Quick Release Hook · Anchor & Mooring Equipment
Hydraulic release hooks are essential components for secure and reliable anchoring and mooring operations. MacGregor’s MG-QRH Hydraulic Release Hook is designed to handle a safe working load of 150 tonnes, making it suitable for anchor chain and mooring lines. The brake holding capacity of the hook can withstand up to 500 tonnes on the first layer, ensuring compliance with ISO and classification society standards. For windlasses equipped with a chain stopper, the brake must hold at least 45% of the chain cable's breaking strength, while for those without, it must withstand 80%. The MG-QRH Hydraulic Release Hook is compatible with various drum configurations, including single to triple drums, and can be driven by a modular hydraulic power unit or a full electrical drive. Regular maintenance is crucial to ensure the hook’s performance. Brake holding capacity should be tested using a brake testing kit or torque spanner method, with the primary brake required to hold at least 60% of the ship's design MBL. Inspections for wear, corrosion, and hydraulic system contamination are essential to maintain efficiency. Spare brake linings should be kept on board due to a lead time of 3-6 weeks, and seals should be replaced every three years to prevent issues. Protecting control cables from UV exposure is also recommended to ensure longevity and reliability.
