What Are the Application Scenarios of Single Girder Overhead Travelling Crane?
I have been in the crane industry for more than ten years, and I often meet buyers who come up and ask ‘can I use a single girder crane’ without telling them their own workshop conditions and lifting needs – in fact, single girder overhead travelling crane is widely used, but it is not suitable for all scenarios. In fact, single girder overhead travelling crane (single girder overhead crane) is widely used, but it is not suitable for all scenarios.Many people try to purchase it blindly because of its cheap and simple structure, but in the end, either the lifting capacity is insufficient, or it conflicts with the workshop space, and the equipment wears out in advance, and we have to spend money on upgrading at a later stage, which is not worth the loss.What we should really ask is not ‘is the single girder crane cheap’, but ‘is it suitable for my work’.

Today, I will combine the daily contact cases – such as many small and medium-sized enterprises choose Henan Mine Crane, its single girder overhead travelling crane series due to strong adaptability, cost-effective, outstanding performance in a number of scenarios – to make it clear to you single girder overhead travelling crane Application scenarios, applicable boundaries, as well as the selection of places to pay attention to, to help you take the road less travelled.
Whether you are a purchaser in a machine shop or a warehouse manager, if you want to understand single girder overhead crane use cases, where to use single girder overhead crane, you will be able to clear your mind after reading this article.
What Is a Single Girder Overhead Travelling Crane?
The core structure of a Single Girder Overhead Travelling Crane is not complicated, so let’s start with a brief description of its main components to make it easier to understand its application scenarios.
The core is the single bridge girder, which is the load-bearing core of the whole equipment, spanning between the rails in the workshop, with a simple appearance, unlike double girder cranes which have two main girders.
The two ends of the main girder are equipped with end carriages / end trucks, the wheels on the end carriages drive the crane to move along the top rail, which is its longitudinal movement mechanism.
Below the main girder hangs an electric hoist (electric hoist), there are two kinds of wire rope hoist and chain hoist, is responsible for the lifting of the material of the core components, but also the most common operation of the whole crane.
In addition, there are cross travel and long travel mechanisms, which are responsible for moving the hoist and the crane itself; the power supply system provides power to the entire equipment, and the control system is divided into two types: pendant and remote control, which are all relatively simple to operate.
How It Works
The logic of its work is very simple and can be understood without too much complex expertise.
The crane itself moves longitudinally along the runway rails at the top of the workshop, covering the entire length of the workshop, while the electric hoist above it moves horizontally along the main beam, covering the width of the workshop.
The hoist’s lifting action, together with the longitudinal and transverse movements, enables the transfer of materials anywhere in the workshop, the core of which is the combination of ‘lifting + panning’ to meet basic lifting requirements.
Why It Is Popular
The single girder overhead travelling crane can be widely used in the industrial sector, the core of which is its several advantages, which just fit the needs of many small and medium-sized enterprises.
Firstly, it is compact, unlike double girder cranes that take up too much space, and is suitable for most standard workshop layouts, especially for old factory buildings where space is tight.
Secondly, the self-weight is light, the load-bearing requirements of the plant is lower, many old workshops do not need additional reinforcement of the track beam, it can be installed and used, saving a reinforcement costs.
The most important thing is cost-effective, for light to medium lifting tasks, its initial investment than double girder crane is quite low, and the later maintenance is also simple, very suitable for small and medium-sized enterprises, ordinary processing plant use – this is also light duty overhead crane applications, it is the most This is the reason why it is the most popular in light duty overhead crane applications, such as Henan Mine Crane’s single girder products, which accurately meets the needs of this type, taking into account the practicality and economy.
Key Characteristics That Determine Application Fit
Single Girder Crane is not universal, its suitability, first of all, depends on the load and operating frequency.
It is mainly suitable for light to medium load lifting, there is no absolute standard for the specific tonnage, it should be combined with the actual project, but most of them are concentrated in the range of 0.5-20 tonnes, more than this range, you need to consider the double girder crane.
Frequency of operation, it is suitable for medium-frequency lifting, such as lifting dozens of times a day, not 24-hour continuous operation of high-intensity operations.
In addition, it is more suitable for standard indoor workshop environment, without extreme high temperature, strong corrosion and other harsh conditions, the cycle of operation is repetitive, but not extremely heavy production cycle.
Building and Layout Advantages
The layout advantages of single girder cranes are obvious for enterprises with limited workshop conditions.
Many old workshops have limited headroom, and the hoist of single girder crane is hung directly under the main beam, unlike double girder cranes with additional bridge structure, which can make better use of the limited headroom to meet the requirements of the lifting height (depending on the configuration of the hoist).
Its wheel pressure is lower than many double girder cranes, which requires less load bearing on the rail beams of the plant, without additional reinforcement, and it is easier to install, and can be directly adapted to many standard factories.
This is why single girder bridge crane for workshop is more widely used than double girder crane in small and medium-sized factories.
Cost and Maintenance Considerations
From the cost point of view, the initial investment of single girder bridge crane is usually lower than double girder bridge crane, which is the reason why many small and medium-sized enterprises prefer it.
Its structure is simple, without complex bridge and transmission mechanism, and it is easy to maintain in the later stage. Maintenance personnel do not need to have a high level of professionalism, and daily inspection, lubrication, and replacement of wearing parts can be completed quickly.
For small and medium-sized enterprises, ordinary manufacturing workshop, its cost-effective just match the demand, do not have to use the large tonnage, high strength performance more money. This

Main Application Scenarios of Single Girder Overhead Travelling Cranes
For example, raw materials, semi-finished products and finished parts in the workshop need to be lifted from the raw material area to the processing machine tools, and then lifted to the finished product area after processing, which can be easily done by single girder crane.
The loading and unloading of machine tools is also inseparable from it, such as large machine tool parts, manual transport is not possible, with a single girder crane lifting to the installation location, both energy-saving and safe.
There are also parts transfer between stations, such as lifting from the stamping station to the assembly station, without manual handling, to reduce labour intensity, but also to avoid material damage.
This type of scene is common in the industry of machinery manufacturing, metal processing, equipment assembly, and various types of general industrial plants, are the main application areas of single girder cranes, Henan Mine Crane’s single girder series of high popularity in these industries, and can be flexibly adapted to the lifting needs of different workshops.
Warehouse and Indoor Logistics Handling
Warehouse and indoor logistics handling is also an important part of single girder EOT crane applications, especially in the field of industrial warehousing.
Palletised goods in warehouses with the right spreader can be lifted by single girder cranes, unloaded from transport vehicles and stacked on shelves, much more efficiently than manual handling.
The storage and transfer of moulds, tools and maintenance parts are also suitable for single girder cranes. For example, large moulds in the workshop warehouse need to be lifted and transported to different production stations, and single girder cranes are flexible in operation and can be accurately positioned.
Why is single girder crane suitable for warehouse scenes? The core is its moderate intensity of operation, most of the lifting in the warehouse is intermittent, not continuous high load; and the indoor environment is stable, there is no bad weather, just fit the characteristics of the single girder crane.
For cost-sensitive warehouses, single girder cranes are also more cost-effective, which is also the warehouse overhead crane single girder popular reasons, Henan Mine cranes for warehouse scenarios, but also can be customised to the lifting height and operating speed, to further enhance the efficiency of logistics transfer.
Assembly and Maintenance Bays
Equipment assembly and maintenance areas, the role of single girder cranes is irreplaceable, especially for cyclical maintenance tasks.
For example, the workshop motors, pumps, gearboxes, the need to dismantle the fault maintenance, most of these components weigh a few tonnes to more than a dozen tonnes, manual transport is simply not possible, single girder cranes can be easily lifted to the maintenance bench.
When installing new equipment, it is also necessary to use single girder cranes to assist in lifting and transporting the equipment parts to the installation location, and cooperate with the workers to complete the assembly, to avoid damage to the parts or injuries caused by manual handling.
This kind of scenario is common in maintenance workshops, power houses, factory maintenance areas, service stations, are mainly cyclical maintenance, not continuous production lifting, just suitable for single girder cranes.
Light Fabrication and Steel Structure Workshops
Light Fabrication and Steel Structure Workshops are also common scenarios for single girder cranes, but attention should be paid to differentiate the intensity of operation.
For example, the handling of steel plates and profiles, the lifting of small steel structure components, and the transfer of semi-finished products between welding and assembly stations, single girder cranes are capable of handling.
Many small steel processing plants, the daily lifting task is not heavy, the load is also moderate, with a single girder crane is just right, do not have to invest in double girder crane high cost.
Here is a special reminder: be sure to assess the actual length of the load, lifting mode and frequency of operation. If it is heavy steel structure processing, large load, frequent operations, you need to choose double girder cranes, single girder cranes can not meet the demand; and small steel structure workshop, choose Henan Mine Crane single girder products, can be a good balance between the cost and the use of demand.
Water Treatment Plants, and Utility Facilities
Pump Stations, Water Treatment Plants, and Utility Facilities, although not a traditional industrial workshop, is also one of the single girder crane application scenarios.
These places mainly use single girder cranes to lift pumps, valves, motors and other equipment, as well as accessories required for daily maintenance, the frequency of operation is not high, mostly intermittent maintenance lifting.
Moreover, the indoor space of these places is usually more compact, single girder cranes are compact and flexible, and can complete the lifting task in limited space without occupying too much space.
Small Precast / Building Material Workshops (Non-heavy-duty zones)
Small Precast and Building Material Workshops (Non-heavy-duty zones) can also use Single Girder Cranes.
For example, the handling of mould fittings for prefabricated components, light building materials, and the transfer of tools and jigs in the workshop, single girder cranes can meet the needs.
Daily production of equipment maintenance, also need single girder crane assistance, lifting maintenance parts, reduce manual labour intensity.
Note here: if the high frequency, heavy load of prefabricated components lifting, the level of operation more than the single girder crane range, it is not suitable for use, otherwise it will lead to early wear and tear of the equipment, a potential safety hazard.
Offset Electric Single-Girder Crane
and Light Industry Plants (Non-hygienic-special versions as applicable)
Food, Packaging, and Light Industry Plants can also use Single Girder Cranes as long as they are not in areas with special hygiene requirements.
For example, equipment parts, packaging materials, production accessories in the workshop need to be transferred between workstations, single girder cranes are easy to operate, will not pollute the production environment, just fit.
Daily equipment maintenance, such as packaging machines, processing equipment dismantling and repair, also need single girder crane lifting parts, enhance the maintenance efficiency.
If the workshop has washing, corrosion or strict hygiene requirements, you need to customise special materials, coatings and electrical protection of the single girder crane, ordinary single girder cranes can not be adapted to such environments.
Industries Where Single Girder Overhead Cranes Are Commonly Used
In addition to the division of the work scene, single girder cranes in different industries also have a clear focus on the application, the following with you, which industries most often use single girder overhead cranes, to facilitate buyers in different industries into the seat.

Warehousing & Distribution Centres (Industrial)
In industrial warehousing and distribution centres, single girder cranes are mainly used for internal cargo transfer and equipment maintenance.
For example, boxes of industrial goods, parts, from one area of the warehouse lifting to another area, or from the warehouse lifting to the transport vehicle, single girder crane operation flexibility, can effectively use the warehouse space.
Maintenance of equipment in the warehouse, such as shelves and conveyors, also requires a single girder crane to lift and transport maintenance parts to ensure that maintenance work is carried out smoothly.
Utilities & Municipal Facilities
Utilities and municipal facilities, such as water plants, pumping stations, municipal maintenance workshops, are also areas of application for single girder cranes.
The main needs of these places are equipment maintenance, lifting pumps, valves, motors and other components, the frequency of operation is not high, single girder crane cost-effective and flexible, just to meet the needs.
Typical Materials and Lifting Tasks
Understanding the application scenarios and industries, and then talk to you, single girder cranes can be lifting what materials, to complete what tasks, to help you further judge whether to adapt to their own needs.
Common Load Types
Single girder cranes have a wide range of lifting, mainly focused on light to medium loads, common materials are these:
Various types of mechanical parts, such as motors, pumps, reducers, machine tool spindles, etc. These are the most common materials lifted in workshop maintenance and production.
Light to medium steel structure parts, such as steel plates, profiles, small prefabricated components, as long as the load is within the rated range, single girder cranes are capable of handling.
Moulds and fixtures, large moulds and fixtures used in workshop production are of moderate weight and need to be lifted accurately, and the fine-tuning function of single girder crane can meet the demand.
There are also palletised goods, maintenance equipment, motors, pumps, etc. As long as the rated load is not exceeded, single girder cranes can easily lift them.
Common Lifting Attachments / Configurations
The lifting method of single girder crane is mainly realised by different lifting attachments, and these are the common configurations:
Hook is the most standard configuration, almost all single girder cranes will be equipped with, suitable for most common materials lifting, simple operation, versatility.
Electric hoists are divided into wire rope hoists and chain hoists, wire rope hoists are suitable for slightly larger load scenarios, while chain hoists are more suitable for scenes where space is tight and precise lifting is required.
For long materials, such as profiles and steel plates, it can be used with a lifting beam, which can make the materials receive even force and avoid tilting and slipping during the lifting process.
There are also some workshop-specific fixtures, such as vacuum suction cups for lifting plates and special fixtures for lifting pipes, which can be matched according to the specific lifting needs to improve lifting efficiency and safety.
