Ball guardrails and aluminum rail guardrails are commonly used protective conveyor accessories, which are used to prevent the vibration caused by the high-speed operation of the production materials during the conveyor production process from scattering to the motor box and stainless steel chain transmission parts, affecting or reducing the transmission performance of the conveyor accessories. Therefore, the conveyor guardrail can play a good role in safety and protection in the maintenance of the conveyor. At the same time, it can maintain a long service life of the guardrail, which saves a lot of money for the production company in the maintenance of the conveyor. In addition, in the curved parts or diversion and confluence parts of various conveying systems, guardrails can also be made on both sides of the conveyor body to play a guiding role in the power transmission of the conveyor. It can be imagined that the guardrail series is a very important component in the conveying machinery and equipment products, and it is also one of the indispensable conveyor accessories.
