Descriptions of Tower Crane
The 8T QTZ125 tower crane has a lifting torque of 125 tm, its max lifting capacity is 10 tons. The max lifting capacity at its max radius of 60 meters is 1.5 tons. The hoisting, slewing and luffing mechanisms all adopt variable frequency systems, the frequency converters are from Yaskawa, Japan. The tower crane operates smoothly with minimal shock, meeting all of the work site requirements.
