Introduction
Tower cranes are widely used in high-rise buildings, infrastructure projects, and industrial construction.
Among different models, 6015, 6515, and 7020 tower cranes are commonly used in medium and large construction projects due to their lifting performance and working efficiency.
This article explains the main differences between these models and how to choose the right one for your project.
1. What Is a 6015 Tower Crane?
The 6015 tower crane is considered a medium tower crane model commonly used for residential and commercial construction projects.
Typical features include:Jib length around 60 meters
Medium lifting capacity
Good balance between efficiency and operating cost
6015 models are suitable for projects requiring stable performance and flexible installation.
2. What Is a 6515 Tower Crane?
The 6515 tower crane is a larger model designed for heavier lifting requirements and larger construction sites.
Compared with 6015 models, 6515 cranes usually offer:
- Longer working radius
- Higher lifting capacity
- Better performance for high-rise projects
6515 tower cranes are widely used in infrastructure and commercial building projects.
3. What Is a 7020 Tower Crane?
The 7020 tower crane belongs to the large tower crane category and is suitable for demanding construction environments.
Key advantages include:
- Larger jib length
- Higher load moment
- Strong lifting capability for large-scale projects
7020 models are often selected for high-rise buildings, industrial projects, and large infrastructure construction.4. How to Choose the Right Tower Crane
Choosing the right tower crane depends on:
- Building height
- Required lifting capacity
- Site conditions
- Project duration
- Budget and logistics requirements
Medium projects often use 6015 models, while larger projects may require 6515 or 7020 tower cranes.

Conclusion
6015, 6515, and 7020 tower cranes are all popular choices for construction projects, but each model is designed for different lifting requirements and project scales.
Selecting the right model can improve project efficiency, safety, and overall cost control.
