What it is
A piston pump that drives fresh concrete through rigid and flexible pipe to the point of placing, truck-mounted with an articulated boom. It replaces barrows and crane buckets and allows concreting at great height.
Piston pumps date from 1927-1932 (Fritz Hell in Germany, Kooyman in the Netherlands) and Putzmeister's hydraulic boom pumps from the 1950s-60s; the exact date and author of each step are uncertain.
What it led to
- concreting skyscrapers and tunnels through pipelines
- pumping heights of over 600 m
- higher productivity on concrete sites
