Non-contact four-wheel locator ——WAT-2000
W heel A lignment S ystem—WAT-2000
Place of origin: China
Manufacturing company: IYASAKA
Testing concepts
A platform used to measure and evaluate parameters and components such as vehicle camber, caster, kingpin camber, kingpin caster, thrust angle, steering angle, etc.
Meet the requirements of online adjustment of front beam and external inclination.
Test principles
The four-wheel positioning sensor utilizes IYASAKA independently developed 3D laser sensing technology. By employing dynamic laser illumination matrix reconstruction, it generates tire surface 3D images at 10/20 Hz frequency. This enables accurate determination of front camber and caster angles through tire 3D modeling. The system can be configured with wheel bead height measurement units for vehicle body (wheel bead) height assessment. It also supports expandable functions including axle load measurement and steering angle monitoring.

Product features
More test functionality and higher test quality
- High measurement accuracy, small repeatability error and stable operation
- The new floating mode of the drum unit has the characteristics of small friction, smooth sliding and sensitivity, which can help improve the repeatability of test data. At the same time, it also has the function of aligning the vehicle when detecting and adjusting the vehicles front lamp
- Iyasaka and Visicon are two laser options that adapt to a wide range of prices
- The modular design is simple to arrange, easy to maintain, high cost performance, low maintenance cost and use cost
- Image processing patent technology
- Servo technology is used for centering and central torque feedback
- The floating platform uses air suspension technology to minimize mechanical resistance and has higher accuracy
