Concrete pump car refers to a kind of building construction equipment as a bestselling item in the market. Also known as truck mounted concrete pump or placing pump or concrete boom pump, its whole frame is mounted on one mortar-vehicle chassis.

Aimix Group produces all kinds of concrete pump machines, such as concrete mixer pump, trailer pump, diesel concrete pumps and electric cement pumps in Sri Lanka markets.
Main Frame:
- Boom System: Boom, oil cylinder, connection parts.
- Chassis: Automotive chassis, PTO, auxiliary girder.
- Pumping System
How Does the Concrete Pump Boom Car Work?
Power and motion transmission gear, concrete mixing and pumping gear, placing boom and other auxiliary devices are mainly mounted upon the chassis. The placing boom can stretch over an area or distance covers for tens of meters and return to its original size.
It is an integrated construction machine with the ability to mix the cement, pump the concrete mixture and move freely as a truck. The whole power system is controlled by the power engine.
The engine drives the hydraulic pump to move the piston, becoming mechanical energy to pump ready mixed concrete, and then the finished concrete mixture will be continuously transported through the placing boom to a certain height and distance.
Its max vertical distributing height can reach 38.7 meters, and its max distributing depth can reach to 27 meters. In other words, its pumping capacity can satisfy the construction for most projects, such as high-rise buildings construction, medium-sized and small-sized construction, rural houses construction, commodity building construction, villa group construction, and residential buildings construction.

The Advantages of Aimix Concrete Pump Truck for Sale in Sri Lanka
- Aimix sets up the operating arm and switches in one operation board which helps to improve their handleability greatly.
- Aimix uses concrete cylinder with 200×1400 mm diameter for our pump machines. Bigger volume will reduce the switching times for the slide valve while the pump delivery outputs are same. That means great improvement has been brought to lengthen the service life of slide valve. According to the data, Aimix slide valve presents 1.27 times the service life of other brands.
- Aimix adopts V-type direct-injection engine with eight cylinders. Our engines decrease the fuel consumption around 15-20%. With the help of discharge control lever, the hydraulic oil stays at 160 liters while the engine is running. That is where we reduce the fuel charge.
- In the pump, Aimix equips with flashboard type slide valve of 200 mm diameter for better long distance pumping concrete.
