Rocky Mountain Crane Service Logs
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.
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.
