Checking the fork arms

DANGER
Risk of explosion!
If fork arms are used that do not cor-
respond to the explosion-protection
regulations, this can lead to spark for-
mation, resulting in explosions in the
surrounding atmosphere.
– Only use fork arms that are
approved for use in potentially
explosive areas according to the
nameplate of the truck.
– If the cladding is worn, do not
operate the truck in potentially
explosive areas.
The fork arms (1) are specially coated to
prevent sparks forming when coming into
contact with the load or the ground. The
cladding on the fork arms has six inspection
holes (2) on the top and the bottom. These
inspection holes allow the remaining cladding
thickness to be determined. The surface of
the back of the fork (4) is also clad with the
same material. There must be no cracks or
deformations visible on the fork arms in the
area around the fork bend (3). The coating
does not extend to the area around the fork
bends so that it is possible to check for cracks.
The Miretti job number is stamped into the fork
arm heads (5). If this number does not match
the data on the nameplate of the truck, the fork
arms must not be used until clearance has
been given by the authorised service centre.
– Perform a visual inspection of the fork arms
(1).
– Check the cladding (2, 4) for wear.
It must satisfy the minimum thickness of 1 mm.
– Check the fork bends (3) for cracks.
– Compare the Miretti job number on the
fork arm heads (5) with the data on the
nameplate of the truck.
– Ensure that only fork arms that comply with
explosion-protection regulations are fitted.
