Versatile and powerful industrial gear (IG) units have been supplied to an ongoing coal terminal expansion project in South Africa.

“The introduction of our X-Series IG units has seen our relationship reach new heights over the past five years, from the initial supply of a few smaller geared units to this client,” Sew-Eurodrive Durban Branch Manager Casparus de Jager, comments.
For this particular project, Sew-Eurodrive supplied its X-170, X-180 and X-210 IG units. “The order for a number of X-210 industrial gearboxes was placed with us ahead of some tough competitors, with the scope of work including load testing at our Durban branch,” Casparus adds.
The reliability and availability of the drive unit is critical in conveyor belt applications, as some conveyor belts only run occasionally, while others operate 24/7. “This series provides robust, high-torque drive solutions to meet the challenging requirements of such systems.
“Our modular concept focuses on providing the correct IG units for conveyor belt systems, even in tough operating conditions and high ambient temperatures. This means a reduction in total operating costs for our customers, as well as reduced maintenance costs,” says Casparus.
Maximum flexibility
The X-Series has a torque range from 6.8 kNm to 475 kNm. It also features a large number of accessories to allow for maximum flexibility in meeting the diverse requirements of a range of industries, and a wide range of gear ratios for helical and bevel-helical gear units.
Nearly any mounting position or shaft arrangement on a driven machine can be implemented. A reversible gear unit housing also facilitates variable installation. Operational safety and ease of maintenance have been taken into account in terms of the robust housing, low-noise gearing and cooling system in particular.
“Efficient project planning tools, including the generation of 2D and 3D drawings, as well as predefined drive packages for conveyor drives and bucket elevator drives, are also available,” Casparus highlights.
Elevators
The X-Series for belt conveyors comprises three-stage helical-bevel gear units with special, horizontal housing for improved heat dissipation and increased cooling capacity, thanks to an efficient fan concept. This means that external cooling units and a larger gear unit are no longer necessary in most applications.
Applications include the cement and construction materials industries, and surface and underground mining.
The series is also available for bucket elevator drives, which are conveyor systems that transport bulk materials vertically. Here a high drive output is essential, depending on the bucket capacity and the lifting height. In addition, a directly-mounted auxiliary drive is used for slow movement of the bucket elevator, when the main motor is switched off.
