The use of concrete placing booms has been wisely adopted in the UK, especially for building reinforced concrete frames on inner city sites where space is at a premium. Previously Camfaud would carry out these contracts using boom pumps with additional pipeline and labour where necessary. Now, however, as a result of demand from customers, we offer a range ofstatic concrete pumps and stationary placing booms complete with a full installation and maintenance service. RC frame, cores, slips and high rise are the type of projects that would benefit from this concrete placement solution.

With this system, the concrete is normally pumped by a diesel or electrically powered static concrete pump, through a fixed 125 mm pipeline, to the stationary placing boom. The Schwing SPB 30 boom can be mounted on a steel column of up to 20 metres. The column can be supported on a free standing cross base (Concrete or steel ballast weights required) or have bolts cast into the base slab. Once the structure starts to rise the column is captured by floor frames and rises with the building. This system will help place concrete safely and efficiently and has the added benefit or releasing hook time to help drive productivity. On larger sites, one boom can be used in conjunction with two or more columns allowing effective coverage of larger areas. The boom can be moved from one column to another and can be split into two sections, where required, to fall within the max lifting weight of the crane.
We also have a growing number of smaller booms which can be free standing, mounted on columns or designed to sit on slip shutters or cores. These can be connected to statics or mobile boom pumps to help reduce or replace static pipeline across the site. This will help increase the speed of each pour, reduce labour requirement, and improve the safe placement of the concrete.
Some of my construction industry friends ask me why they should use a concrete placing boom, they already have a concrete pump and stationary pump, it can do most of the job. Now I give a brief introduction of placing boom and tell you what a placing boom can do and a concrete pump can't.
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 job sites 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. According to our experience, the weighty arguments to use concrete placing booms are:
1. Concrete pumping is necessary to be done on the height where the boom pump fails to achieve or the job site area is too large to be covered by line pumps or boom pumps opportunities.
JIDA are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
2. 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 tower crane they are easily transported to the necessary location and provide good concrete pumping just where you need it!
Various types of concrete placing booms are available in order to meet your specific requirements: stationary, self-climbing, rail-mounted, floor-mounted and even ship-mounted concrete placing booms. 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 adapter 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 job site. Combined with the right concrete pump, separate placing booms provide high-quality concrete distribution and improve the working efficiency.
