What Is an Underhung Overhead Crane?

Date: 2024-02-23 Share:

An underhung overhead crane, also known as a suspension crane, is a special type of lifting equipment. The main difference between underhung overhead cranes and other overhead cranes is the way the tracks and cranes are arranged.


The rails of an underhung overhead crane are usually mounted on the top or superstructure of the plant, and the crane itself is suspended below these rails. Its lifting trolley and hook and other working mechanisms are located below the overhead, hence the name “under-hung”. Due to their structural characteristics, underhung overhead cranes usually have a low building height and are suitable for height-restricted spaces.


As a result, underhung overhead cranes may be more flexible and efficient for certain work environments and layouts.

Main Features of Underhung Overhead Crane


Firstly, the underhung overhead crane is compact in design, it occupies a small footprint and can fit into tight spaces without compromising lifting performance. And the underhung overhead crane is equipped with a low headroom crane specifically designed for spaces with restricted installation heights.

Secondly, the underhung overhead crane‘s operation is designed to be quiet, minimizing noise pollution in the working environment. It incorporates a monorail end frame to ensure smooth running along the track.

In addition, the underhung overhead crane has a low deadweight and lightweight structure that minimizes loads on the supporting structure and is suitable for weaker or older buildings. Its simple design and simple components make installation and routine maintenance quick and easy.



Application Industry


Underhung overhead cranes are widely used in a variety of industrial situations, especially those where space is limited or where efficient material handling is required. In some cases, where the height limitations of the plant or other structural constraints make it impossible to install a conventional top-mounted overhead traveling crane, the underhung overhead crane becomes an ideal alternative.

The underhung overhead crane is ideal for situations where a conventional overhead crane cannot be installed due to height restrictions or the need for a lightweight lifting solution. Its portability and adaptability make it ideal for maintenance operations, production lines and other industrial environments where space is at a premium.

In addition, the underhung overhead crane is a unique lifting device designed specifically for workshops that lack traditional overhead support structures or bull legs. Their primary use is for low headroom environments, light lifting loads and situations where smaller lifting capacities are sufficient.

Below are some of the main industries where underhung overhead cranes are commonly used:

Aviation and Aircraft Maintenance: Due to the height of aircraft, vertical space in hangars is often limited. Underhung overhead cranes are ideal for lifting and maneuvering aircraft parts, tools and equipment in these limited spaces.

Automotive Industry: Underhung overhead cranes are used in automotive manufacturing and repair shops to move components, assemble parts and perform maintenance tasks efficiently.

General Manufacturing: Manufacturers in a wide range of industries such as electronics, machinery and furniture often require lifting equipment to move parts and materials. Underhung overhead cranes are suitable for these light-lifting tasks.

Warehouses and Distribution Centres: In warehouses and distribution centers, where space is often limited, overhead cranes can efficiently handle pallets, cartons and other materials without taking up additional vertical space.

Construction: On construction sites where there are temporary buildings or limited access areas, underhung overhead cranes can be used to lift materials, equipment and tools.

Maintenance and Repair Workshops: Facilities such as machine shops, electrical repair shops and other maintenance-intensive environments benefit from overhead cranes for lifting heavy equipment and components.

Rail and Transport: In railway workshops and transport facilities, overhead traveling cranes are used to maintain and repair locomotives, wagons and other railway equipment.

Shipbuilding and Marine: Shipyards and ship repair facilities often have limited headroom due to the size and height of ships. Underhung overhead cranes are suitable for lifting and installing components, performing maintenance and assisting in shipbuilding activities.


In summary, underhung overhead cranes are adaptable and compact, making them a valuable asset in a variety of industries where space is limited or lifting requirements are not too high or too low. These cranes contribute significantly to the efficiency and safety of various lifting operations.

Safety Precautions


Safety is of paramount importance when operating any lifting equipment. Underhung overhead cranes should only be operated by trained personnel who are familiar with their operating procedures and safety guidelines. Regular maintenance checks should be carried out to ensure that the crane is kept in a safe working condition.


In conclusion, the underhung overhead crane is an efficient material handling equipment suitable for specific environments and needs. When selecting and using it, its characteristic advantages should be fully considered to ensure that it can maximize its effectiveness and guarantee work safety.
