Common Used Tower Crane Models and Parameters
1. QTZ63 Tower Crane
This is a commonly used medium-sized tower crane with a maximum lifting capacity of 6 tons and a maximum working radius of 50 meters. The lifting height can reach 40 meters for the attached type and 25 meters for the free-standing type. It is equipped with a 380V, 50Hz three-phase power supply, and the rated power of the main lifting mechanism is 15kW. This model is suitable for residential building construction, small and medium-sized industrial plant construction, and other scenarios with medium lifting requirements.
2. QTZ80 Tower Crane
As an upgraded medium-large tower crane, it has a maximum lifting capacity of 8 tons and a maximum working radius of 55 meters. The attached lifting height can reach 60 meters, and the free-standing lifting height is 30 meters. The main lifting mechanism adopts a 22kW motor, and the slewing mechanism has a rated power of 5.5kW. It is suitable for high-rise residential construction, large-scale commercial building construction, and infrastructure projects such as bridge construction that require higher lifting capacity and working radius.
3. QTZ125 Tower Crane
This is a large tower crane with a maximum lifting capacity of 12 tons and a maximum working radius of 60 meters. The attached lifting height can reach 80 meters, and the free-standing lifting height is 35 meters. The main lifting motor has a rated power of 30kW, and the trolley traveling mechanism adopts a 7.5kW motor. It is mainly used in super high-rise building construction, large-scale industrial facility installation, and heavy equipment lifting scenarios with high lifting height and heavy load requirements.
Detailed Structural Details of Used Tower Cranes
1. Mast Section
The mast section is the main load-bearing structure of the tower crane, usually made of high-strength steel. Each section is connected by flange plates and high-strength bolts to ensure the stability of the entire tower body. The used tower cranes we provide have undergone strict inspection of the mast section, checking for cracks, deformation, and bolt loosening. The surface anti-corrosion coating is also maintained in good condition to ensure the structural safety during use.
2. Slewing Platform
The slewing platform is equipped with the slewing mechanism, lifting mechanism, and operating room. The slewing mechanism adopts a worm gear and worm drive structure, which can realize 360-degree continuous slewing, ensuring flexible operation of the crane. We will test the slewing accuracy and noise of the used tower crane's slewing platform, and check the wear of the worm gear and worm to ensure smooth and stable slewing operation.
3. Jib and Trolley
The jib is the key component for extending the working radius, and its length varies according to different models. The trolley travels along the jib to adjust the lifting position. We will inspect the welds of the jib, the wear of the trolley track, and the flexibility of the trolley traveling mechanism. For used tower cranes, we will also check the steel wire rope on the lifting hook, including its wear degree, broken wire condition, and lubrication status, to ensure the safety of the lifting process.
4. Operating Room
The operating room is equipped with a control console, display instruments, and safety protection devices. We will check the functionality of the control buttons, the accuracy of the load display instrument, and the effectiveness of the safety devices such as the overload limiter and height limiter. The operating room of the used tower crane will be cleaned and maintained to provide a comfortable and safe operating environment for the operator.

Application Scenarios
1. Residential Building Construction
In residential building construction, used tower cranes can be used to lift building materials such as steel bars, concrete blocks, and formwork. The medium-sized models such as QTZ63 and QTZ80 are very suitable for this scenario, as they have a moderate lifting capacity and working radius, which can cover the construction needs of most residential buildings.
2. Commercial Building and Super High-rise Construction
For commercial buildings and super high-rise construction projects, large used tower cranes such as QTZ125 are more suitable. They can provide higher lifting height and larger lifting capacity, meeting the lifting needs of heavy building materials and large-scale equipment during the construction process.
3. Infrastructure Construction
In infrastructure projects such as bridge construction, road construction, and water conservancy project construction, used tower cranes can be used to lift bridge components, construction machinery, and construction materials. The flexible operation and large working radius of tower cranes can effectively improve the construction efficiency of infrastructure projects.
4. Equipment Leasing Business
Equipment leasing companies can purchase our used tower cranes to expand their leasing inventory. With competitive prices and reliable quality, these used tower cranes can bring stable rental income for leasing companies and meet the diverse needs of their customers.
