I Am A New Member From Fla where Consruction is Booming ,, I have Read the hose Whipping & liability forum & this 1 , I have been running a boom Pump for almost 11 yrs now & I must agree Hose Whipping is a Problem , but In My Opinion , the solution is not to make the tip hose out of metal or any other hard substance, My question is this , would you rather be hit by the Hose or a Metal Pipe , there is a reason the manufacturers use hoses instead of pipes or hard Plastic ect.I must agree With Marcus & rocky1 in thier post in the original post ( Liability & Hose Whipping) I personally like to be on the deck of my pump If at All possible , There Are times when im 20 stories up in the air on the placer & cannot even see my Pump let alone hear it, but I expect my oiler ( when im on a high rise) to Idle the trk down if & when the driver runs the hopper dry. I had a 61 meter suck a big gulp of air a few mnths back & the oiler not only idled the trk down he also reversed the pump to push the air out in the hopper not the end of the hose , yes the driver got a concrete bath but he will not make the mistake of running the hopper dry again ...

when i worked for pumpco in ocala the branch manager there would not allow us to use regular size tip hoses we HAD to use a 4 inch hose and therefore had to use the 2 foot reducer , when priming out i had to remove the reducer or else i would plug up 75% of the time. same for sponge back ( removed reducer ) the sponge would not make it in the 4 inch hose. i can recal and still show some scars from a blow out i had with that set up. I had just finished pumping an 8 yard driveway witha 42m ( pointless job LOL ) and was pumping down the hopper like every day, i would pump until the mud reached the rock valve and switched one time, moved the boom and laid down the hose and reducer to remove for sponge. Well as i was removing the clamp it suddenly blew apart knocking me on my arse a few feet back. a rock pack had formed in the reducer and had pressurized the boom with out me knowing. i now NEVER open reducer clamps with out using my 5 foot bar . but in all honesty i would say that over 50% of hose whipping accidents occur with reducers

good post Mudslinger Sincerely,MarcusOperationsThe Operator Training CenterOperations@OperatorTrainingCenter.Com

if im not mistaken adam you do alot of tilt up work and thats mainly 4k-5k psi regular rock mix. Thats all ive ever seen used , but we dont do GCM pours for tilt up , its mainly sunshine structures . Ive never used my 4 hose exept for elevated decks or high rise applications ( light weight ) and wall/column pours, 5 is the way to go for me for daily work as well. As for flow rates i try to keep it steady ( aprox 1/4 volume & 3/4 throttle ) finishers down here dont seem to complain much about splatter but they HATE full flow streams haha espesially 5 inch streams ! ;p
