Rated Torque: The input shaft is designed to transmit a significant amount of torque from the engine to the hydraulic pump. The rated torque capacity is usually in the range of several thousand Newton-meters (N·m), typically around 5000 - 8000 N·m, depending on the specific design and power requirements of the PC1250 - 7 excavator.
Speed Range: The input shaft can operate within a speed range that is compatible with the engine's output speed. Generally, it can handle speeds in the range of 1000 - 2500 rpm to effectively transfer power to the hydraulic pump.
