Internal Climbing Tower Crane

Core structure composition

 

 

The inner climbing tower crane is mainly composed of the following three parts:

Tower frame system: Usually secured with high-strength bolts, it is made up of standard, reinforcing, and base sections. On the exterior of the regular section, step pieces with slots for fastening during climbing are fitted.
Load-bearing system: It consists of primary load-bearing beams, integrated components, and secondary steel beams for a supporting framework. The primary beam is secured to the core tube shear wall with anchor plate bolts, and the secondary beam is linked horizontally to form a grid support system that can hold the entire weight of the equipment.
The climbing mechanism is made up of hydraulic lifting systems, inner climbing frames, and telescopic supports. The lifting components are pushed by hydraulic cylinders to achieve the equipment's alternating climbing movements.

 

 

Extremely good space adaptability: Because the equipment is located inside the building rather than on exterior construction sites, it can reduce the floor area of standard tower cranes by up to 40%, which makes it ideal for urban expansion projects with small sites.

There are two benefits to construction efficiency and cost: foundation investment expenses are reduced because there is no need to build big concrete foundations or lay external tracks. Additionally, the single climbing time is minimal when alternating climbing operations are used, which greatly speeds up the construction process.

Short tower body and material savings: Because the building supports the foundation, the tower crane's own tower body is comparatively short (usually approximately 30 meters), with less wind load, a low initial expenditure, and increasing economic benefits as the building height increases.

Application Scope: Frequently utilized in complex construction projects with constrained space, dense building clusters in urban core locations, and extremely tall buildings.

Structural Reinforcement Requirements: Prior to construction, local reinforcement of the building structure is necessary to withstand the construction loads since the building bears all loads.

Operation and Demolition Restrictions: Because it is situated inside the building, the driver must frequently rely on signal commands to observe the entire lifting process; the dismantling procedure following construction is rather complicated and typically necessitates the installation of auxiliary lifting equipment on the roof to finish the dismantling operation.
