Abstract


Abstract
The paper deals with the field data study using the sample survey for productivity enhancement and ergonomic improvement of manual aara machine activity. The domestic and industrial use of wooden products is prevalent since many decades and centuries. The wood obtained by cutting trees is in irregular shape and size. The Saw mills popularly termed as Aara Machine are used to convert the raw wood logs into perfectly size and shapes. The belt saw is used to cut the huge log of wood in the form of bars, beadings, blocks, etc. The activity involves a rotating belt saw and the log of wood is fed manually by mill workers. The process involves large amount of human movements and the operating loads and conditions are at par level. Several problems are reported from the workers regarding health issues such as carpel tunnel syndrome, back pain, neck pain, breathlessness and many more. The approach is to evaluate the criticality of activity and improving the activity by application of ergonomics.

Keywords: Sawmill, repetitive motion, Carpal Tunnel syndrome, back pain, neck pain, breathlessness
