Tower Crane Climbing Frame

Tower Crane Climbing Frame is the core component of the tower crane self-lifting system, which is used to jack the tower section by section to fit the building height. Its design includes a guide structure and an anti-overturning device to ensure a smooth and safe jacking process, which can withstand the dynamic load of construction, and it is necessary to regularly check the bolt tightening and hydraulic system status to ensure the stability of high-altitude work.

 

 

1. Super dynamic bearing capacity to ensure the safety of extreme working conditions

The climbing frame is made of Q690E ultra-high-strength alloy steel (in line with GB/T 1591 standard), and the key pressure-bearing parts are formed by multi-directional isothermal die forging process to eliminate the internal grain boundary defects of the material, with a tensile strength of 850MPa and a shear bearing capacity of more than 750kN.

Key figures:

Single-point ultimate load: 3,800kN (TUV certified, safety factor 2.0 times)

Lateral impact resistance: ≥900kN (simulated magnitude 9 earthquake test)

Key Benefits:

It supports the continuous climbing of super high-rise buildings above 400 meters (a single climbing height of 20 meters) to avoid the risk of tower crane tilting caused by structural deformation.

The 1.8x dynamic shock test (simulating strong winds and instantaneous load shocks) ensures absolute safety under extreme conditions.

 

2. Modular quick-assembly design, climbing efficiency increased by 80%

The climbing frame adopts a split modular structure, and all components are pre-installed with high-precision positioning pins and 12.9-grade Dacromet bolts, and the on-site assembly time is shortened by 80% compared with the traditional welded type.

Innovative Design:

Laser calibration guide trough: the machining accuracy is ±0.05mm, which ensures seamless docking with the standard section.

Hydraulic synchronous locking system: the single locking time is ≤ 15 seconds, reducing the risk of high-altitude manpower operation.

Key Benefits:

The single climb operation time has been reduced from 10 hours to 2 hours, and the labor cost has been reduced by 65%.

It supports repeated disassembly and rapid reorganization, and adapts to the needs of multi-site circulation projects.

 

3. Anti-fatigue and corrosion-resistant technology, the service life is extended to 30 years

In view of high-frequency climbing and harsh environments, the climbing frame adopts surface shot peening reinforcement + arc spraying zinc-aluminum alloy (thickness ≥ 200μm), and has passed strict tests:

Salt spray test: 5,000 hours without red rust (ASTM B117, 3 times more than the industry standard)

Cyclic load test: 0.1 mm crack propagation ±< 1,500 kN alternating load after 1,000,000 cycles (ISO 12107 standard)

Low temperature toughness: impact energy at -50°C≥60J (GOST R certification)

Key Benefits:

It is suitable for high salt spray and strong acid and alkali environments such as offshore platforms and chemical parks, and the anti-corrosion life is ≥ 30 years.

The plating has a maintenance-free interval of up to 10 years, reducing downtime costs.

 

4. Intelligent safety control system (standard)

Integrate industrial-grade PLC control module and multispectral sensor network to monitor climb attitude, load distribution and structural health status in real time.

Core Functions:

Millimeter-level deviation correction: When the offset is > 1mm, the system automatically adjusts the pressure of the hydraulic cylinder with an accuracy of ±0.5mm.

Multi-level security protection:

Immediately lock the climb action when overloaded by 110%.

Forced cooling is triggered > hydraulic oil temperature of 75°C.

Emergency braking is activated when the structural stress exceeds the limit.

Data management in the cloud: Generate a 3D digital twin of the climbing process and support the ISO 55000 asset management standard.

Key Benefits:

The rate of human error is reduced by 95%, and the risk of accidents is close to zero.

The climbing verticality error is <1/1000, which meets the requirements of super high-rise construction.

 

5. Customized solutions for harsh environments
