Mooring Winch · Anchor & Mooring Equipment
Designed to provide robust anchoring and mooring solutions, the Twistlock Foundation TF-4 (4235-110-14-B) Quadruple, with elongated Hole, is a critical component in MacGregor Finland Oy’s lineup of maritime equipment. This foundation supports anchor chains and mooring lines, offering a brake holding capacity that can withstand up to 500 tonnes on the first layer, ensuring compliance with ISO and classification society standards. The load capacity ranges from 5 to 300 tonnes, making it highly configurable for various vessel needs. The windlass system, whether equipped with or without a chain stopper, is engineered to meet stringent safety requirements. When used with a chain stopper, the brake must withstand at least 45% of the chain cable's breaking strength, while the figure increases to 80% for systems without a chain stopper. The drum configuration can be single, double, or triple, and it is available with either a modular hydraulic power unit (HPU) or a full electrical drive. Maintenance is crucial for ensuring the longevity and reliability of the Twistlock Foundation TF-4 (4235-110-14-B). Regular inspections should include brake holding capacity tests, chain wear assessments, and checks for hydraulic system contamination. Spare brake linings should be kept on board due to a lead time of 3-6 weeks. Additionally, gear oil changes are recommended every two years, and wildcat gauging should be performed during docking. Annual motor insulation tests further ensure the system's optimal performance.
