Benefis of Using Double Girder Overhead Cranes

Using double girder overhead cranes provides several benefits for businesses and industries. Here are some key advantages of using double girder cranes:

High Lifting Capacity:
Double girder overhead cranes are designed to handle heavy loads with ease. The presence of two girders increases the overall structural strength, allowing the overhead crane to lift and transfer heavier loads compared to single girder overhead cranes. The high lifting capacity is beneficial for industries dealing with large and heavy materials.

Enhanced Stability
The double girder configuration offers improved stability and rigidity compared to single girder cranes. This stability ensures smoother and more precise movements during lifting and transferring operations. It reduces the risk of load swinging or swaying, improving safety and minimizing the potential for accidents or damage.

Versatility and Adaptability:
Double girder bridge cranes are versatile and can be customized to suit specific work requirements. They can be equipped with various lifting attachments, such as hooks, grabs, magnets, or specialized fixtures, to handle different types of heavy materials. Additionally, the cranes can be integrated with automation systems or remote control for improved efficiency and convenience.

Durability and Longevity:
Double girder bridge cranes are built to withstand demanding industrial environments. They are constructed using robust materials and undergo stringent quality testing to ensure durability and longevity. Investing in a double girder crane means you can rely on its performance for many years, reducing the need for frequent maintenance or replacements.

Improved Safety:
Double girder overhead cranes often come with reliable safety features to protect both the operator and the load. The safety devices include overload protection systems, emergency stop buttons, limit switches, anti-collision systems, and more. These safety features help prevent accidents, enhance operator confidence, and minimize potential damage to the crane and surrounding infrastructure.

Cost-effective Solution:
While double girder overhead cranes may have a higher initial cost compared to some other lifting options, they offer long-term cost benefits. Their high lifting capacity, durability, and versatility result in improved productivity, reduced manual labor, minimized material damage, and fewer maintenance requirements. This leads to overall cost savings in the long run.

How Much Does a Double Girder Overhead Crane Cost?

  • The cost of a double girder overhead crane can vary significantly depending on several factors, including specifications, capacity, span, features, manufacturer and more.
  • Generally, higher-quality cranes tend to have a higher price due to better materials, construction, and additional features. Striking a balance between price and quality is crucial to ensure the crane meets your lifting needs and offers reliability.
  • Check the following Aicrane overhead crane prices for your reference while you are selecting a double girder overhead crane solution for your business.

What Are the Main Components of Overhead Crane?

Overhead crane is generally composed of main beam, end beam, hoisting mechanism, crane moving mechanism, control room, trolley conductive device (auxiliary slide line), crane main power conductive device (main slide line), etc.

main beam

The lifting mechanism is composed of hoisting motor, reducer, drum, brake, etc. The lifting motor is connected with the reducer through the coupling, brake wheel, and the output shaft of the reducer is connected with the winding drum of the steel wire rope. The other end of the steel wire rope is equipped with a hook. When the drum rotates, the hook rises or falls with the winding or releasing of the steel wire rope on the drum.

The heavy objects on the hook moves up and down with the rotation of the drum; the trolley moves left and right in the width direction of the workshop, and moves forward and backward with the cart in the length direction of the workshop.

In this way, it can realize the movement of heavy objects in the perpendicular, horizontal and vertical directions, move the heavy objects to any position in the workshop, and complete the lifting and transportation task.
