Gantry Crane Gearbox

A Gantry Crane Gearbox powers heavy lifting by reducing motor speed and increasing output torque. Built from high-strength alloy steel, this speed reducer resists wear and handles frequent start-stop cycles. Its compact design performs reliably in ports, factories, shipyards, and construction sites.

Flexible Drive & Stable Transmission

Our heavy-duty drive solutions provide stable power transfer for various crane models. Flexible installation options help save space and simplify maintenance. To learn more about standard gear design rules and safety ratings, refer to the American Gear Manufacturers Association (AGMA) specifications.

Reliable Industrial Driving Components

Our industrial drive systems ensure long service life under heavy duty cycles. For a complete lifting drive configuration, you can also explore our high-performance Crane Brake systems.
