The single girder overhead crane is a lightweight and versatile bridge crane, widely used for light to medium load handling across various industries. As its name suggests, this crane features a single girder design, making it more economical and efficient for lighter lifting tasks compared to double girder models. Depending on operational needs, the lifting mechanism can be equipped with either a wire rope electric hoist or a chain hoist. For safety, the system integrates lifting overload protection and limit protection. Once the hoist reaches its upper or lower limit position, the protection system automatically cuts off the power supply to prevent accidents and ensure safe operation.
The most common configuration of a single girder overhead crane is the top-running type, where the end trucks move along the top of the runway system. However, alternative designs such as under-running cranes or even double girder configurations are also available, offering flexibility to suit different facilities and applications.
One of the primary advantages of the single girder overhead crane is its cost-effectiveness. Since it requires less material and shorter fabrication time compared to double girder cranes, the initial investment is significantly lower while still providing reliable lifting performance.
How to choose the right overhead crane for your business?
In modern manufacturing, warehousing and logistics, and heavy industry, overhead cranes have become essential equipment for improving productivity and ensuring safe operations. However, faced with the vast array of cranes on the market, many business owners are confused about how to choose the most suitable bridge crane for their business.
♦Clearing the Application Scenario and Requirements
First, you must understand your business’s industry and application scenarios. For example, manufacturing, steel processing plants, machine shops, or logistics and warehousing centers all have very different requirements for crane load capacity and operating frequency. Clarifying your needs will lay the foundation for subsequent model selection.
♦Determining the Lifting Capacity and Work Class
When selecting a bridge crane, the maximum lifting capacity is a top priority. For light-duty operations, a single girder bridge crane is a good choice. For large-tonnage or high-frequency lifts, a double girder bridge crane should be selected for its stable structure and longer lifespan.
♦Combining Factory Building Conditions
The height, span, and existing track infrastructure of the factory building directly determine the type of bridge crane to choose. For example, workshops with limited space are suitable for suspended overhead cranes, while larger workshops are more suited to double-girder structures. Properly considering plant conditions can avoid unnecessary installation and maintenance hassles.
♦Focus on safety and operation methods
Modern single girder overhead cranes should be equipped with safety systems such as limit switches, overload protection, and emergency power-off devices. Furthermore, depending on the operating environment, joystick control, wireless remote control, or cab operation can be selected to ensure both efficiency and safety.
♦Choosing a reliable supplier
Finally, finding a qualified and experienced overhead crane supplier is crucial. High-quality products coupled with comprehensive after-sales service ensure long-term, stable operation of the equipment and reduce operational risks for your business.
Choosing the right overhead crane for your business requires comprehensive consideration of industry requirements, lifting capacity, plant conditions, safety features, and supplier strength.
