General Lashing Equipment · Cargo Lashing & Container Equipment
Part of MacGregor’s robust lineup of marine cargo securing solutions, the Turnbuckle TBS-3G/..FB-CN is designed for medium-capacity applications involving anchor chains and mooring lines. Constructed from high-tensile forged steel with a hot-dip galvanized coating per ISO 3874, this turnbuckle offers a tensile strength of at least 800 MPa and a hardness range of 35-45 HRC. The Turnbuckle TBS-3G/..FB-CN features a knob-type adjustable design, making it easy to pair with LB-11 or LB-28 lashing bars for internal lashing systems. Routine maintenance is crucial to ensure the longevity and reliability of this equipment. Common failures include issues such as locking mechanism stiffness, visible wear, corrosion, and improper corner casting fit. Regular inspections should verify that the turnbuckle can rotate smoothly without binding, that there are no cracks or deformations in the head and shank, and that all surfaces remain free from rust and salt deposits. The galvanized coating should be inspected for pitting, and any severe corrosion should prompt a measurement of the coating thickness. For optimal performance, MacGregor recommends keeping spare brake linings on board with a lead time of 3-6 weeks. Additional service notes include biannual brake lining inspections, annual motor insulation tests, gear oil changes every two years, and wildcat gauging during docking. This comprehensive maintenance regime ensures the Turnbuckle TBS-3G/..FB-CN remains a reliable component in any marine cargo securing system.
