K-10000 tower crane
K-10000 tower crane has a different counterweight arrangement than what is
typically encountered on tower cranes.
There are two kinds of Counterweight:
Fixed - straddling the CW Jib
at its outer end
Mobile - hanging in two CW Trolleys
|The CW Trolleys are individually powered to travel between their minimum radii and their maximum radii.|
CW Travel is semi-automatic.
It s under Operator control, but only possible when the Load Condition either allows it or requires it.
CW Travel is only allowed when all other tower crane motions are at standstill.
CW Trolleys are Parked, either at their minimum radius or at their maximum radius, while the crane is working.
smaller cluster is the the Small CW Trolley parked at its max. radius,
under the Fixed CW. The large cluster is the Large CW Trolley parked
at its min. Radius.
of all Counterweight Blocks is done with mobile crane
as part of the erection of the tower crane.
