Application
1. Logistics Conveyor Drive
In roller conveyors at e-commerce warehouses and food processing plants, this gear motor accommodates motors ranging from 0.75 to 15 kW, delivering output torque up to tens of thousands of N·m. Its high-rigidity transmission ensures smooth operation under heavy loads and frequent starts/stops. The impact-resistant cast iron housing withstands demanding workshop environments, enabling conveyors to achieve daily material handling efficiency exceeding 100,000 items.
2. Construction Mixing Equipment Transmission
In small concrete mixers and mortar mixing equipment, the helical gear structure enables 90° angular transmission, accommodating vertical shaft installation requirements. High load capacity handles fluctuations during mixing, while low-noise operation minimizes construction site disruption, meeting construction projects' demands for equipment durability and stability.
3. Lifting Mechanisms for Hoisting Machinery
In workshop hoists and lifting platforms, the high-efficiency transmission of gear motors boosts lifting efficiency. The sealed cast iron housing prevents dust and oil contamination of gear sets, supporting lifting speeds of 3–10 m/min to deliver safe, reliable power reduction for equipment.
