| description | 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. |

Tidigare studier av belastningsbesvär hos mjölkare i mjölkgropssystem har visat att det är ett fysiskt hårt belastat yrke. De rörelseorgan som är mest utsatta är nacke, axlar/skuldror och händer/handleder. System som i huvudsak studerats i föreliggande undersökningar har varit av typen fiskbensstall och en liten del av tandemstallar. Förändringar har skett med arbetsmiljön i mjölkstallar under de senaste tio åren. Mekaniseringen har utvecklats till det bättre med automatiska avtagare och höj och sänkbart golv i de flesta av dagens mjölkstallar. Däremot har mjölkproduktionen blivit mer industrialiserad och till följd av detta mer stressbetonad. Vilket medför större risk för arbetsskador, trots rationalisering och bättre teknik. Grundläggande uppgifter till detta arbete har hämtats från besök på fem mjölkgårdar med de fyra olika mjölkningssystemen, parallell, fiskben, karusell och tandem. Mätstudier har gjorts på avståndet från mjölkare till kornas juver, samt avståndet från gropens kant till juver och gropdjup. Beräkningar har gjorts på hur mycket belastning det ligger på axelleden med hjälp av biomekanisk analys, för att utröna skillnaderna i belastningar på mjölkarnas rörelseorgan mellan de olika systemen. Det har inte visat sig vara några radikala skillnader mellan systemen vad gäller räckvidd och mekanisering i groparna. Däremot har resultaten visat hur mycket individuella variationer bland både människor och djur påverkar belastningen på mjölkaren.
