Overview
The gate installer builds a machine on site. The
machine must be declared safe by the builder and
comply with the EU Machinery Directive. Parts for
the machine must be compliant and used as
directed by the manufacturer. Standards require
good design and good working practices. Finished
machines must be declared safe. Handover to a
responsible person includes documentation and
training to maintain the machine’s safety for users
& public. The latest DHF TS011 Code of Practice
can be found at www.dhfonline.org.uk
Force testing
EN12445 explains the method of testing the
impact forces of a gate. The crux is a graph of
acceptable forces from the point of impact.
Safety device applications
Safety devices such as sensitive edges and photo
beams are to stop, and if necessary, reverse the
gate movement in the “Risk Zone”. Applications
necessary for safety are primary devices. Other
applications that contribute to safety, but are
not necessary are supplementary devices. Some
devices are only rated for supplementary safety
use. Primary devices need to be Cat2 or Cat3 as
defined by EN954-1.
