Frequently Asked Questions
What is the temperature rating of Van Beest Green Pin G-4161 and G-4163 shackles?
Standard Green Pin G-4161 and G-4163 hot-dip galvanized shackles maintain 100% of their full Working Load Limit across an operating temperature range of -40°F (-40°C) up to +392°F (+200°C).
What is the difference between Green Pin G-4161 and G-4163 shackles?
The G-4161 is a standard bow shackle with a screw collar pin for fast rigging and unrigging, while the G-4163 is a safety bow shackle with a hex bolt, nut, and cotter pin for permanent or dynamic installations.
Do Van Beest Green Pin shackles match Crosby G-209/G-2130 Working Load Limits?
Yes. Green Pin Grade 6 shackles share the same metric-ton Working Load Limit ratings (0.50 t through 35 t) and nominal pin dimensions as Crosby G-209 and G-2130 shackles, with a full 6:1 safety factor.
Are the green pins on Van Beest shackles galvanized underneath the paint?
Yes. Both the bow and the alloy pin are fully hot-dip galvanized first, and the pin head is then finished in Van Beest’s signature green enamel for immediate visual confirmation from a distance.
How do you calculate side-load derating on a Green Pin bow shackle?
In accordance with Van Beest and ASME B30.26 rules, apply 100% WLL for inline pulls (0°–5°), 70% WLL for 6°–45° side angles, and 50% WLL for 46°–90° side angles.
