Industrial tire standards mainly include requirements for materials, sizes, quality, etc. Specifically:
Material standards: The materials of industrial tires usually include cast iron, cast steel, and steel plates. Wheels of different materials should comply with the corresponding national standards, for example, cast iron wheels should comply with GB/T9439, cast steel wheels should comply with GB/T10433, and steel plate wheels should comply with GB/T46971.
Size standards: The size standards of industrial tires depend on the use conditions and loads. For example, motor vehicles should comply with GB/T1236, railway vehicles should comply with TB/T475, and trolley vehicles should comply with MT821-87, etc.
Quality standards: The quality standards of industrial tires are closely related to the operating conditions and uses. For example, railway vehicle wheels should comply with TB/T476, and coal mining locomotive wheels should comply with JB6324, etc.
Special wheel standards: Different types of industrial tires have different standards. For example, polyurethane wheels should comply with the JB/T10907 standard, and remote control vehicle wheels should comply with the JT/T1336 standard, etc. In addition, there are some specific test methods and performance requirements: Rolling resistance test method : For electric counterbalanced forklift tires, the test method of rolling resistance is very important. Standard GB/T 42356-2023 provides four measurement methods, including tire shaft force method, drum shaft torque method, power method and deceleration method. These methods ensure that the rolling resistance of the tire is measured in a steady state, and specify strict test equipment accuracy and test conditions .
