The TBM/550 is a universal hand spin wheel balancer for car, truck and bus wheels, particularly suitable for mobile service. The shaft height is adjustable by handle and is even suitable for the heaviest commercial vehicle wheels, without the need for a lift. The base is fitted with two wheels facilitating the handling and movement of the balancer, making it particularly suitable for mobile service, for example on a racetrack. The data arm automatically measures the wheel distance and diameter, and the Aludata program resolves all the problems of balancing aluminium rims. The balancer is equipped with a 12v battery and has a full working life of about 16 hours.
