The RB30T is built for daily abuse with a hardened 40 mm steel shaft, rugged ribbed nylon-fiber reinforced serpentine belt, counter-weighted flywheel system, three-phase motor, and solid-state phase converter for consistent torque under load. Self-calibration and inner-arm calibration functions help maintain long-term measurement accuracy, while error-code diagnostics streamline troubleshooting and service. The machine also keeps the work area organized with a top weight tray, side shelving, and cone pegs for weights, cones, and tools. A full heavy-duty cone and commercial adapter kit comes included, giving shops the mounting equipment needed to start handling truck and passenger car balancing without a pile of day-one add-ons.
