At the same time, the company actively practices the concept of people-oriented, environmental protection and energy conservation, and is committed to building a harmonious and beautiful society.
The excavator carrier roller is an important component used for chain transmission and protection in excavators, usually installed on the chassis of the machine body and extending to both sides. The carrier roller mainly consists of a wheel body and bearings, which are responsible for transmitting and rotating the power of the chain. The bearings ensure the smooth rotation of the wheel body and the normal operation of the drag chain.
The Carrier Roller Excavator is usually connected to the excavator host through a chain to prevent the chain from tipping or tearing, while maintaining stability during operation. When the carrier roller is working, it can connect the chains together to form a cycle, helping the machine to work smoothly and absorb external vibrations and impacts. A good carrier roller can also reduce machine noise, reduce chain wear, and extend the service life of the machine.
When using excavator carrier rollers, regular inspections and maintenance should be carried out according to the environment and operational needs to ensure that the carrier rollers are in good working condition. If damage is detected to the carrier roller, it should be replaced in a timely manner to ensure the normal operation of the excavator and extend the lifespan of the machine.
Capable of resisting external vibrations and impacts: The carrier roller plays an important protective role in the process of excavator operation, as it can resist external factors such as rainwater, sediment, and gravel to maintain the stability and normal operation of the chain.It has the function of pressure and stretching: the carrier roller can withstand a certain amount of pressure and stretching when the chain is dragged, to ensure the stability and stability of the excavator during operation, thereby ensuring overall work efficiency and safety.
Strong adaptability: The carrier roller can adapt to various environments and vehicle needs through design and manufacturing changes. For example, the application of materials and components such as eccentric wheels, all steel wheels, cold drawn steel wires, and plastics can provide better guarantees for the performance and service life of carrier rollers.
High safety: The carrier roller is designed reasonably, with a high safety factor, and adopts high-performance bearings to ensure durability and safe and firm operation.Strong maintainability: The carrier roller is usually produced using standardized standards, making maintenance and replacement convenient. During the shelf life, the enterprise replaces damaged or worn parts with processed components, and directly replaces them on site for customer maintenance and upkeep.
