William Hackett Lifting Products
Holloway Houston Inc. is proud to stock a comprehensive inventory of William Hackett’s HA OS+ Master Links, Quad Assemblies, and specialized Subsea Hoists. Whether you are rigging a wire rope container sling for an oil platform or requiring a lever hoist that performs underwater, William Hackett delivers the certified reliability required by DNV and ASME standards.
Product Spotlight: HA OS+ Master Links
The HA OS+ Series found in our inventory is specifically designed for the offshore energy sector.
- Zinc-Tough Technology : Unlike standard powder coating, the OS+ series features a dual-layer protection system. A zinc-rich primer provides cathodic protection (similar to galvanizing) followed by a durable orange powder topcoat. This offers exceptional resistance to salt spray corrosion.
- Charpy Impact Tested : These links are manufactured from Triple Alloy Steel and impact tested at -20°C (40 Joules) or -40°C (27 Joules), ensuring they remain tough and ductile even in freezing North Sea or Arctic conditions.
- Compliance : Fully compliant with DNV 2.7-1 for offshore containers.
Innovation: Master Links with Handles
Rigging heavy master links can be dangerous. A pinch point between the crane hook and the link can cost a rigger their fingers.
- The Solution : HHI stocks William Hackett Master Links with Integrated Handles (e.g., #330.360.H).
- The Benefit : These welded handles allow the rigger to guide the heavy link onto the crane hook safely, keeping hands completely clear of the crush zone.
Product Spotlight: Hoisting Technology
William Hackett hoists are engineered for environments where standard hoists fail.
1. SS-L5 QP Subsea Lever Hoist
- Application : Designed specifically for Subsea (Underwater) and splash-zone use.
- Corrosion Defense : Features a multi-process surface treatment that withstands 1,000+ hours of salt spray testing.
- Quad Pawl (QP) : Utilizes a patented Quad Pawl mechanism that ensures redundant engagement, maximizing safety during critical subsea lifts.
2. WH-L4 Lever Chain Hoist
- Application : The industrial workhorse for topside rigging.
- Design : Rugged steel construction with a compact design for tight spaces. Meets ASME B30.21 standards.
The "Quad" Advantage
For multi-leg slings, we stock HA Quad Assemblies.
- Configuration : Consists of a main Master Link joined with two Intermediate sub-links.
- Usage : The required termination for 3-Leg and 4-Leg wire rope or chain bridles.
- Capacity : Our inventory ranges from standard lifts to massive heavy-lift assemblies (e.g., HA50QA with 112,000 lbs WLL).
Technical Specifications & Traceability
- Safety Factor :* Master Links : 5:1 (Minimum).
- Hoists : 4:1.
- Proof Testing : 100% of links are proof load tested to 2.5 times the Working Load Limit (WLL).
- Markings : Every link is hard-stamped with the manufacturer’s mark, batch number, steel grade (Grade 8 or 10), and traceability code.
