About Heavy Duty Industrial Gearboxes
Heavy-duty industrial gearboxes are engineered for the most demanding operating conditions — continuous 24/7 operation, extreme shock loads, abrasive environments, and high-temperature applications. These units feature oversized components, reinforced housings, advanced sealing systems, and case-hardened gear teeth to deliver reliable service life in conditions that would quickly destroy standard industrial reducers.
We supply Tailong heavy-duty gearbox series for mining, steel mill, cement plant, and power generation applications. Output torques range from 1,000 Nm to 500,000 Nm with input powers from 1 kW to 500 kW. Every heavy-duty unit is custom-engineered to your specific application requirements.
