Concrete pump - Wikipedia

A concrete pump is a machine used for transferring liquid concrete by pumping.There are two 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
