1）The placing boom has a Z-shaped or R- shaped boom assembly with three foldable sections, which can swing through 360 degrees while luffing, folding/unfolding, thus allowing it to place concrete to form walls, pipes, columns, piles and other vertical structures without confined placement areas.

2）The boom assembly’s luffing, folding/unfolding and swinging are carried out hydraulically with buttons. The hydraulic and electrical system feature overload protectors, flow controls, alarms, phase sequence protectors and so on, which ensures the placing boom to have reliable performance, easy and smooth operation, and high safety.

3）Featuring compact structure and lightweight, the placing boom can be completely lifted and transferred to any suitable places for concrete placement, such as floors, platforms, simply-structured racks or even trailers. It does not need to be fixed while working. In addition, it can be lifted off the placement sites when it is not needed, which leads to no disturbance to other jobs and easy maintenance.

4）The Spider Concrete Placing boom is well fit for the construction of different floors and for complicated jobsites without being influenced by the size and shape of floors.
