Under this circumstances, people invented the concrete pump. With the help of a concrete pump, people can easily convey the mixed concrete to the needed areas. Later, even more convenient concrete mixer pumps are invented to fulfill the task of on site concrete mixing and pouring.
In geotechnical engineering, a caisson (/ˈkeɪsən/ or /ˈkeɪsɒn/; borrowed from French caisson, from Italian cassone, meaning large box, an augmentative of cassa) is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships.[3
Although no definitive record exists documenting the first use of a concrete pump, the first patent for a concrete pump was established in 1913 in the U.S. Germany became the leading technology innovators in concrete pump development, and used the method extensively …
A number of different designs of concrete pump were developed in the first half of the 20th century but it was Friedrich Wilhelm Schwing's company Schwing GmbH which invented the twin cylinder hydraulic concrete pump in 1957. The principle of this design was adopted by almost all other manufacturers and is still the worldwide standard design.
30/1/2021 · A cement pump is a mechanical device used to move quantities of liquid concrete to different locations. Most often, cement pumps are referred to as "concrete pumps" because they actually pump concrete, which is made up of cement, and other materials such as water, sand, and gravel. There are three basic types of cement pumps, the boom pump, the

21/4/2009 · Monolithic's 2000 pumps will spray about 6 yards of concrete an hour. This is the pump for the builder working on a large project or a number of various projects. Each of Monolithic's pumps is designed on skids, rather than trailers, but they can be put on trailers.
Joseph Monier ( French: [mɔnje]; 8 November 1823, Saint-Quentin-la-Poterie, France – 13 March 1906, Paris) was a French gardener and one of the principal inventors of reinforced concrete .
22/12/2011 · 1929 Stork Pompen produces the first concrete volute pump for drainage, integrating the pump housing in the civil construction of the pumping station. 1930 While inventing a compressor for jet engines, aviation pioneer René Moineau discovers that this principle could also work as a pumping system.The University of Paris awarded Moineau a doctorate of science for his thesis on "the new …
In 1974 CIFA invented the truck mixer pump, in 2010 the company proudly patented the first carbon-fiber-made boom, and in 2013 the first hybrid mixer truck laying the foundations for what in the following years would become a real hybrid range: Energya.
8/10/2009 · Invented by : Otto Von Guericke Invented in year : 1650 Air Pump is a device that removes gas molecules from a sealed volume or a chamber in order to leave behind a partial vacuum. By removing gas from a chamber, a vacuum pump reduces the pressure inside
piston pump powered the mixer, which had a gear-train to drive the chain drive. The addition of a power unit was concrete truck patent, invented by Ackert Bickel of Kansas City, Mo., in 1920. Figure 3. Milwaukeean Charles Ball's "Mixing and was patented in
In 1927 German Engineer named Max Giese and Fritz Hull came with idea of pumping semi liquid concrete at high surface with the help of pressure. In 1932 (Holland), Jacob Cornelius Kweimn gets patent for concrete pump. Concrete pumps can produce upto 1000 atmospheric pressure to pump concrete. Mainly two types of concrete pumps are available- 1.
Concrete Pumps can be categorised into boom pumps, concrete pumps trucks, stationary pumps and concrete line pumps. A Boom Pump A boom pump is a type of concrete pump which is characterised by a controlled hydraulic arm where concrete is placed and …
A concrete vibrator uses an off-centered weight, which is spun as much as 10,000 times a minute, causing large air pockets in the concrete to disperse as the concrete is shaken. Especially in pours of low slump concrete, which uses minimal water, the use of a vibrator is essential to ensure that the concrete does not bubble or form holes.
23/3/2009 · Worthington Pump & Machinery Corporation acquires Worthington Simpson Ltd 1917 John Crane founded; Hydraulic Institute established Louis Bergeron invented the concrete volute pump and founded Bergeron S.A. 1918 Scanpump and CCM Sulzer founded
1/3/2000 · A portable mixer, invented by Alvah Handsel of Wilkes-Barre, Pa., patented on January 12, 1909, employed a hexagonal drum, but not one that rolled along the ground. A coal-fired steam boiler attached to a piston pump powered the mixer, which had a gear-train to drive the chain drive. The addition of a power unit was such a quantum leap over
The Concrete Pump was particularly important in revolutionising the construction of large high rise buildings. Previously cranes had been employed to lift large buckets (or skips) full of concrete up to where it was needed. A crane could lift one bucket at a time, normally holding around 2 cubic yards of concrete.
11/6/2015 · Built in the year 1891, the material was poured by George Bartholomew. The road is incredibly strong, about twice as strong as the concrete we trust and use for today's industrial needs. Thomas Edison designed concrete homes in New Jersey in 1908. The houses were cheap to make, yet durable and resistant to the risk of fire.
