Frequently Asked Questions About Double Girder Overhead Crane

1. What is a double girder overhead crane?

A double girder overhead crane is a type of bridge crane with two main bridge girders. The hoisting trolley runs on top of the two girders, while the whole crane travels along runway beams installed on both sides of the workshop.

It is commonly used for medium-duty and heavy-duty lifting operations requiring higher capacity, larger span, and higher lifting height.

2. What is the difference between a single girder overhead crane and a double girder overhead crane?

A single girder overhead crane has one main bridge girder, while a double girder overhead crane has two main bridge girders.

Single girder cranes are usually used for light to medium-duty lifting operations and are more economical. Double girder cranes are suitable for heavier loads, larger spans, higher lifting heights, and more frequent working conditions.

3. What lifting capacity can a double girder overhead crane handle?

Double girder overhead cranes are commonly used for capacities from 5 tons to 500 tons or more, depending on the crane design and project requirements. ZOKECRANE can customize the lifting capacity according to customer needs.

4. What industries use double girder overhead cranes?

Double girder overhead cranes are widely used in:

• Steel plants
• Machinery manufacturing
• Warehouses
• Power plants
• Construction material plants
• Foundries
• Mining equipment maintenance
• Logistics centers
• Heavy equipment assembly workshops

5. What information should I provide to get a quotation?

To provide an accurate quotation, please share the following information:

1. Lifting capacity
2. Crane span
3. Lifting height
4. Traveling length
5. Working duty or daily working hours
