Product Description
The Anti-Wind Single Girder Truss Gantry Crane is engineered for extreme outdoor environments where high winds compromise conventional lifting systems. Its defining truss-style main girder combines open-lattice steel framework with triangular reinforcements, achieving 40% lower wind resistance than solid-web girders while maintaining superior rigidity. Engineered for capacities of 5-32 tons and spans up to 35 meters, the crane's lightweight yet robust structure minimizes deadweight without sacrificing load stability, reducing foundation requirements by up to 25%.
Critical wind-resistance systems include automated rail clamps that lock the crane to ground tracks at wind speeds exceeding 20 m/s, paired with electromagnetic wheel brakes for immediate motion cessation. Optional anemometers integrate with the control system to trigger alarms and progressively restrict operations as wind intensity increases. The anti-sway mechanism, enhanced by variable frequency drives (VFD), ensures precise load positioning even during gusty conditions-crucial for handling sensitive cargo like wind turbine blades or prefabricated bridge segments.
Cost-effectiveness stems from simplified installation-bolted connections allow on-site assembly in 48-72 hours-and 30% lower energy consumption due to reduced structural mass. Remote radio controls with encrypted signals enable operators to manage lifts from safe distances during storms.
This crane represents an optimal synergy of aerodynamics and rugged engineering, delivering uncompromised safety in sectors where wind challenges conventional lifting. Its truss-optimized single girder design balances payload capacity, environmental resilience, and operational reliability for critical outdoor material handling.
Application Scenarios
1:Offshore Wind Farm Installation
Precisely positions turbine blades and nacelles in extreme coastal winds during renewable energy projects.
2:Port Container Handling
Securely moves shipping containers during storms where standard cranes risk wind-induced sway.
3:Bridge Construction
Lifts prefabricated concrete segments and steel frameworks in exposed river/canyon sites.
4:Steel Mill Logistics
Transports hot steel coils (20-32T) through open-yard wind corridors.
5:Shipyard Component Assembly
Installs ship hull sections and engine modules in coastal gust conditions.
6:Power Substation Maintenance
Replaces transformers (15-25T) in grid facilities with strict anti-wind safety protocols.
7:Mining Equipment Transport
Handles oversized crushers and conveyors in mountainous areas prone to crosswinds.
Our Advantages
1:40% Lower Wind Load Resistance
Open-lattice truss design slashes wind pressure impact vs. solid girders (per ISO 4302 wind load calculations ≤750 N/m²).
2:Auto Lockdown at 18 m/s Gusts
Integrated anemometer triggers rail clamps + electromagnetic wheel brakes within 0.5 seconds of exceeding safety thresholds.
3:30% Reduced Structural Weight
High-strength truss geometry cuts deadweight while maintaining rigidity (≤1/1000 span deflection under full load).
4:All-Terrain Adaptability
Hydraulic-adjustable legs compensate for ±150 mm ground variation without auxiliary supports.
5:Corrosion-Proof Durability (IP55/IP56)
Hot-dip galvanized truss joints + sealed electrical components withstand salt spray, sandstorms, and -25°C to +50°C extremes.
6:VFD-Enhanced Sway Control (±50mm precision)
Variable Frequency Drives minimize load swing during 15 m/s crosswinds - critical for delicate cargo like turbine blades.
7:Modular Rapid Deployment (≤72hr assembly)
Bolt-together truss sections and pre-tested wiring harnesses enable on-site commissioning in half the time of box-girder cranes.
Packaging & Shipping
To ensure safe and damage-free transportation, cranes must be securely packaged in heavy-duty wooden crates or steel frames, with critical components like hoists and girders disassembled if oversized and properly strapped. Electrical systems and sensitive parts should be wrapped in waterproof, anti-corrosion materials, while all packages must be clearly labeled with weight, center of gravity, and lifting points. During transit, components must be firmly fastened using chains or straps to prevent shifting, with special attention given to corrosion protection for sea freight and route planning for oversized shipments. These measures guarantee that cranes arrive in optimal condition for assembly and operation.
