INTRODUCTION
What is this?
The double-girder bridge casting crane is a specialized lifting device designed for high-temperature molten metal handling in steelmaking and foundry workshops. It features a double main beam structure with main and auxiliary hooks, combined with trolley and crane traveling, to achieve safe, stable, and precise lifting and pouring of molten steel ladles and iron ladles. If you are managing a steel plant, foundry, or metallurgical workshop and need a crane that can withstand high-temperature radiation, frequent full-load operation, and provide maximum safety, this product is designed for you.
Why choose a casting crane over a standard overhead crane?
Compared to standard overhead cranes, the casting crane offers five core advantages:
First, safety redundancy design – dual brakes and an overspeed switch on the hoisting mechanism ensure the ladle will not fall even if one brake fails.
Second, high-temperature protection – heat insulation layer on the bottom of the main beam, H-class motor insulation, suitable for 60°C high-temperature environments.
Third, dual hook configuration – main hook for ladle lifting, auxiliary hook for tilting and slag handling, higher operational efficiency.
Fourth, higher working class – A7/A8 very heavy-duty design for continuous full-load operation around the clock.
Fifth, standard load cell – real-time molten steel weighing, dual display in cabin and on bridge for precise pouring control.
Protect the safety and efficiency of high-temperature molten metal handling with professional design.
What can we do for you?
We understand that every customer has different ladle capacities, different workshop spans, and different process layouts. Therefore, we offer flexible customization options: lifting capacity from 5 tons to 550 tons; span from 10.5 meters to 31.5 meters; main/auxiliary hook ratios such as 75/20t, 180/50t, etc.; control options of cabin or remote radio; VVVF speed control for smooth start/stop. Whether your workshop is narrow and compact or wide and spacious, we can match the most suitable span and lifting height.
Unsure? Don't know?
Not sure what main/auxiliary hook capacity ratio to choose? Don't know what lifting speed is needed for ladle handling? No problem. Just tell us: your ladle capacity or molten steel weight, your workshop span, and your handling frequency (how many heats per day). Our engineers will provide you with an accurate quote and CAD drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.
Tip: We offer free selection consulting. Even if you are unsure about specific parameters, feel free to describe your melting process and workshop dimensions, and we will calculate for you.
