Powerful Machinery manufactures forged lifting shackles for rigging, material handling, marine work, construction, and industrial lifting. Our range covers bow and Dee bodies with screw-pin or bolt-type closures, including U.S.-type, European-type, and Grade S models. Start with the shape and pin arrangement that fit the connection, then confirm the working load limit, dimensions, finish, marking, and documentation for the job.
Send us your target standard, required WLL, body and pin dimensions, quantity, and operating conditions. We will match your inquiry to the closest standard model and identify any points that need confirmation before quoting. For non-standard requirements, attach a drawing so the load path, clearances, and pin details can be reviewed together.
Choose from bow shackles for a wider connection area, Dee shackles for aligned loading, screw-pin models for connections that are opened regularly, and bolt-type models for more permanent assemblies. Open a product page for dimensions and available sizes, or send one inquiry with the models and quantities you need.
A narrow-body shackle for aligned industrial connections where jaw width, pin diameter, and inside length must match the mating hardware. Send the required WLL, size, finish, quantity, and standard so the rated configuration can be confirmed before quotation.
A wide-bow forged shackle for connections that need more room at the crown. It can suit broader sling eyes and selected multi-leg arrangements when the load is correctly seated. Confirm the WLL, pin type, dimensions, loading direction, and documentation required for the application.
A bolt, nut, and cotter Dee shackle for more secure or longer-term in-line connections. The retaining arrangement is suitable where frequent removal is not the priority. Specify the required WLL, dimensional pattern, finish, marking, testing, and certificate requirements.
A bolt-type anchor shackle combining a wider bow with a nut-and-cotter retaining system. It is intended for applications that need more crown space and a secure pin arrangement. Confirm loading conditions, WLL, size, inspection, and documentation for the exact model.
A screw-pin Dee shackle for temporary, aligned connections that are assembled and removed regularly. Check that the connecting part seats correctly between the ears and that movement cannot loosen the pin. Quote by WLL, size, finish, quantity, and required standard.
A screw-pin anchor shackle for temporary rigging connections that benefit from a wider bow. It offers quick assembly, while the pin condition and engagement must be checked before use. Send the WLL, dimensions, application, finish, quantity, and document list with your RFQ.
A Grade S Dee-pattern shackle for buyers specifying the Australian shackle standard. Use it for aligned connections after checking the rated size and fit. State the AS 2741 requirement, WLL, pin arrangement, finish, marking, test evidence, and delivery documentation in the inquiry.
A Grade S bow-pattern shackle for Australian-market lifting and rigging requirements. The rounded crown provides more connection space than a Dee body. Confirm the selected model’s WLL, dimensions, pin style, finish, markings, testing, and certificates before ordering.
Tell us what the shackle must connect, the load it must carry, and the standard your customer expects. Attach your size list or drawing, and our team will reply with the matching product options and the details that still need confirmation.
A shackle should be selected from the lift or connection—not from body diameter alone. Check the WLL marked for the exact model, the direction of loading, the space available around the bow, the size of the mating sling eye or fitting, and how often the pin will be removed. Temperature, corrosion, vibration, and required certification can change the suitable material, finish, or pin type.
A bow shackle has a rounded body that provides more room at the crown. It is commonly specified where the connection must accept a wider sling eye or more than one sling leg. The load still needs to remain properly seated, and side loading must be assessed against the manufacturer’s instructions for the selected model.
A Dee shackle has straighter sides and is generally chosen for an in-line connection. Its narrower shape helps keep a single loaded component centered, but it offers less room than a bow shackle. Use the dimensional table to check jaw width, pin diameter, and the fit with the connecting hardware.
Screw-pin shackles are practical when a connection is assembled and removed frequently. The pin must be fully engaged and monitored where movement or vibration could loosen it. A bolt, nut, and cotter arrangement is better suited to longer-term or more secure connections because the retaining system does not depend on thread friction alone. Always follow the instructions supplied for the exact shackle.
The catalogue includes forged steel shackles with finishes and dimensional patterns for different markets. Hot-dip galvanizing is often selected for outdoor or marine exposure, while stainless steel is handled in a separate product range. If your purchase must follow ASME B30.26, U.S. Federal Specification RR-C-271, EN 13889, AS 2741, or another requirement, state it in the RFQ. Compliance, testing, markings, and certificates should be confirmed for the exact model—not assumed from a similar-looking shackle.

A drawing, marked-up photo, or existing part number can save several rounds of questions. If a dimension is critical to fit, label it clearly and include the allowable tolerance. We will state the basis of the quotation so your team can compare like with like.
One enquiry can cover bow, Dee, screw-pin, bolt-type, Grade S, and stainless options.
Product selection is tied to the required WLL, dimensions, pin arrangement, and application—not a generic catalogue description.
Marking, inspection, testing, certificates, packaging, and delivery terms can be agreed before production.
Standard products and drawing-based enquiries can be reviewed through the same sales contact.
Never select a shackle by appearance alone or use it above the WLL marked for that product. The shackle, pin, sling eye, hook, and load connection must be compatible as an assembly. Inspect the body and pin before use, remove damaged or illegibly marked hardware from service, and follow the applicable standard, lift plan, and manufacturer instructions. For application-specific decisions, involve a qualified rigger or lifting engineer.
Bow Shackle vs D Shackle. A bow shackle has a wider, rounded crown and more room for a broad connection or multiple sling legs. A Dee shackle has straighter sides and is normally used for a single, in-line connection. The correct choice still depends on the exact load path, fit, WLL, and manufacturer instructions.
Use a screw-pin shackle where the connection is temporary and the pin must be removed regularly. It is not the default choice for a connection exposed to rotation, movement, or vibration that could loosen the pin. In those conditions, ask whether a bolt-type shackle is more suitable.
Begin with the required WLL, then check the dimensional table for body diameter, pin diameter, inside width, inside length, and bow clearance. Confirm that every mating component seats correctly without point loading. Do not estimate capacity from nominal size or compare shackle sizes across brands without checking the rated data.
Yes—send the required standard or market specification with your inquiry. The available size range, WLL, material, finish, testing, marking, and documentation will be confirmed for the selected product in the quotation.
Include the marking layout, finish, packaging method, quantity, and any inspection or certificate requirements in the RFQ. We will review feasibility and identify minimum quantities, tooling, samples, or approval steps where they apply.
Send the shackle type, WLL, size or drawing, pin style, material and finish, required standard, quantity, destination, and delivery target. Add operating temperature, corrosion exposure, side loading, or vibration whenever those conditions are relevant.
