It is a specialised machine used to pump liquid concrete at high volumes. It consists of a truck-mounted pump that is equipped with a long and extendable arm (boom). It can reach high or far distances to pour concrete exactly where needed. In many large-scale construction projects, it can also function similarly to a deep foundation concrete pump, efficiently delivering concrete to lower or structurally critical sections of a build. It can pour concrete in hard-to-reach places like multi-story buildings or sites with limited space.
