Frequently Asked Questions
What is the maximum under-bridge working depth?
Typically 14-22 meters, depending on configuration.
Does it require full road closure?
In many cases, partial lane control is sufficient due to lateral boom reach.
Can it operate on different bridge types?
Yes, suitable for beam bridges, arch bridges, cable-stayed bridges, and viaducts.
Is customization available?
Yes, working height, platform capacity, and control systems can be tailored.
What makes the folding boom design advantageous?
It allows flexible access to complex bridge structures and improves operational efficiency.
