A Double Beam Bridge Crane, also known as a double girder overhead crane or dual beam bridge crane, is a heavy-duty material handling equipment widely used in industrial environments. This sophisticated lifting system consists of two parallel main beams that run on overhead runways, providing superior load capacity, stability, and operational efficiency compared to single beam alternatives.
The double beam configuration features two main structural girders that work in tandem to support and distribute loads evenly. Key structural elements include:
Two parallel main beams running the length of the span
End trucks mounted on each beam end
Hoist mechanism suspended between the beams
Trolley system for lateral movement
Bridge runway system for longitudinal travel
One of the primary advantages of double beam bridge cranes is their exceptional load capacity. These systems typically handle loads ranging from 5 tons to 500+ tons, making them ideal for heavy industrial applications.
Steel mills and metalworking facilities
Automotive production lines
Heavy machinery assembly plants
Fabrication shops and foundries
Large-scale warehousing operations
Port and shipping facilities
Distribution centers
Container handling yards
Paper mills
Chemical plants
Nuclear facilities
Aerospace manufacturing
Double beam cranes can handle significantly heavier loads than single beam alternatives, with better weight distribution across two structural members.
The dual beam configuration provides enhanced stability and reduced deflection, even under off-center loading conditions.
These cranes can achieve longer spans without excessive deflection, providing greater operational flexibility.
The dual beam system allows for more precise load positioning and control during lifting operations.
Robust construction ensures extended service life and lower maintenance costs over time.
Multiple structural redundancies and advanced control systems enhance workplace safety.
