Rated Torque: The rated torque output of the swing motor group is usually in the range of 3,000 - 5,000 Newton-meters (N·m). This torque is sufficient to rotate the relatively lighter upper structure of the 307.5 and 308SR mini excavators smoothly and efficiently, even when the working equipment is engaged in light to moderate tasks.
Maximum Torque: The maximum torque that the swing motor can generate for short periods is higher than the rated torque, often reaching up to 6,000 N·m or more. This additional torque capacity allows the excavator to handle sudden resistance or when operating on uneven terrain, ensuring the reliability and stability of the swing operation.
