A Concrete Placing Boom is an auxiliary device that connects to a concrete pump via delivery pipes, designed to efficiently distribute concrete over a specific area . Its key features include a multi-section, articulating boom (often with R or Z-shaped folding sections) that provides a 360° rotation for extensive coverage, allowing precise placement for walls, columns, and other structures . Operation is typically hydraulically controlled via a remote or panel, ensuring smooth and safe handling . There are two main types: highly portable mobile (or "spider") booms for varied sites, and self-climbing booms for high-rise buildings, which ascend elevator shafts or floor openings . This equipment significantly enhances pouring efficiency, improves placement accuracy, and reduces labor intensity on construction sites .
