title: [The assessment of the vibration load in tractor drivers].
abstract: The assessment of the vibration loading of a group of tractor-drivers from the enterprise for melioration and erosion control is made on the basis of: measurement of general and local vibrations and noise of 5 tractors type C 100, C 100M and T 130; determination of the total vibration loading on the basis of data of measurements and average weekly hour individual engagement; comparison of the admissible values of vibration loading with the real determined at work with machines of different vibration characters at different hour engagement. A surpass of the admissible vibration loading is established which reaches up to 3.3 (at average weekly exposure to 30 hrs.) and to 4.7 hrs (at average weekly exposure 42.5 hrs.) with the tractors with higher surpass of MAC for the general vibrations. An admissible exposure for 1 day and for 1 year work for the separate tractors is determined in relation to the data for general and local vibrations and individual hour engagement.
