The RUBY Eye Grab Hook is a Grade 80 chain sling component designed to shorten a chain leg or hold a selected chain length during lifting operations. Its narrow throat engages between chain links, while the eye provides a connection point within a compatible chain sling assembly.

Product Features
High Load Resistance: Quenched and tempered Grade 80 alloy steel provides the mechanical strength required for rated lifting loads.
Secure Chain Engagement: The narrow throat and integrated supporting lugs help position and support the engaged chain link, reducing the risk of link deformation under rated use.
Corrosion Protection: The painted finish helps protect the hook surface during storage, handling and normal use.
Rated Capacity
Nine chain-size options: The range covers 6–32 mm chain sizes, with WLL values from 1.12 to 31.5 tonnes, supporting selection across different rated lifting requirements.
Defined breaking-load ratio: The listed MBL is four times the WLL for each model, corresponding to a 4:1 safety factor. This ratio does not replace the requirement to operate within the rated WLL.
Assembly Compatibility
Match the chain diameter first: Select the hook model corresponding to the chain size and verify that the chain grade and link geometry are compatible with the hook.
Check the complete assembly rating: The WLL of the finished chain sling is governed by its applicable design, configuration and component ratings-not by the hook rating alone.
Confirm the shortening arrangement: Use the hook only in the approved engagement configuration. Do not assume that every chain link or alternative rigging arrangement is acceptable.
Applications
Steel Structure Installation: Adjust chain sling lengths when lifting steel beams, columns and fabricated frames at different lifting points.
Machinery & Equipment Installation: Shorten individual chain legs to accommodate lifting points on industrial machines, presses and heavy equipment.
Mold & Die Handling: Adjust sling leg lengths when lifting injection molds, stamping dies and other heavy tooling with multiple lifting points.
Industrial Maintenance: Reconfigure compatible chain slings for removing, positioning or reinstalling heavy components during equipment servicing.
Proof Load and Fatigue Testing
Proof tested at 2.5 × WLL: The specified proof-test load provides a documented basis for checking the product's response to the required test load.
Fatigue tested at 1.5 × WLL for 20,000 cycles: RUBY specifies fatigue testing at the stated load for each batch.
Inspection documentation: Request the applicable test records and product identification details when documentation is required for incoming inspection or project approval.
Supply & Packaging
MOQ: 1 piece for sample orders; bulk orders accepted.
Lead Time: 30 working days for standard production orders.
Packaging: Export cartons with steel or wooden pallets for bulk shipments.
Supply Capacity: Up to 150,000 pieces per year, subject to model mix and order volume.
FAQ
Q: What Is the Difference Between an Eye Grab Hook and a Clevis Grab Hook?
A: An Eye Grab Hook uses an eye connection, while a Clevis Grab Hook has a clevis connection for direct attachment to compatible chain links. The choice depends on the connection method required by the chain sling assembly.
Q: Can an Eye Grab Hook Be Used as a Standard Lifting Hook?
A: No. An Eye Grab Hook is designed for its specified chain engagement and shortening function. It should not be substituted for a standard lifting hook unless the manufacturer explicitly approves that application.
Q: Can an Eye Grab Hook Be Welded Onto a Lifting Structure?
A: No. Do not weld the hook or modify its body unless the manufacturer provides an approved procedure. Unauthorized welding can alter the heat-treated steel properties and compromise lifting integrity.
Q: How Can Buyers Identify the Correct Eye Grab Hook Model?
A: Check the manufacturer's model code and permanent product markings against the product catalogue. For repeat orders, retain the original part number and approved specification to maintain consistency across replacement purchases.
Q: Can Eye Grab Hooks Be Supplied Under a Distributor's Private Label?
A: Private-label supply may be possible when the manufacturer supports customized product marking and packaging. Confirm logo placement, label content, minimum order quantity and artwork approval before production.
Q: When Should an Eye Grab Hook Be Removed From Service?
A: Remove the hook from service if inspection reveals cracks, deformation, severe wear, damaged supporting lugs or illegible safety markings. Have it assessed by a competent person before returning it to service.
