Re: Post a pic of your truck taken today
I have changed the way they are positioned with the holes being vertical. If cinder blocks are so bad then why is there a bunch of mobile homes being supported by them across this great country.
I have been a FireFighter for 10yrs now and we have never got a call due to mobile homes turning over or collapsing due to the blocks under them have giveing way.
But good eyes guys :tup:
As a Structural Engineer, I'm going to answer this (and yes, I know the subject is dead, but I'm cruising through this thread and living vicariously, so lemme be :rotf
There are two problems with the use of concrete or cinder blocks when supporting a vehicle: they aren't sufficient for load bearing with their cores laid horizontally (and will crush without warning), and even when used vertically, the distribution of load across the top face of the block has to be even in order to avoid point loading which can shear and collapse the block.
There is an acceptable way to use cinder/concrete block for the purpose, but why bother? By the time one sets it up to allow them to be used safely, you're better off with ramps.
There ya go!
