We have a Putzmeister 2109 hp trailer pump that we are using for high rise aplication. The unit has for anchor points on it one above each out rigger. We are going to instal anchors into the concrete billow each point. Does anyone have any idea how many pounds of force the anchors will need to withstand when we chain the unit down? Any input from people who have delt with this type of equipment would be appreciated thank you.

done many of hirise 20to80 stories 2100/14000 putzs never bolted on down just sit legs on timber and make sure you secure ground line properly

I always secure the pump. I use 7.5 ton chain comealongs with 10ft of chain. I use the comealongs to adjust the pump if it moves and to make sure it doesn't move much. They have really helped in the past.

You have to control the line surge to zero with trust blocks. You can secure the the pump all you want. If you don't control the line surge the pump will fail at some point.

How high are you going ? 10.20 30 stories?

We only used straps but that was on a 1409.

If I would want to be sure... If I'd use chains that can handle 7,5 tons I'd make the ancors handle 7,5 tons aswell. That should do it shouldn't it??

We have 3 large thrust blocks in the horizontal run of the system. At thiss point there is no line surge we wiill ad more if needed as we go higher.  When we top out this job we will have 130' of horizontal 430'of verticle going into a 38m placing boom. I am asking about chaining the pump down to keep the stresses on the clamps between the pump and the thrust blocks to a minimum. A putzmiester rep is looking into it right now but i was hopeing some one might have come across thiss befor so i could get some numbers to our enjeneer sooner than later. That's why i was hopeing to hear from some one that has anchored one down before I can't give the engeneer guess on what should hold.

You are on the right track. Secure the pump and some have used turnbuckels at the reducer and pipe into the diversion valve.HD bolt on clamps are a must. If this helps you can calculate the concrete weigth in the stand pipe as needed. Cubic foot of crete weights 150 lbs. Multiply 150 x vertical hight of stand and divide by 7.33 . To figure psi exerted on standpipe multiply 1.1 x vertical .
