It SUCKS!!!!!!  Blowin' at least 30 during these pics, gotta be gusting close to 35 or 40.  Half mile of open grass land behind me right down to the water.  Makes me edgy everytime that gust rolls through wonderin' how strong this ones gonna be.  Did I mention wind SUCKS!!!!!!

Have to say this is the best damn thing I've ever done to my truck.  Damn schwings are up so high in the ass end ya have to be a high jumper to get to that first step.  Cut off the bottom of the square tube on the factory steps, welded up an additional one, and bingo, a 20 inch adjustable step. 

Yea Matthew the wind can affect a pump and it at times does feel a little bit shaky when it is blowing hard. The step is a good idea ,most complaints I get are the steps are too low and get hit alot, just never forget to put it back up when your done or you will tear it off .

Man, from the looks of that step...if he leaves it down and backs into something, he'll uproot whatever he hits!

Nice job!  Good idea with the pre-drilled holes.

I'll admit its a bit beefy for the application, but the scrap bin had to right sizes in it, so it got used.  So far (knock on wood), I havn't forgot to put it up before transit, but I have before dropping the truck of my riggers.  Luckily though, it hasn't been low enough to make contact.

Nice idea on that step. Like it! I went to a concrete pumping safety seminar probably about 7 or 8 years ago and they stated not to set up in wind more than 45mph. 

45 mph sounds about right.  My op. manual for the pump says nothing over 48mph so I'd imagine they're giving a little wiggle room.  Problem around here is I never get steady winds.  I've been out on jobs when there's just a light breaze and then got hit with a gust coming off the water that damn near nocked me down.  Inland on the island's a little more predictable, but by the water like I was I'm always wonderin' in the back of my head, "how hard's the next gust gonna be".  Keeps ya on your toes I guess.

I have been told its not about the gust of wind.... The damage will be done with the constant pressure of wind against the boom . Dont know if im right but it kina seems logical

as a general rule 40mph and steady is a good rule of thumb.I have been hit with a 90mph blast (9th floor core wall) with a 52m,the boom brake couldn't hold and spun off building.Another time along foothills (2 52's) wind kicked very high,my boom held,other spun and hit crew.
