With the MMH Calculator (Manual Material Handling) the recommended weight limit for lifting tasks can be calculated. The calculation is based on the revised NIOSH lifting equation. This method is internationally established, and is e.g. used by Dutch Labour Inspectorate. The app is applicable for working situations with lifting tasks. After input of several characteristics of the lifting tasks, the recommended weight limit is calculated, and the associated risk is indicated. Moreover, it becomes clear how the lifting task may be improved. Please read the Info tab in the app: in some lifting situations the NIOSH method may NOT be applied.
