1" Standard Bow Shackle with safety screw pin, type JB, WLL 8.5 tons, Anchor Shackle
Screw Pin Anchor / Bow Shackles
Product Description
Bow shackles and anchor shackles are both used interchangeably and
refer to a type of shackle with a larger, round “O” shaped
bow. On a screw pin bow shackle, a threaded pin is inserted through the
ears and tightened down. They are not recommended for permanent or long-term installations.
The shackles have a large rounded shape that allows them to take loads from many
directions without developing significant side load. That makes them ideal for use with multiple-leg slings, connecting
slings to load rings, and accommodating a wider strap. However, reduction to the WLL must be accounted for when used in a side-loading situation.
The screw pin configuration is best for use in applications that
are temporary, or require repeated and/or quick connections and
disconnections.
Be aware that a live line, such as a sling being used in a choker
hitch configuration, can cause the screw pin to be rotated,
torqued, or twisted which can cause the pin to unthread itself.
Always tighten the pin prior to each lift. When using a screw pin shackle, the screw pin threads shall be
fully engaged, tight, and the shoulder should be in contact with
the shackle body.
Main features:
- All screw pin shackles are quenched and tempered, with high
quality carbon steel shackle bows and alloy steel pins.
- Shackles bows are all hot dip galvanized, screws pins are painted
yellow or customized upon request.
- Meets or exceeds all requirements of ASME B30.26-2004 and
RR-C-271D.
- Proof Load is 2 times of the Working Load Limit. Minimum Breaking
Load is 6 times of the Working Load Limit.
