That's a crappy seat considering the time you spend in it and the concentration required.
It may not look it, but it's actually quite comfy on the whole. I suffer from ants in the pants a lot of the time, but I don't get that with this chair. However, it could do with being a few inches wider. It gets hot up there, and so it would be nice to be able to sit with my legs spread a bit more, air the old cream crackers and thighs.
Regarding emergencies, it depends. If there's a fire in the cab, the idea is shoot down the ladder if that's possible, which it very probably is. If not, then just wait it out on the back jib whilst the cab burns out. There's nothing flammable really apart from what's in the cab.
If lightning strikes whilst on the ladder, anybody on it is completely safe because the tower is designed in such a way that it travels straight down the outermost part of the structure. It virtually never strikes the cab because the crane itself attracts the lightning.
If it's medical, then it's probably a case of a rescue worker absailing with the operator strapped on...
The fan is upside down because the cab is so small that where it is located is the best place for it, and is there is nothing for it to rest on...it dangles.
Yeah, it sways quite a lot, but more to do with the how far along the jib the load is than the wind, as well as the magnitude of weight of course. The tower itself is designed to sway, not just the cab. The main effect of wind is that causes certain loads such as windows and sheets of wood to be caught & spin round madly, which can be quite frustrating when it comes to landing them in confined spaces without collisions. My current crane can officially work in winds upto 50kmph.
