:URGENT: Lifting devices

hello there

does any one know why the development of the size and capacity of the crane has halted??

thnx

 

[richz]

anyone plz........... i really need sum info on this

thnx :O

 

[gordo]

ther's no demand for larger ones?

 

[richz]

ok thnx, are u sure abt that? cuz just the way u say it gives the idea that ur not all that sure

 

[A2RAYA]

that's right champ...the cranes they got now have done the job needed and thus far there hasn't been a job where larger capacity cranes need to be used...if that sounds more convincing

 

[gordo]

i dunno,
it seemed like common sense?

 

[richz]

o ok thnx guys just never thut it was so easy because i rember my teacher saying it wasnt that simple

You could talk about how larege cranes are impractical. Say a company was building a new sky-scaper which was to be 400m high. Using a 400m + crane would be stupid.
Think of a lever 400m long and you put something that weighed a couple of tonnes on the end. It would take a HUGE amount of force to lift it, defeating the purpose of the crane.
It's easier to use smaller cranes, and move them up when needed.

Hey Guys,

i believe that the reason is that there is no demand for the general use, standard building, tower crane

but there are specialty cranes that have been built

i believe that there is a 100m or 1000m long crane, functioning in a mine somewhere in western queensland or northern territory. for every 1 metre the operator box moves the end of the boom moves 1000m and travels of speeds up to 0-100km/h in less that 3 seconds

well thats my two cents
