Flat Top, Tower Crane

Zoomlion T8030-25U

The T8030-25U is the first joint ventured flat top tower crane manufactured by Zoomlion and JOST after the Chinese maker purchased certain rights of the flat-top tower crane designs from the Bavarian-based tower crane company. A project team based at the Chinese manufacturer’s research centre in Germany developed the crane.

The flat top tower crane T8030-25U has a maximum lifting moment of 4925kN/m. The firm said that the design philosophy was to optimise the design of major structures, including crane top, crane boom, crane boom pull rods, climbing frame, upper and under bearing, cab, and improving the safety of components, including platform, handrail, connecting screw rod and safety rope in crane boom.

Zoomlion T8030-25U is a 25-tonne rated capacity flat-top tower crane with a maximum jib length of 80m and a tipping load of 3 tonnes.

Electrical Control System

With PLC control, the electrical control system enjoys better reliability and safety. Produced by professional manufacturers with advanced foreign technology, the electrical elements feature service lives that are 3 or 4 times longer than that of domestic products, fewer faults, easy maintenance and repair as well as reliable operation.

Technical features

The crane boasts multiple operation modes and wide applications. The crane can work in different forms: stationary crane with embedded outriggers, stationary crane with under-frame, stationary crane with embedded bolts and crane anchored to the wall, thus being applicable to various construction projects.
The complete machine adopts an internationally well-received beautiful shape;
The crane features high working speed and excellent speed regulation performance. Stepless speed regulation by frequency control, the world’s most advanced solution, is adopted for the trolleying mechanism and slewing mechanism, thus ensuring more stable and reliable operation ;
The cab is independently installed externally with good vision and large inner space, thus offering a good working environment for operators;
A variety of safety devices are equipped, which are all mechanical or mechatronic products that are applicable to severe working conditions, so as to ensure the tower crane’s reliable operation.
