BRIEF INSTRUCTION

Dawin Small concrete boom pumps are competitive products. It is high reliability, high efficiency, high security, high durability at an organic whole, which with reasonable matching on Chassis, power, electrical, hydraulic, pumping system. Jib structures are flexible, support legs occupy small space, the trucks move easily, safe and stable, the vehicle is 2300mm or 2350mm wide with perfect passing ability.

Chassis and power system of Small Concrete Boom Pump:

chassis is SINOTRUCK or DONGFENG brand,strong carrying capacity,good dynamic performance and low fuel consumption.Emission system is up to National IV standard, low noise and easy to repair.

Jib structure system of Small Concrete Boom Pump:

1.jib structure system is based on the finite element analysis,dynamic analysis and test,and the accurate date support. High strenth low alloy steel plate,all materials and welding line by 100% non-destructive technology ensure the jib structure reasonable and highly reliable.

2.”R” type arms with speed stepless adjustment,pressure compensation and load sensing proportion control syetem ensure the arm running freely and excellent operating performance.

Electric System

Main electric elements are Schneider and LS Brand,the reliability of electric-control is highly improved.

Hydraulic System

Equipped with specially-made valves:large folows,little energy consumption and light impact;ensuring longer service lives.

Power System

We Adopts original LOVOL and YUchai diesel engines as the power of the pumps,effective power.

Main Oil Pump

The main oil pump apply German HAWE,Rexroth series and Japanese Kawasaki Series.

Jib Structure

High strength low alloy stell plate,all materials and welding line by 100%non-destructive flaw detection.

Hopper Device

The Hopper is capacity-increased,coupled with fence and equipped with vibration motor to meet concrete pumping.

Jib System

Electro-hydraulic and manual multople valves ensure wireless remote control and manual control in emergency.

Remote Control

Effective error-proof operation control design ensures the system more reliable and safe.

Centralized lubricating

The lubricant will be injected to the main oil line by the plunger pump and distributed to each lubrication point.
