The RAV GTL4.140R is a versatile, microprocessor-controlled wheel balancer designed for both passenger and commercial vehicle wheels. It features self-calibration and self-diagnostics, ensuring accurate balancing with minimal setup. The machine offers specific balancing programs for static, dynamic, and ALU (light alloy) wheels. A single spin at low rotation speed provides all necessary values, with display readouts indicating out-of-balance values and their positions on the wheel. The digital caliper with an optical sensor and alloy shaft automatically stores distance and diameter measurements up to 26 inches. This balancer is ideal for workshops requiring efficient and precise wheel balancing for a wide range of vehicles.
