A concrete pump is a machine used for transferring liquid concrete by pumping, is consist of the pump and delivery tube. According to the structural form it can be divided into piston-type, extrusion type and hydraulic diaphragm type. It uses the pressure to make the concrete through the pipeline continuous conveyor to the machinery. It is mainly used in housing construction, bridge and tunnel construction. Currently divided into gate valve concrete pump and concrete pump S valves. Another one is to pump mounted on the vehicle chassis, then equip the retractable and inflectional placing boom to consist the pump truck.
According to the construction and purpose it can be divided into trailer concrete pump, truck-mounted concrete pumps and concrete pump truck. On the basis of the power type it can be divided into electric concrete pump and diesel concrete pump. There are two most common used types of concrete pumps.
The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes. They are a revolutionary reform, instead of the truck-mounted concrete pumps.
The second main type of concrete pump is either mounted on a truck or placed on a trailer, and it is commonly referred to as a line pump or trailer-mounted concrete pump. This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed. Line pumps normally pump concrete at lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single family home concrete slabs and most ground slabs.
