Quick Specifications

Product Overview – The Complete Evisceration Assembly Solution

The ZYRP-PSSK1023 plastic eviscerating shackle assembly is a fully integrated poultry shackle assembly that combines the shackle body, knuckle joint, synthetic suspension rod, and stainless steel coupling pins into one pre-assembled, ready-to-install unit — purpose-designed for modern poultry evisceration lines. Unlike conventional setups that require separate sourcing and assembly of individual components, this complete poultry shackle solution arrives factory-verified, eliminating alignment errors, missing hardware, and the labor-intensive assembly process that can delay line commissioning. The CE-certified evisceration hanger is engineered specifically for the delicate demands of the evisceration stage, where birds must be securely suspended yet allowed natural articulation for optimal organ removal access. The nylon suspension rod provides a lightweight yet rigid connection between the overhead conveyor and the shackle, while the integrated knuckle joint introduces a degree of pivot flexibility that reduces the risk of carcass damage during automated transfer and indexing movements. This HACCP-compliant poultry hardware assembly is manufactured from food-grade PA/nylon, ensuring no metal-to-bird contact — a critical factor for preventing bruising, scratching, or contamination that can downgrade product quality or trigger food safety audits. Fully compatible with standard overhead conveyor rail systems, the ZYRP-PSSK1023 serves as a drop-in replacement for OEM assemblies across major slaughterhouse brands, offering a cost-effective, reliable alternative that simplifies procurement and reduces the total cost of ownership for poultry processors worldwide.

Key Features – Engineered for Evisceration Efficiency

• Complete Ready-to-Install Assembly: The poultry shackle assembly arrives fully pre-assembled with shackle, knuckle joint, suspension rod, and coupling pins — reducing installation time by up to 70% compared to piecemeal sourcing and on-site assembly. This turnkey approach also minimizes the risk of missing components or incorrect assembly that can cause line stoppages.
• Lightweight All-Plastic Construction: Injection-molded PA/nylon shackle and rod reduce the overall weight of the hanging assembly by approximately 55–60% versus all-metal alternatives. This weight reduction lowers conveyor chain tension, extends drive component life, and decreases energy consumption — measurable benefits that contribute to improved OEM poultry processing spare parts economics.
• Zero Metal-to-Bird Contact: All surfaces that come into contact with the poultry carcass are engineering plastic, eliminating the risk of bruising, scratching, or corrosion-induced staining that can occur with metal shackles. This feature is especially valuable for whole-bird and skin-on products where appearance directly affects market grade and consumer acceptance.
• Knuckle Joint Articulation: The integrated knuckle joint provides a flexible pivot that allows the suspended bird to move naturally through evisceration stations — reducing binding forces that can cause misalignment, organ damage, or line jams. This articulation also accommodates the slight variations in bird size and shape without requiring manual adjustment.
• Chemical & Washdown Resistant: Both the PA/nylon body and the stainless steel coupling pins withstand daily high-pressure washdown with aggressive sanitizers (peracetic acid, chlorine, quaternary ammonium compounds) without corrosion, pitting, or material degradation — ensuring long-term HACCP-compliant poultry hardware performance.
• Standard Rail Compatibility: Engineered to the dimensional standards of major overhead conveyor systems, the nylon suspension rod and shackle mounting geometry ensure a true drop-in replacement for existing evisceration lines — no adapters, rail modifications, or special tools required.
• Cost-Effective OEM Alternative: As a full-range poultry shackle assembly solution, the ZYRP-PSSK1023 breaks dependency on proprietary OEM supply chains, offering competitive pricing, flexible custom configurations, and reliable availability for both scheduled maintenance and emergency replacements.

Knuckle Joint and Suspension Rod – The Articulation Advantage

The nylon suspension rod in the ZYRP-PSSK1023 serves as the critical link between the overhead conveyor trolley and the shackle body. Its length is precisely calculated to maintain optimal bird elevation above the evisceration station work surface, allowing operators and automated tools clear access to the body cavity. The rod is molded from the same food-grade PA/nylon material as the shackle, ensuring consistent corrosion resistance and chemical compatibility throughout the entire assembly. At the lower end of the rod, the knuckle joint shackle provides a pivotal connection that allows the shackle to rotate approximately ±15° in the vertical plane and ±10° in the lateral plane. This controlled articulation accommodates the natural contour of the bird during organ removal, reducing the stress on the carcass that can cause muscle tearing or abdominal wall damage. The joint utilizes a stainless steel coupling pin with a positive-locking retaining clip, preventing accidental disassembly while enabling simple tool-free detachment for cleaning or replacement. The combination of the nylon suspension rod and knuckle joint creates a flexible yet stable platform that improves evisceration yield, reduces operator effort, and supports higher line speeds without compromising quality.

Stainless Steel Coupling Pins – Durability in the Pivot Zone

While the shackle and rod are all-plastic, the ZYRP-PSSK1023 strategically deploys stainless steel coupling pins at all pivot points — including the knuckle joint and the shackle-to-rod interface. These pins are manufactured from food-grade 304 stainless steel, offering excellent corrosion resistance and mechanical strength to withstand the repetitive articulation forces experienced during thousands of evisceration cycles. Unlike all-plastic pivot designs that can wear or creep over time, the steel pin maintains a precise fit within the nylon bearings, ensuring consistent joint smoothness and preventing slop that could cause erratic bird positioning. The pins are precision-ground to a surface finish of 0.8 μm Ra, reducing friction against the nylon components and extending the service life of both the pin and the bearing surfaces. A unique retention clip on each pin allows for quick removal during cleaning without requiring specialized tools, simplifying sanitation protocols. This hybrid approach — plastic for mass and hygiene, steel for strength at pivot points — embodies the CE-certified evisceration hanger's engineering philosophy of using the optimal material for each functional zone.

Applications – Tailored for Evisceration and Beyond

• Broiler & Chicken Evisceration Lines: The primary deployment environment, where the flexible knuckle joint and zero-metal contact are critical for preserving carcass integrity during organ removal.
• Poultry Slaughter & Processing Plants: Suitable for both conventional and halal processing facilities, with material formulations that meet religious and secular food safety standards.
• Automated Overhead Conveyor Systems: The poultry shackle assembly integrates seamlessly with automated evisceration robots and vision-guided tools that rely on consistent carcass positioning.
• Halal & Standard Processing Facilities: The corrosion-free, non-porous surfaces support the rigorous cleaning protocols required for halal certification and other religious/regulatory standards.
• Line Modernization & Retrofitting Projects: The drop-in compatibility makes the ZYRP-PSSK1023 ideal for upgrading legacy evisceration lines to modern hygiene and performance standards without extensive engineering changes.
• Complete Shackle Assembly Replacement Programs: As a cost-effective OEM poultry processing spare parts solution, it enables facilities to implement systematic replacement of worn assemblies, maintaining line consistency and reducing unplanned downtime.
