Overview

An underhung bridge crane, also known as an under-running crane, is a versatile lifting solution designed to maximize workspace efficiency. Unlike top-running cranes, this system is suspended directly from the buildings overhead structure, eliminating the need for additional floor-mounted supports or columns. This feature makes it an ideal choice for facilities where floor space is limited or where maintaining a clear working area is essential.

In an underhung system, the end trucks travel along the lower flange of the runway beams, allowing smooth and precise crane movement. These runway beams form the supporting structure that guides the cranes operation. Compared to top-running bridge cranes, underhung bridge cranes are generally lighter in construction, yet they provide excellent lifting capacity and reliability for medium-duty applications.

Underhung bridge cranes are widely used in workshops, assembly lines, and production environments where material handling efficiency and flexibility are priorities. They can also be easily integrated into existing structures, reducing installation costs and downtime. With their compact design, quiet operation, and efficient use of space, underhung bridge cranes offer a cost-effective and practical lifting solution for a wide range of industrial applications.

Applications

Manufacturing and Assembly Lines: Underhung bridge cranes play a vital role in manufacturing and assembly operations that demand precise and efficient part handling. In industries such as automotive, electronics, and precision engineering, these cranes enable smooth transfer of both delicate and heavy components between workstations. Their ability to operate in restricted or low-clearance areas makes them ideal for complex assembly environments, reducing the risk of product damage while improving overall production efficiency.

Warehousing and Logistics: In warehousing and logistics facilities where space optimization is essential, underhung cranes provide an effective material-handling solution. Suspended from the ceiling structure, they eliminate the need for support columns, freeing valuable floor space for storage and equipment movement. Their compact design allows unobstructed operation of forklifts and conveyors, ensuring a seamless and organized workflow.

Food and Beverage Processing: For industries with strict hygiene requirements, such as food and beverage processing, underhung bridge cranes can be manufactured using stainless steel or other corrosion-resistant materials. Their smooth surfaces and enclosed components help prevent contamination, supporting compliance with sanitation standards while maintaining efficient movement of raw materials and finished goods.

Aerospace and Heavy Machinery: Underhung cranes are also widely used in aerospace, defense, and heavy machinery production, where handling large, irregularly shaped, and sensitive components demands precision and control. The smooth, stable motion and accurate load positioning of underhung bridge cranes reduce handling risks and protect high-value equipment, ensuring safety and reliability in every lift.

FAQ

1. What is the maximum weight an underhung bridge crane can lift?

Underhung bridge cranes are typically designed to handle loads ranging from 1 ton to over 20 tons, depending on the girder configuration, hoist capacity, and structural design. For unique applications, customized lifting capacities can be engineered to meet specific operational requirements.

2. Can underhung cranes be retrofitted into existing facilities?

Yes. Thanks to their modular and lightweight design, underhung bridge cranes can be easily integrated into existing buildings without major structural modifications. This makes them a cost-effective choice for upgrading material-handling systems in older or space-limited facilities.

3. How do underhung cranes improve energy efficiency?

Underhung cranes are built with lightweight components and low-friction mechanisms, resulting in smoother motion and reduced power consumption. This energy-efficient operation helps lower overall maintenance costs and improves long-term sustainability.

4. Are underhung bridge cranes suitable for outdoor use?

While primarily designed for indoor environments, underhung cranes can be equipped with weatherproof coatings, sealed electrical systems, and corrosion-resistant materials to perform reliably in outdoor or semi-outdoor conditions.

5. What industries benefit most from underhung cranes?

They are ideal for manufacturing, warehousing, automotive, food processing, and aerospace sectors, where precise load control and space efficiency are critical.

6. Can underhung cranes operate on curved runways?

Yes. Their flexible track systems can be designed with curves or switches, allowing the crane to cover complex production layouts efficiently.

7. What safety features are included?

Modern underhung cranes come with overload protection, emergency stop systems, anti-collision devices, and smooth-start drives, ensuring safe and reliable operation in all working environments.
