2. The Tower-Cranes-QTZ40 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 Tower Cranes boasts of multiple operation modes and wide application.
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 wall, thus being applicable to
various construction projects.
? The complete machine adopts internationally well-received beautiful shape;
? The crane features high working speed and excellent speed regulation performance;
? 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.
