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.

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

600 Series Anchors

On P62US (same as P62B) anchors, tapered pins (longer of the 2 pins, 60mm and 59mm) go through spigot and template (tower).  These will be the bottom tower pins.   Straight pins (59mm) go through anchor and spigot.

Measure the pins and fishplates )spigots) to be sure.  Also check for which holes to use on the template.

When attempting to swing crane shutters but does not move

Crane will not swing at start up, but will kick out of weathervane.  Manually lift swing brake and attempt swing again, and crane will swing normally, however will not brake normally.

Look for +20VDC at V100F, and verified.  Look for +20VDC at K600M #7 and verified.  Found no voltage at K600M #8.  Although contactor was energized, contacts were not closed.  Replace K600M.

**Note** this was specifically on a Hup 32-27 which only has 1 swing motor.  Condition may be different with 2 swing motors on Hup 40-30

Transition 4

When operator would stop swinging, the Slew Drive would shut off just before or just after the brake would set.  NO active faults, but fault history showed code 00011.10002 Transition 4.

Verified DIIL input to slew drive.

Per Refik, changed Parameter 21.01 (21 – Start/stop mode .01 – Start mode) in drive from “Automatic” to “Constant Time”
