Single Girder vs. Double Girder Overhead Crane: Key Differences

Single girder overhead crane overview

Henan Mine Crane Factory supply single girder overhead crane is a lifting equipment with a relatively simple structure. The core structure consists of a main beam, an end beam, an electric hoist and an operating track system. The electric hoist moves along the main beam to achieve vertical lifting and horizontal handling of heavy objects. The overall design is lightweight and the layout is compact.Its main components have a clear division of labor, a single main beam bears the main force, the end beam is connected to the main beam and drives the equipment to run along the track, the electric hoist is the core lifting component, and the operating track provides a stable operating path for the equipment.

The application scenarios of this type of crane are very wide. It is mainly suitable for small workshops, warehouses, maintenance workshops and light manufacturing environments. It is suitable for light-load and low-frequency material handling operations, such as hoisting small parts in the workshop and regular handling of warehouse goods.The core advantages of single girder overhead crane are very prominent. Not only is the initial investment cost low and the cost performance is extremely high, but the structure is lightweight. The bearing capacity of the supporting steel structure of the plant is low, and there is no need to strengthen the plant. At the same time, the installation process is simple, the construction cycle is short, and it can be put into use quickly. Transportation costs are also reduced because the lightweight structure is easy to transport and load and unload, and the overall adaptation is limited. Lifting requirements can meet the needs of most light-duty operation scenarios.

Double girder overhead crane overview

Single Girder vs. Double Girder Crane Price Comparison

Average price range comparison

In order to allow enterprises to more intuitively understand the cost differences between the two, we have compiled a comparison table of core indicators. It should be noted that the actual price will fluctuate according to specific technical parameters, customized needs and market conditions. The following is the reference range under conventional working conditions：

Why single girder cranes cost less

The initial cost of single girder overhead crane is lower. The core stems from the multiple cost savings in the structure and manufacturing links. The design of a single main beam significantly reduces the amount of steel used and effectively reduces the cost of raw materials. At the same time, the end beam and other components are smaller in size, simpler in structure, and less difficult to process, which reduces manufacturing costs. The hoist system is also more concise, eliminating the need for complex transmission and control components, further reducing component procurement costs, coupled with simple manufacturing processes, short production cycles, and less labor and equipment investment, and the lightweight structure is easy to transport, the installation process is simple, and there is no need for large hoisting equipment and complex construction teams. Transportation And installation costs have also been effectively controlled, compressing the overall cost of equipment as a whole.

Why double girder cranes have higher prices

The price of double girder overhead crane is higher, mainly because it invests more in the structure, components and manufacturing links. The design of double girder requires more steel to ensure the carrying capacity, which makes the cost of raw materials significantly higher. At the same time, the structural components are larger in size and higher in strength. The processing difficulty and raw material cost of heavy-duty end beams, thickened main beams and other components are higher than that of single girder overhead crane, coupled with the larger capacity of the lifting mechanism, the procurement cost of hoist systems, motors and other components adapted to heavy-duty requirements is higher, and the manufacturing process is more complex, requiring higher machining accuracy and welding technology, labor More investment in equipment, in addition to higher engineering design requirements, special force analysis and structural optimization need to be carried out for heavy-duty and long-span scenarios, which further increases the design cost, and multiple factors together push up the overall quotation of Double girder overhead crane.

Factors That Influence Overhead Crane Prices

Lifting capacity and load requirements

Lifting weight is the core factor affecting the price of cranes. The larger the load, the higher the requirements for the structural strength of the equipment, motor power, and component bearing capacity, and the price will naturally rise.Generally speaking, the mainstream lifting weight of single girder overhead crane is 1-10 tons, which is suitable for light loads.The lifting weight of Double girder overhead crane covers more than 10-100 tons, which can meet the needs of heavy and even super heavy loads.In heavy-duty lifting scenarios, equipment requires stronger main beams, higher-power motors, and more durable transmission components, which will directly drive up equipment costs.Enterprises need to accurately calculate the actual load requirements when selecting models to avoid unnecessary cost waste caused by excessive pursuit of large lifting weights.

Span length and runway design

Span refers to the center distance of the crane's operating track. The longer the span, the higher the strength and stiffness requirements of the main beam. It is necessary to increase the size of the main beam and increase the amount of steel. At the same time, the design and construction costs of the track system will also rise.In addition, the layout of the plant will also affect the track design. If the plant structure is special, customized track transformation is required to further increase the overall cost.When purchasing, enterprises need to choose the appropriate Henan Mine Crane Factory supply crane based on the actual span of the plant to avoid additional cost investment due to mismatched spans.Accurately measure the span of the plant in advance and connect with the manufacturer to optimize the track design, which can effectively control this part of the additional expenses.

Lifting height and hoisting speed

The higher the lifting height, the higher the requirements for the length of the wire rope, the size of the reel, and the power of the lifting mechanism. Longer wire ropes, larger reels, and more powerful lifting systems will increase equipment costs.At the same time, the demand for lifting speed will also affect the selection of motors. If you need to lift quickly and locate accurately, you need to choose a higher-performance motor and transmission system to further improve the equipment quotation.Enterprises need to rationally choose the lifting height and speed according to the actual operating needs to avoid cost waste caused by over-allocation.Reasonable planning of lifting height and speed parameters can not only meet the needs of the operation, but also maximize the control of equipment procurement costs.

Duty class and working frequency

The working level of the crane (such as FEM rating and CMAA classification) directly reflects its working frequency and carrying strength. High-frequency and high-intensity operating scenarios require equipment to have more durable components and more stable performance to reduce wear and failure probability.For example, in the heavy industry scenario of continuous production, high-level cranes need to be selected. The material and processing technology of their components are better than ordinary-level equipment, and the price will be increased accordingly.For light-duty scenarios with low-frequency operations, the use of ordinary work-level single girder overhead crane can meet the needs and the cost is lower.Matching cranes of the corresponding working level according to the operating frequency is the key to balancing cost and equipment service life.

Crane components and customization options

Component selection and customization requirements are important variables that affect prices. The prices of components of different brands and properties vary significantly.For example, well-known brands of gourds, motors, and VFDs have higher prices than ordinary parts, but their performance is more stable and their service life is longer.Customized configurations such as remote control systems and safety protection devices, such as overload protection, limit protection, explosion-proof design, and outdoor protection systems, will also increase equipment costs.Enterprises need to combine the operating environment and safety needs, reasonably choose customized configurations, and balance cost and performance.Priority is given to the selection of core components with a high price ratio, and customized configurations are matched as needed, which can effectively control the overall quotation of the equipment.
