NOTICE!
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.

The classification for the device can be found on the EX-type plate on the unit.
The device must only be used in the classification stated or in a lower classification.
2.6.2 Surface temperature of the devices
DANGER!
The temperature class mentioned on the EX-type plate on the unit must be observed, - make sure
that the max. surface temperature is even fallen short of.
DANGER!
The maximum surface temperature of the equipment must always be lower than the ignition
temperature of the gas/vapour/dust/air mixture. Equipment which has been classified in higher
temperature classes is, of course, also approved for use in applications with lower temperature
classes. As gas/air mixtures for T5 do not occur with normal use, and only very rarely occur for T6,
for specific gas/air mixtures such as carbon disulphide (IIC), our hoists are not rated for these
temperature classes and must not be used for these classes.

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.
Transport and means of transport must be suitable for the local conditions.
3.2 Safety device for transport
NOTICE!
Should a safety device for transport exist, please remove it before commissioning.
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.
DANGER!
Units that show corrosion must be taken out of service!
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.
Depending on the type of device, it is suitable for use in area at risk from explosion in the EX-classification
stated.
The EX-classification is mentioned on the EX-type plate on the hoist. The use of the unit is only allowed for
the EX-classification mentioned on the EX-type plate or lower EX classification.
4.2 Design
HADEF pneumatic chain hoists, with low
headroom design and pneumatic trolley Type
28/06APP, with hand-geared trolley Type
28/06APH and push travel trolley Type 28/06 APR
are monorail trolleys with integrated hoisting gear.
The hoisting gear is driven by compressed air
motors and, the trolleys by hand via chains or also
by compressed air motors.
Type 28/06APR - Table 1 - 0,5t

12 5.52.132.01.01.08
Type 28/06APP - Table 2-10t
Type 28/06APP - Table 2-15t
4.3 Functions
The lifting gear and motor-driven trolleys are moved by pressing the buttons on the control switch. The
spring-operated brake which is integrated in the lifting motor prevents the load from being lowered
automatically after releasing the control keys.
Hand geared trolleys are moved to the left or right by pulling one of the two stands of the endless hand
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

6 Installation
DANGER!
Assembly, disassembly and maintenance operations must only be carried out in an atmosphere not
prone to explosion!
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.

5.52.132.01.01.08 15
6.2 Adjusting the gauge
The trolley can be adjusted to various beam flange widths. Adjustment to the relevant beam flange width “B”
depends on the type and size and is to be made as follows:
There are distance tubes (5) and/or washers
(6) situated on the load bars (2) of the trolley.
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 (6) and rubber discs (depended on
type) leave a distance for the load hook. It is
important that the load hangs in the middle
under the beam so that the two side plates are
equally loaded.
The suspension eye (9) (if existent) for bigger
load bolts must still be swivelling after it has
been secured.
Tighten the hexagon nut (3) and safety nuts (4)
again.
Check correct flange width "B" and dimension
"X". Adjustment must be repeated if necessary.

6.3 Installation on the beam
1 Tighten the hexagon nut (3) and safety nuts (4).
2 Push on the trolley at the face of the beam flange.
3 If this is not possible, the trolley can also be mounted
on the beam from below.
4 Therefore, remove the hexagon nut (3) and the safety
nut (4) on the side without gear.
5 Pull apart the side plates (1) as far until it is possible to
push the trolley onto the beam flange from below.
Afterwards, push the trolley together to correct gauge.
6 Secure the washers (6) and distance tubes (5) by
tightening the hexagon nuts (3) and the safety nuts (4).

6.3.1 Bolt securing with collar
Securing the load bolts with set collars (1) and safety
screws (3).
In order to adjust the beam flange width dismantle
the safety screws (3) at one trolley side.
After adjustment of dimension "X" and installation on
the beam, install the safety screws (3) again and
secure them with a nut (4).
When pulling apart the side plates, the trolley drive
shaft will also be moved.
To do this, loosen the safety screws at the stern tube
bearing and secure them again after the side plates
have been pushed together.

CAUTION!
The distance “X” between the wheel flanges of the trolley wheels must be
for trolleys up to 3,2 t: 2-3 mm (1-1,5 mm each side) bigger and
for trolleys from 4 t up: 3-5 mm (1,5-2,5 mm each side) bigger than the flange width "B" of the beam
6.4 Pressure roller
6.4.1 Units with a load capacity of up to 6,3 t
These units are fitted with adjustable pressure
rollers (1).
After assembly on the beam, adjust the
pressure roller (1).
The air gap between beam and pressure roller
(1) must be approx. 1-2 mm.
Tighten the screw and nut (2).

6.5 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.

20 5.52.132.01.01.08
9.2.3 Maintenance unit
It is important that an automatic maintenance unit, consisting of oiler, filter ,water separator and air pressure
reducer is installed in the main air supply - if not assembled by the manufacturer this must be assembled by
the customer.
It serves for the necessary preparation of the operation air so that the pneumatic motor can work trouble-
free. Installation must be as close as possible to the motor; - in no cases should the distance to the motor
exceed 10 m.
Should higher pressure occur in the supply net, it will be reduced to the operating pressure of 6 bar by the
pressure reducing valve. The oiler enriches the air with oil. Setting of oil addition: approx. 2 drops of oil must
be added per minute.
NOTICE!
HADEF does not assume any responsibility for damage caused by non-observance of the instructions.
CAUTION!
Should the unit be assembled at the customer, the maintenance unit is supplied without oil.
Before putting the unit into operation, the main air supply line must be cleaned and the oiler of the
maintenance unit must be filled with oil. Should this not be done the unit may be severely damaged.
CAUTION!
The maintenance units are not approved for use with synthetic oil.
They must not be connected to compressed air systems which are supplied by compressors with synthetic
lubricants.
9.3 Gear
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.
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
