Liebherr / Liccon

As a part of crane operator training, entering data in crane’s computer is one of crucial steps of learning to setup and operate crane safely.

Liebherr cranes have their own crane computer calle Liccon – stands for Liebherr Computer Controlling.

Liccon allows crane operator to enter information depending on crane’s configuration, so the computer can work out what the crane can safely lift at all possible distances and hights with different boom angles and lengths, basically said.

Every crane configuration entered into the computer is given a unique code. That code is displayed at the top of the screen. Crane operator can enter the code directly into the computer for a given crane configuration without going through the steps of adjusting all the data separately.

Information entered is: type of boom and boom extension, amount of counterweight on crane, length of outriggers used, slewing area and reeving of main hook block. All data is entered via corresponding “F” keys directly under each data value.

Once all data is entered, basic load chart picture appears, where crane operator can compare SWL with different boom lengths and at different radius; enabling the crane operator to make informed decision about how much boom to extend for the lifting task.

Load charts displays the configuration code, radius, SWL, boom lengths, number of falls, percentage of each boom section to be used for chosen crane configuration, type of boom and boom extension, amount of counterweight on crane, length of outriggers, slewing range.

Once all data is entered and operator is satisfied with the settings, Liccon goes into the working mode screen after pressing F8 – OK button. Section on the screen that has boom sections percentages highlighted determines telescoping sequence which is automated after crane operator switches to main working screen and chooses ‘telescoping’ function of joystick.

Liccon liebherr computer working screen displays utilization chart, winches and their movements, any warnings, wind speed (if anemometer is installed) SLW and tare weight, radius, boom angle, boom length with current percentages of each section used, possible head height and options.

To the right of the screen there is key pad for entering more adjustments.

Via the key pad, crane operator can access all functions of Liccon – go back to the setup/load chart screen, retrieve information about outrigger pressures or adjust outriggers, go directly into telescoping mode, enter the configuration code, adjust speed of movements and more.

With telescope button crane operator can access telescoping adjustments screen directly.

Note the difference between the two pictures.

From the same key pad, crane operator can go straight to the outriggers screen:

Here the crane operator can see all outrigger pressures, adjust outrigger lengths and height, see current crane level and main lifting data.

Other important function that can be accessed from key pad is adjusting the maximum speed of crane motions.

Besides entering the maximum speed, in this screen winches can also be completely blocked to prevent undesired movements made by mistake.

Maximum speed can also be altered via joystick directly – by pressing “rabbit” button.

After pressing high speed button, change is displayed on main working screen with rabbit symbol:

  1. Enjoyed viewing your liebherr liccon info. Could you please advise on where to find more info on these types of computers. dvd,websites,online tutorials. Thankyou.

  2. Keypad functions.More explanation of the F-1-8, button functions. Is F-2 for main boom length or just main boom mode? F-3 for jib mode/length/ offset? What does K and F do on keypad? Any other info not mentioned above that would aid me in operating setup. Thankyou.

    • Jut to chose the mode. F1 – in load chart screen you scroll to the next radius page.
      T – telescoping boom (F2)
      *one next to it “F3” with ( — ) inside the square, you can change for any fly extension mode
      **Boom length is decided in two ways:
      from a load chart, when you scroll across with the white arrows for different boom configuration (hence different boom length, often) if you press OK – your configuration and length is chosen. As soon as the working screen loads, after you have confirmed boom config, flick to ‘telescoping mode’ and the chosen configuration is telescoped out.
      Or you can go directly to telescoping screen and choose boom config there.
      Note: telescoping procedure can be carried out from either screen mode.**
      F4 – you chose amount of counterweight on crane.
      F5 – width of outriggers utilized.
      F6 – 360 degrees slew or 0 degrees over rear
      F7 – number of falls of rope
      F8 – OK – after you have used ENTER for all changes you have made or after you started the crane again and are using the same configuration as last time (after break, for example) so there’s no need for ENTER since you haven’t made any changes in configuration.

      This is only for main configuration screen.

      F buttons change their functions as the screens change, look at the rest of pictures and examples. Let me know if you need further explanations.

    • On the right hand side – K and F you will often find without function – depending on the crane. Tip: never input the configuration code, let the computer choose the correct one!
      Good luck.

  3. Would you happen to have the same information for the16000 manitowoc? This website is awesome! Thankyou and I hope I’m not becoming a nuisance. Knowing the updated computers is always a good thing. Regards- John

      • HI Admin i have been tested on a liebherr 6 months ago and passed the test , also with the bluetooth set . but next week imoperating a 250 t liebherr and Ive forgotten the computer almost 50 % can you help pls.

        • HI Marcel,
          what exactly are you after?
          What model is the Liebherr that you will operate?
          What other cranes have you operated?
          At the start, I can suggest you go slow with the LICCON – read every little thing on it, in order. It is self-explanatory, if read and interpreted correctly.
          Go from the top across to the left and then from top to bottom, left to right.
          Read, compare and adjust data like boom type, amount of CWT, length of outriggers, reeving and the slew.

          I’m guessing you won’t be asked to set up the superlift by yourself or be in charge of installing it.


  4. hello friends

    I have a liebherr crane ltm1200 mod.1993 and i want to know how can i adjust my outriggers.when i extend them they fall down they dont come out straight


    • Hello Dimitrios,
      outriggers on your LTM 1200 (6 axles 59t counterweight, 55m boom?) are two-stage outriggers which have adjustment at the top and bottom, depending on model. You will notice big bolts and nuts on which outriggers glide, can’t miss them. If your hard plastic pads (Teflon) have worn away, you might need to replace them in order to be able to do adjustment.
      Also note that outriggers can never be totally horizontal, there has to be some play which makes them sag – not be straight. If they were completely tight, they wouldn’t be moving, friction would be to great.
      Once you have them adjusted to your liking, make sure they are greased regularly underneath where they glide on plastic pads to prevent wearing and make them move easier in/out. If you never stand on top of outrigger, you might want to put some grease on the top side as well – 2 stripes – you will see where it needs to be greased. Be careful not to stand on grease!

  5. Dear Sir ,

    May I know the meaning of each figure displayed at the screen during working (not during setup) . Thanks for your kind reply .

    Best Regards ,

    • Hi Simon,
      Liccon is very user friendly and self explanatory. Working screen shows with setup config code, utilization chart, maximum capacity, weight lifting at the moment, boom length and angle, boom sections and their percentages used, tare weight function and error sound cancel. If you are interested in any particular pictures, please send me a copy and ask specifically, I will help you.

  6. have an LTM 1090.4 crane
    The LICCON system showed the following errors

    1- E 194083

    2- E 394011

    3- E 494011

    Could you please assist me about the interpretation of these errors and troubleshoot them.

    with regards

    • Hi,
      you should refer to the back of your operator’s manual, all errors that can be taken care of by operator are listed there; others will have to be lloked into by a certified Liebherr technician.


  7. Viewing liebherr LTM 1055-3.1,liccon info.Could you please advice on where to find more info.on these type of computer with picture with keypad function .please reply me at my mail,thank you.

    Best regard
