Trolley would not work on Igo T85A

Hoist and slew would work, but no trolley.  Obf was displayed on trolley drive.   Found trolley discharge resistor was damaged and broken.  Ultimately, was an input power problem that damaged trolley resistor.

Igo T85A Horn Honks when trying to Telescope up

When trying to telescope up, horn would honk.  Would go down, but not up.  Went through erection aid and all looked good.  Needed to readjust brake microswitch on telescoping drum.

Adjust microswitch by loosening locking nut and running down adjustment screw until “H” light comes on in CAN Open module (U213X).  Back off screw, just until the light goes off.

Trolley stopped working on Potain T85A (27148)

Customer called and said stopped mid-pick while trolleying.  Customer was able to hoist and swing, but no trolley.  Lowered load and cleared the hook.  Drive showed FST.

Went to Erection Screen and all sensors and switches were open.  The thought was that we lost +24V from transformer.  Customer went to get a meter, but didn’t work.  Got a 2nd meter and turned crane back on.  Erection Aid read correctly.  Trolley drive was flickering between FST and RDY.  Disconnected G33, and drive went to RDY.  Power cycled the crane and all works at this time.

New Memory Card in Slew Drive (ACS880) T85A

Installed a new memory stick in the swing drive on Igo T85A. Had to go to menu 74 and then to 11 to set the Supply Voltage to get started.

Then had to restart the drive and it went through a motor ID and run ID test. Once complete, had to restart the drive again and it worked fine.  The drive said it was ready to work, but was unresponsive.  Make sure to restart again.

Potain 27148 Trolley stopped working Fault FST

Crane stopped working one morning when the operator doing warm up.  Start the crane up and all the drives fire up but trolley immediately goes to FST.

We plugged in the handheld and crane works fine.

Got this from Tomas and he said you should try this if the crane is acting funny and you can’t get figure what it is.

Dusty,

Try this.

Hello Tomas,

We think you have an issue with H335H (green light). This light is connecting on Terminal G-33 (only with remote control ).

Try to disconnect it and work with remote control. Please find in attachment the light part number.

Best regards
