workshops
Flexible tyre changing for trucks, buses and industrial vehicles
SMT56 and SMT56A are semi-automatic tyre changers engineered for intensive professional use, offering the perfect combination of versatility, robustness and operational flexibility. Designed to handle a wide range of truck, bus and industrial vehicle tyres, they deliver reliable performance in demanding workshop environments.
Both models feature automatic tool carriage movement, ensuring fast and precise positioning during operations. The two versions provide different levels of automation: SMT56 offers manual tool arm control for maximum operator interaction, while SMT56A integrates automatic tool arm movement, reducing effort and increasing productivity.
With an extended clamping capacity up to 56” (with optional extensions) and a multi-position clamping system, these machines guarantee maximum adaptability to different rim types, including grooved and split ring rims commonly used in heavy-duty applications.
SMT56 and SMT56A represent a reliable and scalable solution for workshops that need flexibility, durability and consistent performance in daily truck tyre service operations.
