Weihua single girder bridge cranes offer a robust, cost-effective, and space-saving solution for diverse material handling needs across industries. Designed for precision and reliability, these cranes efficiently transport loads within rectangular work areas defined by building structures or supporting runways. Ideal for workshops, warehouses, assembly lines, and light to medium-duty applications.
1. Optimized Design & Space Efficiency:
Single Box Girder Construction: Features a sturdy, welded box-section main girder, ensuring strength with minimal self-weight and reduced headroom requirements – perfect for facilities with height limitations.
Compact End Carriages: Engineered for smooth travel along runways with minimal overhang, maximizing usable floor space beneath the crane.
2. Superior Performance & Control:
Electric Hoist Integration: Typically equipped with Weihua’s reliable wire rope electric hoist (LH type or similar), offering smooth lifting and traversing motions. Options for chain hoists available.
Precise Travel Mechanisms: High-efficiency travel drives for both the crane bridge (long travel) and hoist trolley (cross travel), ensuring accurate load positioning and smooth operation.
Variable Speed Control (Optional): Available with frequency control (VF drives) for exceptionally smooth starts/stops, precise load handling, and reduced swing.
3. Enhanced Safety & Reliability:
Rigorous Construction: Manufactured under strict quality control (ISO 9001 certified), utilizing high-grade steel and precision welding.
Comprehensive Safety Devices: Standard features include overload limiters, emergency stop buttons, limit switches for all travel directions (up/down, left/right, forward/back), safety catches on hooks, and bumpers.
Robust Electrical System: IP54 or higher protected components ensure reliable operation in industrial environments. Compliant with international electrical safety standards.
CE Certification: Meets essential EU health, sự an toàn, and environmental requirements.
4. Durability & Low Maintenance:
High-Quality Components: Utilizes premium bearings, sealed gearboxes, and durable wheels for extended service life.
Corrosion Protection: High-quality paint system (sandblasting, primer, topcoat) offers excellent corrosion resistance suitable for standard industrial environments.
Easy Access for Maintenance: Designed with accessibility in mind for routine inspections and servicing.
5. Operational Flexibility:
Wide Capacity Range: Available from 1 ton to 20 tons standard, with higher capacities possible via custom engineering.
Broad Span Coverage: Capable of handling spans typically ranging from 5 meters to over 30 meters.
Customizable Options: Hoist type (rope/chain), lifting height, speed requirements, control systems (pendant, radio remote, cabin), lighting, special environmental protection (foundry duty, explosion-proof), and runway solutions.
6. Smart Features (Optional):
Weihua Winch Smart Monitoring: Optional IoT sensors and monitoring systems provide real-time data on load weight, operating status, usage hours, and predictive maintenance alerts.

1. Optimized Power Consumption: Equipped with high-efficiency motors (IE3/IE4 class) and regenerative drives (không bắt buộc), reducing energy use by up to 30% versus conventional systems.
2. Low Noise Operation: Precision-engineered gearboxes and vibration-dampened components ensure noise levels ≤75 dB(A), ideal for noise-sensitive environments.
3. Adaptive Speed Control: VFD options enable soft acceleration/deceleration, minimizing load swing and structural stress while enhancing positioning accuracy (±1 mm).
Optional IoT integration transforms your crane into a data-driven asset:
Real-Time Monitoring: Track load weight, operating hours, travel distance, and motor temperature via cloud platform or mobile app.
Predictive Maintenance: AI algorithms analyze wear patterns (brakes, bearings, wires) and issue alerts before failures occur, cutting downtime by 40%.
Collision Avoidance: Laser/ultrasonic sensors detect obstacles in travel paths, triggering automatic slowdowns or stops.
Usage Analytics: Generate reports on crane utilization, peak loads, and operator efficiency for process optimization.
Weihua tailors cranes to withstand extreme conditions:
| Variant | Key Enhancements | Applications |
| Foundry Duty | Heat shields (up to 180°C), sealed wiring (IP65), insulated hoist | Steel mills, casting shops |
| Explosion-Proof | ATEX/IECEx-certified components, spark-resistant materials | Chemical plants, refineries |
| Corrosion-Resistant | Duplex stainless steel components, epoxy coating (300μm) | Ports, wastewater treatment |
| Low-Temperature | Arctic-grade lubrication, -40°C rated electronics | Cold storage, polar operations |
When a Weihua Single Girder Crane is optimal:
| Factor | Single Girder | Double Girder |
| Cost | 20-35% lower CAPEX | Higher initial investment |
| Headroom | Saves 300-800mm vertical space | Requires greater building height |
| Capacity | Ideal for ≤20 tons | Recommended for >20 tons |
| Installation Time | 30-50% faster | Complex assembly |
| Maintenance | Easier access to components | More components to service |
Note: Weihua offers both solutions – consult our engineers for a fit assessment.
Weihua single girder bridge cranes represent the smart choice for efficient, safe, and economical overhead lifting where double girder capacity is not required. Contact Weihua today to discuss your specific requirements and get a tailored solution.
