Emek yoğun işletmelerde ergonomik açıdan uygun olmayan bazı çalışma duruşlarıyla karşılaşılmaktadır. Üretimde bu çalışma duruşları performans, kalite, maliyet ve verimlilik üzerinde olumsuz etki oluşturmaktadır. Bu çalışmada, otomobiller için komple kablo demetleme işlemi yapan bir firmada, kablo demetleme konveyör hattı incelenmiştir. Uygun olmayan duruşların kaslarda yarattığı zorlanmayı değerlendirmek için AnyBody Modelleme Sistemi kullanılmıştır. Analizlerde gövde, omuz, kol ve bacaklarda kas-iskelet sistemi rahatsızlıklarına neden olabilecek yüksek eklem reaksiyon kuvvetleri oluştuğu görülmüştür. Bu nedenle, operatörler üzerindeki iş yükünü azaltabilecek yeni bir konveyör hattı tasarımı önerilmiştir. Önerilen tasarımdaki çalışma duruşları analiz edilmiş ve yeni tasarımın operatörlerin çalışma duruşlarını önemli ölçüde iyileştirdiği tespit edilmiştir. Ardından prototip konveyör hattı üretilerek, bu hat üzerinde de çalışma duruşları incelenmiştir. Analizler ile doğrulanan konveyör hattının imalatı gerçekleştirilmiştir. Son analizler gövde, omuz, kol ve bacaklar üzerindeki iş yükünün azaldığını göstermektedir. Elde edilen kazanımlar ortaya konulduğunda bu imal edilen prototip hattın işletmedeki diğer hatlar için de örnek olduğu ve benzer konveyör hatlarına da uygulanabileceği sonucuna varılmıştır.
