Figure 28 on page C shows the location of the
SUPERTIRFOR™ safety pin.
To replace the pin, proceed as follows:
1) Remove the sheared SUPERTIRFOR™ pin using a pin
drift.
2) Clean the pin housings.
3) Line up the hole of the forward operating lever (item 1)
with that of the support yoke (item 2) (figure 28, page C).
4) Fully engage the new replacement SUPERTIRFOR™
pin (located in the clutch handle, item 22, figure 3,
page 7) into the housing by tapping lightly with the
hammer.
Before returning the machine to service, make sure that the
cause of the overload has been eliminated. If necessary, set
up a pulley block system (see figures 10 and 11, page A).
11. SUPERTIRFOR™ WIRE ROPE
(5 STRANDS MINIMUM)
To ensure safe use of the SUPERTIRFOR™ machines,
only SUPERTIRFOR™ wire ropes specially designed for
these machines should be used. The SUPERTIRFOR™
wire ropes have a red strand which is visible when new and
the TRACTEL logo at the location where the
SUPERTIRFOR™ wire rope loop is crimped.
For an installation requiring a very long SUPERTIRFOR™
wire rope (> 80 m), in particular when a pulley block system
is used, contact TRACTEL.
One end of the SUPERTIRFOR™ wire rope is equipped
with a safety hook mounted on a loop formed by the
SUPERTIRFOR™ wire rope, equipped with a lug and
crimped in a metal sleeve (see figure 40, page C). The
other end of the SUPERTIRFOR™ wire rope is welded and
ground (see figure 41, page C).
Safety is ensured by regularly verifying that your
SUPERTIRFOR™ wire rope is in good condition and that
your SUPERTIRFOR™ machine is in good condition.
You must therefore regularly monitor the condition of the
SUPERTIRFOR™ wire rope, clean it and lubricate it using
a rag moistened with oil or grease.
IMPORTANT
: Never use greases or oils containing
molybdenum disulfide or graphite additives.
The SUPERTIRFOR™ wire rope must be visually
inspected before each use for signs of possible damage
(see figure 42, page C).
If any visible deterioration is observed, have the
SUPERTIRFOR™ wire rope examined by a qualified
technician. Any SUPERTIRFOR™ wire rope for which wear
has reduced the nominal diameter by 10% must be
eliminated (measure diameter as indicated in figure 43,
page C).
IMPORTANT
: We recommend, especially for lifting
operations, that you ensure that the length of the
SUPERTIRFOR™ wire rope is greater than the travel
distance to be used. Provide at least one meter of
additional wire rope length to ensure that it goes past the
machine casing, on the anchoring side.
When lifting or lowering loads on very long wire ropes, you
should keep the load from turning to prevent un-stranding
of the SUPERTIRFOR™ wire rope.
Never allow a tensioned SUPERTIRFOR™ wire rope to rub
against an obstacle when lifting or lowering ; only pulleys
should be used. The diameter of the pulley groove must be
equal to at least 16 times the diameter of the cable (check
applicable regulations if necessary).
IMPORTANT
: Do not expose the SUPERTIRFOR™
wire rope to temperatures exceeding 100°C or to
mechanical or chemical agents which could damage the
wire rope.
Storage: see chapter 8.
12 MAINTENANCE OF MACHINES
12.1 SUPERTIRFOR™ MACHINES TU16H and
TU32H
IMPORTANT
: Never use oil or grease containing
molybdenum disulfide or a graphite additive. Servicing the
machine consists in cleaning and oiling the unit, and having
it periodically inspected (at least annually) by an approved
TRACTEL
® repair agent.
The inspection and maintenance sheet is located at the
end of this manual.
To clean the machine:
1) Disconnect the load from the machine, then disconnect
the machine from the hydraulic power pack.
2) Immerse it entirely in a solvent bath such as petroleum,
gasoline, white-spirit; do not use acetone, or
trichloroethylene, or any of their derivatives.
3) Shake it to remove any mud and other foreign matter.
Turn over the machine so that any dirt which it may
contain will come out through the lever opening. Allow it
to drip and dry.
4) The mechanism must then be generously lubricated by
pouring in oil (type SAE 90).
5) Release the mechanism first. The machine should be
free of any load. Operate the levers to facilitate
penetration of the oil in all the parts of the mechanism.
12.2 Hydraulic power pack and hoses
Servicing the hydraulic power pack consists in cleaning it
and having it inspected periodically (at least annually) by a
TRACTEL
® approved repair agent.
Fill with oil through the tank filler hole.
Check that the valves are clean at the hose ends which
should be equipped with dust covers. Each time you
connect the hoses to the rams, check that the valves are
clean (after each disconnection, be sure to fit the covers on
the valves).
In case of intensive use, you should change the hydraulic
oil every 6 months.
