General Lashing Equipment · Cargo Lashing & Container Equipment
A turnbuckle designed for robust and reliable cargo securing operations, the Turnbuckle TBS-UL from MacGregor Finland Oy is a key component in ensuring safe and efficient lashing of anchor chains and mooring lines. Constructed from high-tensile forged steel with a hot-dip galvanized coating to ISO 3874 standards, this turnbuckle offers exceptional tensile strength (≥800 MPa) and hardness (35-45 HRC). The TBS-UL is part of the Turnbuckle Family TBS-3G, featuring a knob-type adjustable design that pairs seamlessly with LB-11 or LB-28 lashing bars for internal lashing applications. Common failures to inspect include issues such as locking mechanism failure, visible wear and deformation, rust and corrosion, proper corner casting fit, valid certification, and maintenance deficiencies. For example, the turnbuckle's locking mechanism should be checked for smooth operation without binding or delayed engagement. Visual inspections are crucial to identify any cracks, bent levers, or missing retaining pins. Rust and salt deposits must be thoroughly cleaned to prevent galvanic corrosion, which can compromise the integrity of the turnbuckle. Maintenance is equally important; brake lining inspection should be conducted every six months, gear oil changes every two years, and wildcat gauging during docking periods. Motor insulation tests are recommended annually to ensure optimal performance. Spare parts, such as brake linings, should be kept on board with a lead time of 3-6 weeks for timely replacements.
