6-ton tower crane: The preferred model for small-scale projects and lightweight construction

 

 

 

 

 

news-550-733

The 6-ton tower crane is a type of light and general tower crane. It is the most basic and widely used lifting equipment available on the market, featuring a compact body, quick disassembly and assembly, flexible relocation, and high cost-effectiveness. Its near-end rated load is 6 tons, while the far-end lifting capacity is relatively light, making it suitable for projects with small loads, low floors, and small construction volumes.
Applicable engineering scenarios:
- Multi-story residences, renovation of old residential areas within 6 floors, village construction
- Small-scale municipal roads, pipelines, rainwater and sewage renovations, small pump room projects
- Small factories, warehouses, guard rooms, ancillary buildings
- Transportation of light components, lifting of prefabricated small items, material hoisting during the decoration stage
Core advantages: Small footprint, quick installation, low fuel consumption, simple operation and maintenance. It is suitable for small-scale projects with short construction periods, small loads, and limited sites. It is the main model for rural areas and small-scale infrastructure projects.

8-ton Tower Crane: Versatile Model for Small and Medium-sized Buildings and General Construction Sites

The 8-ton tower crane is a medium-lightweight main type of tower crane. It is also the most widely used and versatile model in current construction sites. It takes into account both lifting capacity and working radius, has balanced performance and a low failure rate. It can meet the needs of multi-story buildings, as well as small high-rise buildings and general industrial projects. Its comprehensive cost performance is extremely high.
Applicable engineering scenarios:
- Small high-rise residences, resettlement housing, affordable housing, schools, hospitals within 18 floors
- Ordinary commercial buildings, street complexes, community supporting buildings
- Standard industrial parks, steel structure factories, warehousing and logistics parks construction
- Inland ports, small port areas for general cargo handling and transportation, ordinary steel handling and transfer
- General bridges, municipal venues, retaining walls, pipe galleries projects
Core advantages: It is compatible with the vast majority of conventional civil engineering projects. The remote lifting load is stable, the variable frequency operation is smooth, and the maintenance cost is low. It is the preferred model for small and medium-sized projects that "won't make mistakes" and is the most reliable choice.

10-ton crane: Main model for mid-to-high-rise, heavy-load and high-efficiency construction

 

The 10-ton crane is a medium-sized and large-scale engineering-specific model. Compared to the 8-ton crane, it has stronger overall rigidity, greater lifting margin, and a wider coverage of the main boom. It can meet the high-strength lifting operations of large components, heavy materials, and high floors, and is suitable for key engineering projects with tight schedules, large scales, and high standards.


Applicable engineering scenarios:


- Mid-to-high-rise residential buildings, large commercial-residential complexes, landmark buildings


- Large-span steel structure factories, large industrial parks, industrial complete equipment lifting


- Medium-sized bridges, elevated municipal facilities, large pipe galleries, water conservancy key projects


- Port storage yards, coastal infrastructure, small and medium-sized wind turbine accessories, heavy building materials handling


- Key projects requiring long-distance, heavy weight, and high-frequency lifting


Core advantages: Adequate lifting capacity, good wind resistance performance, high operation efficiency, which can effectively reduce lifting times and shorten the main construction period, and meet the requirements of high-standard, large-scale key engineering projects.

 

 

12-ton crane: Specialized model for large-scale heavy-load, super high-rise, and key projects

 

The 12-ton crane is a large-scale heavy-load high-end model, serving as a "heavy equipment" on construction sites. Its overall structural strength is high, with a large lifting redundancy, a long boom, and a large attachment height. It is specifically designed to handle high-difficulty working conditions such as super high-rise buildings, large-span structures, heavy steel frameworks, and large-scale lifting tasks.


Applicable engineering scenarios:


- Residential buildings over 33 floors, office buildings, and urban landmarks


- Large-scale steel structure projects, large-span venues, convention centers, and stadiums


- Large bridges, cross-sea projects, elevated hubs, and major municipal key projects


- Large-scale port heavy equipment handling, wind power equipment, and large-scale mechanical component transportation


- Large factory areas, heavy industrial plants, ultra-high, large-span, and heavy-load specialized projects


Core advantages: Strong heavy-load capacity, good high-altitude stability, excellent anti-overturning performance. It can easily complete the lifting of overweight, oversized, and super-high components, making it the core main equipment for large-scale key projects.
