Hammerhead Tower Crane, QTZ125(6015)

, QTZ125 (6015)
Description

The QTZ125 (6015) hammerhead tower crane is well suited for various kinds of construction projects. Its maximum lifting moment is up to 125t·m which allows the maximum lifting load weight up to 8 tons. The heavy lift crane can carry the heavy load within a radius range from 3m to 60m. Such an effective working radius matches every need for material handling. In addition, this tower crane can be easily erected to a height of 46m without any wall anchoring measure. When anchored to the wall, however, the hoisting machine can reach up to 200m.
