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)
