Ixtur LI-120
General Product Information
Automatic Lifting Magnet LI-120 manufactured by Ixtur, is electrically controlled lifting equipment, which
creates magnetic holding force with a permanent-magnet. LI-120 is a flexible and user-friendly device for
professional use. LI-120 can be utilized either manually with operation buttons or automatically with built-in
load-sensing system.
Energy efficiency. Automatic Lifting Magnet LI-120 has bi-stable operational structure, which means that the
device does not consume energy while maintaining the magnet's ON (attached) or OFF (released) -state.
Because of bi-stable structure the design solutions have low energy consumption. The switching between
states is controlled with a short electrical pulse. This increases the number of lifts to over one thousand with
one complete battery charge.
Serviceability. Automatic Lifting Magnet LI-120 has low energy consumption which has removed the
requirement for an external power source. This allows a compactly integrated package with a chargeable
battery. Low energy consumption extends operating time, which results to long and efficient working without
interruptions.
Safety. Automatic Lifting Magnet LI-120 produces a magnetic holding force beneath it's magnetic lifting
surface only with loads made of ferromagnetic materials. Automatic Lifter LI-120 activates the magnetic lifting
surface only with a sufficiently small air gap. Automatic Lifter LI-120 leaves the magnet in its latest state
('attach' or 'release') in case the power is lost. The battery status can be checked from the device and low
capacity is indicated by blinking lights. Automatic operation mode of Automatic Lifter LI-120 allows the
operator to stay clear of the load during lifting without the need to go to the lifting area.
Purpose of the Product
Automatic Lifting Magnet LI-120 is a portable and detachable lifting equipment, which is intended for
temporary lifting and transportation of loads made of ferromagnetic materials.
Lifting Magnet LI-120 is intended for such lifting operations where the use of other mechanical hoist systems
would be slow or when the accessibility of either hoist system or load would be poor and would require the
operator to go to the lifting area during the lift.
Lifting Magnet LI-120 is not intended for permanent attachment to load items.
In case Lifting Magnet LI-120 is used as a component, in order to integrate one or several Lifting
Magnet LI-120 devices to larger lifting system, or to connect the devices to one another, permanently
or temporarily, in all such cases it is the responsibility of the designer, the manufacturer and the
operator of the device or the system to ensure that local and national safety regulations and general
safety policies are met.

Automatic Lifting Magnet LI-120 features
Holding Force and Lifting Capacity
Holding force and rated lifting capacity of Automatic Lifting Magnet LI-120 can only be applied to such lifting
situations where the forces are perpendicular to the magnet's lifting surface. Material properties and thickness
of the load also affect the holding force, as well as any non-magnetic material that separates the magnet's
lifting surface from the surface of the load, for example air. Surfaces must be clean and the air gap zero to
achieve maximum holding force. The load surface must be flat and it must occupy the lifting surface of the
device completely.
Maximum holding force and lifting capacity of Automatic Lifting Magnet LI-120 are rated with steel EN S235,
with minimum material thickness of 12 mm.
Lifting capacity is proportional to the material thickness, which is presented later in this user manual in chapter
'Material Thickness'.
Lifting capacity is proportional to the air gap, which is presented later in this user manual in chapter 'Air Gap
and Surface Quality'.
Read carefully the characteristics related to the magnet's lifting capacity before deployment of
Automatic Lifting Magnet LI-120
Lifting capacity of the device must not be exceeded
The device should be centered with the load to minimize inclination and to ensure safe lift
An inclined load causes a twisting force on the device which reduces the lifting capacity
An inclined load may slide which could cause the load to drop
The forces caused by acceleration must be considered during lifting. For example, sudden
raising or lowering cause stronger forces than slow and smooth moves.
Material Properties
Magnetic characteristics of the material being lifted affect the magnet's holding force. Primary components of
holding force are the intensity of magnetic field and the magnetic characteristics that define how well the lifted
material conducts the magnetic flux.
Holding force and lifting capacity of Automatic Lifting Magnet LI-120 are rated with steel EN S235. Most other
steel materials produce lower holding force.
Hardened steel conducts less magnetic flux than equivalent unhardened steel. Therefore, hardened steel has
lower holding force.
Lifting capacity of 120 kg is determined with steel EN S235. Most other magnetic materials result
in lower holding force.

e n g l i s h | 6
Ixtur LI-120
Air Gap and Surface Quality
Any material that separates the magnet's lifting surface from the surface of the load reduces the total magnetic
holding force. Reduction can also be caused by non-magnetic materials or by materials with weak magnetic
qualities, such as, zinc or paint or similar coating, rust, frost or air. This manual uses air as an example.
An air gap may also increase due to rust on the load surface, foreign particles such as metal chips from
welding, corrosion, and convexity or concaveness of the surface.
Before magnet attachment, both the magnet's lifting surface and the load material surface must
be cleaned of foreign materials to minimize the air gap that reduce holding force
Due to residual magnetism, the magnet's lifting surface may contain magnetic particles or pieces
which reduce the holding force
The load material surface may bend and become convex during the lift, which produces an air
gap and reduces holding force. Especially thin materials may cause this effect

e n g l i s h | 7
Ixtur LI-120
Material Thickness
In addition to ferromagnetic characteristics of load material, magnetic holding force is affected by the
thickness of the material.
The material's maximum conducting capacity for a specific magnetic field strength is achieved with a specific
threshold thickness of steel plate.
When the thickness becomes smaller than this threshold, the conducting capacity of steel plate weakens, and
at the same time, the holding force is reduced.
When steel plate thickness becomes greater than this threshold, the holding force is no longer proportional to
thickness, as the magnet has reached its full capacity.
For Automatic Lifting Magnet LI-120, the maximum magnetic holding force in the load material is rated with
steel EN S235, with minimum material thickness of 12 mm.

Power OFF No lights No functions
Start-up Two green lights are blinking for 3
seconds Normal use
Not starting Blue Light blinks once Operating temperature too low
Magnet ON (attached) Green blinking light Normal use
Magnet OFF (released) Red blinking light Normal use
Low battery voltage Yellow blinking light Connect the device to the battery charger
Charging Yellow light
Wait until the battery is fully charged, then
the device returns to normal functional
mode
Battery status check Blue light and Green blinking light, 2 to 9
times
Wait until the device returns to normal
functional mode
To reduce power consumption Automatic Lifter LI-120 shuts down automatically when it is left unused for 60 minutes. After this LI-
120 can be restarted normally.
Magnet is reset by pressing both buttons for 10 seconds
Residual magnetism
When Automatic Lifting Magnet LI-120 is either released from the load or shut down, the magnet's lifting
surface has a residual magnetic force. This residual magnetic force may lift a piece of 5 kg depending on the
shape and material of the piece.
Due to residual magnetism Automatic Lifting Magnet LI-120 may collect pieces and particles not meant to be
lifted. Please consider the residual magnetism of Automatic Lifting Magnet LI-120 when transporting, using,
maintaining and storing the device.
Due to residual magnetism the device may lift light pieces when the magnet is released, but full
holding force is not in use. Ensure always before lifting that the load is attached to the magnet and is
confirmed by the green blinking indication light.
Due to residual magnetism, magnetic particles and pieces may get attached to the magnet's
lifting surface; these will reduce the holding force during the lift.
Automatic Lifter LI-120 has an automatic demagnetization feature which is activated when the device senses
the lifting shaft elevation in magnet's OFF-state. Due to demagnetization, less force is needed to release the
load from magnet. Demagnetization stays active for 0.5 seconds.

Product Deployment
The battery of Automatic Lifter LI-120 is charged by the manufacturer, but full battery charging is required
before deployment of the device. Automatic Lifter LI-120 is ready for use right after charging. See the chapter
'Charging' later in this manual.
Start-up and Shutdown
Turn the device on by pressing the right button for 3 seconds. During start-up, you see two green lights for 3
seconds. After start-up the indication lights show the magnet's 'normal use' mode:
Green blinking light = magnet ON (attached)
Red blinking light = magnet OFF (released)
Turn the device off by pressing the right button for 3 seconds.
Charging
A battery charger is shipped along with Automatic Lifting Magnet LI-120.
Automatic Lifting Magnet LI-120 indicates low battery voltage by a yellow blinking light. When the battery is
empty, the device responds neither to the operation buttons nor to the movements of the lifting shaft, and the
magnet's latest state remains, for example 'magnet ON' (attached). When the yellow indication light is
blinking, move the device near to the battery charger and start recharging as soon as possible.
Plug the battery charger into a 100V - 240V electric outlet and connect the line cord to the charging terminal of
the device. The yellow light is on during charge. Charging ends automatically when the battery is fully
charged.
Detach battery charger from the device and from the electrical outlet after charging
Do not use the device for lifting when charging is ongoing
Do not use battery chargers from other manufacturers; only use Automatic Lifting Magnet LI-120
battery charger
Automated Use
Operating Information
Automatic Lifting Magnet LI-120 can sense the elevation of the load automatically. The device has a vertically
moving lifting shaft whose position indicates whether the device is lifted up or released down.
Lifting shaft in UP-position:
When the device is elevated, the lifting shaft goes to UP-position.
Own weight of the device keeps the lifting shaft in UP-position when the device
hangs freely from its lifting shackle.

e n g l i s h | 10
Ixtur LI-120
Lifting shaft in DOWN-position:
When elevation does not load the shaft, the lock spring is no longer restrained,
and the shaft returns to DOWN-position.
When the lifting shaft is released (i.e. when the shaft moves from UP-position to DOWN-position), the device
senses movement and changes the state of the magnet. At all other times the state is either 'magnet ON'
(attached) or 'magnet OFF' (released).
Operation instructions
1. Follow carefully the safety instructions when you connect Automatic Lifting Magnet LI-120 lifting
shackle to the crane.
2. Turn the power ON by pressing the right operation button for 3 seconds. Wait until the device is in
normal use state and start-up indication lights are no more shown.
3. Check that the magnet state of the device is OFF (released) i.e. red indication light is blinking. Move
the crane down and place Automatic Lifting Magnet LI-120 on the load surface. Move the device
downwards until the lifting shaft is released to DOWN-position.
4. The magnet state changes automatically to 'magnet ON' (attached).
5. Check that the green indication light is blinking, to ensure that the load is attached before you lift the
load. Ensure there is adequate holding force before lifting, and move the load smoothly.
6. After the lift, set Automatic Lifting Magnet LI-120 and the attached load down carefully and smoothly.
Move the device downwards until the lifting shaft is released to DOWN-position.
7. The magnet state changes automatically to 'magnet OFF' (released).
8. Check that the red indication light is blinking, to ensure that the load is released. Lift the device slightly
off the load.
When the magnet is OFF (released), Automatic Lifting Magnet LI-120 has residual magnetic force, which can
lift smaller pieces. To detach the load with less force, Automatic Lifting Magnet LI-120 activates its automatic
demagnetization feature. When the device is lifted off the load, the device senses lifting shaft elevation. See
chapter 'Residual Magnetism' earlier in this manual.
Do not detach the lifting shackle from the device when you connect the device to the crane.
Ensure always before lifting that the magnet state is ON (attached) i.e. green indication light is
blinking.
Manual Use
Automatic Lifting Magnet LI-120 must be connected to the crane with its lifting shackle in both manual and
automated use.
Automatic Lifting Magnet LI-120 is operated manually by using the left operation button.
When the operator presses the operation button, the magnetic state changes. At all other times the state is
either 'magnet ON' (attached) or 'magnet OFF' (released). Indication lights show the magnet state:
Green blinking light = magnet ON (attached)
Red blinking light = magnet OFF (released)

e n g l i s h | 11
Ixtur LI-120
ATTENTION! The magnet state always changes automatically to 'magnet OFF' (released) after the lift when
the attached load is set down and the lifting shaft returns to DOWN-position. See chapter 'Automated Use'
earlier in this manual.
ATTENTION! The left operation button cannot be used when the shaft is in UP-position. The magnet state
cannot be changed to 'magnet OFF' (released) during the lift.
Do not detach the lifting shackle of the device when you connect the device to the crane.
Ensure always before lifting that the magnet state is ON (attached) i.e. green indication light is
blinking.
Battery Status Check
Press the right operation button for 10 seconds. In this functional mode, blue light is on and the right green
indication light blinks 2 to 9 times depending on the battery status, and after that the device returns to its
normal use state. The number of green blinks indicates the battery charge percentage; 2 = 20%, 3 = 30% ... 9
= 90%

diameter 10,0 mm that has Lifting Capacity (WLL) 120 kg or more.
Authorized Service can replace the integrated battery.
If other defective parts are detected, repairs can be made only by the manufacturer or manufacturer's
authorized repair technician.
Ask your dealer about service and repairs.
Maintenance and inspection within operation
Is performed on a daily basis or at least prior to each work shift. Also whenever the device has been subjected
to abnormal forces, like a strong shock or falling.
 Clean the Device and Check that the device is undamaged on the surface, without bends, dents or
cracks
 Check that the lifting shaft (2) moves smoothly, without jerks. Clean and grease the lifting shaft with
vaseline if necessary. Do not use oil!
 Remove all dents and spurs on the magnetic lifting surface (7) that can cause increasing air gap and
decreasing holding force carefully with fine sandpaper
 Check that the lifting shackle (1) is properly connected
 Check that all functions work properly before starting work
 Before each lifting operation clean the magnetic lifting surface (7) and surface of load from dust, rust
and other dirt that can increase the air gap to maximize the holding force
Weekly maintenance and inspection
Is performed on a weekly basis in addition to the daily check list. Also to be performed whenever the device
has been subjected to abnormal forces, like a strong shock or falling.
 Check that the lifting shackle (1) is in perfect working condition, if not, change into a proper one
 Check products’ fastening bolts (9) and tighten when required (tightening moment 27 Nm)
 Check the locking ring (8) of the lifting shackle
 Clean the membrane of the lifting shaft (under the shaft collar (10)) carefully by lifting the lifting shaft
(2) and shaft collar (10) in an upright position. Also check that the membrane is intact.
 Check the magnetic lifting surface (7) of the device for flatness and wear. Uneven wear and deep
scratches, dents or spurs can create an air gap between the lifting surface and load, which will reduce
the lifting capacity. If more than 10% of the device’s flat lifting surface is affected, it should be taken off
service until the lifting surface can be reground. If regrinding is necessary, all lifting surfaces must
remain flat and in the same plane. Re-testing of the holding force is mandatory after regrinding

e n g l i s h | 13
