OTOMOTİV SEKTÖRÜNDE FAALİYET GÖSTEREN BİR İŞLETMEDE REBA YÖNTEMİ İLE ÇALIŞMA KOŞULLARININ İYİLEŞTİRİLMESİ

Öz

Bu çalışma, Kocaeli'deki bir otomotiv işletmesinin fırın hattında vardiya başına yaklaşık 1.600 kez tekrarlanan kauçuk-mandıren takma ve çıkartma işlemlerindeki ergonomik riskleri REBA yöntemiyle değerlendirmektedir. Manuel takma ve çıkartma işlemleri sırasıyla 10 (yüksek risk) ve 11 (çok yüksek risk) puan almıştır. Başlıca risk kaynakları gövde ve boyundaki aşırı bükülmeler, dengesiz bacak yüklenmesi ve manuel kuvvet uygulamasıdır. Kaynağında önleme yaklaşımıyla sürece mekanik bir pompa entegre edilerek fiziksel yük operatörden ekipmana aktarılmıştır. Müdahale sonrasında her iki işlem için REBA skoru 3'e (düşük risk) düşmüştür. Bulgular, yüksek tekrarlı endüstriyel görevlerde manuel iş yükünü mekanik sisteme aktaran mühendislik kontrollerinin ergonomik riski belirgin biçimde azaltabileceğini göstermektedir.

IMPROVING WORKING CONDITIONS IN AN AUTOMOTIVE INDUSTRY COMPANY USING THE REBA METHOD

Öz

This study evaluates ergonomic risks in rubber-mandrel mounting and removal operations performed approximately 1,600 times per shift on an automotive furnace line using REBA. Manual mounting and removal scored 10 (High Risk) and 11 (Very High Risk), respectively. The main risks were excessive trunk and neck bending, unbalanced leg loading, and manual force application. Following the prevention-at-source principle, a mechanical pump transferred the physical load from the operator to the equipment. After intervention, both operations scored 3 (Low Risk). The findings indicate that engineering controls which transfer manual workload to a mechanical system can substantially reduce ergonomic risk in high-repetition industrial tasks.
