Safety Devices; Supertirfor™ Tu16H And Tu32H; Safety Device Limiting Overloads; Supertirfor™ Safety Pins - Tractel supertirfor TU16H Instructions D'emploi

For a hydraulic power pack with gasoline engine, make
sure that the storage location is properly ventilated.
The SUPERTIRFOR™ wire rope must be entirely removed
from the machine and stored on a reel.
Before winding the wire rope on its reel, inspect the wire
rope, clean it using a brush and lubricate it (see
recommendations in §11).
The hoses should be stored in the most linear position
possible, horizontally.

9. SAFETY DEVICES

9.1 SUPERTIRFOR™ TU16H and TU32H

9.1.1 Safety device limiting overloads

GB
9.1.1.1 SUPERTIRFOR™ safety pins
All the machine models are equipped with a system of
shear-type safety pins. In the event of an overload, one or
several pins (depending on model) located on the forward
operating lever will shear, making it impossible to continue
the movement. However, it is still possible to lower the load
or release the effort by actuating the reverse operating lever.

9.1.1.2 Hydraulic rams

The rams are equipped with a pressure relief valve, factory-
calibrated, to avoid overpressures in the ram in the forward
operating mode.
When one or several channels are used, if one of the
machines exceeds the nominal load, without rupture of the
SUPERTIRFOR™ safety pins, the complete installation
stops.
To correct this situation:
- decrease the load, or
- balance the load better on the various machines, or
- release (or lower) the load by maneuvering, using the
rams (or the extending handles after removing the rams)
the reverse operating levers of the SUPERTIRFOR™
machines.
IMPORTANT
an overload in reverse operation.

9.1.2 Clutch release safety device

The TU16H and TU32H models are equipped with a "two-
hand" clutch release device requiring a deliberate
maneuver to disengage the machine (see chapter 5
Releasing and engaging clutch).

9.2 Hydraulic power packs

9.2.1 "Deadman" device (only valid for
hydraulic power pack with electric motor)
A "deadman" device is provided with the hydraulic power
packs. Operation of the device consists in shutting down
the electric motor of the hydraulic power pack when the
pushbutton actuating the hydraulic power pack is released.

9.2.2 Safety valve

The hydraulic power packs are equipped with a pressure
release valve (overpressure safety), factory-calibrated, to
avoid overpressures in the hydraulic power pack. If the
valve opens, it is no longer possible to lift a load. The load
: The valve will not allow you to detect
remains stationary. However, the machine can still be
maneuvered to lower (or release) the load by maneuvering,
using the ram (or the extending handle, after removing the
ram), the reverse operating lever.
IMPORTANT
: The valve will not allow you to detect
an overload in reverse operation.
9.2.3 Thermal protection probe (only valid for
hydraulic power pack with electric motor)
The electric motor of the hydraulic power pack is equipped
with a thermal probe. If the motor overheats, the motor is
shut down. Allow the motor to cool before restarting it.
If shutdown of the motor occurs again, better ventilation for
the motor must be provided.
10. REPLACEMENT OF SUPERTIRFOR™
SAFETY PINS
IMPORTANT
: It is prohibited to replace sheared
pins with anything other than genuine SUPERTIRFOR™
pins of the same model.
NOTE
: We recommend that you keep a
sufficient quantity of spare SUPERTIRFOR™ pins to avoid
any extended work stoppage when using the machine.

10.1 Standard precautions

Before replacing pins, you must first:
1) Ensure that there is no load on the machine.
2) Shut down the hydraulic power pack and disconnect it
from its power source.
3) Remove the ram from the SUPERTIRFOR™ machine.

10.2 Equipment required

Designation For TU16H
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.
