The TreadPlus B40 is a professional wheel balancer built for high-throughput automotive service operations. Laser sensors deliver precise rim distance and weight position readings, while the clear LED operator display guides operators through every balance cycle. Optionally paired with the QC20 quick-change clamping system for faster, hub-centric wheel mounting.
Built-in laser sensors automatically capture rim diameter and width, eliminating manual data entry errors and ensuring weight placement accuracy on every balance cycle.
