For the undercarriage system of a crawler machine, rollers are vital components. They are responsible for carrying the machine’s weight, guide the track chain, and help distribute impact and shock loads, especially when moving through uneven or high-impact surfaces. DOZCO specializes in designing and manufacturing undercarriage parts for heavy equipment. We offer single‑ and double‑flange bottom rollers as well as carrier rollers for crawler machines from 1 ton to 250 tons. We are a trusted manufacturer and global supplier of high-performance undercarriage parts for heavy equipment, including hydraulic excavators, and dozers of diagonal brace and pivot shaft type, and elevated sprocket machines. Our product range includes Caterpillar rollers, Komatsu track rollers, and other components engineered for various OEMs.

Durable Undercarriage Solutions for Construction and Mining Equipment

Track links are critical components in undercarriage systems, designed to endure the extreme demands of heavy-duty equipment, especially in mining and other high-impact environments. They work in combination with pins and bushings to form the track chain assembly that powers the movement of tracked machinery. DOZCO’s track link assembly is compatible with OEM excavators and other crawler machines.

DOZCO manufactures high-performance track link assemblies (track groups) designed to withstand the extreme demands of heavy-duty equipment. Working in combination with pins and bushings, our track links form the track chain assembly that powers the movement of dozers and excavators across challenging terrains.

Excavator and dozer undercarriages operate under constant load while moving across mud, sand, rock, and abrasive terrain. In these conditions, sprockets play a critical role by transferring power from the final drive to the track chain. When you purchase sprockets from DOZCO, you get high-quality undercarriage parts that perfectly align with the heavy equipment. Our ISO-certified products can handle continuous stress, reduce uneven wear, and keep machines moving smoothly on demanding job sites in Australia.

Excavator or Dozer undercarriage moves across different soil types, such as mud, sand, rocks, etc. The different types of surfaces can increase wear and tear on the undercarriage rollers and tracks. At DOZCO, we manufacture and supply high quality track guards in Australia. These undercarriage parts for heavy equipment protect the track rollers of the excavator from these materials. We maintain OEM standards when manufacturing track guards, so they perfectly fit with brands like Caterpillar, Kobelco, Komatsu, Hitachi, etc.

DOZCO manufactures high-performance track shoes engineered to deliver superior traction, flotation, and stability for dozers and excavators. As the only undercarriage component in direct contact with the ground, track shoes are critical to machine mobility, durability, and overall service life.

Whether you operate in muddy fields, rocky mines, or paved construction sites, DOZCO track shoes ensure maximum ground engagement and reduced downtime.

In the heavy-duty sector, idlers are reliable undercarriage parts. These undercarriage parts ensure smooth redirection of the track from the sprocket to the front of the frame. DOZCO manufactures high-quality undercarriage parts for heavy equipment. This includes excavator idler wheels, along with front idler assembly and rear idler assembly for dozers, designed to guide the track chain and maintain proper alignment. The front idler is a large wheel at the front of the track frame. It acts as a pivot point, redirecting the track chain back toward the sprocket. A rear idler, on the other hand, is located at the rear of the undercarriage. It makes sure that the tracks are properly aligned and tight to avoid the risk of derailment during operation
