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 ...
Putzmeister was founded by Karl Schlecht in 1958. [3] Schlecht designed a mortar machine based on his diploma thesis at the University of Stuttgart. [4]In 1986, Putzmeister 52Z's were used in the Chernobyl nuclear accident, pumping over 300,000 m 3 (390,000 cu yd) of concrete to entomb reactor number 4, setting a world record at the time for volume pumping.
Schwing Concrete pump. The Schwing Group was founded as a medium-sized enterprise on 17 March 1934, by Friedrich Wilhelm Schwing (* 1909; † 1992), a locksmith from Wanne-Eickel. In 1957, Schwing built the world's first oil-hydraulic two-cylinder concrete pump. Starting in 1964, the company also built the first large concrete mixers.
Concrete Pumping earned $0.05 per share in its fiscal second quarter, ending April 30, on revenue of $107.1 million, falling short of Wall Street's estimates of $0.10 per share on $112 million in ...
The scope of the project called for extensive concrete work that consisted of slabs in excess of 2,000,000 square feet and used more than 65,000 cubic yards of concrete to complete. In order to meet the demands of the ambitious timeline for completion of the foundation, Conco worked in four separate areas simultaneously.
The pumping of solids with high solids contents offers a range of possibilities in process engineering. Oil-hydraulically powered two-cylinder piston pumps with S-transfer tube have already been used for many years in civil engineering for transporting concrete.
Peristaltic tube pump with two sprung rollers Peristaltic pump in motion. A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing.
In 1927, the disadvantages of using a conventional pouring tower led engineers Max Giese and Fritz Hell to the idea of pumping concrete from a concrete mixer directly to the point of use. [1] In 1928, Giese invented the concrete pump. The reduced water content in the concrete during the pumping process not only saves energy but also allows the ...
