape, dimensions, WLL, and loading direction all matter; side loading can change the allowable capacity.

Eye Bolts and Lifting Points

Eye bolts and other lifting points attach hardware to a machine, structure, or load. Selection depends on the mounting thread or interface, base material, engagement, direction of pull, and whether the point is intended for angular loading. A lifting point should be installed as specified by its manufacturer, and the supporting structure must also be suitable for the intended load.

Hooks, Master Links, and Swivels

Hooks connect a lifting system to a load or another component, while master links gather sling legs at a central connection. Swivels can allow rotation in certain applications, but not every swivel is designed to rotate under load. Buyers should confirm the intended function, orientation, locking or retention features, and permitted loading conditions for each product.

Turnbuckles and Material Options

Turnbuckles adjust tension or length in suitable assemblies, but a standard adjustment fitting should not automatically be treated as lifting hardware. Verify that the selected product is specifically rated and approved for the intended use. Rigging hardware is commonly available in steel grades and finishes suited to different environments; stainless steel may be considered where corrosion resistance is important, but material choice alone does not establish a product’s capacity or suitability.

Match Hardware to the Application

Start with the lifting task: identify the load, its center of gravity, designated lifting points, and the planned sling arrangement. Then consider the operating environment, including moisture, corrosive exposure, temperature, abrasion, and the frequency of use. These factors can affect the choice of material, finish, inspection approach, and product configuration.

Connection geometry is equally important. Check pin diameter and fit, thread compatibility, available clearance, sling angle, and whether components will be loaded in line or at an angle. A component that fits physically may still be unsuitable if its loading direction or contact surface is outside the manufacturer’s stated limits.

A Practical Selection Framework

1. Establish the Load and Lift Configuration

Record the load mass, how it will be supported, and the number and position of sling legs. Do not assume that multiple legs share the load evenly: center-of-gravity position, leg length, and rigging geometry can create unequal loading. Include relevant lift-plan considerations such as acceleration, shock loading, and any restrictions stated for the equipment.

2. Account for Sling Angle

As sling legs become more horizontal, the tension in each leg increases. For a simplified, symmetrical two-leg arrangement carrying a 2,000 kg load evenly, with each leg at 60° above horizontal, the calculated tension is about 11.3 kN per leg. At 30° above horizontal, it is about 19.6 kN per leg; these are idealized calculations, not product ratings or a complete lift assessment.

The calculation assumes equal load sharing and a static load, so actual conditions can differ. Use the applicable sling-angle factors, manufacturer information, and a competent lifting professional to establish the required capacity. Never select hardware by dividing the load by the number of components without checking the full geometry and loading conditions.

3. Verify Ratings, Interfaces, and Documentation

Compare the required capacity with the WLL for every component in its actual configuration. Confirm dimensions, connection compatibility, material, finish, product identification, and any restrictions on side loading or angular loading. Request product documentation that identifies the item and its ratings, and check which standards or regulatory requirements apply to your product and market.

Pricing, MOQ, and Lead Time

Rigging hardware pricing depends on product type, size, material, finish, rating, quantity, and documentation or packaging requirements. Minimum order quantities and lead times can vary by specification, stock position, production schedule, and destination. Rather than relying on a generic estimate, buyers should send a clear item list and ask suppliers to confirm current availability, MOQ, delivery terms, and any charges that apply.

For a comparable quotation, provide drawings or part references where available, required quantities, destination, and the intended application. Identify whether you need standard items or a particular configuration, and state any inspection, marking, or documentation requirements. This helps suppliers assess the request without making assumptions about a product’s suitability.

Supplier Evaluation Checklist

• Can the supplier identify the product type, dimensions, material, finish, and WLL clearly?
• Can they provide relevant product identification and documentation for the requested item?
• Do they ask about the application, connection geometry, and operating environment?
• Are MOQ, lead time, packaging, delivery terms, and quotation validity stated clearly?
• Can they explain which specifications require confirmation before an order is finalized?

Evaluate the supplier on the clarity and completeness of its response, not on a broad claim of suitability. A responsible sourcing discussion should distinguish confirmed product details from items that still require engineering or application review. If the request involves an unusual lift, non-standard configuration, or uncertain loading, resolve those points before placing an order.

Key Takeaways and Next Steps

Rigging hardware includes connection, adjustment, and lifting-point components, and each type has different uses and limitations. The right selection depends on WLL, load geometry, sling angle, component compatibility, material, environment, and applicable requirements. A product’s appearance or nominal capacity alone is not enough to confirm that it is suitable for a complete lifting arrangement.

To move forward, prepare the load details, lifting configuration, required product types and quantities, operating conditions, and documentation needs. Share this information with Lihua so our team can review the requested specification and confirm product options, MOQ, and lead time. Final selection and use should be checked against the lift plan, product instructions, and applicable local requirements.
