A single-girder underhung bridge crane is a compact lifting system designed to operate on the underside of building structures. It typically runs on I-beam rails suspended from steel frameworks or prefabricated roof beams, and its overall structure is similar to that of a single-girder electric overhead crane. Because the crane is supported by the building roof, higher requirements are placed on the roof’s load-bearing capacity. For this reason, underhung bridge cranes are mainly used for light-duty lifting, with typical capacities up to 10 tons and spans ranging from 3 to 16 meters. Both capacity and span can be customized to suit specific site conditions.
The crane’s travelling mechanism is integrated with the electric hoist system, allowing smooth and stable movement along the suspended runway. The main girder is supported by suspension beams, ensuring reliable lifting and precise positioning of loads. This design allows the crane to operate efficiently in confined spaces where floor-mounted or top-running cranes are not practical.
Single girder underhung bridge cranes are especially suitable for workshops, warehouses, and production areas with limited headroom. By utilizing ceiling space, they maximize usable floor area and improve material flow. With their lightweight structure, flexible layout options, and cost-effective design, underhung bridge cranes provide an ideal lifting solution for small to medium load handling in low-clearance industrial environments.
Product Advantages
♦Space-Saving Design: The underhung design allows the crane to operate directly along the ceiling, saving valuable floor space. This is particularly beneficial in buildings with low headroom or limited vertical clearance, maximizing the use of available space.
♦Efficient Load Handling: Ideal for light to medium-duty applications, the underhung bridge crane offers lifting capacities from 1 ton to 10 tons, making it perfect for use in warehouses, manufacturing facilities, and assembly lines where efficient material handling is essential.
♦Smooth and Quiet Operation: Equipped with precision wheels and high-quality bearings, the crane operates smoothly and quietly, minimizing noise pollution in the workplace. This contributes to a more comfortable and productive working environment.
♦Heavy-Duty End Trucks: The crane features robust end trucks that ensure stable and reliable movement, even under maximum load conditions. These durable end trucks improve both the crane’s lifespan and its overall safety performance.
♦Easy Installation: The single girder underhung crane is designed for quick and easy installation, significantly reducing setup time and associated costs. This makes it an ideal solution for projects with tight timelines or budget constraints.
♦Customizable Features: This crane is highly customizable, offering flexibility in terms of span, lifting height, and control systems. It can be tailored to meet the unique requirements of any facility or operation.
♦Durability and Reliability: Constructed from high-strength steel, the crane is built to last. It is designed for long-term performance, even in demanding environments. Additionally, it includes essential safety features such as overload protection and limit switches for safe operation.
♦Energy Efficiency: Designed with energy-efficient components, the underhung bridge crane minimizes power consumption, lowering operational costs and reducing its environmental impact.
Applications
♦Workshops & Manufacturing Facilities: Light duty bridge cranes are widely used in workshops and manufacturing plants to lift raw materials, components, and semi-finished products. Their ceiling-mounted design makes them especially suitable for tight production spaces where floor-mounted equipment is not practical.
♦Warehouse & Logistics Operations: In warehouses and distribution centers, these cranes help handle goods, pallets, and packaged items efficiently. They improve material flow, reduce manual handling, and optimize storage operations without occupying valuable floor space.
♦Assembly Lines: Light duty bridge cranes play an important role in assembly lines by assisting with the lifting and positioning of parts at different workstations. Their smooth and precise operation supports higher assembly accuracy and productivity.
♦Repair & Maintenance Facilities: Ideal for repair shops and maintenance areas, these cranes are used to lift, hold, or reposition heavy machinery parts during inspection, servicing, or repair tasks, ensuring safer and more efficient workflows.
♦Automotive Industry: In automotive manufacturing and assembly plants, light duty bridge cranes are commonly used to handle engines, components, and tooling, supporting streamlined production processes.
♦Construction & Confined Sites: Light duty bridge cranes assist in lifting building materials and equipment in areas with limited space or headroom, offering a practical solution for constrained construction environments.
Thanks to their compact structure, flexible operation, and efficient use of space, single girder underhung bridge cranes are a reliable lifting solution across multiple industries, enhancing productivity while maintaining safety and cost efficiency.
