Safety Alert - CUPLOK® Batten Bearer
IMPORTANT SAFETY ALERT - 25th May 2010
CUPLOK® STAIRCASE BATTEN BEARERS
Following a report that a person was injured on site when a CUPLOK® Batten Bearer hook failed on a CUPLOK® 4 leg staircase tower, Harsco Infrastructure has carried out 100% inspection
of batten bearers in its hire stock and has undertaken sample testing. Harsco
Infrastructure has not purchased the batten bearer items in question for several
years, but there is now evidence that a small number of bearers have been manufactured
non compliant to our specification and then received into stock.
It would appear that users on site may be "reworking" hooks if they become bent
out of line. As the non compliant bearers had cold formed hooks which are more
susceptible to fracture under this type of stress, the reworking can cause some
hooks to fracture in the radius of the bend. As the fault is in the manufacturing
process rather than design it is difficult to visually identify, in particular
when the bearers are in position within a staircase tower.
You must immediately identify any batten bearers in use and replace them with
mesh landing platforms 279417. Quarantine and not use any staircase transom units
(code 279394) and staircase batten bearers (code 279393). An alternative interim
“failsafe” measure may be employed until the bearers can be released from a tower
– shown in attached file.
Harsco Infrastructure has now decided that as the mesh landing platform design
provides productivity benefits and avoids any concerns with bearers, we will no
longer offer the batten bearer method. In future only mesh landing platforms for
4 leg staircase towers will be offered for hire or purchase.
Should you have any bearers that require inspection or replacement, please contact
your local Harsco Infrastructure branch for advice.
