Earth-moving machines calculator
This calculator is a tool for risk assessment for operators of earth-moving machines to comply with the requirements of the Noise and Vibration Ordinance on exposure to whole-body vibration.
You can calculate and document the daily vibration exposure value A (8) of these employees. If the driver performs different tasks or operates several machine categories, you can include working cycles up to a total duration of 12 hours in the calculation.
The data of the selectable machine groups are based on the averaging of measured immission values (ISO/TR 25398).
For other acceleration values – e.g. from user manuals or own measured values - please use the WBV load calculator of the LAVG (such load calculators are also available for hand-arm vibration and Noise). For information about operating the calculator, see EXPLANATIONS.
