How Does a Concrete Pump Work in construction process

For a more technical answer as to how a Daswell concrete pump works, I'll explain how an S-tube valve system works.
Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:MP1500 Planetary Concrete Mixers,cement mixing plant,cement mixers,etc. We will provide you with the best product and service.

The operation of the concrete pump involves the use of hydraulic and electrical systems. This system incorporates material cylinders linked to hydraulic cylinders that cycle alternately. With concrete mix in the hopper and the pump operating, a material cylinder retracts hollow block machine, drawing material into the cylinder.

At full retraction of the cylinder planetary mixer, a signal is sent to both the S-tube swing cylinder and the drive cylinder directional valves causing the S-tube 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 S-tube and into the delivery lines.
