EC Machinery Working Group meets

From our friends at MachineBuilding​.net.

It is now more than a year since the new Machinery Directive (2006/​42/​EC) came into force, but the sit­u­a­tion is still fairly fluid in some respects. The EC Machinery Working Group meets reg­u­larly to dis­cuss mat­ters relat­ing to the Directive and cor­re­spond­ing stan­dards; the last meet­ing took place on 21/​22 December. According to the Stakeholder Report pub­lished in the UK by BIS (the Department for Business, Innovation & Skills), a num­ber of issues were dis­cussed, which demon­strates that the Machinery Directive is not as ‘black and white’ as might be expected.

For exam­ple, EN 12635 (Industrial, com­mer­cial and garage doors and gates — Installation and use) is cur­rently har­monised to the Machinery Directive, but the UK has raised a for­mal objec­tion against this stan­dard, as it would appear that there is scope for improve­ment. Other top­ics under dis­cus­sion ranged from vari­able reach trucks, tail lifts and loader cranes, to stave split­ters, dynamome­ters and ‘grey’ imports of machinery.

If you would like more infor­ma­tion, copies of the cur­rent and pre­vi­ous Stakeholder Reports are avail­able in PDF for­mat from the UK Department of Business Information & Skills (BIS) web site.

Retained fastenings for fixed guards

If you are build­ing machin­ery that will be CE marked or is sub­ject to the EU Machinery Directive, you need to read this arti­cle at MachineBuilding​.net

This arti­cle reviews some of the retained fas­ten­ings that are avail­able for use on fixed machine guards, as required by the new Machinery Directive 2006/​42/​EC and the guard­ing stan­dard EN 953:1997+A1:2009.

One of the changes in the new Machinery Directive is that the Essential Health and Safety Requirements (1.4.2.1, fixed guards), states: “fix­ing sys­tems must remain attached to the guards or machin­ery when the guards are removed.” This new require­ment has also been added to the amended EN 953.

Various types of retained fas­ten­ing — such as cap­tive screws and quarter-​​turn fas­ten­ers — are avail­able, but machine builders need to spec­ify these with care if they are to find the opti­mum com­bi­na­tion of pur­chase cost, instal­la­tion cost and ease of use. Also bear in mind the require­ment that “fixed guards must be fixed by sys­tems that can be opened or removed only with tools.” What fol­lows is a sum­mary of some of the prod­ucts and sup­pli­ers oper­at­ing in this field.
