• Stable operation

Robust Design for Reliable Performance,the primary support element of a single girder bridge crane is its main beam, typically constructed from high-grade steel such as I-beams or box beams. These materials offer exceptional strength and stiffness. For instance, the I-beam's cross-section is designed to effectively withstand deformation from vertical loads and the horizontal forces generated by the trolley and hoist movement. In contrast, the box beam features a closed profile that provides outstanding resistance to twisting. Throughout the crane's operation, it can effectively manage various stresses from lifting and operational activities, ensuring that the main beam maintains structural integrity and supports the overall stability of the crane system.

Single-girder bridge cranes are widely used in various industrial applications due to their simple structure, high stability and flexible operation. They are designed to efficiently utilize space and carry lighter loads, making them suitable for operations in small working environments. Operators can flexibly control them through remote control or the cab to ensure safe and efficient operations. Therefore, this type of crane has become an indispensable and important equipment in manufacturing, assembly and warehousing.

 

• Easy to operate

The operation of single-girder overhead cranes is mainly achieved through suspended button stations or wireless remote controls. The button layout on these control devices is simple and clear, and usually each button corresponds to a basic action, such as "up", "down", "truck forward", "truck backward", "trolley left", "trolley right". The operator can control the various actions of the crane through simple key operations, without the need for complex command combinations or operating procedures. This intuitive control method allows even operators without much experience to quickly get started after a short training.

 

 

Mechanical Processing Facility: In environments where heavy machinery components, such as large tool beds and columns, are utilized, single-beam bridge cranes play a crucial role. These cranes efficiently transport hefty parts from processing zones to assembly lines, significantly enhancing overall production effectiveness.

Metal Fabrication Sector: Within the metalworking industry, single-beam bridge cranes facilitate the movement of metal sheets and pipes. They transfer raw materials from storage to various processing machines like cutting, stamping, or bending equipment. Once fabrication is complete, the cranes can easily position the finished goods either in storage or for subsequent operations.

Mold Production Workshop: Molds, often substantial and cumbersome, require careful handling. Single-beam bridge cranes are essential for the loading, unloading, and storage of these tools. In a mold production facility, they assist in transferring completed mold components to assembly stations, as well as transporting damaged molds to maintenance areas for repairs.

Warehousing and logistics industry
General warehouse: used for loading, unloading and stacking of goods. It can easily lift goods in various packaging forms, such as cartons, pallets, etc., and place them in the appropriate position of the warehouse shelves. In large e-commerce warehouses, goods can be quickly lifted from the incoming area to the storage area, or moved from the storage area to the shipping area.
Port terminal warehouse: In addition to handling general goods, it can also handle some large equipment or goods that need to be stored in port warehouses for a short period of time. For example, some large imported mechanical equipment are unloaded from the port transportation vehicle by a single-beam bridge crane and temporarily stored in the terminal warehouse waiting for transshipment.

 

 

The main purpose of using plastic film to wrap single girder eot crane is to prevent dust. During transportation, the crane may pass through some dusty places, such as construction sites, roads near mines, etc. For example, if the crane is used directly for equipment installation in a precision machining workshop after transportation, excessive dust may affect the normal operation of its electrical system and mechanical parts.
At the same time, plastic film can also prevent slight rain erosion to a certain extent.

The main purpose of canvas packaging is to provide better protection, especially for situations where it may be hit or scratched. For example, during transportation, if the crane has a slight collision with the carriage wall or other goods, the canvas can act as a buffer to reduce damage to the crane itself.
Canvas also has a certain degree of air permeability. Compared with completely sealed packaging materials, it can prevent water vapor condensation inside the packaging. This is very important for some crane parts that are more sensitive to humidity, such as electrical control cabinets. If the humidity inside the package is too high, electrical components may be damaged by moisture.

Q: What is single girder overhead crane?

Single girder bridge cranes are lifting machines consisting of a main beam, known for their simple design and high efficiency.

Q: What is the difference between single girder and double girder crane?

A: Single girder crane and double girder crane are two common types of overhead cranes used in various industrial applications. The main difference between these two types of cranes is the number of girders they have.

 

Single girder crane, as the name suggests, has only one main load-bearing girder, which is supported by end trucks on either side. This type of crane is most commonly used for lighter loads and shorter spans, making it more economical than its double girder counterpart. Single girder cranes are also usually lighter in weight and easier to install and maintain.

 

On the other hand, double girder crane has two parallel girders installed on top of the end trucks, making it capable of handling heavier loads and longer spans. This type of crane is more commonly used in heavy-duty industrial applications, such as steel mills, shipyards, and manufacturing plants. Double girder cranes are also more flexible and can be customized to suit specific needs, such as adding hoists, trolleys, and other specialized equipment.

 

Overall, whether you need a single girder or double girder crane depends on your specific lifting requirements. While single girder cranes offer a more economical option for lighter loads and shorter spans, double girder cranes are the better choice for heavier loads and longer spans. Regardless of which type you choose, both single girder and double girder cranes are reliable and efficient equipment that can improve overall productivity and safety in your workplace.

 

Q: What is the highest capacity of single girder crane?
