Determination of Scope of Two-Arm Concrete Placing Booms

The boom, with which the distribution and placing of concrete mix are carried out at the most crucial—the final stage, is an important element of the technology of concrete works. The use of equipment such as a concrete placing boom in contemporary monolithic technologies is steadily expanding. The concrete placing boom allows one to remove from the staff involved in the acceptance and pouring of the concrete part of the load associated with monitoring the correct operation of the concrete feeding equipment, and to focus fully on compliance with the technology of placing concrete. As a matter of fact, the boom is the final element of the pipeline transport of the concrete mixture, guiding it to the right place and at the right time for unloading, therefore, like cranes, it must have at least two mechanisms: one varying the reach and the other varying rotation. In this case, the mechanisms can have either a manual or hydraulic drive, respectively, they distinguish the mechanical booms (with manual control) and the ones with hydraulic control.
