The operator starts by entering required vehicle data like chassis ID, wheel base and vehicle type. This can be done with a bar code scanner or by manual input. When the necessary data have been entered, the reflective markers swing up automatically.
The pneumatic locks in the floating plates placed in the floor are released and the system enters into measuring mode. The operator mounts the pre-calibrated wheel clamps with cameras onto the wheels using a magnetic click-on functionality to keep the clamps in place.
The actual measurement process starts as the operator aims the camera forward, clicks the OK-button, turns the camera to point backwards and clicks again. This click-turn-click procedure is done once for each wheel, giving the software enough input to calculate angles like toe, out of square and parallelism. Parallelism of all axles is calculated with the rear axle as reference. The End of Line system continues to produce live values all through the adjustment process
This allows the operator to adjust the wheel angles within tolerance in a very easy way by just looking at the bar graphs presented on the computer screen. When all the necessary adjustments are made, the vehicle specific data are stored in a database in relation to each chassis number. The operator demounts the equipment and the system is ready for another vehicle, this all in a matter of minutes.
The hardware and software work in unison prompting when the cameras and wheel clamps need calibrating and restricting measurements until the calibrations are complete to ensure consistent measurement accuracy.
