Rocky Mountain Crane Service Logs
Amber light on the control panel with grease symbol on, but grease reservoir full.
Light comes on when it’s working, and when grease level is low. Grease pump motor is 24 volts DC. Found 8 volts. Removed 3 pump bolts and water poured out. Circuit board was shorted. Replace assembly.
(Note. K600M must be engaged to activate greaser circuit.)
Operator complaining that the crane is kicking off when hoisting. Determined it is only in 3rd speed. Hoist speed sensor needs to be adjusted and the end of shaft needs to be cleaned of debris.
According to Ken (716-220-5153) only do this when adding the “long” antenna or you could damage the receiver (yellow box).
“S1” is trolley out first speed
“S2” is trolley in first speed
DIP switch #1 & #2
-Main power off, remove 4 screws on transmitter. Find DIP switch #2 and move it to its opposite position.
-Main power on, and remote on press start button. Crane should start up, but not honk
-Hold the start button, function button (black button on opposite side of start button) and S1 (trolley out first speed)
-This enters you into the service menu and toggle through the menu using S2 (trolley in first speed) until you reach RF Power (should read normal)
-S1 until the the RF Power says “MAX” (it goes normal, high and max)
-Press start button, function button and S2 and it read Result OK when complete.
-Shut off main power, switch DIP switch #2 to original position and replace cover
Customer says lost trolley and hoist functions (in/out & up/down). Told to switch to push button remote and all works.
Remove cover and check fuses under black caps (5)
At start up, remote does not connect to crane. K320 relay (horn relay) just clicks.
Remove J12/5 24VDC yellow wire from U230X
Remove A1 24VDC Pink and Grey wires from K100A
Jumper J12/5 to A1
Restart Crane
This takes the KK plug and its connections out of the circuit.
During erection, mast folds together but sensor S915S will not open and allow you to validate to move to the next screen. Disconnect G4 and the horn will honk. Reconnect after the next step.
Potain is aware and working on a fix.
ATV 58 drives that were originally installed on the crane have been replaced with ATV (MGC) 31 drives. In the “kit” there are also additional blocks and a time delay module.
I was unable to fit the time delay module on the rail with the other contactors. I ended up placing it on the rail directly below the resistors (see image). Time delay module needs to be set for .300 ms ( referred to by Tomas as .30 ms). Open the clear door and set the range to .1 – 1 s and the dial to 3. When wiring time delay module, you’ll see it 2 separate places on the wiring schematic. It should have an input on #15 and (xx). On the bottom, should be the #18 (which should switch to +24V when the module is activated (when module is activated, there is a small green light on at the bottom right corner). The other bottom socket (xx) should by ground (noted as 0V in schematic).
The connector block to add to K800M contactor (trolley) is the larger of the 2. It needs #53 and #54 connected.
The smaller connector block mounts to K940M (hydraulic pump for erection)
Image shows wire added to “jumper”, but just needed 1 wire removed.
After Dusty’s discussion with Tomas, Inductive detector for Mast Raising Control (B913N) has failed. Circuit is normally closed and setting off the horn. remove wire #11 or #61 in the G strip (folio 4/13 A-8).
