ATEX - Spark Formation
Increased danger of ignition may emanate from
clashing of special material pairings. These are
non corrosion-resistant steel or cast iron against
aluminium, magnesium or pertinent alloys. This
applies especially in case of rust or surface rust.
When assembling the product and inserting fastening
components they must be clear of rust and debris of
any kind. Care must be taken to ensure the product
is handled in a suitable manner, is never thrown and
always placed onto the ground.
For Zone 1 and 2 applications, the height of the
PO RTA-GANTRY should NOT be adjusted using the
ratchet mechanism and/or geared wheel within the
said zone.
REID recommend the use of corrosion resistant tools
when assembling the PORTA-GANTRY system to
prevent the possibility of any sparks.
For ATEX Zone 1 use, stainless steel castor brackets
are fitted to reduce the possibility of a spark.
ATEX - Static Electricity
For Zone 2 applications static electricity has been
identified as potential for build up leading to an
incendive spark. Although the risk of such ignition is
unlikely the gantry must be earthed during assembly
and use. This can be achieved by attaching a 4mm
earthing lead to a convenient location on metallic
parts of both the Gantry and Trolley.
In Zone 1 applications, for added explosion protection,
the gantry is fitted with anti-static trolley rollers,
stainless steel fasteners and therefore does not
need to be earthed. However, the effectiveness of
the conductivity during operation can be affected
by a dirty tread or other environmental influences
and therefore must be checked by the operator
periodically.
ATEX - Inspection, Maintenance
& Repair
If using the gantry in explosive atmospheres, in
addition to the Regular Inspection/Maintenance
information found on page 6, these additional
instructions should be followed.
Inspections shall be instigated by the user prior to
each use if used in a potentially explosive atmosphere.
Inspections and maintenance shall be carried out at a
safe distance away from an explosive atmosphere.
Special attention should be given to dust deposits on
the structure, especially in areas where the profiles
come into contact, and should be wiped clean and
care taken not to apply materials that could create
electrostatic charging. Additionally the bearings in
the trolley rollers and castors should be checked to
ensure they rotate freely.
The structure is predominantly constructed from
aluminium which will not rust. However there are
steel components used throughout. These are
the fasteners, castors, master-link, trolley rollers,
A-frame height adjustment gearing system (if fitted)
and the height adjustment ratchet (if fitted). Where
there is sign of any rust deposits on the aluminium
structure it should be wiped clean as above and where
there is sign of rust on a steel component then that
component should be removed from use and the
structure not used until a replacement is fitted.
IRATA
PO RTA-GANTRYs are suitable for Rope Access and
have been tested to 15KN static load as per test
requirements of IRATA International Code of Practice
(ICOP).
LANGUAGE
It is essential for the safety of the user that if this
product is re-sold outside the original country of
destination the reseller shall provide instructions
for use, maintenance, for periodic examination and
for repair in the language of the country in which the
product is to be used.
