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.
NOTICE!
Use only in the intended atmosphere with a humidity of up to 100%, 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 Electric Chain Hoists, ultralow headroom
configuration
Type 29/06 EHS - with hand geared trolley
Type 29/06 EES - with electric trolley
With two hoisting gears which ensures low
oscillation during lifting and lowering.
Especially suitable to be combined with jib cranes.
The hoisting gears are driven by electric motor
and, the trolleys by hand via chains or by electric
motors.
Type 29/06 EES
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.

6 Installation
The assembly and installation depends on the local environment. The hoist must be suspended in a way that
it can position itself freely.
6.1 Trolley
For assembly on a beam a travel limit must be placed at either end of the track.
This must be attached so that any elastic limitation buffer or the trolley wheels are driven against them in
their end position when moving.
Generally, additional lifting gear (e.g. fork lift, lifting platforms) will be required for the assembly. These must
take the weight of the devices securely.
For hoists up to 6,3t capacity the trolley and the bottom block can be adjusted to different beam flange
widths.
Hoists from 8t capacity up are supplied adjusted to a fixed beam flange width in the factory. The adjustment
of the bottom block cannot be changed afterwards.
CAUTION!
The distance "X" between the wheel flanges of the trolley wheels must exceed the flange width "B" of the
beam by 2-3 mm (1-1,5 mm each side).

5.52.180.00.01.09
11
6.2 Devices with a load capacity of up to 6,3 t
6.2.1 Setting and checking the gauge
The trolley and the bottom block can be adjusted
to different beam flange widths.
Setting to the relevant beam flange width “B” is to
be made as follows:
Dimension "X" is set by placing washers (6)
from the outer to the inner side ("X" increases)
or from the inner to the outer side ("X"
decreases).
Washers must not be put away!
Tighten the hexagon nut (3) and safety nuts
(4) again.
Flange width “B” and the “X” setting must be
checked in all cases.
The same dimensions as used for changing
the track width must also be used for the
bottom block (10).
The load chain (11) must run in parallel
vertically. Do not put washers aside from the
bottom block.
"B" beam flange width
"X" gauge
Illustration 2
Place some washers from the outer side to the
inner side and vice versa to adjust the gauge -
they must be spread out evenly between the
rollers (12) and the hook tackle (13).
The two-part hook tackle must not be pulled
apart.
Tighten the hexagon nut (14) and safety nuts
(15) again.
Please make sure that the bottom block
does not jam at the beam flange when placed in
the upper hook position.

6.2.2 Installation on the beam

Pre-install the side plates (1) with load bars (2), washers (6), distance tubes (5), hexagon nuts (3) and
safety nuts (4) to adjusting value "X" as mentioned above.

Tighten the hexagon nuts (3) and safety nuts (4) and push the device onto the front face of the beam
flange.

Insert the threaded rod (7) through the corresponding holes and tighten the nuts (8, 9).

Tighten nut (8) first, then nut (9).
If this is not possible for lack of space or fixed end stops the trolley can also be installed on the beam from
below. Please proceed as follows:

Dismantle the hexagon nut (3) and safety nut (4) at the motor side.

The trolley halves must be separated until the trolley can be pushed over the track beam flange from
below.

Push the trolley together again until it reaches the correct wheel gauge "X".

Secure the washers (6) and distance tubes (5) by tightening the hexagon nuts (3) and the safety nuts (4).

Fasten the threaded rod as mentioned above.
With the devices in table 1 one of 4 wheels is driven by the travel drive. The axis of the driven wheel is set
slightly lower to ensure the required wheel pressure for traversing when the device is not under load. To
prevent the slack between load bolt (2) and the corresponding holes which are due to the manufacturing
process, having a negative impact on wheel pressure, proceed as follows:

12
5.52.180.00.01.09

Place a 2 mm thick sheet metal strip each under the 3 wheels which are not driven, loosen nuts (3,4) and
(9) slightly and put the device under load at the load hook until the rollers are under pressure.

Afterwards, tighten all nuts and safety nuts again.
6.3 Chain container installation
The chain container is supplied as a complete
unit. For the installation of the chain container, the
following must be observed:
Mount chain container (1) with screws (2) in
the position provided (3).
Let the load chain run smoothly into the chain
container (1).
The holding chain (4) which is already fixed to
the chain container must be fastened with
screw (6) at the position provided therefore at
the hoist (5) in such a way that the chain
container (1) hangs as horizontally as possible,
to achieve this, either shorten the holding chain
(4) or another chain link must be added to the
holding chain (4).
Re-check the fastening screws.
Check whether the load chain of the device
can enter the chain container freely by carrying
out a functional test without load.

5.52.180.00.01.09
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.
DANGER!
The use is not allowed:
for pulling loose of stuck loads, dragging of loads and inclined pulling.
in explosive atmosphere, except the unit is especially modified for it and marked by an indication label.
in reactor containment vessels.
to transport people.
The device is not suitable for use on stages and in studios.
Persons must not stand under a suspended load.

NOTICE!
For transport, some gear types are fitted with a plug screw. Replace the plug screw by a ventilation screw
(attached) before putting the unit into operation.
9.4 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.
9.5 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.

16
5.52.180.00.01.09
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.
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
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.

5.52.180.00.01.09
17
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.
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.
for hoists Type 4-8 with spur gear
NOTICE!
The weld seam of the chain must lie to the inner side and be in contact with the sprocket wheels.
for hoists Type AK 9-10 with planetary gear
NOTICE!
The weld seam of the chain must lie to the outer side and must not be in contact with the sprocket wheels.

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:

5.52.180.00.01.09
19
12.5.1 Slipping clutch
Illustration 13
12.5.2 Mechanical spring assembly
In case of overload the load must be lowered until it reaches the ground so that the
spring assembly can release. Only thereafter it is possible to repeat the lifting motion.
Illustration 14
Illustration 15
12.5.3 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 16
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
These conditions have to be written down in the test book.
The owner/user is responsible to make sure that these conditions are observed.
13.2 Periodic checks
Independently from the regulations of the individual countries, lifting devices must be checked at least yearly
by a qualified person or licensed qualified person regarding its functional safety.
13.2.1 Components to be checked
The following must be checked:

Dimensions of load chain, load hooks, pawls, bolts, ratchet wheels, brake linings.
