JIER Marine QRH: Rigorous Standards, Fail-Safe Performance

JIER Marine focuses on developing quick release hooks (QRH) that meet the world's high standards. Our products strictly follow the specifications of the International Maritime Organization (IMO), ASTM, ISO 3823 and mainstream classification societies (CCS, DNV, ABS), and pass the 125% SWL overload test and 100% SWL manual release verification to ensure absolute reliability under extreme working conditions.

QRH Usage Scenarios

Emergency Disconnection : Vessels experiencing fires require immediate mooring line disconnection to prevent incident escalation.
Extreme Weather Response : Typhoons/sudden gales cause over-tension, risking capsizing/line failure.
Efficient Operations at Automated Ports : Container ships/Ro-Ro vessels require frequent mooring line connections/releases during fast cargo operations.
Safety Protection for Specialized Vessels : LNG/LPG carriers/chemical tankers/polar research vessels operate in extreme/high-risk conditions.
High-Frequency Operations : Tugboats/ferries/fishing vessels require daily repetitive mooring/disconnection tasks.

QRH Components

Multi-Mode Release Control：Manual/electric/hydraulic actuation enables rapid load/unloaded disconnection with reliable performance.
Intrinsic Safety Design：Non-sparking pads and anti-static structure meet ATEX/IECEx standards for explosive environments.
Smart Load Management：Real-time load monitoring with stress analysis supports wear prediction and predictive maintenance.
High-Durability Structure：Marine-grade alloy body with galvanization and IP66 sealing resists corrosion and environmental damage.
