Car wheel radial load fatigue testing machine

I. Equipment Name: Car Wheel Radial Load Fatigue Testing Machine

II. Equipment Model: SD-LDP-30    Two Stations

III. Implementation Standards:

QC/T 221 Performance Requirements and Test Methods for Automotive Light Alloy Wheels

GB/T 5334-2005 Performance and Test Methods for Passenger Car Wheels

IV. Purpose of the Car Wheel Radial Load Fatigue Testing Machine: The computer-controlled wheel radial load fatigue testing machine is primarily used to test the radial load fatigue performance of wheels.

Jinan Shangdi Electronic Technology Co., Ltd. is dedicated to the research, development, and production of wheel testing equipment. The car wheel radial load fatigue testing machine is a standard device for automotive wheel testing. It primarily simulates the condition of a vehicle under load to test the fatigue resistance of the wheel hub during prolonged operation.
