WARNING : Having wire rope which is in
good condition is a guarantee of safety, just
as much as having equipment which is in
good condition.
It is therefore necessary to continuously monitor
the condition of the wire rope and to clean and
grease it with a cloth impregnated with oil or
grease.
Greases and oils containing molybdenum bisul-
phide or additives containing graphite should be
avoided.
Visual inspection of the wire ropes:
The wire ropes should be examined on a daily
basis when the equipment is in use in order to
detect any signs of damage (deformation,
broken wires: see example fig. above).
If there is any obvious damage, the wire rope
should be checked by a competent person. Any
wire rope whose nominal diameter has been
reduced by 10 % as a result of wear must be
d
removed (measure as shown in fig.).
IMPORTANT : A tensioned wire rope must
never be allowed to rub on an obstacle. Wire
ropes must never be exposed to temperatures
above 100°, or to attack from mechanical or
chemical agents.
It is vital to check that the length of the wire
ropes is greater than the lifting distance. Allow
for at least a metre of wire rope to remain on
the winding reeler.
Storage: see section 7.

11. MAINTENANCE :

The tirfor ® machine and Blocstop™ device
must be inspected, cleaned and lubricated at
regular intervals, at least annually by an appro-
ved repairer.
To clean the devices, immerse them in a bath of
solvent such as oil, petrol or white spirit (with the
exception of acetone and its derivatives, and tri-
chlorethylene and its derivatives) then shake
them to remove sludge and any other foreign
matter. Tip up the device so that the dirty liquid
comes out of the lever apertures. Drain and
leave to dry. It is then essential to lubricate the
mechanism thoroughly by pouring oil (type
SAE 90 or 120) into the holes in the housings as
well as in the special aperture (oiler) on the
TM
TU 6PM and on the TU
pouring the oil in, release the device (which
must not be sup- porting a load), and operate
the levers to help the oil reach all parts of the
mechanism.
N.B.: The device can never be overlubricated.
Any device whose housing shows traces of
impact or deformation, or whose hook (model
TM TM
TU 6PM and TU
be returned to a TRACTEL group approved
repairer.
