Luffing Jib Tower Crane

 

- Eliminating collision risks with adjacent structures and other cranes

- Meeting heavy-load lifting requirements (exceeding hammerhead cranes' capacity)

 

 

1. Hydraulic climbing drive unit

2. Climbing frame assembly

3. Modular climbing ladder system

 

The climbing frame mounts at the tower base, bolted to standard mast sections. Suspended from C-beams, the ladder system enables full-crane elevation through alternating extension/retraction of the frame's lifting beams. Maximum climbing height is determined by the installation elevation of the internal climbing support system. Modular ladder components allow length customization for varying climbing distances.

 

 

(1)The lifting capacity of super high-rise buildings is generally made of steel or steel, concrete composite structure, the weight of the hoisting unit is greatly increased, and the special-shaped and composite structure reaches more than 80 tons. Large boom towers are equipped with heavy-duty main hoisting systems, typically with a maximum lifting capacity of 32 to 100 tons.

(2)Due to the use of a special climbing system, the crane can climb with the overall building structure, and the lifting height is greatly improved, and a large number of tower body standard sections are also saved.

(3)The lifting speed is fast, the lifting structure has high power, especially the self-provided internal combustion engine driving scheme, and the lifting speed with load exceeds 100m/min.

(4)Coverage area: The boom tower crane is arranged inside the super high-rise structure, with large coverage and full energy efficiency.

 

 

Spatial adaptability: The boom of the boom tower crane can adjust the operating range by luffing (changing the elevation angle), without relying on the horizontal moving trolley, effectively avoiding collision with the surrounding buildings or tower crane boom. This property is critical in dense urban environments.

Lifting capacity and height advantages: The lifting capacity of the boom tower crane is dynamically adjusted with the operating radius, which is suitable for the lifting of large components of super high-rise buildings, such as steel columns and giant trusses. It adopts internal climbing installation, which can climb with the height of the building, break through the limitation of independent height, and is more suitable for super high-rise buildings above 300 meters.

Wind stability: The boom of the boom tower crane can be retracted to a small elevation angle, reducing the wind area and reducing the impact of high-altitude wind load. The horizontal arm of the flat-top tower crane is easy to swing under strong winds, which has potential safety hazards.

Multi-tower collaborative operation: When multiple tower cranes are intensively arranged, the boom tower crane can avoid mutual interference by adjusting the angle of the boom, while the horizontal arm of the flat-top tower crane needs to be strictly staggered in height to limit the flexibility of the layout.

Cost and maintenance: High acquisition and installation costs, complex maintenance. The cost is low and the degree of standardization is high.

Operation efficiency: the angle of the boom needs to be adjusted for luffing, and the hoisting positioning is slightly slower. The trolley moves horizontally and has a fast positioning speed, which is suitable for frequent lifting of lightweight materials.
