Is it necessary to invest in a double-girder overhead crane? There are several factors to consider when choosing a crane that will meet your needs. You must consider weight capacity, span, hook approach, and other factors while purchasing a double-girder overhead crane. Here are the most important factors to consider when purchasing a crane for your application.

Double girder overhead cranes

What is a double girder overhead crane? A double-girder overhead crane is a bridge crane with two or more overhead runways constructed into the building's support structure and two girders (the bridge) extending between the runways for the crane bay's width.

End trucks are located at the ends of each girder and move the girders and hoist as a single unit along the length of the runways. Typically, the trolley and hoist run along the top of the girder.

• Overhead cranes with double girders have several advantages over single-girder cranes:
• Increasing the hook height (the distance above the floor that the hoist can lift). Hook heights are often up to 36 inches higher than single girder cranes.
• Maximum span has no restrictions.
• There are no restrictions on the maximum lifting capacity.

Select your double girder overhead crane for your application

Weight Capacity

The amount of weight you will be lifting and moving is the first item on your checklist.  overhead cranes with two girders are developed and engineered to lift huge loads frequently. This usually refers to cargo weighing 20 tons or greater.

A double-girder overhead crane is overkill if your application requires you to lift and move loads weighing less than 20 tons. Purchasing a single-girder crane instead will save you time and money.

Span

The span in which your crane will operate is the next thing to check. Cranes with spans more than 60 feet often require double girder cranes or monobox cranes. Remember that rolled section girders for cranes exceeding 60 feet must often be spliced, which adds a significant amount of weight to the crane.

Eot Crane Duty Classification

The loads and cycles of all  overhead cranes are categorized. The categorization determines how heavy the loads are and how many cycles the crane completes in a certain amount of time.Make sure the double-girder overhead crane you buy is classified correctly for your application.

Hook Height

Each runway beam is supported by a top-running, double-girder overhead crane. Each runway beam is supported by an under-running, double-girder overhead crane (also known as an underhung crane).

Top-running cranes can support more weight than under-running cranes. They also have the highest hook height and the most overhead room. Choose a top-running, double-girder crane if you need the most headroom or hook height.

Hook Approach

Keep in mind that, for both trolley and bridge travel, double-girder  overhead cranes have a smaller hook approach than single-girder  overhead cranes, especially on top-running cranes. This has a bearing on how you use the space beneath the crane. If you're replacing a single-girder overhead crane with a double-girder model, don't expect the double-girder crane's hook to reach as far as the single-girder crane's hook did, since it won't.

Installation

The bridge beams and runway systems for double-girder  overhead cranes require extra material. They also put more strain on the structure and foundation of your building. To manage the additional deadweight that comes with two girders instead of one, your crane may require additional tie-backs or support columns. Include these costs in your overall purchase and installation costs. Check more on double girder overhead crane installation.

Double girder overhead crane manufacturer

The company behind the crane is the last factor to consider. Is the company solely focused on crane manufacturing, or does it also provide a wide range of other services? Your best bet is to go with a crane that has been developed, engineered, and built by a company that also provides:

• Engineering help for installations
• Personalized manufacture to your exact specifications
• Double girder overhead crane parts
• Services of maintenance
• Certified experts perform inspections
• Risk evaluations to record the state of your cranes and components
• Operator training
