    I'd like to think i am an experienced operator of an end dump,frameless,and that i always do the right thing before,during,and then after dumping.

    well,this past week i have had something quite similar to the flu,all the aches and pain but no congestion/no coughing, and my last load for the week which ended early thankfully,had me commit an error. i forgot to dump both my trailer air bags and my trucks. i knew it as soon as i had it all the way up and the trailer sort of made a funny move to the left.

    lesson learned and potential disaster averted. thankfully i was dumping on level/concreted ground.ALWAYS stick to your script and no deviations. some may not drop the bags but my dumps go smoother and are more stable when i do.besides,the lever to dump the air is on my trailer so it must be there for a reason-

    It doesn't take much to get distracted enough to interfere with repetitive duties/routine. Whether it be home issues, illness or even the sun glaring through the glass. Thanks for sharing your close call to help us stay sharp.

    I don't have bags on my bucket but a friend that is a retired bucket driver told me when he urged me to end dumps from straight trucks. Always dump the bags!

    I agree, drop the bags! Stay to a routine and take your time.

    Most loads are not centered in the box. Be aware what side of the box the load is heavier on. As you raise the box watch what side the box leans. You always can try to level yourself on bad ground by dropping some product out and put the low side wheels on the product to level out.

    Air bags are stored energy like a coil spring when compressed.
    Drop in a dip while unloading and the bag compresses then shoots up to get back to level or over level. Causing the box to roll side to side. With the bags empty the stretch on the bags is not as pronounced, and the roll is taken up by the frame of the truck.

    One other tip. Watch when your backing up on uneven ground as to how the truck or trailer reacts and rolls. When you dump your going to go back over the same ground rolling and rocking. Don't like what you see backing up? Move over to a new spot where the ground is better.

    I drove a tractor with a 53 foot tridem end dump with twin lift cylinders hauling 100,000 lbs gross. Scary on the best of days. Routine was always important and puckering up in the seat helped.
