HOOK ASSEMBLY FOR 110 TON LOAD BLOCK SEATRAX S72&S90 TA3277

The TA3277 Hook Assembly is a mission-critical, heavy-duty lifting component engineered to meet the rigorous demands of offshore material handling. This robust assembly forms the terminal point of the 110-ton load block system, providing a secure and reliable connection point for slings, shackles, and other lifting gear on SEATRAX offshore cranes.

Key Features & Specifications

• Safe Working Load (SWL): 110 U.S. Tons (approximately 100 metric tonnes).

• Design Factor: Manufactured in compliance with API (American Petroleum Institute) Spec 2C and other relevant international offshore crane standards (such as DNV, Lloyd’s), ensuring a minimum design factor appropriate for offshore service.

• Hook Type: High-capacity, forged steel hook with a wide throat opening to accommodate large multi-legged sling configurations. Typically features a swivel bearing mechanism to allow free rotation under load, preventing wire rope twist and load spin.

• Construction: Forged from high-strength, impact-resistant alloy steel for optimal strength-to-weight ratio and fatigue resistance.

• Safety Latch: Equipped with a heavy-duty, spring-loaded safety latch. This latch is engineered to positively retain the load sling or shackle pin, preventing accidental disengagement, a critical safety feature in dynamic sea conditions.

• Bearing System: Incorporates a large-diameter, heavy-duty tapered roller bearing (or similar) within the hook swivel assembly. This bearing is sealed and lubricated for life to handle extreme radial loads and provide smooth rotation in corrosive marine environments.

• Compatibility: Direct replacement assembly for the original hook on SEATRAX Model S72 and S90 offshore cranes configured with a 110-ton main hoist capacity. Designed to integrate seamlessly with the existing block sheaves, trunnions, and pin connections.

• Finish & Protection: The hook body is typically shot-peened and coated with a marine-grade primer or paint system for enhanced corrosion protection. Critical wear surfaces may be left uncoated.

Technical Benefits

• Maximum Reliability: Built to withstand the harsh offshore environment, including saltwater spray, UV exposure, and constant cyclic loading.

• Enhanced Safety: Integral safety latch and proven design minimize the risk of load slippage.

• Operational Efficiency: Smooth-swiveling hook allows for precise and controlled load positioning, crucial for offshore platform operations.

• Reduced Maintenance: Sealed bearing design and robust construction minimize routine maintenance requirements.

Intended Use & Environment

• Primary and auxiliary lifting operations on offshore oil & gas platforms, drilling rigs, and construction vessels.

• Service in global offshore environments, from the Gulf of Mexico to the North Sea.

• Handling of containers, pipe, machinery, and other heavy offshore supplies and equipment.

Important Notes for Procurement & Installation

1. Verification: Always verify the crane model (S72/S90), load block configuration, and pin/bushing dimensions against the OEM technical drawings or physical measurements before ordering.

2. Certification: Supplied with full material and test certificates (CMTR) as per API/ISO standards, including proof load and NDE (Magnetic Particle Inspection) reports.

3. Installation: Must be installed by qualified personnel following the crane manufacturer’s (SEATRAX) procedures and all applicable safety regulations.

4. Inspection: Requires regular inspection as per the crane’s preventive maintenance schedule and applicable regulatory bodies (e.g., API, LOLER).
