The system has a power limit valve; when engine overload occurs, pump can automatically reduce delivery so as to avoid engine power loss. 2. Engine low speed protection The system has no pumping function when engine speed is lower than 800rpm, so as to avoid engine running with load at low speed, and prolong engine service life. 3.

The EOC module helps the concrete pump save fuel during operation by automatically adjusting the engine to the maximum speed required for the current pumping output. If required, this speed can be increased or decreased at any time via the radio remote control, resulting in lower fuel consumption, less wear and reduced noise levels during pump

Oct 02, 2020 · On average, the concrete pump operator annual salary is $43,086 per year, which translates to $20.71 an hour. Generally speaking, concrete pump operators earn anywhere from $26,000 to $70,000 a year, which means that the top-earning concrete pump operators make $44,000 more than the ones at the lower end of the spectrum.

Jun 01, 2016 · As we know, the power of a truck-mounted concrete pump is at least twice more than that an automobile, for instance the engine power of a truck-mounted concrete pump is 214kW and that the power of a Toyota Prius is only 73kW[2]. So the energy conservation technology is much more important than an automobile.

Jun 08, 2018 · The load on the system results from the delivery of fresh concrete. To model the fresh concrete, a simplified model of the material is created, which shows the properties that are the most important for the load of the pump. These relevant fresh-concrete properties represent the behavior of the concrete in the delivery cylinder and in the pipeline.
