Crane Hoist Gearbox

A Crane Hoist Gearbox is the core transmission unit for lifting systems. It converts motor speed into high torque to ensure smooth and safe operations. Made from alloy steel with precision ground gears, this hoist speed reducer effectively resists wear and reduces operational noise.

Versatile Heavy-Duty Drive Configurations

Whether applied on an EOT crane, an overhead traveling crane, or a tower crane, it delivers stable power output. For demanding jobs, the heavy-duty drive mechanism provides reliable torque support and long service life. To learn more about standard gear design rules, refer to the American Gear Manufacturers Association (AGMA) specifications.

Reliable Industrial Driving Components

Our heavy-duty drive systems fit various industrial cranes and winches. For comprehensive drive configurations, you can also explore our high-performance Crane Wheels.
