as i see the some pictures of the pumps being shortrigged i just wonder why because in ACPA'S safety bulliteen says that "DO NOT PARTIALLY EXTEND OUTRIGGERS" because of the fulcrum that supports every leg especially on front outriggers, im doing shortriggin here but its fully retracted. any comments or suggestions? |

You should look at the spec's of that particular unit. Most outrigger reinforcements are placed at the fuilley extended position. Short-rigging could compromise the structural integrity the engineers had in mind. |

Not if the "short rigging" is done on the "non working side"? There is nothing wrong with short rigging as long as it's NOT a load bearing outrigger. (As long as you DO NOT boom over a short rigged out rigger) |

Thanks for the correction TooTall - your right - If your going to load the outrigger with the boom thou it should be fully extended as the design implies. |

if it's a telecopicing outrigger ---- fully extended or fully retracted. first reason is as chongliyan said, fulcrum. second reason, 3/4 extended can look alot like fully extended at a glance with a short memory. http://www.concretepumpers.com/pdfs/05003_shortrigbulletin.pdf |

for all u shortriggers what happens when you got to circulate your mud while waiting on a cleanup load, or have to blow out into the mixer, when in all the acpa guidelines it says dont work outside the centerline of your extended outriggers? just some things that i could see having to do possibl, IF I EVER DO SHORTRIGG. Not sure please inform me all you brave shortriggers |

Check it out Wizard, Here is the safe/stable working radius of a properly "short rigged" pump. However it is an "X" frame and I know your current pump is different. You CAN recirculate and if the mixer you need to pump into is out of your "safe radius"?....... Move the mixer. If it is still against company policy to short rig then disregard all the above and keep putting all fours, all out! |

PS... The most common accidents involving a "short rigged" concrete pump is when the operator is asked to boom accross the street to blow out or pour a pier pad and forgets that he is short rigged!!! (Because it's out of routine) I have a little safety tip for "short rig" set ups... I take one of my orange cones and put it up on top of the cab, over which ever side I'm short rigged on. Every single time I even boom close to the cab, I notice the cone! The simple act of putting the cone up there makes one more aware of the situation, then it becomes part of your "routine"??? |

wow it still seems like very limited work area over the front outrigger. A guy would almost need a spotter while shortrigged, good info it sure does add extra danger to an allready dangerous, and stressful job. Are there a significant amount of accidents that happen from shortriggin? My hats off to all that do, i would like to personally be on site of a setup like this to see first hand do's and dont's of the setup. good stuff PUMPON! |
