A concrete pump is a machine used for transferring liquid concrete by pumping. There are different types of concrete pumps.
A common type of concrete pump for large scale construction projects is known as a boom concrete pump, because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. It is attached to a truck or a semi-trailer. Boom pumps are capable of pumping at very high volumes and are less labor intensive to operate when compared to line or other types of concrete pumps.
The second main type of concrete pump, commonly referred to as a “line pump” or trailer-mounted concrete pump, is either mounted on a truck or placed on a trailer. This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine and feed the concrete to the place of application. The length of the hoses varies, depending on the diameter. Due to their lower pump volume, line pumps are used for smaller volume concrete placing applications such as swimming pools, sidewalks, single family home concrete slabs and most ground slabs.
There are also skid mounted and rail mounted concrete pumps, but these are uncommon and only used on specialized jobsites such as mines and tunnels.
