1. Product introduction
Huayan microcomputer controlled spring axial and transverse stiffness testing machine is a spring load testing machine developed for motorcycle spring manufacturing companies. In addition to having the testing functions of conventional spring testing machines, it can strictly press TB/T2211-2018 "Steel Coil Spring for Rolling Stock Suspension Devices" and European standard EN13298 test and calculate the axial stiffness, lateral displacement, lateral force, lateral stiffness, offset direction, and offset angle of the spiral steel suspension spring in the rolling stock suspension system, and output different coordinate curves.
