TC7520-16(QTZ250)

The product is new developed. The lifting arm is  good in feasibility and availability. Lifting mechanism and luffing mechanism adopt variable frequency motor, slewing mechanism adopts torque motor. The maximum hoisting weight is 12T. The longest jib is 75m, can meet the application for the building with large span. Adopting the H3/36B plate type standard section which can exchanged with POTAIN's one. The transportation is convenient and the operation is simple and safe!

Applications: TC7520-16(QTZ250)
It is suitable for construction within large scale and crossing intensive tower crane groups, like super high- rise building, large hydropower station, large bridge construction, port with heavy hosting weight, metallurgy company and petroleum company in large scale.
