ZF Gearbox-New

This is a new ZF Model P-7300 gearbox, a heavy-duty planetary drive for concrete transit mixers. As a key component of the mixer's drum drive system, it provides the high torque necessary to rotate a fully loaded drum, ensuring a consistent concrete mix. The P-7300 is known for its robust design, reliability, and superior performance under demanding job site conditions, making it a standard choice for replacing or upgrading the drivetrain in mixers with up to a 12 m³ capacity. This gearbox features a two-stage planetary design and is a direct successor to the P-5300, sharing the same mounting pattern for easy integration.
