Identified of malfunctions
(errors)
Cause
Elimination of malfunctions
1. After it is turned on, the
reeling machine does not
start working,
system pressure is 80 bar
or more.
a)
No electricity.
Put the plug in the socket.
b) Damaged or
improperly installed wire
rope
Properly install the wire rope on the drum
and the reeling machine. If the wire rope is
damaged, replace or remove the
damaged part. If the wire rope is installed
properly, it is possible to uncoil it by hand
when the thrust rollers are completely
loosened and the reeling function is
activated.
c) Thrust rollers are too
tight
Loosen the thrust rollers. After the reeling
machine is turned on, it should unreel the
wire rope and the pulley wheel should not
slide on the wire rope.
d) Safety brake is too
tight.
Completely loosen the thrust rollers on the
reeling machine. When the reeling
function is activated, the wire rope can be
uncoiled by hand. If the drum is resisting
too much, loosen the safety brake.
e) Damaged or blocked
hydraulic engine
Completely loosen the thrust rollers on the
reeling machine. The wire rope can be
unreeled by hand, the pulley wheel is not
spinning. Check for mechanical damage
of the reeling machine
–
blocked engine,
otherwise replace the hydraulic engine.
f) Failure of the
electrohydraulic valve
coil or valve
When the reeling machine is turned on,
there is no pressure in the hydraulic supply
pipe of the reeling machine's hydraulic
motor. Check the electrical connections
on the reeling machine's valve, coil and
valve.
g)
The speed control
valve is fully tightened
Adjust the unwinding speed according
to instructions
2.
After it is turned on,
the reeling machine
does not start working,
the system pressure is
less than 80 bar
a)Winch drive is not
activated
Turn on the winch drive.
b)
Damaged or worn
hydraulic engine
The hydraulic engine is too heavy so it
does not generate enough torque to
unreel the wire rope. Replace the
hydraulic engine.
c) An insufficient
quantity of oil
–
loud
pump
Add oil, check the filter in the tank.
3.
After it is turned on,
the reeling machine
unreels only ~ 5 m of
the wire rope and
then it stops
working.
When the unreeling
stops, check the
pressure in the system.
Then follow the
instruction under point
1 or 2.
