2019 New Style Small Concrete Mixer Truck - 38 meter concrete mixing pump truck – Changyuan Detail:

1.Truck Mounted Concrete Pump 38m One button stabilization technology

No matter how much vibration the boom incurs after being moved, only one button can make the boom stop steadily and immediately. Meanwhile, the terminal hose will exercise quick and precise positioning.

2.Truck Mounted Concrete Pump 38m Boom anti-vibration technology

Effectively mitigate the boom jittering during the pumping process, with amplitude of vibration decreasing by 50%, and the terminal hose is running steadily.

3.Truck Mounted Concrete Pump 38m Anti-swing control technology

Adopt the brand-new rotary braking technology, and the boom’s rotary swing amplitude decreases by 60%, which helps realize unprecedented precise braking.

4.Truck Mounted Concrete Pump 38m Energy-saving technology

With reversing times hitting 29 times/minute (when the system pressure is 12MPa). Pumping efficiency, an increase of up to 25%, and fuel consumption, a decline of up to 10%. Truck Mounted Concrete Pump 38m Energy-saving technology High wear-resisting parts

Delivery pipe

Straight tube, hinged elbow, and, large elbow, and small elbow all adopt the double-layer compound structure. Inner layer is extremely wear resistant, with service life hitting 50,000 m 3.

Discharge port / transition bushing

Adopt the double-layer compound structure, of which, the inner bushingis made of special steel whose wear resistance is 15 times that of ordinary steel, with service life hitting 60,000 to 80,000 m 3.

Concrete piston

Ttakes rubber as the substrate, and on its exterior layer there is compound wear-resisting fabric, which is extremely resistant to pressure, heat, and abrasion, and applicable to different severe working conditions, with service life hitting 25,000 to 30,000 m 3 .

Wear plate/cutting ring

Adopt special inlaying process, with connecting strength surpassing 100MPa. Of which, the wear plate’s service life is up to 50,000 to 60,000 m 3 , and the cutting ring’s service life hits 20,000 to 30,000 m 3 .

Delivery cylinder

The inner layer is plated with chrome with thickness of above 0.3mm, and so its hardness exceeds HV900, with service life hitting 100,000 to 140,000 m 3 .
