10.2 Equipment required

Designation
13 mm wrench
Hub puller
Pin drift
Hammer

10.3 TU16H

Figure 20 on page B shows the location of the supertirfor™ safety pins.
To replace the pins, proceed as follows:
1. Unscrew the hex head screw (figure 19, item 1, page B) using the
13 mm wrench and remove the washer.
2. Remove the forward operating lever from its pin; this will require use
of a hub puller.
3. Remove the sheared supertirfor™ pins using a pin drift.
4. Clean the pin housing.
5. Reinstall the forward operating lever on its swivel pin by lining up the
half-housing of the pin with those of the lever (see figure 20, page B).
6. Fully engage the new replacement supertirfor™ pins (located in the
forward operation ram bearing, item 22, figure 2, page 7) into their
housing by tapping lightly with the hammer.
7. Fit the washer and tighten the screw using the 13 mm wrench.

10.4 TU32H

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.
CAUTION: When using supertirfor™ machines with extensive steel rope
length (> than 80 metres), or with a haul system, or with a retracting
pulley, TRACTEL recommends that you use specific steel ropes:
®
- for the supertirfor™ TU32A: supertirfor™ HD steel rope - code 12311,
- for the supertirfor™ TU16A: supertirfor™ HD steel rope - code 8921.
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: "Shutdown and storage".

12. Equipment Maintenance

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
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.
