William Hackett Hack8 Grade 8 Four leg Chain Sling Assembly – 2m Standard Reach (3.1t to 67t WLL)

Description

Hack8 Four Leg Chain Sling

The Hack8 Grade 8 Four Leg Chain Sling Assembly is a premium heavy-duty lifting and rigging solution engineered to provide maximum load stability, enhanced lifting control, and high-capacity performance in demanding industrial environments. Designed, manufactured, tested, and certified in the United Kingdom by William Hackett, this professional multi-leg chain sling is ideal for complex lifting applications where safety, precision, and compliance are essential.

Four leg chain slings are widely used for lifting large structural loads, heavy machinery, modular fabrications, precast concrete units, steel assemblies, and oversized industrial components. The four-leg configuration distributes the load across multiple lifting points, significantly improving balance, minimising load movement, and enhancing positioning accuracy during lifting operations.

Designed for professional lifting operations across construction, offshore, manufacturing, engineering, marine, and heavy industrial sectors, each Hack8 sling assembly is custom manufactured to order for complete compatibility with cranes, gantries, lifting beams, spreader frames, and specialist rigging systems.

Bespoke Four Leg Chain Sling Assemblies for Heavy Lifting

Every Hack8 four leg chain sling is individually manufactured to suit the exact lifting requirements of the application. This bespoke approach allows operators and lifting engineers to configure the sling for optimal performance and safe load handling.

Available customisation options include:

• Chain diameters from 7mm to 32mm
• Working Load Limits from 3.1t to 67t
• Bespoke sling lengths
• Master links and sub-assemblies
• Shortening clutches and grab hooks
• Self-locking safety hooks
• Foundry hooks and lifting shackles
• Specialist end fittings on request

This flexibility ensures seamless integration with a wide range of lifting equipment and rigging hardware across complex lifting environments.

Maximum Stability for Complex Multi-Point Lifting

The four-leg sling configuration delivers exceptional load stability and control when lifting large, awkward, or irregular loads requiring multiple attachment points.

Key operational advantages include:

• Superior load balance during lifting operations
• Reduced load swing and movement
• Improved control when positioning heavy components
• Enhanced safety for wide or uneven loads
• Increased lifting stability during transport and installation

These benefits make the Hack8 four leg chain sling particularly suitable for precast concrete installation, modular construction, offshore fabrication, heavy engineering, shipbuilding, and industrial plant lifting operations.

Premium Grade 8 Alloy Steel Construction

Manufactured from high-strength Grade 8 alloy steel chain and fittings, the Hack8 sling assembly is engineered for repeated heavy lifting cycles and harsh industrial conditions.

Chain and components are manufactured in accordance with:

• EN818-2
• EN1677-1
• ASTM A391/A391M
• EN818-4 chain sling assembly standards

The Grade 8 alloy steel construction provides:

• Excellent tensile strength
• High fatigue resistance
• Enhanced durability under dynamic loading
• Long operational service life
• Reliable performance in demanding environments

This robust design ensures dependable lifting performance across industrial, offshore, and infrastructure applications.

RFID Traceability & Digital Inspection Management

Every Hack8 chain sling assembly is fitted with an integrated RFID identification tag to support modern lifting equipment management and compliance procedures.

Using the William Hackett App, users can instantly access:

• Product specifications
• Test certification documents
• Inspection records
• User instructions
• Safety and compliance information

This RFID-enabled system improves asset traceability, simplifies LOLER inspection routines, and supports efficient equipment management across industrial lifting fleets.

Proof Tested & Certified for Critical Lifting Operations

All Hack8 four leg chain sling assemblies are proof load tested to 2.5 times their Working Load Limit and manufactured with a minimum 4:1 safety factor.

Working Load Limits range from 3.1 tonnes up to 67 tonnes at lifting angles between 0° and 45°. Reduced capacities apply at wider lifting angles between 45° and 60° to maintain safe and compliant lifting performance.

The sling maintains full rated lifting capacity within an operational temperature range of:

• –40°C to +200°C

This makes the Hack8 four leg chain sling suitable for offshore projects, marine environments, heavy construction, steel fabrication, and high-temperature industrial processes.

Each sling assembly is fully certified and supplied with conformity documentation to support safe and compliant lifting operations.
