Adjusting Weathervane Cable and Yoke

**This is extremely difficult with crane folded up, should be done with crane erected**

You will need very skinny 8mm end wrench and mini bit ratchet.

Remove cable clip, weathervane arm (careful to keep the washers) and motor cover (4 phillips or hex head screws)

Raise rubber seal to brake coil

Tighten the 2 screws on the bottom of the yoke to remove excess freeplay.  DO NOT REMOVE ALL FREEPLAY

Reinstall rubber seal in place.  Before reinstalling motor cover, loosen the 3 bolts on the weathervane cable bracket.

The cable and bracket will need readjusted.

Potain IGO T85 Hydraulic Pump not working

Went to start to tower up and moved toggle switch on remote to the right.  Didn’t hear the normal “whine” of the hyraulic pump.  It ended up tripping the breaker Q940M.  Flipped the toggle back and forth a couple times to get it to work and it didn’t.  Motor was VERY HOT

Took motor off from pump with the 4 allen screws.  Flipped the toggle a couple times and it broke free and ran

Re mounted motor and it worked like a champ

AMCS on Igo T85A will not trolley

The AMCS system did not record inner and outer limits for the trolley sensor.

Go to the sensor screen, and click on the “Gear” icon next to the trolley sensor

The top line of the should show the current position of the trolley.

Although you can set position 1 or 2 first, start with position 2 (the outer limit), so you can trolley back in and set the inner limit (position 1).  Once you position the trolley at the outer limit, verify the distance and sensor value and click the checkmark box.  Repeat for position 1 at the inner trolley limit

Crane lost slew function AFE1 Code on slew drive

Crane lost slew function. AFE1 displayed permanently on screen. If cleared, drive would shut down. Checked voltage at XD24-2 24V connection on slew drive. Voltage was present but not 24V. Checked XD24-1 connection at slew drive Voltage was present but not 24V. Removed the XD24-2 wire are rechecked and voltage was 24V. Determined K600M Contactor was faulty.
If a new contactor isn’t available. K466M (motor preheat contactor) is the same and doesn’t use the 13/14 connections. This a great contactor to use to get the crane up and running.

Removing outer jib, 104ft IgoT85

After you bring the crane into maintenance mode and get it in the position to start taking the Hydraulic cylinder,  jib attachments, and jib off.  The operator manual disassembly instructions do not match the actual process to remove the outer jib.

With the pictures above the picture from the manual tells you to pull this pin to get the cylinder off.  Which there is to much pressure on the cylinder to get that pin out with out possibly bending the Jib on the crane. When you get to this step of taking the Hydraulic Cylinder off you will want to revert to the edited picture above and pull that pin first.

The operator manual disassembly instructions do not match the actual process to remove the outer jib. When removing the outer connecting rod/hydraulic assembly, there is no need to remove the pulley pin and roller assembly as detailed in this step.

The connecting rod (4)(image below) pivots on a special pin with a through bolt. To remove the connecting rod (4) Remove the through bolt, slide out of the connecting rod pin (4) The sheave assembly that is detailed in the image below (1) is separate and will unpin without any interference from the Connecting rod (4)  

Jib hinge, Connecting rod, jib removal

The connecting rod pin fits into a slotted rail, the pin needs to be at the bottom of the rail and turned 1/4 turn to be removed. (Note the trolley cable sheave is installed and pined into place. The pin required to pin the sheave is the same pin used to hold the pulley holder (1) in place. There is some paint in the I.D. of the holes, it is recommended to install the pin first with anti-seize to help drive out the paint before installing the sheave. )

The connecting rod assembly can be removed without completely disassembling the assembly as detailed in the instructions.
