| Sumario: | Earlier studies of musculoskeletal problems with milkers working in milking parlour
operators have shown that it is a physically demanding occupation. The extremities that are
most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in
present cases are fishbone and some tandem barns.
There have been changes in the working environment during the past ten years. The
mechanisation has been developed for the better with automatically removers of the milking
units and vertically adjustable floors in almost every daily milking barn. In other hand the
milk production are more industrialised and more related to stress today. That causes working
disorders despite rationalisation and better technical equipment.
Basic statements to this work are collected from visits at five dairy farms with four of the
systems parallel, fishbone, carousel and tandem.
Measurements have been done of the distance from milker to the udder of the cow and the
distance from the edge of the hollow to the udder. The depth of the hollow has also been
measured. Calculations have been done of the shoulder flexors by biomechanics analysis to
see the differences in loading on the milkers extremities between the systems.
Any radical differences have not been shown between the systems in matter of extent or
mechanisation. In other hand there are lots of individual variations in both humans and
animals that affect the load on the milker. |
