The needs to comply with the rules push the companies to have at their disposal a 1° level ergonomic analysis system to evaluate biomechanical load for every component (static and dynamic load, force application, vibration and manual materials handling) for the whole body.
The EAWS meets these requirements. During its developments in particular the following design criteria were taken into account:
- The tool had to be accepted and considered exhaustive by:
- Applicator deviations – e.g. the gap between the analysis results of different applicators – had to be minimized, rendering the identification and measuring of technical actions, awkward postures and forces at maximum objective.
- The tool should have the capability to be used during the planning of the product/process as well as in the production process.
The main aims of the development of the EAWS system were:
- Compliance with labor legislation (national and international), e.g.:
- EU Machinery Directive (2006/42/EC, former 98/37/EU, 89/392/EEC)
- EU Framework Directive (89/391/EEC)
- Allow to document and evaluate the working conditions, taking into account the operator work load as it is described by the rules in force
- Ensuring ergonomic working conditions
- Developing an extension of the Automotive Assembly Worksheet (AAWS) for repetitive loads on the upper limbs in accordance with EN 1005-5 and the corresponding ISO standard 11228-3.
- Making this tool usable in any kind of company, from mass production to one of a kind production
- Developing a free tool without any kind of copyright
- Linking EAWS to MTM:
- MTM-2 : mass production systems
- UAS: batch production systems
MEK: one of a kind production systems
