1) The placing boom has a R-shaped boom assembly with three foldable sections, wich 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.
3) Featuring compact structure, the placing boom can be 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.
