Features

The machine can operate in distance mode or rotation mode and automatically stops upon reaching the preset target.

Independent control of front and rear rollers ensures uniform wear and accurate fatigue testing.

Integrated safety sensors prevent damage in case of abnormal contact during testing.

Touch screen interface provides real-time display of speed, rotation, and travel distance, with USB/RS485 connectivity for data management.

Heavy-duty welded frame with plastic coating ensures durability and rust protection.

Optional magnetic powder brake allows adjustment of roller rotation damping for specialized testing requirements.

FAQ

1. What is this machine?

It is a fatigue testing machine for wheelchairs, used to simulate road conditions and evaluate durability.

2. What is it used for?

It tests the wear resistance of manual and electric wheelchairs under repeated rolling conditions and monitors any damage to the wheelchair structure.

3. How does it work?

The wheelchair is placed on dual rollers, which rotate at controlled speeds. Obstacles simulate road conditions, while PLC touch screen control sets the rotation or distance mode. Safety sensors stop the machine if abnormal contact occurs.

4. Why is it important?

It ensures wheelchairs meet durability standards and helps manufacturers verify design and structural performance under realistic conditions.

5. Which wheelchairs can be tested?

Manually operated wheelchairs, user-controlled or caregiver-controlled, and indoor/outdoor electric wheelchairs with up to two driving wheels and speeds under 5 km/h.
