Concrete pump truck is the use of pressure to concrete along the pipeline continuous conveyor machinery. Is composed of pump body and pipeline. In the form of the structure of piston type, extrusion type, the hydraulic diaphragm type. Pump body is installed on the chassis, and equipped with a stable or inflectional placing boom, is composed of pump truck.

It is characterized by fast speed and heavy load, this would require the oil cylinder are often in high voltage, overload, high frequency environment, HOLAM from the customer and understand the working characteristics of the concrete pump truck, combined with the HOLAM in the field of concrete equipment mechanical design experience for many years, through the chromium plating on the inner wall of the cylinder body, coating layer, improve
the wear ability of the cylinder, in the case of continuous operation, greatly improving the service life of the oil cylinder.
