• Hoisting mechanism: QPL2010D; power: 75 kW; rope capacity: 1000m;
• Slewing mechanism: HPW75F1.130C; power: 2×7.5 kW; 
• Trolleying mechanism: BP75A; power:7.5 kW
• Types of tower crane: stationary crane with embedded outriggers, stationary crane with embedded bolts, stationary crane with under-frame and mobile tower crane.

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 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. 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..
