The application of concrete placing boom in concrete construction is very extensive, mainly used for conveying, distributing, paving, and pouring concrete into molds, including:
Construction site: On construction sites, concrete placing boom are used to evenly spread concrete into designated construction areas, ensuring the thickness and flatness of the concrete.
Bridge construction: In bridge construction, concrete placing boom can quickly and efficiently transport concrete to various parts of the bridge, ensuring the structural stability of the bridge.
Road construction: In road construction, concrete placing boom can quickly lay concrete on the road surface, improving construction efficiency and quality.
