Manitowoc 21000: Attaching the Boom
This takes team work!
The 1000 ton capacity Manitowoc 21000 holds up
its end of the boom by using its
mast as the hoisting boom. The Manitowoc 999 holds up the boom tip end as
the
21000 model guides the boom with its mast being raised to close the gap and
allow
connection of the pins holding the boom to the crane. I witnessed this and
found the
effort to be very smoothly coordinated by the assembly team. The whole
assembly
of the crane takes a few days!
