NACM96 Standard Link Chain Features：

• Enlarged specifications, heavy-duty adaptation. The chain ring diameter is 10-20mm (8-16mm for NACM90), the pitch is 50-100mm, and the 15-ton 10-meter chain is about 35kg (about 25kg for 10-ton NACM90). It is suitable for heavy cranes, port cranes and other equipment. For example, the 120mm pitch chain can be precisely engaged with the 40-ton American crane, while the NACM90 cannot be adapted to heavy equipment over 10 tons due to specification restrictions.

• Reinforced connection, safety redundancy. Equipped with a forged one-piece connection buckle (NACM90 is assembled), the breaking strength is consistent with the chain ring (≥1300MPa), and the connection time is ≤25 seconds (15% faster than NACM90). Double safety pins are added to prevent accidental detachment, which provides an extra safety guarantee than NACM90 in high-risk scenarios such as offshore lifting.

• Upgraded protection, environmental tolerance. The nano-ceramic coating model is resistant to salt spray for ≥1500 hours (1000 hours for NACM90 hot-dip galvanizing), and can be used for a long time in the marine high salt spray environment. The high-temperature model can withstand 200℃ (100℃ for NACM90), suitable for lifting steel billets in metallurgical plants, and the maintenance cycle is extended to every 2 months (monthly for NACM90).

NACM96 Standard Link Chain Typical Applications:

• Heavy-duty loading and unloading at ports. Ports hoist 10-15 ton containers. NACM96 chains work with quay cranes to complete 80-100 hoists per day. Its high strength can withstand the impact load caused by the shaking of the ship, and its life is twice as long as NACM90 (reducing downtime and replacement time).

• Heavy machinery manufacturing. Hoisting 12-ton machine tool beds. NACM96's high-precision chain rings (pitch error ≤0.5mm) ensure smooth hoisting, and work with heavy-duty overhead cranes to achieve 0.1mm-level positioning, while NACM90 is prone to slight deformation under heavy loads, affecting accuracy.

• Marine engineering. Offshore platforms install 5-15 ton steel structures. Nano-ceramic coated chains resist seawater corrosion. After 1500 hours of salt spray testing, the performance decay is ≤5%. NACM90 shows obvious rust in 3 months under the same environment.
