The boom angle of the large luffing tower crane is between 17 and 83 degrees, which greatly broadens the capacity and working range of the equipment. Compared with the horizontal arm tower crane, the large elevation angle of the boom is equivalent to increasing the height of the tower body, and the effective extended working range is almost a hemispherical space with the boom length as the radius. This is of great significance for the construction of the main structure and the hoisting of the towering components on the main structure.

2. 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, less
faults, easy maintenance and repair as well as reliable operation.
3. Technical features
? The crane boasts of multiple operation modes and wide application;
? The complete machine adopts 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
? The cab is independently installed externally with good vision and
large inner space, thus offering a good working environment for
? 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.
