Concrete pumps are now the most popular method of transferring liquid concrete and are a common fixture on building sites now. The birth of the concrete pump has increased the efficiency of building projects, especially when it comes to building high-rises. Whereas previously buckets of concrete had to be lifted up by cranes, it is now possible to pump concrete up to higher floors. This provides a fast and constant supply of concrete exactly to where it is needed.
But how do they work? The answer is actually remarkably simple which probably in part accounts for the popularity and reliability of the humble concrete pump. Two cylinders are placed side-by-side and in each cylinder is a piston. One piston draws the liquid concrete into the cylinder whilst the other simultaneously pushes the concrete out. There is a valve which determines which cylinder is open to the concrete hopper and which is open to the discharge pipes.
As previously mentioned, concrete pumps offer many benefits over the more traditional method of concrete supply, namely using a bucket and crane system. The two main benefits are that concrete pumps can supply a far greater supply of concrete per hour, and the supply is constant. This means that there are fewer wasted man hours as workers will not have to wait around for the next bucket of concrete to arrive by crane.
Using a separate boom means it’s also possible to place the concrete exactly where it is needed, meaning lower labour costs. Also by having a dedicated concrete pump, the crane which would have otherwise been lifting buckets of concrete can now be used for other jobs.
Finally, mobile pumps mean a far quicker setup time. All that needs to happen is the boom must be placed and the outriggers set up and the pump can be delivering concrete within an hour!
