Types of Double Girder Bridge Cranes
Double girder bridge cranes are categorized based on their design and application. Top-running cranes have the bridge structure running above the crane runway, while under-running cranes have the bridge structure running below. Each type has advantages and disadvantages concerning accessibility, headroom requirements, and overall cost. Dejun Crane (www.dejuncrane.com) offers both top and under-running options.
Comparison Table: Types of Double Girder Bridge Cranes
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Top Running | Bridge structure runs on top of the runway girders. | Easier maintenance access, better protection from environmental factors. | Requires more headroom, potentially higher initial cost. |
| Under Running | Bridge structure runs beneath the runway girders. | Less headroom required, potentially lower initial cost. | More challenging maintenance access, greater exposure to elements. |
