BL/XL Series Shaft Input Vertical Cycloidal Gearbox adopts a high-strength cycloidal pinwheel transmission structure with vertical shaft input design, providing high reduction ratio, large torque capacity, stable operation and excellent overload resistance. The vertical input structure simplifies equipment integration and is especially suitable for applications requiring compact installation, low-speed high-torque transmission and continuous heavy-duty operation. With a typical output torque range of 100–60,000 N·m and power range of 0.12–75 kW, it is widely used in lifting equipment, mixers, conveyors, chemical machinery, construction machinery and heavy industrial drive systems.
