Caster Radial Fatigue Tester
The Caster Radial Fatigue Tester is designed to evaluate the walking durability and fatigue performance of industrial casters, office chair casters, and swivel wheels. The machine uses a motor-driven turntable and applies load via weights, with a PLC touchscreen control system to set travel distance, speed, and load while automatically recording test data. This ensures high precision, repeatability, and safety during testing.

Test Principle
The machine drives the caster wheels on a motor-driven turntable under specified load and speed conditions. Obstacles simulate uneven surfaces while the load sensor monitors the force applied to the wheel. When the travel distance, time limit is reached, or the caster fails, the PLC system automatically stops the test. The results reflect the material wear resistance, structural stability, and service life of the casters.
Operation Instructions
(1) Secure the caster in the test fixture, ensuring stability.
(2) Connect the power and start the PLC touchscreen interface.
(3) Set test parameters: travel distance, speed, load, and obstacle height.
(4) Start the test; the motor drives the turntable and the caster traverses the obstacles.
(5) Monitor real-time load, speed, and travel data.
(6) The system automatically stops when set conditions are reached or the caster fails.
(7) Regularly inspect fixtures and turntable; keep them clean and lubricated.
Test Procedures
(1) Install the caster in the test fixture and secure firmly.
(2) Set load, speed, travel distance, and obstacle height.
(3) Start the test; the caster moves continuously on the turntable over obstacles.
(4) Monitor load and speed to ensure stable testing conditions.
(5) The system automatically stops at completion or upon caster failure.
(6) Record test data, including total travel distance, load profile, and failure conditions.
(7) Analyze results to evaluate caster durability and structural reliability, then generate a test report.
Maintenance Information
(1) Inspect fixtures, turntable, and sensors regularly.
(2) Keep moving parts clean and lubricated.
(3) Periodically verify PLC and sensor calibration.
(4) Ensure power connections and cables are intact and secure.
