US Type Turnbuckle Features

• Strict standards and high safety factor: Follow American standards to ensure stable adjustment process and reliable in high-risk scenarios such as lifting.

• Material is corrosion-resistant and scene adaptation is accurate: Carbon steel is galvanized (zinc layer thickness ≥ 90μm), and the anti-rust life is 6-8 years in dry inland environment; 304 stainless steel is resistant to atmospheric corrosion and suitable for outdoor buildings (such as billboard support); 316 stainless steel contains molybdenum, and its salt spray resistance is 4 times that of 304, and it can be used for a long time in seawater and acid-base environments (life span of more than 12 years).

• Strengthened structure, strong bearing capacity: The middle sleeve adopts forging technology (large size) or high-strength casting (small size), and the wall thickness is 20%-30% thicker than the ordinary type. The 1" specification can withstand 40 tons of tension, which is far more than the European basket screw of the same size, and is suitable for heavy-duty tension adjustment scenarios (such as large crane traction).

• Efficient operation and wide adaptability: The sleeve is equipped with hexagonal heads or square heads at both ends, which are suitable for quick adjustment with standard wrenches, and the adjustment efficiency is 25% higher than that of European models; the threaded rods at both ends can be customized with more than 10 connection forms such as hook type, ring type, fork type, etc., which are compatible with American standard lifting rings and hooks (such as SAE J429 bolts), and can be assembled without conversion.

• Detailed design, rope protection and durability: The edges of the hook head and ring hole at the connection end are rounded (radius ≥ 2mm) to avoid wear on the rope; the root of the threaded rod is thickened (the diameter is 15% larger than the rod body), and the bending resistance is increased by 30% to prevent breakage when under force.

US Type Turnbuckle Typical applications

• Lifting and hoisting industry: wire rope tension adjustment of cranes and tower cranes to ensure the balance of the hoisting equipment; tightness control of fixed cables in container hoisting, suitable forged carbon steel models to cope with heavy loads (20-50 tons).

• Ship and marine engineering: mooring cable tension adjustment of ocean-going ships, dock crane cable fixation, 316 stainless steel models to resist seawater corrosion; safety rope and traction rope tensioning of offshore wind power platforms to adapt to high salt spray environment.

• Construction and infrastructure field: support cable adjustment of large factory steel structure, tension control of temporary traction system in bridge construction, and tensioning of high-voltage transmission towers. Carbon steel galvanized models are suitable for inland dry areas.

• Transportation field: cargo lashing rope tension adjustment of trucks and trailers (with American hooks and loops), auxiliary traction rope tensioning during railway track laying to ensure that the ropes are not loose during transportation and construction.

• Mining and Energy Industry: Wire rope tension balance of mine hoists, equipment fixing cable adjustment of oil drilling platforms, and high-strength carbon steel models are suitable for dust and heavy load environments.
