9. WIRE ROPE

To guarantee the safe operation of JOCKEY
machines, it is essentiel to use them exclusively
with TIRFOR wire rope which has been specially
®
designed to meet the requirements of the JOCKEY
machine.
One end of the wire rope has a safety hook, fitted to a
thimble fixed by a metal ferrule (see Fig. 12). The other
end of the wire rope is fused and tapered (see Fig. 13).
A wire rope in good condition is a guarantee of safe-
ty, to the same extent as a machine in good condi-
tion. It is necessary to continously monitor the state of
wire rope, to clean and oil it with a rag soaked with
motor oil or grease. Grease or oil containing graphite
additives or molybdenum disulphide must not be used.
Visual examination of the wire rope
The wire rope should be examined daily to detect any
signs of wear (damage or broken wires : see examples in
Fig. 14).
In case of any apparent wear, have the wire rope chec-
ked by a competent person. Any wire rope with a reduc-
tion from the nominal diameter by more than 10 % should
be replaced. (see Fig. 15 for the correct method of mea-
suring the diameter of a wire rope).
IMPORTANT : It is recommended, specially for lif-
ting applications, to ensure that the length of wire rope is
greater than actually required. Allow an extra meter
approximately.
When lifting or lowering loads over long lengths of wire
rope, steps should be taken to stop the load from rotating
to prevent the wire rope from unlaying.
Never allow a tensioned wire rope to rub over sharp
edges. The wire rope must only be used with pulleys of
an appropriate diameter.
Never expose the wire rope to temperatures beyond 100
degrees C.
Never use wire rope that has been subject to damage
such as fire, corrosive chemicals or atmosphere, or expo-
sed to electric current.
Storage : See section 7.

10. MAINTENANCE INSTRUCTIONS

The machine should be inspected, cleaned and lubrica-
ted at regular intervals, at least annually, by an appro-
ved TRACTEL ® S.A.S. repairer.
Never use grease or oil containing graphite additives or
molybdenum disulphide .
To clean the machine , allow the machine to soak in a
bath of some proprietary cleansing fluid but not acetone
and derivatives or ethylene trichloride and derivatives.
Then shake the machine vigorously to loosen foreign
matter and turn it upside down to allow the dirt to come
™
out through the openings for the operating levers. Allow
the mechanism to drain and become dry.
After this treatment, ensure that the machine is well
™
lubricated by applying a quantity of oil (type SAE 90 -
120) onto the internal mechanism through the openings
for the operating levers. To carry out this procedure it is
best for the machine to be not under load and in the
released position. Alternatively operate the forward and
reverse operating levers to allow the lubricant to pene-
trate all parts of the mechanism.
N.B. : Excess lubrication cannot cause the machine or
wire rope to slip.
Any machine, the side cases of which show signs of
dents or damage, or of which the hook is damaged,
should be returned to an approved repairer.
11. WARNINGS AGAINST HAZARDOUS
OPERATIONS
The operation of JOCKEY
with the instructions of this manual, is a guarantee of
safety. Nevertheless, it is useful to draw the attention of
users to the following warnings :
- JOCKEY ™ machines described in this manual must not
be used for lifting people.
- Never attempt to motorise the models of JOCKEY
machines described in this manual.
- JOCKEY ™ machines must not be used beyond their
nominal capacity.
- JOCKEY ™ machines must not be used for applications
other than those for which they are intended.
- Never attempt to operate the rope release catch whil-
st the machine is under load.
- Always ensure that the operating levers and the rope
release catch are not obstructed.
- Never operate the forward and reverse operating
levers at the same time.
- Use only the operating handle supplied to operate the
JOCKEY ™ machine.
- It is forbidden to replace sheared pins by nonstandard
pins. Use only genuine TRACTEL
same model (Jockey
- Never anchor the machine other than by its appropriate
anchor point.
- Ensure that there are no obstructions around the machi-
7
machines, in accordance
™
shear pins of the
®
™ J5).
