The Horsburgh & Scott engineering team has over 135 years of experience designing, manufacturing and maintaining gearboxes in heavy duty applications around the world. We have proven design standards for gearboxes up to 5000 HP and 4 million ft-lbs. with speeds from 0.5 to 3600 rpm. If we don’t have a standard gearbox to meet your needs, we can design a custom gearbox for your specific application.
