VIS has been developed to assist workshops, fleets and enforcement institutions to ensure safe and efficient vehicle operation and to make sure vehicles meet and exceed FMCSA and Commercial Safety Alliance standards.

The standard VIS Check consists of a hydraulic power pack which runs the rollers for the brake tester section, the shaker plates and lifting jack in the road simulator section. The roller section is fitted with eight load cells that measure weight and two strain gauges that measure torque (brake force). By measuring weight and torque the VIS Check is able to calculate the performance of a vehicles brakes’.

The VIS Check uses software and firmware written and developed by VIS engineers to calculate and interpret the data from the load cells and strain gauges and translate it to allow users to establish and maintain a database history on all vehicles tested on the VIS machine. The software also aids in the creation of a detailed report to the customer or driver on the condition of the vehicle.
