Product Features and Advantages

As the peak model of the MSB AT Series, MS 75AT was developed for the largest mining sites and infrastructure projects. Compatible with carriers up to 100 tons, this model is the most powerful representative of non-blasting excavation. It incorporates all advanced technology features such as Oil Flow Control (OFC) Valve, Super Anti Blank Firing (SABF) System and Underwater Application (UA).

✅ OFC (Flow Control Valve): Protects the breaker against changes in hydraulic flow and stabilizes performance.
✅ Super Anti Blank Firing (SABF) System: Stops the impact when the tool loses contact, protecting internal components.
✅ All-in-One Type of Upper Bushing & Thrust Ring: One-piece design providing easy maintenance and extra durability.

✅ Original Cylinder Design: A cylinder with a round upper section and square lower section improves operating stability.
✅ 180° Rotating Housing: The housing can be rotated to prevent one-sided wear.
✅ Underwater Application (UA) & Autogrease System II (Side Mounted Refiller): Includes all required infrastructure (UA) for demanding conditions.
