The new Crosby Easy-Loc Bow Shackles eliminates the need for nuts and cotter pins in heavy lift applications and is much faster securement.
Shackle bolt threads can become clogged with mud, dirt and other debris, and can need cleaning before the nut can be fitted, a cotter pin then needs to be fitted often requiring hand tools, to make sure this is done correctly.
The Easy-Loc shackle works in three simple steps
- Push the release buttons simultaneously to open the collar.
- Slide the pin through the shackle.
- Re-attach the collar to the slotted section of the bolt to re-engage.
The Easy-Loc collar is robust and is manufactured from 316 Stainless steel, which reduces rust and corrosion. The wide grip handle of the pin allows for easy grip and installation.
G-2140E meets the performance requirements of Federal Specification RR-C-271F, Type IVA, Grade B, Class 3, except for those provisions required of the contractor.
- Quenched and Tempered.
- Forged Alloy Steel 200 through 300 metric tons. Meets the performance requirements of Grade 8 shackles.
- Working Load Limit is permanently shown on every shackle.
- 200, 250, and 300 metric ton shackle bows are Dimetcoted; pins are Dimetcoted and painted red.
- Sizes 1-1/2 and larger are RFID-equipped.
- Approved for use at -40 degrees C (-40 degrees F) to 204 degrees C (400 degrees F).
- Shackles are Quenched and Tempered and can meet DNV impact requirements of 42 joules (31 ft-lbs.) at -20 degrees C (-4 degrees F).
- All sizes are individually proof tested to 2.0 times the Working Load Limit.
- Refer to page 88 for Crosby COLD TUFF® shackles that meet the additional requirements of DNV rules for certification of lifting applications - Loose Gear.
- Shackles are provided as follows: Serialised bolt and bow, Material certification (chemical), and Magnetic particle inspected. Certification must be requested at the time of order.
- Meets or exceeds all requirements of ASME B30.26, including identification, ductility, design factor, proof load and temperature requirements. Importantly, these shackles meet other critical performance requirements, including impact properties and material traceability, not addressed by ASME B30.26.
- Type Approval certification in accordance with ABS 2007 Steel Vessel Rules 1-11-17.7 and ABS Guide for Certification on Cranes is available. Certificates are available when requested at the time of order and may include additional charges.

Note: Maximum Proof Load is 2.0 times the Working Load Limit. For sizes 30 through 175 metric tons, the Minimum Ultimate Load is 5 times the Working Load Limit. For 200 through 400 metric tons, the Minimum Ultimate Load is 4 times the Working Load Limit. For Working Load Limit reduction due to side loading applications, see page 94 ('Downloads' tab above).
