Inner Climbing Tower Crane

 

In-climb tower crane is a special tower crane installed inside a building, which is mainly used for the construction of high-rise buildings.

 

 

The internal climbing tower crane is generally arranged in the building, so the amplitude of the tower crane can be smaller, that is, the boom can be shortened, and does not occupy the peripheral space of the building; Because it is used to climb upwards by using buildings, the climbing height is not limited, and the tower body is much shorter. Therefore, the overall structure is light and the cost is low.

 

The principle of climbing outlines the core: the climbing device (climbing frame) is used to jack the upper part of the tower crane as a whole for a distance, and then insert or remove the standard section at the gap of the jacking, so as to change the overall height of the tower crane.

 

 

1. Tower body (standard section)

The tower crane is connected by multiple standardized tower body segments (standard sections). Each section is usually the same length and can be connected to adjacent standard sections by means of bolts or pins.

2. The upper part of the slewing tower crane includes a tower cap, a slewing mechanism, a lifting arm and a balance arm, etc., which is responsible for hoisting operations and is the main operating mechanism when the tower crane works.

3. Climbing device (climbing frame, jacking frame)

The climbing device is usually installed between the upper part of the tower crane and the tower body, and contains hydraulic cylinders, guide rails, wedges and other mechanical structures. It is responsible for jacking or supporting the superstructure, allowing the tower crane to "look up" and leave room for installation when a new standard section is added.

4. Foundation or attachment support

The lower part of the tower crane is fixed by the foundation, or the attachment support connected with the building is arranged in a plurality of places after a certain height, so as to ensure the overall stability of the tower crane.

 

 

● Optimized Space Utilization:

Installed within building structures (e.g., elevator shafts or stairwells), internally climbing cranes eliminate external site occupancy - particularly advantageous in space-constrained urban environments.

● High Cost Efficiency:

Requiring neither additional tracks nor dedicated foundations nor complex auxiliary components, these cranes significantly reduce equipment costs and maintenance complexity.

● Operational Convenience:

Immune to adverse weather conditions, they ensure continuous construction progress while minimizing disturbances to surrounding areas.

● Enhanced Safety:

The internal configuration inherently avoids collision risks with external building structures, substantially elevating worksite safety. .

 

 

1. The tower crane is arranged in the middle of the building (installed in the indoor elevator shaft), which is especially suitable for use in the downtown area where the construction site is small.
2. The effective construction coverage area of the hanging object is large, which can give full play to the overweight capacity of the tower crane and improve the work efficiency of the tower crane.
3. The cost of the whole machinery is small.

 

 

The internal climbing tower crane is especially suitable for those occasions where the external construction site is limited or there are special building structure requirements, such as the construction of high-rise buildings, the transformation of urban infrastructure, etc. In these environments, in-climb tower cranes can effectively improve construction efficiency and safety while reducing the impact on the surrounding environment. The in-climb tower crane is an efficient, economical and safe construction tool, which is suitable for a variety of complex building construction environments. At the same time, its use also requires attention to the potential burden on the building and the specific installation and demolition requirements.
