The roller is used to support the weight of the body of construction machinery such as excavators and bulldozers, and roll on the track (rail link) or track shoe surface of the track. It is also used to limit the track and prevent lateral slippage. When the construction machinery and equipment turn, the roller forces the track to slide on the ground. But for many products on the market, how should we choose the bulldozer roller?

The roller of bulldozer bears its own mass and working load, and its attribute is an important standard to measure its quality. The bulldozer roller belongs to one of the "four wheel belt". The four wheels in the "four wheel belt" refer to the driving wheel, guide wheel, roller, carrier wheel, and the belt refers to the track. They are directly related to the working performance and walking performance of bulldozers, and their weight and manufacturing cost account for a quarter of the manufacturing cost of bulldozers.

1. Project scale; Large scale earthwork engineering and medium and large scale open-pit mine engineering shall be analyzed, compared and scientifically calculated according to the investment scale, supporting equipment and other factors to determine the specification, model and quantity of bulldozer supporting wheels. For ordinary small and medium-sized projects, such as road maintenance and irrigation and water conservancy, only ordinary bulldozer rollers are needed.

2. Supporting conditions of the project; When purchasing bulldozer roller, consider the matching of existing equipment, including the matching of the working efficiency of excavator roller and the working efficiency of existing equipment.

3. Current funds; You should have your own budget before purchasing, and you can choose the bulldozer roller according to the budget.

As the core component of bulldozer track chassis, the performance of bulldozer roller directly affects the reliability and working efficiency of the whole machine. The selection of bulldozer roller is very important for the subsequent use. At the same time, it also needs to do some maintenance work. The purpose of regular maintenance is to reduce the failure of the machine and extend the service life of the machine; Shorten the downtime of the machine; Improve work efficiency and reduce operation cost.
