Rigging Accessories for Crane Operations in Ports and Shipyards

Technical overview of rigging hardware for ports and shipyards: ISO container lifting lugs, high-capacity alloy bow shackles (up to 150t), and remote automatic crane hooks.

---

Port terminals and marine shipyards represent some of the most demanding operational environments for lifting gear in the world. Ship-to-shore (STS) container cranes, rubber-tired gantry (RTG) cranes, mobile harbor cranes, and shipyard drydock cranes operate in continuous multi-shift cargo cycles. In this high-tempo environment, rigging accessories must withstand massive dynamic forces, high duty cycles, salt spray, and rough quayside handling. Specifying the correct heavy-duty rigging accessories—such as container lifting lugs, automatic hook releases, high-capacity bow shackles, and motorized spreader beams—governs the throughput efficiency and absolute safety of quayside port operations across Central Africa. ## Critical Rigging Hardware in Port Terminals ### 1. ISO Container Corner Lifting Lugs Specialized forged alloy steel lugs engineered to lock directly into the standard corner castings of 20ft and 40ft ISO shipping containers: - **Top Lifting Lugs:** Designed for straight vertical lifts using a spreader beam. - **Side and Bottom Lifting Lugs:** Feature 45° or 90° angled eyes for hoisting containers using standard multi-leg sling bridles when spreaders are unavailable. - Must feature a positive mechanical twist-lock mechanism to prevent disengagement during transit. ### 2. High-Capacity Safety-Bolt Bow Shackles (25t to 150t) Connecting heavy spreader frames and project cargo slings to crane hook blocks. Must feature forged alloy construction with hot-dip galvaniza...
