XQ-6452 Parking Brake Life Test Machine 
I. Application scope of parking brake life testing machine：
This testing machine is used for the fatigue strength test of the brakes of electric wheelchair vehicles. It simulates the repeated operation of the brakes by humans and is controlled by a touch screen PLC program. The operation is simple and it can display the number of tests, test frequency, etc. When the set number of tests is reached, it will automatically stop. It can also display the number of tests and the force value of the test.
II. Main parameters of the parking brake life testing machine:
Power supply for work: AC 120V/60Hz or as specified by the country.
Power: 950W
Test rate: Adjustable from 1 to 60 times per minute
Total number of tests: 1 - 99999999 (with a function to stop the operation upon reaching the specified number of tests)
Test space: 1200*1200*1700mm
Jig probe testing distance: 0 - 100mm (adjustable)
Test the distance for left and right movement: 1200mm
III. Advantages of the Parking Brake Life Testing Machine：
1.The stroke is adjusted by means of a magnetic cylinder sensor.
2. Microcomputer-based program control.
3. The pneumatic components are of imported brands.
4. Install a pressure stabilizing tank to better maintain the working pressure and ensure a more stable loading force.
5. The force sensor used is of high precision brand with a measurement range of 20KG and an accuracy of 0.5% of the full scale.
6. Independent central control box, facilitating operation and ensuring the durability and safety performance of the electrical equipment.
