QTZ250-7030-16T 7030 Tower Crane High Rise Building Tower Crane
This series of tower cranes has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all necessary safety devices, these cranes show a good speed-control capacity, satisfactory operating stability and high work efficiency. They can be widely used for the construction of high-rise hotels, residential buildings, high-rise industrial buildings, large-span factory buildings and tower-like buildings like tall chimneys.
The PLC (Programmable Logic Controller) adopted by our aerial equipment can timely diagnose the cause of breakdowns. The frequency converter easily realizes continuously variable speed regulation and greatly improves the stability, reliability, and operability of the control system as well as the work efficiency of the flat top tower crane. In addition, the electric components are introduced from world-class enterprises including Omron, YASKAWA, Schneider (TE) and MEAN WELL. They ensure a low failure rate of the electric control system.
1.It has ultra long arm and large coverage area.
2.The standard segment section is wide. Rigidity is good. Complete machine is stable and swings slightly when craning.
3.The standard segment principal branch is big.
4.The electrical system uses domestic high quality or importing parts. Its performance is stable and reliable.
5.The standard segment, drawbar, top-bottom turntable and other major components is welded by CO2 which penetrates deeply and deforms smally.
6.The slewing mechanism adopts winding motor which starts smoothly and reliably and places conveniently and efficiently.
7.Hoisting mechanism with good performance in speeding, lifting and declining smoothly.
