Concrete pumps have become indispensable within the construction industry due to the advancement in the industry and the type of buildings and projects that can be carried out at this time, greatly helped by these aforementioned teams.
The reliability of concrete pumps during operation is provided by stabilizers and by their front controls, which are located on the sides of the pump.
The pumping system uses an “S” valve design, which is named for its shape. This system incorporates cylinders linked to hydraulic cylinders that rotate alternately. With concrete in the hopper, and the pump running, the concrete in the cylinder retracts, molding within the cylinder. With the full retraction of the cylinder, a signal is sent to the valve cylinder "S" and the directional cylinder causing the valve "S" to advance its position and change the direction material. The concrete piston of the loaded cylinder then pushes through the “S” tube and into the delivery lines. Advancing from one cylinder to another takes place by delivering a continuous flow of material through the piping system. The pump can be operated from the control panel or also by remote control.
The flow of hydraulic oil created by the hydraulic pump pushes in the direction of the cylinders alternately forwards and backward. Because the concrete cylinders and pistons are linked with the concrete cylinders, the pistons move synchronously. When a cylinder is retracted with the concrete piston it is sucked from the hopper into the concrete cylinder. Simultaneously, the other cylinder and the piston are extended towards the hopper. The concrete piston will push the concrete from the concrete cylinders through the “S” valve and out into the delivery system. Then the pump switches at the end of the cycle, causing the "S" valve to go ahead of the concrete cylinder which has sucked and filled the cylinder with a concrete starting the next cycle.
Reverse pumping joins the piston in a suction flow and causes the “S” valve to suck from the “S” tube instead of the hopper. As a result, the concrete piston pumps concrete into the hopper. The power to operate the concrete pump is provided by the motor, which drives the hydraulic pump.
All functions for concrete pump operation can be accessed from local controls mounted on the side of the unit, however, there are optional portable cables or remote controls to operate the pump remotely.
