PMP PMB Series Concrete Mixer Truck Hydraulic Reducers

Product Overview: The PMP PMB Series Reducer is the global benchmark for concrete mixer truck drive systems. As a highly integrated planetary gearbox, the PMB series is specifically engineered to power mixer drums ranging from 6m³ to 16m³. This featured selection covers core specifications: from the classic PMB6.0 and PMB6.5R120, mid-to-large capacity PMB7.1, PMB7.8, and PMB8.0SP, to heavy-duty designs like PMB7Y120 (7YR120), PMB9Y140, and PMB9YSP. Renowned for its extreme vibration resistance and high torque output, the PMB series ensures smooth drum rotation under various road and job site conditions.

Key Technical Advantages:

• Highly Integrated Design: The gearbox housing is perfectly compatible with mainstream hydraulic motors, offering a compact footprint that saves valuable chassis space.

• Heavy-Duty Planetary Gearing: Hardened gear sets are designed to withstand massive inertial impacts during drum startup, braking, and discharge reversals.

• Superior Sealing & Protection: Equipped with high-performance combined oil seals to effectively exclude mud, dust, and moisture, protecting internal bearings from contamination.

• Versatile Ratio Options: Available in various reduction ratios (e.g., R120, R130, R140) to precisely match the speed requirements of different drum volumes.

• Low Noise & High Efficiency: Optimized gear meshing technology reduces operational noise and enhances mechanical transmission efficiency, contributing to lower vehicle fuel consumption.

• Target Applications: 6m³ to 16m³ concrete mixer trucks and mobile concrete pumping units.
