2.5 Technical Bulletin about vertical axes from the German
Trade Association
This Technical Bulletin aims to summarize the knowledge and experience
available with regard to improved safety at work for activities at or close to
vertical axes. This is realized by applying practical control measures to prevent
axes falling due to the force of gravity. The Technical Bulletin is based on the
experience of manufacturers of industrial robots, including linear robots and
handling systems, by drive and control systems manufacturers and by the
users of those systems, particularly in automobile production and the German
Trade Association.
The Technical Bulletin shows typical hazardous situations with regard to
vertical axes and gives suitable solutions for risk reduction by applying
appropriate control measures. Other measures against preventing axes falling,
which are not considered in this bulletin, remain unaffected. Consideration is
given to vertical axes driven by electric motors as well as inclined axes with
motor-integrated brake or external brake which could fall due to gravity in case
of a brake failure.
