Deployed tower ladder, should the wheels come off the ground?
Got into a debate about this after speaking with a professional crane operator. We have a pierce 95' aerial platform. For as long as I can remember, i've been taught that the outriggers should be extended until the bubble is taken out of the tires.
Problem is, with removing the bubble I have on multiple occasions been able to get the outriggers to actually rock off the ground by an inch or so, which would imply that the tires are still bearing the weight and the load is unsteady.
I was told by a professional crane operator that a mobile crane is NEVER to be operated unless every tire is fully off the ground and the outriggers support 100% of the load. Reason being, we want the point pressure of the outriggers in order to obtain much higher stability.
So whats the right way to go here? I doubt the crane operator is wrong.
Also, at work we have the aerialscope seagraves and they also have to come off the ground fully to operator. But they have 6 outriggers instead of 4.
