ANTHROPOMETRIC DATA FOR ERGONOMIC DESIGN OF PEDAL OPERATED MULTI CROP THRESHER IN BORNO STATE, NIGERIA
In this study a favorable relationship between pedal operated multi crop thresher and the operator’s comfort is examined. An anthropometric survey was conducted to determine the anthropometric data in order to reduce and eliminate stresses of the pedal operated multi crop thresher operators in Borno State, Nigeria. The anthropometric data were collated from various individuals within the ages of (18 to 45) years from Borno, Nigeria. A total of 90 operators comprising of sixty (60) males and thirty (30) females were measured. Measuring instruments such as weighing balance, stadiometer, digital Vanier caliper and flexible tape were all used during the measurement which contains 11 different human body dimensions on standing and seating anthropometric positions. The obtained data were collated and analyzed statistically into mean, standard deviation, 5th and 95th percentiles. The mean age, stature and mass of male operators were 31.4 ± 3.7 years, 170.52 ± 9.93cm and 65.5 ± 4.9 kg, respectively while the corresponding parameters for female operators were 24 ± 4.1 years, 166.1 ± 5.19 cm and 52.8 ± 3.71 kg. The percentile values of male operators have been found for 5th (167.1cm) and 95th (181.3cm) percentile stature respectively while the corresponding parameters for female operators were 5th (153.4cm) and 95th (168.7cm) percentile. The results obtained indicated that males have greater anthropometric dimension values than the females. The outcome of this research will be useful in the design and manufacturing of pedal operated multicrop thresher. It was recommended that for all machines construction anthropometric data should be incorporated for appropriate design and construction of machines.
