摘要

The paper presents the problem related to the influence of the size of the chain saw (displacement, but also power and mass) and the length of the guide bar to vibrations emitted while delimbing on the test bench. The resulting size of vibrations significantly differed from data provided by manufacturers and in most cases do not allow operator an 8-hour working time. It was also found that the vibrations with higher values usually occur during delimbing on the front handle. In the case of the parameters characterising of the chain saw it was found that they do not affect significantly the size of the vibrations emitted by the delimbing. However, in case of the length of the guide bar can tell a big impact of this parameter to vibrations occurring in the chain saw handles. The best parameters during the delimbing models are characterised by a larger group of hand-held medium-sized guides bars equipped with a medium length.
