Very large Mobile Cranes

[drivin_me_nuts]

Quick question for those who might know,

What license(s) would a driver to operate a machine such as this?




Terex AC1000 or it's bigger road going models.

To drive it on the road you need a Class 2 "C" Licence

To operate it you need the specific crane ticket (unsure what the correct title for it is)

As above, as far as I have understood it cranes are ridgid so they are class 2. The firm down the road from us only pays their drivers class 2 money aswell, although most of their stuff is smaller than that.

Not that long ago these things could be driven on a car licence, but the rules were changed that you require a class 2 licence to drive them

Bloody hell... that's enough to give someone like me (only a car license) nightmares!

I think some of the larger ones have a headroom just a couple of inches under the top of most EU bridges and the swings front and back... shudder.

You work with things like that?

.. That page you linked to.. Bloody hell, this will be one hell of an insturance claim

[drivin_me_nuts]

A question for you P&M...

how do the very cranes keep enough cable on board for the very large sheaving operations? Take your picture for example, if you needed to drop that cylinder down 100m below ground... presumably the cables are on twin drums. Can you add more cable to the drums dynamically, or is the max vertical lift height of one of these cranes limited to boom height and lufing jibs?

[drivin_me_nuts]

Yep: thanks

700m, so plenty then. The torques involved in lifting a full drum on a superlift must be very substantial. The mechanics involved in mobile cranes is eye-watering.

OOOoooffff

blooming heck!!!

with regard the pic of the mobile that burnt out, how was it recovered???
big wrecker

[jimmyjimjim]

And also, what was replaced? I'd have assumed the strength of the boom would have been affected by the fire and needed replacing, along with a whole host of related components; not sure much would have been salvagable?

Recovery of that fire damaged mobile crane would be an interesting one! It would take a lot of work in situ to make it towable, but damaged tyres removed and replacements fitted, and body/panel damage that would prevent movement cut away, and some other temp repairs to hydraulics would be the only way to get it moving some shape..

Rebuilt and working again

I thought it got butchered and made into a pedastal crane.

only on mobile, so am brief - you would be surprised that it had obvious perishable but not much more.

I thought the fire would have affected the boom etc, but no.
Not as fierce heat as the pics may let on.

Thanks. Wouldn't like to be the person certifying it for use again, though.

You are quite correct, it is now a pedestal crane.

But it hasn't had much luck since......
