4 5.52.420.00.01.07
We refer to the prescribed equipment tests before initial start-up, before putting back into operation and the
regular periodic inspections.
In other countries any additional national regulations must be observed.
1.1 Indications to determine the used part of the theoretical usage life.
For motor driven units.
The equipment (rope hoists, chain hoists, winches as well as crane hoisting units) are classified in drive
groups (duty classification) according to their intended mode of operation, running times and load collectives
and dimensioned according to the requirements derived from these.
They are thus only designed for a limited period of use with regard to the overall dimensioning and
certification.
After the total period of use as elapsed, measures must be taken where parts are checked and exchanged
as per indication by the manufacturer. After that a new maximum usage period is determined. See also the
valued accident prevention regulations, “winches, lifting and pulling devices”.
NOTICE!
Commitment
A general overhaul may only be performed by HADEF or by a specialized company, authorized by HADEF.
2 Safety
2.1 Warning notice and symbols
Warnings and notice are shown as follows in these instructions:
DANGER! This means that there is a high risk that leads, if it is not avoided, to death or severe injury.
WARNING! This means that there is a risk that could lead, if it is not avoided, to death or severe injury.
CAUTION! This means that there is little risk that could lead, if it is not avoided, to slight injury or damage to the device or its
surrounding.
NOTICE! Gives advice for use and other useful information.

Danger from explosive area.
2.2 Duty of care of the owner
DANGER!
Failure to follow the instructions of this manual can lead to unpredictable hazards.
For any resulting damage or personal injury, HADEF assumes no liability.
The unit was designed and built following a risk analysis and careful selection of the harmonized standards
that are to be complied with, as well as other technical specifications. It therefore represents state-of-the-art
technology and provides the highest degree of safety.
Our delivery includes the hoist supplied beginning at its suspension and ending at the load hook and if
supplied with control, the control line/hose that leads to the hoist. Further operating material, tools, load
attaching devices as well as main energy supply lines must be assembled according to the valid rules and
regulations. For explosion-proof equipment, all these parts must be approved for use in area prone to
explosion, or they must be suitable for use in area prone to explosion. The owner is responsible for this.
However, in everyday operation this degree of safety can only be achieved if all measures required are
taken. It falls within the duty of care of the owner/user of the devices to plan these measures and to check
that they are being complied with.

5.52.420.00.01.07 5

Check brakes daily before commencing work.

5.52.420.00.01.07 7
The devices are not suitable for continuous operation. The duty cycles of the motors (see the technical
data chapter) as well as the remaining life time of the equipment in accordance with FEM group and
usage (see calculation of remaining safe working period) must be observed.
WARNING!
The following is not allowed:
to lift another load than the nominal safe working load
to manipulate the sliding clutch if units are equipped with
The use of elongated or damaged chains or wire ropes. Replace them immediately by new, original
parts.
Never loop the load chain around a load nor place or pull the chain over edges.
Never repair damaged load hooks (e.g. by hammering), but replace them by original hooks.
3 Transport and Storage
CAUTION!
Transport may only be done by qualified personnel. No liability for any damage resulting from improper
transport or improper storage.
3.1 Transport
The devices are checked and if so adequately packed before delivery.
Do not throw or drop the equipment.
Use adequate means of transport.

3.3 Storage
Store the equipment at a clean and dry place.
Protect the equipment against dirt, humidity and damage by an appropriate cover.
Protect hooks, wire ropes, chains and brakes against corrosion.
4 Description
4.1 Areas of application
The devices must be as far as possible installed in a covered room.
If they are used in the open, protect the units against the effects of weather such as rain, hail, snow, direct
sunshine, dust, etc. - we recommend to use a cover in parking position. If the device is set up in a
continuously humid environment with strong temperature fluctuations, the correct functionings are
endangered by the forming of condensation.
Ambient temperature -20°C up to +50°C. Power-operated units -20 up to +40°C. Humidity 100 % or less but
not under water
During longer periods of standstill, corrosion may reduce the function of the brake.
DANGER!
It is not permitted to use the unit in an area at risk from explosion!

4.2 Design
HADEF electrical chain hoists are equipped with a suspension eye for stationary use. The one and two chain
fall devices may optionally be equipped with a suspension hook.
All devices can also be supplied with monorail trolley with push travel, hand geared or electric drive.
Type 62/05 S, stationary
Type 62/05 R, with push travel trolley
Type 62/05 H, with gear travel trolley
Type 62/05 E, with electric travel trolley
Plan:
Chain falls
1/1 2/1
Operational limit switches for lifting and lowering
4.3 Functions
The lifting gear and motor-driven trolley are moved by pressing the buttons on the control switch. The spring-
pressure brake installed in the electric motor of the lifting gear prevents the independent lowering of the load
after the push button has been released.
By using a frequency converter, the speed is infinitely variable.
Hand geared trolleys are moved to the left or right by pulling one of the two stands of the endless hand
chain.
In combination with push travel trolleys the trolley is moved by pushing or pulling the load or, without load, by
pulling the load chain.
NOTICE!
The best protection against functional failures in case of extreme environmental impact is the regular use of
the equipment.
If the hoist is not used very often, we recommend to carry out a test run at least once a week and to switch
on the motor several times during this test run.
In our experience, this will prevent the brake from sticking.
4.4 Important components
Standard 3-phase current motor
Hoist gear
precision spur gear
All gears are fitted with vent screw.
Trolley gear motor
Combination of worm gear and motor.
Closed design - ventilation not necessary
Overload protection and emergency end limitation
Hoist with overload protection
Slipping clutch

5.52.420.00.01.07 9
The overload control is set in the factory according to the regulations; it is possible to adjust it later from
outside (see repair and maintenance section).
The slipping clutch prevents the lifting of a load that is too heavy by slipping through. In the standard design
with direct control the slipping clutch also takes on the function of an emergency final limit when the load is at
the highest and lowest position.
As an option the device can be supplied with an electronic overload control combined with a low voltage
control.
WARNING!
Never exceed the nominal load!
It is prohibited to use the emergency stop as operational limit switch.
NOTICE!
If it is necessary to approach the end stops during operation operating limit switches can be supplied (as an
option). These can, however, only be used with low voltage control.
Load chain
Special quality load chain. As the individual components of the chain drive are matched precisely to each
other, only original chains may be used.
Load hook
The load hook, which is made of highly stable forged steel, has a ball bearing. This facilitates attaching the
load and avoids the chain turning. The safety catch on the hook prevents the load from slipping out of the
hook unintentionally. The safety catch of the load hook must be able to move freely and be self-closing.
Chain container
The chain container is made of unbreakable plastic, plastic-coated fabric or sheet steel. It will supply different
sizes for different chain lengths.
Control
The electrical chain hoists are controlled as standard as follows:
By direct control
By low voltage control, optionally.
A remote control is available as an option.
Control switch
▫Control switch suitable for single hand use.
▫The control switch housing is made of shock- and fracture-proof plastic.
▫The control cable is fitted with a stress-relief rope (not applicable for radio control).
▫Plug-in connection for the control switch
Phase sequence- phase failure monitoring relay
All devices with low voltage control are equipped with a phase sequence and phase failure monitoring relay
as a standard. This will prevent incorrect phase sequence when connecting to the mains supply and will
switch off the device if phase failure occurs. In addition, all devices with low voltage control are equipped
with thermal sensors to protect the lifting motor and end switches for lifting/lowering as a standard.

CAUTION!
Run in of chain into the chain container for hoist with double lifting mechanism
For a correct run in of chain into both chain containers, the lowering operation must be carried out, without
load, at certain intervals, until both chain container are empty.
For motorized devices with operating limit switches "lowering"
Lower until the operating limit switch is released.
Non-observance can lead to device damages!
8 Operation
The following, important points must be observed when operating the equipment:
Read the safety instructions.
Never load the devices beyond their working load limit.
When changing the motor turning direction, allow the motor to come to a standstill first.
The prescribed maintenance intervals must be adhered to.
Observe the duty cycle, i.e. intermittent operation S4-40% ED (as per VDE 0530) means that in a period
of 10 minutes the motor can operate – no matter the height of the load – for 4 minutes. It is therefore
irrelevant whether the 4 minutes are continuous (i.e., in case of very high lifting heights) or are made in
intervals.
The lifting tackle or the load must be securely attached to the hook and be seated at the bottom of the
hook. The safety catch must always be closed.

9.3 Load chain
Before commissioning the load chain must be aligned and oiled.
For the first commissioning of motorized hoists, chain oil is supplied with the delivery.
Move safety note and fixing wire away from the chain.
9.4 Power operated hoists with chain container:
Due to the transport and / or installation of the hoist on the beam, the position of the load chain in
the chain container can change unfavorably.
WARNING!
It is mandatory before the first commissioning:
that the complete load chain without load with the utmost care from the chain
container is driven
i.e. when lowering, pay special attention to the load chain on the chain container side,
so that the load chain can run properly through the hoist without being twisted
only after the chain container is completely empty, the load chain without load, can
be returned to the chain container
during the running in of the load chain, lubricate it over its entire length
CAUTION!
Do not use grease for lubrication of load chain.
Without lubrication, manufacturer's warranty and/or liability will be void.
NOTICE!
Continuous, thorough lubrication will increase the life of the chain considerably.

16 5.52.420.00.01.07
9.5 Adjustment - limit switch for lifting
If desired the chain hoist can be fitted with a limit
switch for lifting GTES 51-67 or GTES 51-180.
It allows to adjust any switching point desired, for
example the limit positions of upper and lower
hook position. The slipping clutch incorporated in
the hoist serves as emergency stop.
If the chain hoist is supplied with switch included,
a switching point for upper and lower hook
position is preset.
The setting can be adjusted at the set screws 1
and 2 with a screw driver ø 4mm or 4mm
hexagon socket screw key. The table shows the
hook path for one turn of the set screw.

9.6 Setting of the switching points
set screw 1 "switching point 1 (lifting)"
The switching point can be set at any desired point
between upper and lower hook path limit. In order
to adjust move the load hook to the desired
position, which is possible by turning the set screw
1 to the left side. Afterwards turn the set screw 1 as
far to the right side until the switching contact
switches audible. 114 turns of the set screw mean
360° at the cam.
Drive two times into the desired hook position (1
creep speed, 2 main speed) and check the
switching point, adjust if necessary. The load
attaching device may not touch the housing and
thereby activate the slipping clutch.
set screw 2 "switching point 2 (lowering)"
The switching point can be set at any desired
point between upper and lower hook path limit. In
order to adjust move the load hook to the desired
position, which is possible by turning the set
screw 2 to the right side. Afterwards turn the set
screw 2 as far to the left side until the switching
contact switches audible. 114 turns of the set
screw mean 360° at the cam.
Drive two times into the desired hook position (1
creep speed, 2 main speed) and check the
switching point, adjust if necessary. The chain
attaching part may not touch the housing and
thereby activate the slipping clutch.
switching point 1 (lifting)
114 = 360°
switching point 2 (lowering)
114 = 360°
10 Safety check
Before putting into service initially or when putting back into service, it must be checked whether:
All fastening screws (if existent), socket pins, flap socket and safety devices are tightened and secured.
The oil levels in the gear boxes are sufficient.
All movements of the load comply with the symbols on the control switch.
The chains are correctly placed, oiled and in good condition.
11 Functional test

5.52.420.00.01.07 17
11.1 Checks before the initial start-up
Lifting gear
Load chains must not be twisted.
Lubricate the load chain with gear oil or suitable chain lubricant before first loading.
Trolley drive
The open-lying teeth of the trolley drive must be lubricated.
Hand gear for hand geared trolley
Ensure correct fit of the hand chain, it must not be twisted and must hang freely.
11.2 Functional test
Lifting gear
Check lifting and lowering functions, initially without a load. The buttons of the control switch are marked with
the symbols for lifting and lowering. The movement direction of the load (lifting or lowering) must correspond
with the push buttons (lifting or lowering). This is the factory setting.
If the device lowers when the “lift” button is operated and lifts when the “lower” button is operated, the two
phases of the net connection must be swapped.
The function of the end switch is to be checked initially by operating the end switch by hand. Then carefully
move to the end position. If required, adjust end switch.
Then check the brake function under load. After releasing the buttons of the control switch, the load must be
securely held.
Trolleys
Carefully move the trolley to the end positions and check the positions of the end stops.
NOTICE!
The limit switch function will only work if the movement direction of the load (lifting - lowering) corresponds
to the push buttons of the control switch.
12 Maintenance
12.1 General
All monitoring, servicing and maintenance operations are to ensure correct functioning of the equipment;
they must be effected with utmost care.
Only “qualified persons” may do this work.
Servicing and maintenance work must only be done when the hoist is not loaded.
Records must be kept of all test results and measures taken.
12.2 Monitoring
The monitoring and servicing intervals stated are valid for operation under normal conditions and single-shift
operation. In case of severe operating conditions (e.g. frequent operation with full load) or special
environmental conditions (e.g., heat, dust, etc.), the intervals must be shortened correspondingly
12.3 Replacing the load chain
CAUTION!
If there is any visible damage and when the conditions for replacement are reached (i.e. one or several
dimensions in the table have been reached, there is corrosion or elongation), the chain must be replaced.
When replacing the chain, also check the chain wheels.

18 5.52.420.00.01.07
Procedure:
Only insert new chains in an unloaded state and as the chains that are currently in the device – i.e. not
twisted.
Remove chain from its fastening at the end and attach a chain link which is open at the side.
A chain link which is open at the side, can
easily be produced by grinding out a small
piece. The opening must have the same
thickness as the chain link.
Illustration 10
Hang a new original chain (same size and oiled) in the side opened chain link and insert it.
Make sure the chain is not installed twisted.
Make sure the chain links are aligned in one direction.
Assemble the chain to the end fastening.
Running of the chain into the chain container:
Always run chains into the chain container by using the motor.
CAUTION!
Fill in the chain always motor driven.
Never run the chain in by hand, as there is a risk of knotting which can cause malfunctions and damage to
the device.

Illustration 15
12.5 Overload protection
If the hoist does not lift the permitted load, the overload protection must be adjusted. Adjustment may only be
done by a service company, authorised by the manufacturer!
DANGER!
The factory setting of the overload protection is secured by a seal. Any guarantee becomes invalid if this setting is
changed. Should maintenance be necessary, please contact a service company that is authorised by the
manufacturer.
Depending on the type of hoist, the following variants are possible:
12.5.1 Slipping clutch
Illustration 16
12.5.2 Electronic hoisting power limiter (as option, except serial AT)
Power consumption of the hoist motor is measured during lifting movement of a load
by an adjustable power measuring device (overload guard). The setting is made via a
separate relay for main and creep lifting speed. Power consumption of the motor is
load-dependent and increases with the load. If the set value is exceeded, the relay
responds immediately and switches the motor off via switching elements. After the
overload protection has been activated the LOWER button must be pressed first so
that the LIFT function can be activated again. Before lifting again the load must be
reduced to the nominal load!
Illustration 17
13 Inspection
13.1 General Overhaul for motor-driven units
The validated, national accident prevention regulations must be observed and the measures to reach "safe
working periods (S.W.P.)" according to FEM 9.755.
After the "theoretical working time D" has been elapsed, the owner/user must take motor driven devices out
of operation and effect a General Overhaul.
Further use of the equipment is only allowed after a licensed qualified person has proofed
that further use is possible without doubt
and
the conditions for further use have been determined
