K-10000 tower crane
|While the Tie Bars may look as wire from the ground, they are actually substantial tubes.|
|Pulling the Tie Bars to the Jib attachment points is done using a hydraulic tightening device, very similar to the system used in Slip Forms.|
|The ends of the
red beam bolts onto the outer ends of the left and right Jib Tie
The gray beam bolts onto left and right Jib attachment arms.
|Because the tightening is a true axial pull, the pin holes will come together to exact alignment, facilitating pin insertion.|
|Users of very early Climbing Cranes, tower cranes gaining height by climbing from floor to floor in Hi-Rise buildings, may recognize the pulling device.|
