I have taken photos that could be the same situation. The only difference is the color of the pump.

As an operator you need to be aware that this type of reshoring system, by design, has a void area directly outside the lag boards. Even under ideal circumstances you need to set your outriggers on large deck plates. The contractor that you are pumping for should see that these deck plates are in place before you ever arive on site. This is just one of many times when the pumping company was not aware of the dangers and thought that it was safe. Three years ago I was on a similar job after an event just like this. It was a 52 meter pump. The bottom of the hole was full of dunnage that the operator had placed under his pads; he thought he was safe.

You as pump owners, salesmen, managers and operators need to insist on deck plates when in this situation.

Sure, you might be OK with just regular dunnage. But what guarantee do you have that you will be?

In NYC some buildings have basements that extend under sidewalks.

It is very important that the pumping company has/asks for all the information to insure a safe set up and pour.

Sit here - pour that... doesn't get it.

Pictures like these and all the facts that led to this need to be shared with all companies,and shared at monthly saftey meetings,instead of hiding the embrassment of the company and operator,I think every turnover needs to be adressed regardless,then and maybe then,we will never see other picture like this and it will only be our ability to overcome our mistakes to make as great as we can and want to be in this industry.

I agree.

Please feel free to use this, and any other information that you find on the site to help your fellow operators better understand what is is that is dangerous.

As always, if I may be of any help don't hesitate to contact me.

That is what ConcretePumping.com is for

EXAMPLE: 52M SCHWING

A. 36” X 36” = 1296” SQ   TRANSLATES TO    46psi on soil

B. 36” X 48” = 1728” SQ                                35psi

C. 36” X 60” = 2160” SQ                                28psi

D. 48” X 48” = 2304” SQ                                26psi

E. 48” X 60” = 2880” SQ                                21psi

F. 48” X 96” = 4608” SQ  (STEEL SHEET)        13psi

Does'nt look like his front outrigger is all the way out as compared to the other one.

sometimes they retract a bit when the entire pump is pushing them in

Bob, nice chart I've used option F before on a 61 meter due to the fact we needed to set the outriggers on the roof of an exsisting under ground parking garage.  It worked great!  It defiently took some planning but it was well worth it.  Just recently there was a misshape in my area where an operator had no pad out on asphalt near a storm drain and the outrigger punched through, making his day not so happy.  Fortuantly no one was hurt.  But this is a prime example why we always use outrigger pads no matter what. 

Maybe retired pumpers can put together something like the NTSB and investigate these things.  They can work as intermediaries between pumpers and insurance companies/building departments. 

These instances remind us of a golden rule: Never trust a contractor for the saftey of your set up. Only you know what you need to safely set up!!!!
