An Investigation into the Ergonomics of Open-Fronted Presses

Abstract

A group of open-fronted power presses was studied to determine what ergonomic improvements could be brought about in their design. The press dimensions, operating forces required on pedals and guards and positions adopted by seated operators were recorded and analysed.

From these data and the technical requirements of press operation, proposals for press dimensions to provide an adequate operator/machine relationship are given. These are supported by a discussion of the effects which the changed dimensions would bring about and by a small pilot experiment.

Long-term validation trials, both in the laboratory and the factory, are still in progress.
