Abstract Tuogua concrete pump is widely used in the construction of one of the main concrete machinery. General concrete pump from the work of agencies is pushing institutions, distribution of the mixing valve and the hopper device components, thus hydraulic concrete pump the hydraulic system also includes the work of these three institutions: Push agencies loop system that is the main Circuit, Distribution systems and mixing valve Circuit system. All the main use of hydraulic transmission mode. It can be better used in construction, the scope of work. Normal working hours, do not need other ancillary equipment, the use of mobile and flexible. In recent years, popularization and application of the construction of pumping concrete technology, with its high efficiency, low-cost, labour-saving, horizontal and vertical transportation to complete the first row, the use of the advantages of a narrow construction site, people are more and more attention.
