Bu çalışmada traktörlerde kullanılan mevcut teknolift mandal mekanizmalarına ergonomiklik kazandırılması ve mekanizmaya uygulanan yükün azaltılması amacıyla ve ergonomik açıdan tutma biçimleri göz önüne alınarak yeni bir teknolift mandal mekanizması tasarlanmıştır. Yapılan bu tasarım hızlı prototipleme yöntemi ile üretilerek traktör üzerindeki ergonomikliği kontrol edilmiştir. Diğer taraftan araç üzerine monte edilen yeni mekanizmanın üzerine gelen yükler dijital kuvvet ölçer ile ölçülerek teorik hesaplama sonucuyla karşılaştırılmıştır. Ölçümler neticesinde deneysel ve teorik sonuçların birbirine yakın olduğu görülmüştür. Diğer taraftan elde edilen yük değerleri bu yeni tasarımın yaklaşık %58-72 oranında daha az bir yükleme ile çalışacağını göstermektedir. Bu durum traktör başındaki kullanıcının daha az kuvvet harcayacağını göstermektedir. Bununla birlikte geliştirilen alternatif kol tasarımının kol/omuz desteğiyle ittirileceği için uzun süreli kullanımlarda herhangi bir fiziksel sorun teşkil etmeyeceği ve iş verimliliğine olumlu yönde katkı yapacağını düşünülmektedir.
In this study, a new technolift lever mechanism has been designed as an alternative in order to provide_x000D_
ergonomics to the existing technolift clamp mechanisms used in tractors and to reduce the load_x000D_
applied to the mechanism. In this context, a new technolift latch mechanism has been designed_x000D_
considering the ergonomically holding types. This design is produced by rapid prototyping method_x000D_
and ergonomic design is controlled on the tractor. On the other hand, the loads on the new mechanism_x000D_
mounted on the vehicle were measured with the load cell and compared with the theoretical_x000D_
calculation result. As a result of the measurements, it was seen that experimental and theoretical_x000D_
results were close to each other. On the other hand, the load values indicate that this new design will_x000D_
operate with a 58-72% less load. This shows that the user at the head of the tractor will consume less_x000D_
force. However, since the developed alternative arm design will be pushed with arm / shoulder_x000D_
support, it is considered that it will not cause any physical problems in long-term use and will_x000D_
contribute to the productivity positively.
