Baggage handling systems at airports such as that in Los Angeles operate almost 24/7, but they do not run continuously. Time and again, they are brought to a halt and then need to be started up again. Sometimes a lot of baggage, and thus a heavier load, needs transporting on the conveyor belt; other times it's less – presenting a major challenge for the drive technology involved.
To cope with the high breakaway torque required, the asynchronous motors used till then for operation and the far lower nominal torque after start-up were completely disproportionate and inefficient. The resulting accumulation of heat left the operators no choice but to fit expensive external cooling alongside the drive technology. This measure also increased the noise level, which caused both a predicament for staff at the Los Angeles airport and spiraling costs for American Airlines.
However, once SEW‑EURODRIVE conquered the market with its mechatronic drive technology, easy and efficient solutions became available to overcome these kinds of difficult conditions. Another ground-breaking development occurred in 2013, when our subsidiary in Lyman, South Carolina, entered into a partnership with CAGE Inc., a leading U.S. consultancy firm for baggage handling systems, headquartered in Irving, Texas.
