European Type D Shackle Stainless Steel With Round Pin For Marine Lifting & Industrial Rigging Webnet

European Type D Shackle – Stainless Steel with Round Pin for Marine Lifting, Industrial Rigging & Webnet

1. Product Description

The European Type D Shackle is a high‑strength, corrosion‑resistant stainless steel shackle designed for marine lifting, industrial rigging, safety net (webnet) connections, and heavy‑duty towing. It features a classic D‑shape body with a round pin and a safety bolt pin option, manufactured to meet European standards for reliability and performance. The shackle is hot‑dip galvanized for added corrosion protection and is available in a wide range of sizes from 3 mm to 32 mm, with breaking loads up to 38,000 kg.

Ideal for demanding applications in marine environments, construction hoisting, vehicle recovery, and webnet tensioning systems, this D shackle combines superior strength, easy operation, and long‑term durability. Each unit is 100% load tested and can be customized in size, packaging, logo, surface finish, and material (stainless steel 304/316 or carbon steel with galvanized coating). Free samples are available for quality verification.

• Round pin with safety bolt pin option – Secure connection, prevents accidental pin loosening under vibration or dynamic loads.

• High breaking load – Sizes from 3mm to 32mm, breaking loads from 400kg to 38,000kg, suitable for light to heavy lifting.

• 100% load tested – Each shackle is proof‑tested to ensure reliability and safety.

• Fully customizable – Size, packaging, logo, surface finish, and material can be tailored to customer requirements.

• Free samples and small orders accepted – Low MOQ for trials and project verification.

• Wide applications – Marine lifting, industrial rigging, towing, webnet fixing, construction, and vehicle recovery.

5. Applications

The European Type D Shackle is used in a variety of demanding fields:

• Marine lifting & mooring – Anchor chain connections, dock lines, towing bridles, ship deck securing.

• Industrial rigging – Overhead crane slings, hoist attachments, load binding, machinery lifting.

• Webnet (safety net) systems – Tensioning and connecting stainless steel webnets for fall protection, animal enclosures, and architectural mesh.

• Vehicle recovery & towing – Tow straps, winch lines, recovery rings, and truck lashing.

• Construction & hoisting – Steel beam lifting, concrete panel rigging, scaffolding ties.

• Mining & offshore – Heavy‑duty chain connections, equipment anchoring, and safety lines.

6. Technical Principles

6.1 Material & Strength

The shackle is forged or precision cast from high‑grade stainless steel (304/316) or carbon steel. The material provides high tensile strength, ductility, and fatigue resistance. The European type D design distributes the load evenly along the curved body, minimizing stress concentration at the pin hole.

6.2 Safety Factor

These shackles are designed with a typical safety factor of 4:1 or 5:1 (breaking load vs. working load limit). For example, a shackle with a breaking load of 10,000 kg has a safe working load (SWL) of approximately 2,000–2,500 kg, depending on application and local regulations.

6.3 Round Pin & Safety Bolt

The round pin allows quick insertion and removal without tools. The optional safety bolt pin (with a cotter pin or lock nut) prevents the pin from rotating or backing out under vibration, ensuring the shackle remains securely closed even during dynamic lifting or towing.

6.4 Corrosion Protection

Stainless steel (especially grade 316) offers excellent resistance to saltwater, chemicals, and humidity. For carbon steel versions, hot‑dip galvanizing provides a thick, durable zinc coating that protects against rust in harsh outdoor environments.

6.5 Load Testing

Each shackle is proof‑loaded to 100% of its rated breaking load, verifying structural integrity. A permanent marking (size, grade, and load rating) is often stamped on the body for traceability.
