With the registered values and considering the average of the acromial height of the workers of the sector, it was arrived the results of Limit of Peso (LP) of 1,305 kg that is for the configuration currently tried in the sector the current the 30 weight would have to be significantly lesser of what kg in more than 20 times. The recommended weight limit found points as mais need improved ergonomic condition of this activity.
