Please make sure you use enough cribbage under your pad to support your concrete pump. 9 out of 10 concrete pump operators who flipped their pump over wish they had used more cribbage. 

Why isnt it 10 out of 10. Pretty sure everyone regrets flipping a truck. Just curious on where that information came from.

ok, 10 out of 10. 

There is no research on how many wish i am just guessing. I think you are right, it should be 10 out of 10 but maybe a cowboy or two will claim it was not their fault and had nothing to do with cribbage and they might be right.

Well yea that makes total sense. When your pad bends it's no longer distributing the weight of your foot...so essentially it'll push the pad through just like it'll push through soil.

Cribbage is a game, the correct terminology is Cribbing or Blocking.  1926.1402(a)(2)

"Supporting materials" means blocking, mats, cribbing, marsh buggies (in marshes/wetlands), or similar supporting materials or devices. per OSHA. 

• Blocking is commonly used to provide a foundation for heavy loads such as outriggers.
• Cribbing is used when a heavy load must be supported at a height greater than blocking can provide.  Definitions from Altec website.

I call it dunnage, always have always will.  The important thing is to do it, not wether you know the correct word to define it.  But Cribbage is always a game.
