D85PX-15 Bulldozer Bottom Roller

D85PX-15 bulldozer bottom roller

A bulldozer bottom roller is an essential component of the bulldozer that helps in the smooth movement of the track chain. It is a steel wheel mounted at the bottom of the track frame that supports the weight of the bulldozer and ensures smooth movement of the tracks. It is made up of strong and durable materials to withstand heavy loads and resist wear and tear.

The bulldozer bottom roller not only anchors the track chain but also determines the overall stability of the bulldozer on rough terrain. It helps in reducing the vibration and noise caused while operating the bulldozer. The roller also prevents the track chain from sagging and falling out of alignment.

Regular maintenance of the bottom roller is necessary to ensure the longevity of the bully structure. Keeping the roller lubricated and free from dirt and debris helps reduce resistance, thereby promoting smooth movement. The bulldozer bottom roller is a crucial component of this heavy machine, ensuring that it performs smoothly and efficiently on construction and mining sites.

Each track roller shell is carefully heat treated to ensure long wear life and stress resistance.

The Komatsu D85PX-15 and D85EX-15 bulldozers are two powerful machines designed to handle tough terrain and heavy loads with ease. Both models are highly efficient, making them popular choices for construction and mining applications.

One of the key differences between these two machines is their weight. The D85PX-15 weighs in at approximately 24,000 kg, while the D85EX-15 comes in at around 23,000 kg. The D85PX-15 is heavier due to the added weight of its blade and pivot shaft, which make it more stable and better equipped for dozing large volumes of material.

Another noticeable difference is the blade width. The D85PX-15's blade has a width of 3.66 meters, while the D85EX-15's blade is 3.9 meters wide. The wider blade on the D85EX-15 allows it to cover more ground with each pass, making it better suited for larger and more expansive work areas.

In terms of engine power, both models are equipped with a Komatsu SAA6D125E-5 diesel engine that delivers 264 horsepower. The engine is highly efficient and meets the required emission standards, ensuring optimal performance while also being environmentally friendly.

Both models are designed with operator comfort and safety in mind, with spacious cabins that provide excellent visibility and reduced noise levels. The cabins also come equipped with air conditioning and cushioned seats to ensure that operators remain comfortable throughout their shifts.

Overall, the Komatsu D85PX-15 and D85EX-15 are two highly efficient and reliable bulldozers that are capable of handling heavy loads and tough terrain with ease. Their differences in weight, blade width, and other features make them each unique and well-suited for different applications. Whether it is mining, construction, or other industry applications, these machines are sure to make any job easier and more efficient.
