EN 1398 is 12.5%, i.e. about 7°. For dierent types of loading equipment the maximum slope of
the leveller should be taken in accordance with Table 2.

OPERATIONAL MANUAL. ELECTROHYDRAULIC LEVELLER WITH SWING LIP SL SERIES88
DESCRIPTION AND WORK
The main components of the leveller are:
• Back support (frame). Designed for mounting the back part of the leveller to the pit;
• Lift part. Compensate for the difference in height of the truck body and the loading ramp;
• lip. Designed for overlapping and resting on the vehicle body;
• Support beam. Required for mounting the front part of the leveller to the pit. It is a
support element for fastening the hydraulic cylinders;
• Protective shutters. Used for closing of the gap between leveller and pit when the leveller
is in the raised position. Provides protection from crushing or entrapment oflimbs;
• Service support. Used to lock the rotary motion of the leveller during maintenance or
service work;
• Hydraulic unit. It provides hydraulic oil into the cylinders, thereby lifting the rotary part
of the leveller;
• Hydraulic cylinders. They are used for raising and lowering the rotary part of the leveller;
• Lip cylinder. It provides turning and folding of the lip.
2.4 DESIGN AND WORK
YATTENTION! During leveller positioning on to the body of the truck, you should make sure
that people or other objects are not within the working area of leveller. Only qualied workers
can manage the leveller. You should monitor carefully the movement of leveller during the
operation. Everyone who works with the leveller should be acquainted with its functions. The
operator must carefully read the operational manual.
During lifting of the loading/unloading platform by pressing the button for raising of the leveller,
the main power switch button must be turned on the‘1’position. Otherwise, the leveller will not
follow the height dierence of the truck body, and lead to machinery breakdown.
2.4.1 INTERFACING WITH VEHICLE
For safety reasons it is recommended to ensure the following things:
• there are no people or foreign objects at the entrance between the vehicle and the leveller;
• when you are driving up the drop side (tail lift) of the vehicle must be lowered;
• after parking, the vehicle (trailer) is fixed in place and cannot roll back or drive off
(the ignition key switched off, hand brake applied and wheel wedges installed).
2.4.2 LEVELLER POSITIONING IN THE VEHICLE BODY
YATTENTION! If leveller lip is equipped with additional unfolding segmentation, for narrower width
vehicles, the segments will be folded automatically. After the unsetting action of the leveller side
segments, they will return to the operating state. During the next operational cycle the central part
and the side segments will be rotated together, allowing use of the entire width of the lip.
To install the leveller in the vehicle body:
• turn the main switch to position ‘1’. During the leveller operation, loading or unloading
works it is prohibited to change the switch position;
• press the lip lift button. Hold it until the rotating part rises to the highest position and
the lip forms a single plane with the rotating part of the leveller;
• release the lift button. After this the rotating part begins to drop, and the lip lies on the
loading surface of the vehicle body;
• make sure the lip finally lies on the vehicle body surface and comes into it 80–100 mm
across its full-width.

OPERATIONAL MANUAL. ELECTROHYDRAULIC LEVELLER WITH SWING LIP SL SERIES 99
INTENDED USE
YATTENTION! During the loading/unloading process it is essential to control the lip position
within the vehicle body. If the lip has moved, it is necessary to stop work immediately. Lift
truck maximum travel speed should not exceed 5km/h.
2.4.3 LEVELLER UNSET
Оperational sequence after cargo handling works:
• press lip lift button. Immediately, the rotating part of the lip begins to rise, and at the
same time the lip folds. Hold the button until the lip folds fully;
• release the lift lip button. After this the rotating part begins to drop, and the platform
will unset;
• make sure the ramp is on the supports.
YATTENTION! If you hold the lip lift button for a long time, the rotating part reaches the top
position, and the lip starts to fold-out, i.e., platform switches into positioning mode.
3. INTENDED USE
3.1 OPERATING RESTRICTION
YATTENTION! Failure to comply with the rules of operation can lead to breakage of equipment
and injury of people!
• The leveller is not a lifting platform! Do not use it for lifting and lowering objects
or people. In the case of misuse or non-observance of current operating manual
instructions the product manufacturer is not responsible for damage to Customer’s
equipment and property and injury to the people;
• do not use the leveller combined with a vehicle lift tailgate;
• lift truck maximum travel speed should not exceed 5km/h.
• during operation of the leveller or the loading/unloading process, do not set the switch
to ‘0’ position;
• do not exceed the maximum angle of leveller lifting during the loading/unloading
process (7°);
• do not exceed the maximum load on the leveller (6 tons). It permits the use of loading
equipment (truck,electric pallet trucks, hydraulic hand truck, etc.), when the maximum
width of the wheels (seedimension X) isless than the width of the platform byat least
700mm (pic.3).

DECOMMISSIONING AND DISPOSAL
3.2 POSSIBLE DEFECTS
If failures occur, the risk of unsafe operation of the leveller increases. Operation of the defec-
tive leveller may cause injury to people and damage to objects. For troubleshooting refer to
organisations accredited by the ALUTECH group of companies.
3.3 OPERATION IN EXTREME CONDITIONS
In case you need to immediately halt the dock leveller, turn the red-yellow power switch into
the ‘0’ position. This will result in leveller movement blocking. Leveller movement blocking
happens in the following cases:
• when the switch is moved into ‘0’ position;
• when the mains power supply is cut.
After the mains power supply is restored it is necessary to press the platform lift button. The
dock leveller will return into freewheel mode.
3.4 MAINTENANCE AND CLEANING
Maintenance procedure is described in detail in the relevant section of the service book, which
you can download from the website alutech-group.com.
Dicult equipment handling operations call for professional knowledge. For your safety we
strongly recommend that you take out a contract for aftersales service with an organisation
accredited by ALUTECH GC.
The place under the platform needs to be kept clean. Debris accumulation prevents dock leveller
from functioning normally. Leveller pivot joints should be clean and free from dirt, stones and
other rubbish. Platform surface should be clean and dry. Don’t use aggressive substances or salt
to clean the platform. This may lead to corrosion.
4. DECOMMISSIONING AND DISPOSAL
If dock leveller is out of order it should be carefully disassembled and recycled. The disassembly
procedure is given below:
• before disassembly make sure the platform is in the inoperative position;
• deactivate supply voltage;
• drain any hydraulic oil, disassemble all hydraulic units and recycle them according to
current requirements and directions;
• after that fully disassemble the platform and take away all its parts. Appropriate
organisations may recommission dock leveller parts. If the platform is to be installed in
another place it is necessary to check operation safety according to new conditions of use;
• pass this manual and documentation on the control unit together with the platform to
the company dealing in disposal.
