Concrete Pumps | What is a concrete pump?

A concrete pump is a tool for conveying liquid concrete. Over a period of more than half a century, concrete pumps have slowly taken over from other methods of transferring liquid concrete. 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

Concrete Pumping - How to Pump Cement - Concrete Network

Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.

Modelling, simulation and identification of a mobile

Due to the light-weight construction of modern large-scale manipulators used, e.g., in mobile concrete pumps, the elasticity of the construction elements plays a significant role in the dynamic behaviour of the system. Therefore, current research is concerned with control strategies for active damping of elastic vibrations and trajectory planning.

Concrete Pumping| Concrete Construction Magazine

Pumping booms have vertical reaches of 60 feet and up and line diameters of 3, 4 or 5 inches. The reach of boom pumps can be further extended by attaching the boom to a pipeline system set up at the jobsite. PUMP OUTPUT. For any concrete pump, the maximum attainable output in cubic yards per hour will decrease as line resistance increases.

Concrete for Pumping| Concrete Construction Magazine

Concrete for Pumping. Experience has shown that gradation of both fine and coarse aggregate is often the most important factor in determining the pumpability of a concrete mixture, although other mix design characteristics also contribute. If gradation is poor, the excess of some aggregate sizes or efficiency of others will produce voids in the

Estimating Ready Mixed Concrete On-site Dispatch Time - PM

The study revealed that concrete slump and volume have small impact on the dispatch time using concrete pump (R = 0.366; R 2 = 0.134; F-model = 1.676 [with p > 0.05]). It was thus concluded that concrete slump and volume have small effect on the dispatch time on ready mixed concrete.
