Brief Introduction: Dongfeng Series concrete mixer truck adopts
European modern style, featuring attractive appearance, rational
structure and stable performance. Different steel materials for
different parts of tank body, which is made from famous steel
factories. Service life is 1.5 times than average.
Adopt CNC plasma equipment and leading international fixtures,
ensure the accuracy of the parts manufacturing key weld using CNC
automatic welding production lines to ensure the weld strength.
Modular design and assembly lineperation process; Painting work
uese luxury coach paint process of industry leading technology,
effectively guarantee the quality of the vehicle. Processing
Technology: (1).Blanking process Drum and mixer are processed with large scale numerical control
plasma cutting machine, numerical control punch, the equipment
brings less errors and high precision, ensure the product geometric
accuracy and increase production efficiency as well. (2).Welding process Dongfeng Group holds the leading welding quality in national same
industry. The mixer drum is shaped with special hydraulic roller.
The unique central axis orientation tooling ensures concentricity
and roundness of the drum. The key process use the digital welding
machine, automatic welding, which make the weld joint at high
quality. (3).Painting Process: Tank body was pre-treated with shot blasting in order to remove the
rust and eliminate welding residual stress inside structure.
Further it can improve surface intensity and painting adhesion, lay
a sound foundation for painting. Painting adopt luxury bus coating
process and use Dust-free spray paint and baking process both
finish paint and anti-rust capacity are the first class in the same
factory. And it’s the only industry who use the coach coating
process for engineering vehicles. (4).Assembly Process: Rational assembly process layout, strict quality control system,
guarantee-tees excellent production and increased production
ability. All hydraulic systems are adopted with international top
brand products, assembled under enclosed environment, to ensure
clearance in the hydraulic system. (5).Inspection and Testing Process: After adjustment and test, all vehicle products will be conducted
with compulsory inspection on front wheel sideslip, lamps, brake
system and other items on the automatic inspection line, to ensure
reliability and safety. Control System: Adopt three-point control mode, that is, by control bar on both
rear side and in-cab device to control and drum easily and
conveniently. Features: (1).Control System: Adopt three-point control mode, that is, by control bar on both
rear side and in-cab device to control and drum easily and
conveniently. (2). Hydraulic System: Adopt international top brand in hydraulic driving field, such as
Germany, Italian, American Brand with Integral structure, excellent
performance, meeting customers’ various special need. (3).Water supply System: Have various volume water tanker, can feed the water for mixing and
cleaning, enlarged water pipe and various feeding solution. Can
convenient customer, water feeding solution can use air pressure,
reducer pump, electronic pump ect, can meet different requirement. (4).Blade anti-wear Protection: Modified logarithmic helical curve type of blade. In light of
special need of wear resistance, all blades are mounted with
anti-wear protection parts, not only prolonging vehicle service
life, but also synchronizing the wear of drum and blades. (5).Blade Process: Blades are made of special cold-forming processing molder, welded
with drum body by new welding process without obvious trance.
