SGS Sonder Getriebe Service Industrial Gearboxes, Reducers and Components

SGS is specialized in the engineering, manufacturing and assembly of standard, special, large and customized industrial gearboxes for the mining and materials handling industries, and other applications with a demand for high power and extreme load capacities. SGS is able to offer short response and delivery times, as well as express deliveries of special and/or large gear components, and special and customized gears. Besides a centrally located 200m² office building, two manufacturing halls with a total of 4,800m² are available for assembly purposes.

The scope of drive applications that can be equipped with SGS reducers and components includes large rock and coal crushers, large and special materials-handling equipment, processing equipment, large milling machines, as well drives for special excavating equipment in the open-pit mining industry.

Gear units for the mining and materials handling industry

SGS is familiar with different types of gear units for bulk material handling plants, processing plants, heat and power plants, and the mining industry. Our products include bucket wheel reducers, excavator crawler track drives, slewing gearboxes, hoisting gear units, as well as standard or planetary gear units. Currently we provide some bucket wheel gear units with an output torque of 2,500,000Nm and a weight of 25,000kg each.

The achievement of our goals is based on a solid foundation of long-standing experiences and comprehensive know-how in the development, construction, manufacturing and assembly of special gear units for nearly all industrial applications.

Bevel helical gear units

We are currently designing special bevel helical gear units for the drive of overland conveyor systems, which have an electric motor powered with 2,700kW. The weight of one of these drive units is 49,000kg.
