Concrete is a mixture of cement, aggregates, and water that when it is first mixed is in liquid form and thus can be pumped, like water or any other liquid. This pumping has to be carried out before the concrete gains its initial set, and this does impose certain restrictions on this method of placing concrete.
Traditionally, concrete is mixed in concrete mixers and brought to the location where the concrete is needed, and then placed there by unloading into skips or buckets that are then lifted by cranes or other equipment to enable the concrete-filled container to be positioned at the location where it is required. The skip or bucket is unloaded at one spot, and then manually or with other equipment spread to the thickness at the location where it is required. If a pompa beton is used, the concrete can be placed at the exact point where is required, and with the thickness required, so that no other effort is required.
Concrete pumps deliver the concrete through pipes that have to bridge the distance between the pump and the location where the concrete is required. Boom concrete pumps will have a number of booms or lengths that are hinged to each other, and carry the pipes through which the concrete is pumped. The hinges allow the various sections of the booms
to be manipulated in any direction so that it can telescope or extend to reach all the locations where the concrete requires to be delivered. The boom is an articulating robot arm that is remote controlled and this allows concrete to be placed accurately and exactly where it is required.
Boom pumps for sale can be stationary or mounted on trucks or trailers that further increase the flexibility of use. Booms can be both extended and rotated. Most of these mechanisms can be controlled mechanically or hydraulically. The booms supplying the concrete through pipes that are attached to these booms can be folded to become compact, when not in use, or when the pump location itself is being changed. During concreting operations, the booms that are hinged on each other can be manipulated and rotated, so that the last section of the pipe carrying concrete can be at the exact point where the concrete is required.
Concrete -placing booms attached to the pump can also be attached to columns or masts of cranes, an arrangement that is frequently seen in high rise buildings and can deliver the concrete through the pump at great heights. Most concrete boom truck also require the use of air compressors or water pumps that are used to purge the concrete carrying pipes of concrete at the end of a day’s work.
Boom concrete pumps are used in most large construction projects as it is possible to place large volumes of concrete accurately, leading to large savings in labor costs, while greatly speeding up the work. The model used on a project, truck-mounted or stationary, will depend on the frequency of the requirement of concrete on a particular project.
