T/HNJB 1-2019 Circulating chain for parking equipment
Basic Information
Scope
Main technical content: This standard specifies the terms and definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of "Recycling Chains for Parking Equipment". 2.1 The technical requirements or processing requirements for each component are differentiated according to the load-bearing capacity of the parts in the structure, and the heat treatment hardness requirements are adapted to the wear resistance of the load-bearing parts. 2.2 The accuracy requirements for different lengths are specified based on the assembly of the pitch, the total length of the chain, and the pitch of the connecting plates, as well as their application in equipment. 2.3 The assembly standard stipulates the assembly techniques for chains, and details the requirements for the assembly components' qualified status, surface cleanliness, and critical dimensions. It also provides guidance on lubrication, rotational flexibility, and abnormal noise during assembly. 2.4 The test methods specified in the standard include running tests and tensile tests. The application of the product in equipment should be collected, and corresponding running and tensile tests should be conducted.
