Checking the condition of the antistatic belt
DANGER
Risk of fire and explosion pos
siblewithelectrostatic
discharging.
Safety warning: Tyres are n
ot electrically conduc-
tive.
The truck must always be
earthed using an antista-
tic belt.
The antistatic belt mu
st be in permanent contact
with the ground.
NOTE
Under certain circumstances, the truck may
become electrostatically charged.
•
The charging level depends on a number
of factors such as type of tyre, air humidity,
floor covering etc.
•
Excessive electrostatic charge is noticeable
when the electrostatic charge is discharged
to the ground via the body of a person who
touches the truck (electric shock) or when
a spark passes from the truck to an earthed
part (e.g. a metal shelf)
•
With standard types of tyre (b
lack pneuma-
tic or solid rubber tyres), th
ehighgraphite
content means that electro
static charging is
relatively rare.
•
However, if non-marking tyres (light-
coloured tyres) are used and the truck is
driven in an area with a sealed floor, this
electrostatic charge effect will frequently
occur
•
Non-scrubbing tyres are identified by the
safety information on the tyre wall.
For this scenario, an anti
static belt made
from non-conducting plas
tic is fitted to the
underside of the truck and
is connected to the
truck chassis.
Check that the antistatic belt is securely
seated on the frame floor and check for
wear.
Change the antistatic belt if it is damaged.
