Concrete placing boom

Concrete placing boom One cannot imagine modern construction site without concrete pumping machinery. Transferring of liquid concrete by piping is realized by three types of concrete pump units: boom pump (or truck mounted), line pump (stationary pump) and separate concrete placing boom. Boom pumps are generally used in large jobsites due to combination of high pumping capability, possibility of saving time and manual labor. Line pumps transfer concrete a little bit slower and demand additional manpower, they are applied in smaller construction sites. Separate concrete placing boom can be used in locations where it is not convenient to use the boom truck. The weighty arguments to use concrete placing booms are:

  • Concrete pumping is necessary to be done on the height where the boom pump fails to achieve or the jobsite area is too large to be covered by line pumps or boom pumps opportunities.
  • Some structures such as columns, internal bridges or coverings do not allow using stationary pumps at all or make the application of such machinery very complicated.

Concrete placing booms are ideal variant to choose if you are working on the large area (up to 450 square meters). By means of a crane tower they are easily transported to the necessary location and provide good concrete pumping just where you need it!

The self-climbing models allow the boom climbing by itself. The rail-mounted are featuring the ability to meet the demands for concrete placement of long span or high-rise structures and large surfaces. With the ship-mounted model it is easy to work in water, with vertical reach related to tower-body height. Mobile models combine excellent mobility, wide application, high utilization, high safety and reliability, easy transportation by means of a crane.

Normally, the boom is set on a pedestal or a rotating platform, which can be located hundreds of feet from the pump and connected with a pipeline. The standard elements of the separate concrete placing boom can be the following: the boom itself for concrete distribution, a kind of mast, rotating platform, an adaptor connecting the mast and rotating platform (it provides quick assembling and dissembling of the unit) and concrete supply piping from the pump itself to the place of location of separate concrete placing boom.

There are various mounting options for placing booms: foundation is mounted with bolted cross frame, boom and mast are fixed on crane tower, the mast itself can be fixed to the side of structure by means of brackets, it is possible also to insert the boom and mast in the floor slab by wedges, sometimes the boom with the mast are anchored to a supporting surface.

So, application of separate concrete placing boom can be really of great help in specific situations on the jobsite. Combined with the right concrete pump, separate placing booms provide high-quality concrete distribution and improve the working efficiency.
