1 - Conditions for use
All users must read the set-up instructions carefully before using the product for the first time.
These instructions should enable the user to familiarise themselves with the winch and use it to its
full capacity. The set-up instructions contain important information about how to use the winch
safely and correctly. Compliance with these instructions helps to avoid danger, reduce repair costs,
reduce stoppage time and improve the reliability and service life of the winch. The instruction
manual must always be available in the place where the winch is being used. In addition to the
set-up instructions and regulations concerning the prevention of accidents, the work safety and
professional regulations in force in each country must also be respected.
This equipment is governed by European regulations and more specifically Directive 2006/42/EC
on machinery, Directive CEM 2014/30/UE, BT 2014/35/UE and RED 2014/53/UE as well as the EN
14492/1 standard.
These winches are designed to move loads using a suitable steel rope. They have been designed to
perform lifting and pulling operations within the defined load capacity limit and with safety factor 5
(static against sudden failure).
For use in lifting, the European regulation makes certain equipment obligatory, such as a limit
switch system and, for loads of 1,000 kg or more, a load limiter.
The operator must check the presence of this equipment (available as an option from the
manufacturer) before using the product for lifting purposes.
The capacity indicated on the winch corresponds to the maximum capacity of use (MCU); in no
event should this capacity be exceeded.
THIS WINCH MUST NOT,UNDER ANY CIRCUMSTANCES,BE USED TO LIFT PEOPLE.
Do not begin moving the load until you have attached it correctly and checked that all
personnel are outside the danger zone.

Before use, the operator must always check that the machine, rope, hook, markings and
moorings are in good working order.
The operator must check that the load is attached in such a way that the winch, the rope and
the load place neither the operator nor any other person in danger.
The winches can be used at ambient temperatures ranging from -10°C to +50°C. Please
consult the manufacturer in the event of extreme conditions of use.
Important: In the event of an ambient temperature below 0°C, the brake must be tested to ensure
that there are no operating faults resulting from the freezing conditions.
Use of winches requires strict compliance with the accident prevention and safety measures in
force in the country.
The data concerning the resistance of the steel rope and its fastenings to heat must be available
on request from the manufacturer and must be respected.

To determine the group for a lifting machine, winch or hoist, three essential parameters must be
considered:
The maximum load to be lifted
Including the weight of the rope and any lifting accessories present (hook etc.), except if they
have a total weight less than or equal to 5% of the load to be lifted.
The usage rate
Indicates the extent to which the lifting machine is used at maximum load or with a reduced load.
There are four different usage rates:

Translation of the original instructions manual 8UK Reproduction prohibited
Light
Lifting machines rarely subject to maximum load and
regularly used for very light loads.
k ≤ 0,5
Medium
Lifting machines quite often subject to maximum load
and regularly used for light loads.
0,5 < k ≤ 0,63
Heavy
Lifting machines often subject to maximum load and
regularly used for medium loads.
0,63 < k ≤ 0,8
Very
heavy
Lifting machines regularly subject to loads close to the
maximum load.
0,8 < k ≤ 1
For an exact classification, it is preferable to calculate the average cubic value using the following
formula:
where:
ß= payload or partial load
rated capacity
t= operating time with payload or partial load + dead load
total operating time
Y= dead load
maximum capacity
tΔ= operating time with dead load only

8 - Installation and set-up
8.1 Installation
The service life of a winch depends on its installation and set-up.
It is essential that you read this manual carefully before installing, using and servicing your
machine.
Any use which contravenes our instructions may create a hazard. In this case, the
manufacturer cannot accept any liability.
Do not use this machine before having read and understood the instruction manual in its
entirety
Always keep the manual close to the machine, available to the operator and the
maintenance officer
Comply and ensure compliance with the safety rules
Connect to the power supply (see 8.3 Power supply)
Check the rope and hook
Ensure you are ready to press the emergency stop button at all times, with no load attached,
then check that the movement of the hook corresponds to the direction of the arrows indicated
on the control unit.
Check that the brake works: with a nominal load attached, lift the load and lower it again or, in
the case of pulling, pull this load.
Check that the limit switch works.
The winch has been subjected to dynamic and static tests in the factory (cf. Test record).
8.2 Place of installation
These winches must be installed and bolted to a flat, solid and secure surface capable of
bearing the loads to which it will be subjected. An unsuitable installation site may lead to
serious accidents.
To assess the suitability of the place of installation and its resistance to loads, you must take
into account any possible overloading, the weight of the winch itself and the weight of the
options and/or accessories fitted to it, including all dynamic forces. The winch user is
responsible for determining the place of installation. If in doubt with regard to the suitability of
a place of installation, contact a civil engineer or a statics specialist.

8.4 –Power supply
Before undertaking any operation on the electrical unit, check that the power supply to the
machine is off.
A disconnecting switch must be placed no more than 10 metres from the place of use.
Very important: the winch will only provide full power if the motor is supplied via a cable
section which is perfectly suited to this use.
Provide protection for individuals in front of the electrical unit.
8.4.1 –Electrical connections
The power supply cable, the protective fuses and the main disconnecting switch (see
wiring diagram) must be provided by the customer.
Check that the supply network complies with the machine.
Check the type of current; there must not be more than about 5% deviation from the
rated voltage
Neutralise electrical sources
Check that the main power supply switch on the winch is in the off position.
Do not connect the power supply cable to the machine using connection terminals (split
fittings etc.)
Do not use a cable with a smaller section to supply power to the machine. Power supply
via a generator is possible:
-Minimum power of 3.75 kVA according to the models 250 and 400 kg.
-Minimum power of 5,5 kVA according to the models 1000 kg.
Never "shunt" the disconnecting switches, electrical switches, prevention or limitation
equipment.
Never block, adjust or remove switches or end stops in order to go beyond the levels that
they allow.
A disconnecting switch must be placed no more than 10 metres from the place of use.

using about 0.5 m of power supply cable.
Check that the winch works (direction of rotation)
Do not change the direction labels in the control unit or in the winch's internal wiring.
8.5 –Work rope
Important: the direction of rotation of the drum depends on the way in which the machine is
connected (order of the three-phase current phases)
Reminder: check the maximum capacity of the winch
Very important:
The safety regulations require that 2 to 3 coils of rope always be left on the drum.
To comply with the legislation, the rope diameter must not exceed the recommended
diameter.
If the rope and the hook used were not supplied with the machine by the manufacturer, check
that they guarantee a level of safety corresponding to table § 6.5.
When the winch is supplied with the rope wound on, it has not been tautened during assembly.

© 2011 by Huchez Treuils S.A.S.
Translation of the original instructions manual11UK Reproduction prohibited
The user must tauten the rope using a minimum force of 1% of the operating load of the
winch.
The service life of the steel ropes used on the winch depends on a number of factors, including
the form of the work cycles (lifting height, lifting speed, number and type of deviations, etc.)
and the operating mode (number of coil layers, distribution of the work cycles over the length
of the steel rope, etc.). The service life of steel ropes is therefore subject to considerable
variation depending on these factors.
Please remember that rope must be replaced with equipment which meets the same
specifications as the original rope.
This replacement must be recorded in the maintenance booklet.
IMPORTANT: even if the rope was supplied with the winch, it was not tautened during
assembly. The user must tauten it using a minimum force of 1% of its breaking load.
Measuring the rope diameter using sleeve callipers:
Correct measurement Incorrect measurement
Handling steel ropes
Always use suitable protective gloves when handling steel ropes
Never use a rope with faults such as:
An unacceptable number of broken strands
Basket distortions
Broken bird-caging
Flattening
Constrictions
Strand extrusions
Broken rope cores
Slack strands
Bends or loops
Always check the level of wear of the rope before use
Never use steel ropes as loops
Never expose steel ropes to angular or sharp edges

Fastening the rope
Models PRIMO INOX 250/400/1000
Refer to the photos below.
If necessary, remove the limit switch
Slacken the screws
Insert the end of the rope between the drum flange and the cable clamp
Tighten the screws
Check that the rope is securely clamped
Reassemble the limit switch
The rope should never form a loop.
Important: the direction of rotation of the drum depends on how the machine is connected.
Winding the rope on the drum
To do this, tauten the rope and wind it with joined strands onto the drum.
Very important : The safety regulations require that 3 coils of rope always be left on the drum. If the
rope and the hook used were not supplied with the machine by the manufacturer, check that they
guarantee a level of safety corresponding to table § 5.
Start to wind the rope forming a spiral to the right. In order to facilitate this operation, some drums
are provided with a heel attached to one of the flanges, which "fills" the space between the first turn
and the flange.
The first layer must be wound in a compact manner and under tension. Take a mallet or a block of
wood and knock the turns against one another; not too hard to prevent the strands from overlapping
one another, but tightly enough to prevent the rope from moving on the drum. If the first layer is
wound too loose, the next layer will form a space in the first layer that will result in an open area. If
the first layer is too tight, the subsequent layers will not have enough space between turns.
In any case, the first layer and all the other layers must be wound onto the drum with enough pre-
tension (5-10 % of the MWL of the rope). If the rope is wound without any tension, it will suffer from
crushing and premature flattening caused by the loaded upper layers.
Even if the first layer is wound correctly during installation, it will expand a little while in service.
When the first layer expands (loss of pre-tension) the initial procedure MUST be performed at regular
intervals.
Otherwise, the "hard" turns will severely crush the base layers.
Whatever you do, DO NOT pass the rope through a clamping mechanism. For example, two blocks of
wood screwed together. THIS WILL CAUSE IRREPARABLE DAMAGE TO THE ROPE!
It is important to respect the indication below; if the rope start on the winch is at the bottom,
respect the same principle. Failure to respect this precaution will damage your rope irretrievably and it
will become extremely dangerous.

9 –Servicing and maintenance
Respect the following instructions, in particular if your winch is used in a large number of different
locations or in a particularly dirty and damp environment:
Remove the bulk of the dirt from the winch.
Always store the winch in a dry, clean place.
9.1 Before starting up
Check:
The electrical connections are in good working order.
The rope is correctly fastened to the drum.
The exterior appearance of the winch.
9.2 When using for the first time
At the start of the installation process, it is recommended that you respect a running-in
period of thirty hours at ¾ of the load. The nominal capacity will be obtained after this
running-in period.
9.3 Periodic servicing
See also chapter 5: Obligatory regulatory checks by the user
Every 50 hours, check the lubrication.
Every 100 hours, change the grease.
The reducer is lubricated using RENOLIT CXI 2 (fabricant : FUCHS).
Very important:
In the event of a change in the type of grease, contact our after-sales service.
Winches
Remove the bulk of the dirt from the winch.
Always store the winch in a dry place
Ropes
The ropes must be cleaned and greased regularly using a special grease which penetrates to the
rope core.
Only use appropriate and harmless cleaning products for all the components of the rope, including
the core.
If lubrication is impossible for usage-related reasons, the service life of the rope will be reduced
considerably and increased monitoring of the rope will therefore be necessary.
The ropes must be checked visually every day.
Servicing and maintenance operations on the winch and rope must be carried
out without any load on the winch.
Hooks
Check the hook and its safety latch
If the rope and hook are not supplied by the manufacturer, check that the parts used guarantee a
level of safety corresponding to table §4.4.
Check the fastening points of the reeving on a regular basis.
Brake
Models PRIMO INOX 250/400/1000
(the brake is located inside the motor)

. Operating principle:
On starting the motor, the internal magnetic field opens the brake by lifting the conical plate from
the friction surface at the bottom of the motor.
On stopping the motor, the magnetic field disappears. The central spring closes the brake again by
bringing the conical panel back into contact with the motor's rear flange.
10 –Taking out of use
If the equipment is in a state of disrepair likely to give rise to risks, the user is obliged to
