A concrete placing boom is a multi-section, remotely controlled arm that mounts on a structure or a mobile base and delivers pumped concrete directly to the discharge point. Instead of manually dragging a flexible delivery hose across rebar and formwork, a single operator uses a wireless remote to position the boom's tip exactly where concrete needs to go - significantly speeding up large-footprint and high-rise pours while reducing the labour and segregation risk of manual hose handling.
