Construction machinery chains

Construction machinery chains are typically made of heat-treated alloy steel with surface chrome plating to enhance wear, fatigue, and corrosion resistance. Chain widths range from 150 to 700 millimeters, with lengths from 1 to 10 meters depending on the equipment type. Dynamic load capacity per link ranges from 5 to 50 tons, and operating temperature is designed from -20°C to 120°C. Rollers and pins have 50 to 60 HRC hardness and are pre-lubricated with grease under pressure up to 5 bar.

Chains undergo precise dimensional and functional inspection, with epoxy or nickel anti-corrosion coating for harsh industrial and soil environments. Pin spacing and link pitch are designed according to ISO 1677 and DIN 8165 standards. Chain installation and tensioning are performed with hydraulic or mechanical tools, ensuring a service life exceeding 20,000 hours.
