4- Feeble motor rotation
with “groaning”
• Defective power supply.
• Major drop in voltage.
• Electromagnetic brake jammed
shut.
• Lack of torque on start-up
(defective permanent
condenser or motor winding coil
burnout).
• Defective reduction gear or
brake.
• Overload.
• Check the power supply voltage.
• Return the equipment to a
TRACTEL
®
approved repair service
if the power supply voltage or
surges are not the cause.
• Reduce or hoist the load.
5- Cable cannot be inserted • Overly thick cable.
• Defective cable tip.
• Cable deformation.
• For a three phase model,
reversed controls.
• Worn interior guiding parts.
• Check the diameter. Replace with a
cable of the correct diameter.
• If necessary, re-weld the end of the
cable using a blowtorch. Grind and
round off.
• Discard the deformed part. Cut, re-
weld and grind the cut end.
• Press the “Down” button. If the
cable engages normally, press the
“Up” button to release it and reverse
the phases on the connector set up
for this purpose.
• Should none of the above causes
be revealed, send the Minifor to a
TRACTEL
®
approved repair service.
6- The cable slides or slips
on the uphill
• Overly thin cable.
• Cable wear more than 10% of
the nominal diameter.
• Heavy wear to the tightening
system.
• Check the diameter of the cable as
shown in the instructions. If the
cable should prove to be non-
compliant or worn, discard it and
replace with a new one.
• If the cable is normal, send the
Minifor to a TRACTEL
®
approved
repair service.
7- Load descent is no
longer slowed: the cable
slides despite the motor
being stopped
• Brake maladjusted.
• Worn brake shoes.
• Brake shoes tainted by oil or
grease.
• Overload.
• Adjust the air gap.
• Return the equipment to a
TRACTEL
®
approved repair service.
8- The motor cuts out
during a manoeuvre
• After intense usage the motor is
too hot and the heat probe
triggers .
• Wait for cooling.
