The Green Pin Standard — Forged Performance for Industrial Liftings

Green Pin is the premium product line of Royal Van Beest, a manufacturer specializing in forged rigging hardware for heavy lifting, transport, and mooring applications. Since 1922, the company has focused exclusively on connection hardware designed for demanding environments where strength, durability, and traceability are essential.

Every Green Pin shackle is hot-forged from high-tensile alloy steel, then quenched and tempered to produce a uniform grain structure that improves fatigue resistance and impact strength. Each unit is individually proof tested at twice the Working Load Limit (WLL) and permanently marked with heat number, WLL, and manufacturer identification to ensure full lifecycle traceability.

Green Pin products are designed to meet or exceed major international standards including EN 13889, ASME B30.26, and Federal Specification RR-C-271. Selected models carry DNV Type Approval and CE marking, supporting compliance in offshore, marine, and regulated industrial environments.

As an authorized distributor, Holloway Houston maintains extensive inventory and provides technical support for product selection, load calculations, and rigging configuration. With in-house proof testing and documentation capabilities, Holloway supports both standard lifting operations and complex engineered lifting systems.

Green Pin Products Available at Holloway Houston

Screw Pin Dee Shackles

Designed for straight-line loading, screw pin dee shackles maintain load alignment along the pin axis. These are commonly used for single-leg sling connections and chain terminations where frequent assembly and removal are required. Forged alloy steel construction with removable screw pin. Available in Working Load Limits from 0.33 to 150 tons.

Bolt Type Dee Shackles

Bolt type dee shackles include a nut and cotter pin to prevent pin rotation or loosening. They are specified for permanent or semi-permanent rigging, overhead lifting, and applications where connection security is critical. Manufactured from quenched and tempered alloy steel with corrosion-resistant pins.

Bow Shackles

Bow shackles provide increased internal width to accommodate multiple sling legs or angular loading. Available in screw pin and bolt type configurations. Commonly used in multi-leg sling assemblies, spreader beam connections, and lifting systems where load direction may vary.

Super Bow Shackles

Engineered for heavy lifting and offshore mooring, super bow shackles provide expanded geometry for large-diameter wire rope, chain, and multi-point connections. High-capacity designs extend beyond 400 tons WLL, with DNV-approved variants available for marine installation.

ROV Shackles

ROV shackles are designed for subsea installation using remotely operated vehicles. Features include extended handles and controlled pin geometry for underwater handling. Common applications include offshore pipeline installation, mooring systems, and deepwater infrastructure.

Hooks and Lifting Points

Green Pin also manufactures forged lifting hooks and swivel lifting points for secure load attachment. Swivel lifting points allow 360-degree rotation under load, reducing side loading and improving alignment in dynamic lifting conditions.
