Assembling the crane

Big cranes like the SL16000J-H can’t travel along a road.
They have to be transported to a site and assembled.
It’s a job that has to be done in an organized and systematic manner.
The assembly takes about a week.
Few people know the ins and outs of assembling a crane.
Let’s see how it’s done!
