Product Overview

Independently developed and patented marine mechanical release hook is a purely mechanical underwater release device designed for deep-sea survey equipment deployment. It has been successfully applied to submersible marker and seabed base release missions on multiple national research vessels, including Xue Long, Dong Fang Hong 2, Hai Da and Zhang Jian. Adopting high-strength heat treatment and reinforcement technology, the hook delivers extreme reliability in deep-sea, high-pressure and corrosive marine environments, serving as essential equipment for oceanographic observation and underwater engineering.

Key Features

• Pure Mechanical Structure: No electronic components, zero power consumption, extremely high stability and anti-interference capability for deep-sea operation.
• High-Strength Reinforced Material: Adopts heat-treated high-strength carbon steel and 316L stainless steel options, featuring excellent corrosion resistance and mechanical toughness.
• Precision Release Performance: Supports stable and accurate load release from 3 tons to 8 tons, adaptable to various underwater survey equipment and seabed bases.
• Proven Marine Adaptability: Successfully verified in actual offshore and deep-sea missions, fully suitable for long-term marine scientific research deployment.
• Safe & Reliable: Simple structure, failure-free release mechanism, low maintenance and high safety factor.
