Every HDT 80 with a serial number that starts with a 400 number has a override option. If you overload your crane and you can’t hoist up or down because you overloaded the crane hold the start button down while hoisting down.
HDT 80 hoist line for erection and dismantle
HDT 80 When erecting or dismantle make sure you have slack in your hoist line while folding the jib. It does not have auto winding on the hoist drum so it can get supper tight and there is no limits to stop it. click on the link to see in the manual where you need to make sure you have slack in your cable. It is best to have about 10 ft of slack in your cable.
HDT 80 limit switches
While erection and dismantle there is no limit switches that will stop you. Also there is no 125 limit for your hoist so you do not want to get your hoist rope tight at all or you will be bending and breaking stuff.
Top Site & Pairing New slewing encoders on HUP
When setting up top site on a hup or pairing new slewing encoders there is a few more steps that you need to take that doesn’t explain in the manual. I have added some key notes in the top site chapter in the manual to get the job done. top site manual
Torch is hitting the plate and not spacing correctly
When cutting something out on the plaz the torch will start cutting and drop it’s tip into the metal plate. Which you will then have a fault and will have to reset. If your settings are correct on your programming the tip of the torch there is something wrong with it and needs to be replaced.
Potain IGO T85 Hydraulic Motor not working
Was trying to tower up and let Jib retaining rope out. Toggle on my remote was to the right on mast. Hydraulic motor would not come on and wasn’t able to let out the Jib retaining rope. Breaker Q940M was not tripped. Looked at my Erection aid and where S916S & S918S was just —- Which it should have been reading S916S. Switches were good, checked B911N (Inductive control detector of retaining winch) will also put —- if it’s not reading correctly. Had 48V at G27. K916A was not Acted on. Had 48V at K916A. Wiggled contactor and orange plunger on K916A was Acted on. Erection Aid was reading S916S. Hydraulic motor and Jib retaining rope started working. Need to probably replace K916A
219 stuck on 99% moment
Crane won’t go to 100% moment and load. Can’t change it from 99% to 100% on the display for your maximum moment and load. Need to go to the CCT U246X and put in your tech code then go change the moment and load to 100% then you can go change it on the display in teach in and crane configuration. To access it on The CCT

Liebherr Jib pin
Need to make sure you pull down on the cable that is attached to the jib release pin while folding up jib. It can get stuck and not slide properly and will bend plate. Which won’t latch properly.
Liebherr auxiliary motor went down.
When trying to fold the jib out it would stop and throw an error on the remote E 2651. Which means Torque limit motor reached. When using the motor it was putting out 11 to 15 amps before kicking out. A good motor at full speed puts out 5to 8 amps while working properly. You can find your amp pull right on the drive +k-T1. Replaced aux motor and was drawing 7 amps
T85 Didn’t have any functions after erection
Crane was fully erected had jib retaining pin engaged and button pushed to validate crane. Switched it to C4 no functions switched it back to C3 got functions back. In erection aid S916S was flashing and S910S was flashing. Crane had a Jumper in between G25 and G27 Pulled jumper erection aid went from S916S flashing to S918S fixed which erection aid is reading jib retaining pin is locked. After switching to C4 S910S was still flashing need to switch back to C3 and put your toggle on your remote to mast and re validate jib retaining pin then switch to C4 then had all functions.
