Rated Torque Capacity: The rated torque capacity of this swing gearbox is usually in the range of 15,000 - 30,000 Newton-meters (N·m). This torque rating is sufficient to rotate the relatively heavy upper structure of the 330D2 and 330F excavators, even when the working equipment is under a significant load. It allows for smooth and stable swing operation in various working conditions.
Maximum Torque Capacity: The maximum torque capacity that the gearbox can withstand for short periods is higher than the rated torque, often reaching up to 40,000 N·m or more. This additional torque capacity enables the gearbox to handle sudden peak loads, such as when the excavator encounters unexpected resistance during swinging, ensuring the reliability and durability of the swing system.
