Malfunctions - Tractel supertirfor Serie Traducción Del Manual Original

Malfunctions

The forward operating lever turns freely
on its pin without driving the mechanism.
Pumping: in forward operation, the
supertirfor™ wire rope or the machine
(depending on setup) moves up and
down by a few centimeters with no
progress.
Jerking: jerked maneuvers in reverse
operation.
Blocking: supertirfor™ wire rope blocked
in machine.
The flow regulator is not in the STOP
position and the rams do not operate.
The pressure gauge indicates a
maximum pressure and the rams do
not operate. For an installation with 2
or 4 machines, if one of the machines
exceeds the nominal load, the complete
installation shuts down.
The electric motor stops.
The electric motor starts with difficulty.

Diagnostics
The supertirfor™ safety pins* have
sheared under the effect of an overload.
(*: TU16H = 3 supertirfor™ safety pins,
TU32H = 1 supertirfor™ safety pin).
Insufficient oil in TU32H or TU16H
mechanism.
Same as above.
Damage to portion of supertirfor™ wire
rope located inside machine.
Electric motor turns backwards:
This could quickly damage the
hydraulic pump.
Insufficient hydraulic oil in tank. An
insufficient quantity of oil can very
quickly damage the hydraulic pump.
Nominal load reached.
Hoses incorrectly coupled to rams.
Motor overheating.
Connection or electrical power supply
problems.
Corrective actions
Replace the supertirfor™ pins as
instructed in chapter 10:
"Replacement of supertirfor™ safety
pins."
By pouring oil into the casing. If
necessary, operate the machine in the
reverse direction over a limited length
to facilitate lubrication of the internal
parts (see chapter 12: "Equipment
Maintenance").
When pumping occurs on a supertirfor™
machine in a multi-unit application, the
load must be balanced before performing
a maneuver on the supertirfor™ machine
which is pumping.
Same as above.
The maneuver must absolutely be
stopped. Secure the load by another
means satisfying the necessary safety
requirements and clear the supertirfor™
wire rope from the machine, disengaging
the machine once the load has been
removed. In an extreme case where this
may not be possible, return the machine
and its supertirfor™ wire rope to a
TRACTEL -approved repair agent.
®
Invert two of the three phases at the
power supply connector (see §4.3.1).
Fill with oil to the top level.
Decrease the load or, at best, balance
the load on all the machines.
Check all the couplings at the ball valves.
Allow the motor to cool before restarting
it. If the problem occurs again, the motor
must be better ventilated.
Check that the three electrical phases
are correctly connected and correctly
supplied at the worksite electrical meter.
