Common types:
♦ Three-in-one motor
“Three-in-one” drive mode: The motor, reducer and brake are combined into one drive device. It has the advantages of compact structure, easy installation, high transmission efficiency and low noise.
Double Girder Bridge Crane：An Efficient Solution for Material Handling
♦ Overview
Double girder overhead cranes are robust industrial lifting solutions designed for heavy-duty applications, offering superior load capacity, stability, and operational efficiency. From a buyer’s perspective, understanding their technical specifications, advantages, and customization options is crucial to making an informed purchasing decision.
♦ Technical Specifications
Load Capacity：Ranges from 5 tons to 800+ tons, with specialized models handling up to 1,500 tons for extreme industrial demands.
Span：Typically 10.5–40.5 meters, with some models extending to 42 meters for large workshops or warehouses.
Lifting Speed：Varies between 0.63–63 m/min for precision and efficiency, depending on load requirements.
Work Duty Class：Compliant with A3–A8 standards (FEM/DIN), ensuring reliability in high-intensity operations like steel mills or mining.
Design：Features two parallel girders for enhanced stability, with options for top-running or under-running trolleys and modular components for adaptability.
♦ Key Advantages
Cost Efficiency：Reduces structural demands on buildings due to lower wheel pressure (up to 35% reduction) and lightweight European designs (15–30% lighter), minimizing construction costs.
Customization：Available in configurations like LH-type hoist trolleys or QD-type winch trolleys, with options for explosion-proof, insulated, or automated systems for hazardous environments.
Energy Savings：Advanced motor systems (e.g., SEW or ABB) and optimized power consumption reduce operational costs.
Safety and Compliance：Meets CE, FEM, and ISO standards, with features like dual braking systems, overload protection, and explosion-proof certifications for high-risk industries.
♦ Applications
Heavy Industries: Steel production, mining, and foundries, where 150-ton cranes handle molten metal or large-scale forging.
Logistics and Warehousing: High-speed trolleys (up to 110 m/min) for rapid material transport in large facilities.
Specialized Environments: Includes insulated cranes for aluminum smelters, magnetic systemsfor steel handling, and low-headroom designs for space-constrained areas.
♦ Why Choose Double Girder Cranes?
Compared to single-girder models, double girder cranes excel in heavy-load handling, longer spans, and higher lifting heights (up to 60 meters). Their durability and adaptability make them ideal for industries prioritizing productivity and safety.
