Our dozer track components are the key system to support the full working conditions of the equipment, including track chains, carrier wheels, supporting wheels, guide wheels, drive teeth and other complete components, which are suitable for 60+ models such as Caterpillar D5-D11, Komatsu D51-D155, John Deere 650K-950K and so on, and can be precisely matched with the equipment, ranging from municipal earthmoving to heavy-duty mining. It can be matched accurately from municipal earthmoving to mining heavy-duty.
The core components adopt advanced technology: the track links are forged with 40CrNiMo alloy, and the surface is laser coated with wear-resistant layer with a thickness of 3mm, which improves the wear-resistant ability by 50% compared with the ordinary model; the body of the carrier wheel and the supporting wheel is QT700 ductile cast iron, and the bearings are made of double rows of tapered roller structure, which, together with the triple Viton oil seals, can work continuously in 1.5 meters deep mud and water under the waterproof grade of IP68; the drive teeth are made of high frequency and high speed, which are made of high quality. The gear surface of the drive teeth is quenched by high-frequency, with a hardness of HRC60, and the meshing gap with the track link is controlled within 0.1mm to avoid impact noise.
Optimized for extreme scenarios: the spacing error of the chain links of the mining model is ≤0.05mm, which can withstand 20 tons of instantaneous impact force when adapted to Carter D9; all bearings of the cold zone model are filled with -40℃ low-temperature grease, which ensures that the John Deere 850K starts to run at -35℃; the wetland model is fitted with an anti-mud ring on the guide pulley, which reduces the amount of mud and sand adhering to it by 70% when adapted to the Komatsu D65.
The whole set of components is produced according to the original installation standard, and can be installed directly without adjustment. After replacing the Volvo SD160 components in an engineering team, two people completed the installation in 6 hours, and the traction efficiency of the equipment was increased by 12%, and the maintenance cycle of the crawler system was extended from 4 to 9 months, which lowered the comprehensive operation cost by 35%.

Previously, when I mixed different brands of components, the track chain of Carter D8 was cracked in 6 months. After replacing this set of mine-specific models, 14 months of hard rock operations down, chain link wear of only 0.3mm, the drive teeth mesh smoothly, there has been no jumping teeth, more than the previous lasted 8 months, the maintenance fee alone saved 60,000 yuan.
The tracks soak in mud and water all day long when dredging fish ponds, and the previous components had to change the bearings in 3 months. This wetland model installed in the Komatsu D65, disassembled to see the bearings clean, 8 months without clearing the mud, the guide wheel rotation is still very smooth, cheaper than the original components of 30%, cost-effective is too high.
In winter -30 degrees Celsius, the previous track assembly had to bake for 1 hour in the morning before it could move. After replacing the cold zone models, John Deere 650K a fire track on the turn, bearing grease did not freeze, this half a year did not delay the snow clearing schedule, the maintenance team said that this component frost resistance absolute.
Before changing the track assembly light alignment holes will spend 2 hours, this set of Volvo SD160 special models hole position is particularly accurate, bolts directly wear, 2 people 8 hours all loaded. The two men installed the whole thing in 8 hours. After the machine was turned on and tried, the tracks did not run off, the vibration was much smaller than before, and the efficiency of the earth moving operation was increased by 15%.
