G209 and G2130 Heavy Duty Rigging Shackle

Description

Product Overview

The G209 and G2130 Series Rigging Shackle (recognized across global supply chains as the Heavy Duty Anchor Shackle, and standardly specified by maritime and mining operations in Latin America as Grillete para carga) serves as the primary critical connecting link in heavy-duty hoisting, towing, and structural rigging assemblies. Drop-forged from premium, high-tensile carbon steel and coupled with heat-treated alloy steel load pins, these heavy-duty fittings are engineered to bridge the connection between lifting slings, master links, crane hooks, and heavy industrial cargo points.

By implementing strict manufacturing controls, this drop forged carbon steel shackles lineup achieves maximum grain refinement in the steel matrix, completely eliminating internal micro-cracks or cooling voids. The exterior is finished with hot-dip galvanization or a high-visibility powder coating to withstand aggressive offshore, marine, and underground mining environments. Each unit features an optimized bow configuration, allowing it to accept multi-leg sling matrices or wide webbing straps without causing dangerous crowding or uneven lateral stress distributions.

Advanced Structural Typology: Screw Pin vs. Safety Bolt Lock

To satisfy varied material handling environments and regulatory safety parameters, our industrial cargo shackle fleet is split into two specialized hardware configurations:

1. G209 Screw Pin Bow Shackles (Ancla Tipo Pasador Roscado)

Designed for rapid deployment, temporary rigging layouts, or applications requiring frequent hook-ups and disconnections. The G209 screw pin bow shackle relies on a precision-machined threaded pin that flush-mounts into the shackle ear. Operators can securely tighten or loosen the pin manually or with a standard spanner wrench right on the staging floor, accelerating field-rigging setup times.

2. G2130 Bolt Type Anchor Shackles (Ancla Tipo Perno de Seguridad)

Engineered for long-term permanent installations, structural rigging suspension, and dynamic heavy towing pathways where the load pin may rotate or vibrate. The G2130 bolt type mooring shackle features a combination of a hex head bolt, a heavy structural nut, and a split cotter safety pin. This three-stage structural defense system renders it physically impossible for the pin to back out or unscrew during dynamic movement, delivering the ultimate level of site protection.

Technical Specifications & Parameter Matrix

Certified engineering boundaries, physical clearances, and weight tolerances for the industry-standard G209 and G2130 Rigging Shackle lineage:

B2B Procurement Note: The dimensions stated above follow global standard rigging industry blueprints. Each batch undergoes rigorous testing to maintain a strict 6:1 Safety Factor (Minimum Ultimate Strength is 6 times the Working Load Limit). Procurement managers can mix G209 and G2130 orders to maximize shipyard and logistics site versatility.

Critical Capacity Management & Safe Rigging Dynamics

Rigging supervisors outfitting offshore operations or transport hubs with the industrial lifting shackles 0.5t-55t range must carefully track spatial and physical constraints:

• Pin Diameter Scaling vs. Nominal Bow Size: A critical technical aspect for crane riggers to remember is that the load pin diameter is always larger than the nominal shackle body size. For example, a 4.75-Ton shackle possesses a 3/4 inch body, but its actual alloy pin diameter is 0.88 inch. Hook attachment holes, eye pads, and wire rope thimbles must be pre-measured to ensure this larger pin can slide through smoothly.

• Deadweight to Structural Load Adjustments: When assembling heavy crane blocks, tool deadweight can severely impact manual handling. While a standard 2.00 T shackle is ultra-portable at just 0.33 kg, scaling up to an infrastructure-grade 55.00 T safety bolt shackle brings a permanent deadweight of 44.60 kg onto the rigging block. This requires auxiliary mechanical assistance simply to position, slide, and cotter-pin the hardware before lifting sequences can begin.

Industrial Applications

• Maritime Ports & Heavy Marine Towing: Shipyards and vessel operators utilize the secure G2130 bolt type mooring shackle architecture for long-term open-ocean tie-downs and heavy towing bridal arrangements. The hot-dip galvanized coating blocks saltwater corrosion, while the cotter-pin lock prevents dynamic wave vibrations from spinning the load nut loose.

• Open-Pit Mining & Heavy Equipment Extraction: Heavy industrial mining nodes across Chile, Peru, and Mexico deploy heavy-capacity 35.00 T and 55.00 T bow shackles to construct recovery tow lines for massive haul trucks, electric shovels, and tracked excavators, ensuring the linkages handle massive pulling forces safely.

• Automated Logistics Warehouses & Spreader Bars: Warehouses combine the G209 screw pin bow shackle with overhead spreader beams to manage mixed cargo picks. The wide inside bow width allows multi-leg nylon webbing slings to angle out naturally, preserving optimal load distribution.

• Structural Steel Construction & Architectural Erection: Rigging crews use intermediate 4.75 T and 12.00 T shackles to connect crane hooks to structural I-beams and prefabricated truss frameworks, relying on the fast-turn screw pins to clip and unclip loads efficiently on high-altitude staging zones.
