Simple Lifting Beam + Positioning Slings: The "Steel Backbone" of the Cross-Sea Bridge is Precisely Positioned!
Take a look at this stunning cross-sea bridge construction site! Simple lifting beams paired with position-limiting slings steadily support massive steel beam sections:
✅ The beams utilize a mechanically optimized structure to evenly distribute the load of the massive steel beams, ensuring they maintain a horizontal and stable position even in complex wind-swept environments.
✅ The position-limiting slings act as "smart anchor points," precisely locking the beam sections in place and completely eliminating lateral movement and sway during installation, ensuring seamless alignment at high altitude.
✅ The multi-point design and adaptable flexible slings perfectly accommodate the complex shape of the bridge's steel structure. From factory prefabrication to precise assembly at sea, the entire process is efficient and safe, building the "steel backbone" of this mega-project and providing a reliable foundation for the lifting process.
The core advantages of the simple lifting beam, combined with the position-limiting sling, lie in four key areas: load-bearing capacity, precision, adaptability, and safety.
1.Uniform load-bearing and stable anti-swaying: The beam's mechanically optimized structure (multiple lifting points/optimized load distribution) evenly distributes the load on large-tonnage components (such as bridge steel box girders and heavy steel structures), avoiding localized stress concentrations. The position-limiting sling precisely limits the movement of the hoisted object, ensuring stability even under complex working conditions such as offshore wind loads and high-altitude disturbances, eliminating the risk of sway and lateral movement.
2.High-precision alignment improves assembly efficiency: The position-limiting sling acts as a "space anchor," precisely locking the component position and significantly reducing alignment errors during high-altitude/offshore assembly. This allows for seamless and quick connection between steel components, reduces repeated adjustments, and significantly improves assembly efficiency for mega-projects such as cross-sea bridges and large stadiums. Flexible adaptability across multiple scenarios allows for handling heavy components of varying shapes (special-shaped steel structures, long-span beam sections, etc.). The load distribution of the lifting beam can be adjusted based on component size and weight. The flexible positioning slings can conform to component surfaces while accommodating complex construction environments such as offshore and mountainous terrain, meeting the lifting needs of various applications, including infrastructure, bridges, and industrial plants.
3.Safety protection prevents damage to the flexible contact of the positioning slings and prevents rigid collisions between the lifting device and the component surface, protecting the appearance and structural integrity of steel structures and precision equipment. The entire system features high safety redundancy, minimizing risks such as slippage and breakage during heavy-load lifting, fully ensuring the safety of equipment and construction personnel.
1. Bridge Engineering
Sea-crossing/river-crossing bridges: Large steel box girders and truss girders, such as those shown in the image, are hoisted and assembled at sea and high altitude. Hoisting beams distribute large loads, resisting wind and current disturbances. Positioning straps precisely lock the beams into position, achieving millimeter-level alignment between the beams and piers/existing beam sections. Typical examples include the erection of steel beams for the Hong Kong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Link.
Urban viaducts/interchanges: Precast concrete box girders and steel-concrete composite beams are hoisted on land. In complex urban traffic conditions, positioning straps prevent beam sway and damage to surrounding structures. Hoisting beams ensure stable lifting of heavy loads, accelerating the construction of the bridge structure.
2. Industrial and Equipment Installation
Heavy-duty plant construction: Hoisting large-span steel roof trusses and massive columns for metallurgical and chemical plants. Hoisting beams adapt to the loads of the special-shaped steel structures, while position-limiting straps stabilize the high-altitude assembly, preventing deformation and facilitating rapid roofing. Large Equipment Installation: Lifting heavy equipment such as power plant turbines and petrochemical reactor towers. Limiting slings conform to the equipment surface to prevent scratches, and lifting beams evenly distribute the load, ensuring precise positioning of 100-ton equipment on pre-embedded foundations.
3. Venues and Super-High-Rise Buildings
Large Venues: Segmented lifting of large-span trusses (such as bird's nest-style roofs) in stadiums and exhibition centers. Lifting beams adapt to special-shaped components, and limiting slings control their spatial posture, ensuring high-altitude assembly precision and facilitating the formation of complex venue designs.
Super-High-Rise Buildings: Lifting steel columns and giant truss layers in skyscraper cores. Limiting slings suppress component sway in strong winds at high altitudes, while lifting beams stabilize loads, improving the accuracy and efficiency of super-high-rise steel structure installation.
4. Water Conservancy and Energy Engineering
Hydropower Dams: Lifting giant precast concrete blocks and gate steel structures. Lifting beams are corrosion-resistant and load-resistant in humid conditions near the water. Limiting slings precisely control component positioning in the dam's reserved grooves, ensuring the quality of water conservancy facility installation. Wind power projects: Onshore and offshore wind turbine tower and nacelle installation. In offshore applications, restraining straps stabilize the equipment against waves and wind, while lifting beams support heavy loads, facilitating precise assembly of wind turbine equipment in complex environments.
