Our bulldozer track chain (bulldozer track chain) covers complete components such as chain links, chain pins, bushings, etc. It is suitable for Caterpillar D5-D9, Komatsu D51-D155, John Deere 650K-850K and other mainstream models. The core components are made of 40CrNiMo high-strength alloy, which is quenched as a whole after forging and molding, and the surface hardness of the chain links reaches HRC58-62, and the abrasion resistance is more than 50% higher than that of ordinary carbon steel models.
Special optimization is made for different operation scenarios: the chain link thickness of mining model is increased by 2mm, which improves the impact resistance by 30%, and is suitable for Carter D7 to operate in hard rock area; the wetland model is equipped with three-layer Viton sealing and waterproof grade IP68, which is suitable for Komatsu D65 to operate for a long time in the muddy land; and the general-purpose model balances the abrasion resistance and cost to meet the needs of daily earth moving projects.
All track chains are reproduced in 1:1 size according to the original drawings, and the error of link spacing is controlled within 0.05mm, which perfectly fits with the drive wheel and guide wheel, and no need to polish and adjust when installing, and the replacement can be completed in 1 hour by an ordinary maintenance team. Measured data show that under the average daily operating intensity of 8 hours, the service life is 40% longer than similar products, and the comprehensive reduction of equipment maintenance costs by 35%.

The rocks in the quarry are particularly abrasive to the chain links, and the previous track chain lasted 6 months at most before it was deformed. Changed this rock model adapted to the Carter D7, the wear layer on the chain link is really strong, 14 months down not much wear and tear, the drive wheels did not rattle, saving several times downtime to change the chain of effort.
Wetland model track chain really did not choose wrong! When we use Komatsu D65 to dredge, the chain links are soaked in mud and water every day, and the previous chain was so rusty that it couldn't turn in 3 months. The seal of this one is well done, the bearing is still smooth after half a year, the maintenance master took it apart to see that no water has entered at all, the cost performance is much higher than the original.
Repair high speed bulldozing with the economic model track chain, adapted to the John Deere 650K, the average daily operation of 10 hours, the end of the 4-month period of chain link wear only 1mm, more than expected to last 1 month. The price is 30% cheaper than the heavy-duty models, small projects choose this enough to make.
The first time to change the track chain inexperienced, but fortunately the accessories according to the original size of the factory to do, the chain link alignment marking clear, according to the instructions with an ordinary wrench, I and the apprentice 2 hours to the Carter D6 for a good, boot try completely not lagging than the last time to change the other family's province of 3 hours.
