A concrete pump truck is usually a boom pump mounted on a mobile truck that is used to move liquid concrete by pumping it using electrical and hydraulic systems integrated in the pump. Concrete moves from the hooper, into the transmission pipes to the discharge hooper from where it is placed on the required area. The pump length usually varies coming with lengths of 35, 50, and 65 or in rare cases 100 meters. The pump is usually folded for ease during transit but usually unfolds and can be controlled and directed to the area where the concrete is to be placed.

The distribution pump is usually mounted on the chassis of a truck to aid in the mobility and to facilitate the movement of the pump to the project site for concrete pumping. The pump can be operated by controls mounted on the truck or remotely using radio control. Distributor boom pumps on concrete pump trucks are usually available in various designs. The most common designs are the multifold, Z fold and roll fold designs.

 

 

The pump works by having a concrete truck empty its concrete in a hooper that is usually on the rear end of the pump truck. To prevent rocks that would clog the pump hoses from getting through the hooper contains a mesh grate. The pump also has an augur that churns the concrete so that it remains in the liquid form so that it can easily flow through the transmission pipes. After being emptied into the hooper, the concrete is subsequently sucked into the valve system through strokes. It is then pushed into the conveyor of hose pipes in liquid form until it reaches the end of the pump pipe. The discharge hooper usually deposits the concrete and it is places it where it is needed.

The operation of the concrete pump truck involves the use of electric and hydraulic systems. There is usually interlinked material and hydraulic cylinders. The material cylinder fetches concrete from the hooper by retracting. Material loaded onto the cylinder is ushered into the S-tube and consequently into the delivery lines by the concrete piston. The material cylinders work interchangeably and simultaneously to ensure continuous concrete movement. Usually the engine provides the operation power of the pump.

To ensure safety and stability the pump usually has front and back outriggers which it can mount on for extra support and balance during concrete pumping. Some outriggers can be extended upto the front of the vehicle. This increases the working range during pumping. The outriggers also minimise the force exerted on the chassis by the distributor boom.

A concrete pump truck is hence is a pumping system mounted onto a truck chassis that employs hydraulic and electrical systems to move concrete deposited into the hooper by a concrete truck to the desired placement position. Precision control and high pump outputs usually ensure the efficient delivery of concrete. Surely a concrete pump truck is the most reliable and efficient means of placing concrete on a construction site.
