- William Hackett Metric Long Thread Swivel Hoist Ring
The HA swivel hoist ring with extended bolt (metric) is a load attachment product designed for use with loads that incorporate through holes and nut fixing. It can rotate 360° around the bolt axis, as well as pivot 180°, allowing the hoist ring to orientate to the appropriate angle of lift, mitigating the risk of damage. The HA swivel hoist ring - extended bolt (metric) is suitable for both top and side mounting and maintains its full working load limit even when pulled at 90°.
Key Features
- WLL Range: 0.5t to 22.5t
- Proof Load Test: 2.5 x WLL
- Safety Factor: 4 : 1
- Temp Range: -40°C to +200°C
- Rotation: 360°
- Pivot: 180°
Additional Features
- Standards: Designed and manufactured in accordance with EN1677-1 and ASME B30.26.
- Product sizes: Available in sizes M8 to M64 and with working load limits from 0.5 tonnes to 22.5 tonnes.
- Product markings: forged bail marked with manufacturer name "Hackett" and batch number for product material traceability. Body marked with recommended torque rating and working load limits (based on 4 : 1 and 5 : 1 safety factors). Bolt marked with metric size, material grade, "HA" branding, and batch number for bolt material traceability.
- Temperature: Operational temperature range of - 40°C to + 200°C without reduction in working load limit.
- Material: Alloy steel.
- Bolt Grade: 10.9.
- Testing: Load-rated parts are subject to 100% magnaflux crack detection following heat treatment. HA swivel hoist rings are proof tested to 2.5 times the working load limit, and fatigue rated to 20,000 cycles at 1.5 times the working load limit.
- Extended bolts: Manufactured to standard lengths (bespoke bolt lengths available upon request).
