Concrete is a mixture that is made by combining sand, gravel, cement and water and one that is fluid in it is initial state, but then sets after the cement gains its initial set state. The fact that it is fluid has led to the development of mechanisms that can pump concrete to enable its placing at the exact points where it is required. These concrete boom pump truck for sale which function in the same way that any other fluid pump works can be stationary and have hoses attached to the discharge end of the pump, so that they lead to the point of discharge. The hoses are made of small lengths that can be linked to each other and easily coupled to form larger lengths or smaller lengths, so that the placement of the concrete is precise. These pumps receive mixed concrete from other mixers and then pump the fluid concrete as required. The capacity of this system is limited by the hoses and their diameters and is a system used for smaller quantities.
For larger quantities use is made of a boom pump truck, which have an arm or boom that is articulated and controlled allowing concrete to be placed accurately at any desired location. Most large construction projects use this method to discharge concrete as very high volumes are enabled by this system, and the boom itself leads to a large saving in any labor required for placing the concrete. It is quite common to have a single skilled worker manipulating the boom for even large amounts of concrete placing. These pumps are attached to trucks and this mobility gives any construction site a lot of flexibility in its ability to achieve set concreting targets, which form the basis for the completion of many construction projects.
The use of these pumps has largely been responsible for the ease of construction of high rise buildings. Some of these pumps can reach heights and distances of 175 feet making them the first choice for engineers entrusted with completing skyscrapers. Concrete boom pumps for sale need a substantial investment and can also be available as a used pump from projects that have concluded their use. It is important that concrete mixes have the right fluidity that enables the concrete to move easily to the pump and in time before any initial set takes place.
Additives can do this work, but it is more important to see that the concrete itself is of the right pump able quality, and which yet gives the required strength. The strength of concrete depends on the water cement ratio and a proper judgment needs to be made to ensure that this in no way reduces strength while maintaining the required fluidity which will enable it to move through the pump and its boom without any problems.
Correct positioning of the pump can also affect efficiencies and this is a judgment call that quite often affects production. A lot of care is also necessary to ensure that the movement of the boom is not hampered by power lines or other structures. Booms are made of definite lengths that will be folded over when not in use and then extended when they are to be put into use. This operation has to be done very carefully and must always be properly supervised. Pumps and their booms must also be carefully maintained and cleaned after each concreting operation is concluded.
