The Josam Cam-aligner allows the user to measure any type of vehicle, including trucks with multiple steered axles, buses, agricultural vehicles, mobile cranes, military vehicles, light commercial vehicles, trailers, and semi-trailers. The Cam-aligner allows shops to perform fast alignments and quicker diagnoses, and it can compensate for road inclination, allowing it to be used on non-flat surfaces. The camera and inclinometer housings are IP54 rated for water and dust resistance. It offers a 14-hour operational life when fully charged.
