How does a Concrete mixer Pump work?

The operation of the concrete pump encompasses the use of hydraulic and electrical systems. The concrete mixer pump is designed to safely pump wet concrete through a delivery system of pipes and hoses within its published ratings and specifications.
Stability of the concrete mixer pump during operation is provided by the outriggers and front jack. Controls for the outriggers are located on the sides of the concrete mixer pump.
The pumping system employs a special design valve system. This system incorporates material cylinders linked to hydraulic cylinders that cycle alternately. With concrete material in the hopper and the pump operating, a material cylinder retracts, drawing material into the cylinder. At full retraction of the cylinder, a signal is sent to both the swing cylinder and the drive cylinder directional valves causing the pumping system to shift position to the fully loaded material cylinder and the drive cylinders to change direction. The concrete piston of the loaded cylinder then pushes the material through the pumping system and into the delivery lines. The shifting from one cylinder to the other cylinder takes place providing a continuous flow of material through the delivery piping system. The pump can be operated at the control panel or can be operated from the remote control.
