Yoke Hooks

About Yoke Hooks

Holloway Houston stocks Yoke hooks in clevis and shank configurations, with safety latches where the application calls for them. WLL range from 1 ton through 32 tons covers chain sizes from 7/32 inch through 5/8 inch.

Yoke chain sling hooks terminate the legs of Grade 80 and Grade 100 chain sling assemblies. They are forged from alloy steel, heat-treated to match the grade of chain they attach to, and proof-tested before shipping. Every hook is marked with the working load limit and manufacturer identification per ASME B30.10.

ASME B30.10 (Hooks) governs the design, marking, inspection, and use of hooks in load-handling service. A hook's working load limit is stamped in a low-stress, non-wearing area so the rating stays legible through normal service life.

Yoke hooks are available with safety latches as a standard configuration. The latch keeps the load in the hook bowl and prevents accidental disengagement during the lift.

Types of Yoke Hooks

Clevis Hooks (Grade 80)

Clevis hooks have a U-shaped clevis jaw with a pin, allowing direct connection to chain links without an intermediate fitting. Grade 80 clevis hooks match Grade 80 chain sling assemblies and are the standard specification for most industrial overhead lifting. WLL range covers 1 ton through 22 tons across chain sizes from 7/32 inch through 1/2 inch.

Clevis Hooks (Grade 100)

Grade 100 clevis hooks carry higher WLL ratings than Grade 80 at the same chain size. Where the chain sling assembly is built on Grade 100 chain, Grade 100 hooks are the matched termination. WLL range from 1.4 tons through 32 tons for chain sizes 7/32 inch through 5/8 inch.

Shank Hooks

Shank hooks for chain slings use a straight stem that inserts into a master link or coupling hardware rather than directly connecting to chain links. These are used as the top hook on single-leg sling assemblies and in specialized rigging setups where the shank provides a cleaner connection geometry.

Hooks with Safety Latches

All Yoke chain sling hook models are available with positive-locking safety latches. The latch opens only with deliberate manual action, keeping the chain seated in the hook bowl throughout the lift. Latched hooks are the standard specification where OSHA regulations or lift procedures call for latch retention.

Yoke Hook Sizes and Working Load Limits

Yoke hooks cover chain sizes from 7/32 inch through 5/8 inch.

Working Load Limit Range:

• Grade 80: 1 ton to 22 tons (7/32" through 1/2" chain)
• Grade 100: 1.4 tons to 32 tons (7/32" through 5/8" chain)

Material:

• Alloy steel.
• Quenched and tempered.

Marking per ASME B30.10:

• WLL.
• Grade.
• Manufacturer ID.
• Lot number.

Latch options:

• Safety latch standard.
• Open throat available for specific applications.

Why Yoke for Hooks

Yoke hooks are grade-matched to the chain lines they terminate, the WLL at each chain size is developed on the matched alloy grade, not a generic safety factor applied to carbon steel. For chain sling fabricators and maintenance crews replacing hook ends on existing assemblies, that grade consistency matters for maintaining the rated capacity of the sling.

ISO 9001 certification covers Yoke's forging, heat treatment, and proof test process. The proof test certificate that ships with every hook gives inspectors and safety managers the documentation they need without a separate request.

Holloway Houston also provides rigging inspection services. Our qualified inspectors examine chain sling hooks, sling assemblies, and hardware per ASME B30.10 and ASME B30.9 standards.

Yoke Hook Applications by Industry

• Jobsite rigging : Chain sling leg termination on multi-leg assemblies for structural steel and precast concrete picks.
• Oil and Gas : Turnaround maintenance and heat exchanger lifts where Grade 100 hooks extend WLL in space-constrained rigging setups.
• Heavy Manufacturing : Foundry and steel mill chain sling assemblies where hooks take repeated high-tonnage picks.
• Mining : Chain sling termination on heavy equipment and materials handling in abrasive conditions.
• Offshore : High-capacity Grade 100 hook terminations on crane sling assemblies on platforms and vessels.

Hook Safety and Awareness

ASME B30.10 (Hooks) governs the design, marking, inspection, maintenance, and use of hooks in load-handling applications. OSHA 1910.179(j) covers hooks on overhead cranes. OSHA 1926.251 covers rigging equipment for jobsite use.

Key awareness points:

• Per ASME B30.10, hooks are marked with WLL and manufacturer identification. A hook with illegible markings warrants removal from service.
• Pre-use visual inspection covers the hook body for cracks, the throat for deformation, and the latch for proper function. Twist beyond 10 degrees from the plane of the unbent hook is cause for removal per OSHA 1910.179(j).
• Grade matching between hook and chain is a sling assembly integrity issue. A Grade 80 hook on a Grade 100 chain limits the sling to the Grade 80 WLL at that connection.
• Welding or reshaping hooks is not recognized under ASME B30.10. Modifications void the WLL marking and may introduce failure points.
