Right now, there are more and more second-hand concrete mixer trucks on the market. And many customers tend to invest a used one to finish his project. But in fact, used truck is not so good as new one. So buying a new concrete mixer truck sale will be your ideal choice, if you want to produce quality concrete, save cost, labor and reduce production time. New cement truck for sale is a special vehicle, which is used to deliver concrete for construction project. The concrete mixing device is installed on the chassis, during the transportation of concrete, the device will mix and stir concrete at the same time and prevent disintegration and solidation. This new truck is unique because its six advanced manufacturing processes: raw materials discharging and tank body molding; center positioning tooling; process of shotblast pretreatment; bus coating process; dust-free spray paint and reasonable assembly process layout. This page will tell you the advantages of buying a new concrete mixer truck, and tell you the basic information about it. Hope you will find a proper truck for your construction project.
Advanced manufacturing processes of New Concrete Mixer Truck Sale
1. Raw materials discharging and tank body molding. Key parts such as mixer drum, blades, front and back adopt CNC discharging, ensure the discharging accuracy; welding of cylinder panel veneer is conducted at the dedicated work platform, and adopt special automatic welding equipment to weld.
2. Center positioning tooling. Combination of tank body uses special fixture, adopts the only domestic location of the pit center, which can effectively ensure the coaxiality and circular degree of the concrete drum. The welding adopts panasonic automatic protection welding machine. What’s more, center positioning tooling of cylinder has been declared national patent: ZL200820069837.1.
3. Process of shotblast pretreatment. Cement drum, auxiliary girder, water tank, feeding and discharging system as well as the other accessories adopt automatic shot blasting pretreatment process, which achieves oil removal and rust removal, greatly increase the adhesion of coating and ensure the spray paint quality.
4. We adopt bus coating process, spray the primer on the mixer truck, scrape the atom-ash, spray and dry the coating on each coating.
5. Dust-free spray paint. The whole concrete agitator adopts dust-free spray paint and baking varnish process treatment, paint quality and anti-rust ability surpass the competitor.
6. Reasonable assembly process layout and strict quality control system provides a guarantee for production capacity. Hydraulic system adopts special airtight environment for installation, ensure the cleaning of hydraulic system. Professional technician will check the whole new concrete mixer trucks for sale and ensure they can meet the requirement of technology. After the check, there will be an inspection for axle load, braking, lamplight and ensure the product quality and security.
Chassis structure of new concrete mixer truck sale
1. The cab. A place where the driver works.
2. Engine. The power supply center of the new concrete agitator.
3. Transmission system. Transfer the power of engine to ride wheels, mainly includes clutch, speed changing box, transmission shaft, drive axle, etc.
4. Steering system. It is used to ensure the truck can travel in the direction of the driver’s choice, and it is made up of steering wheel and transmission device.
5. Braking system. The function of it is decelerating and stopping the truck, each truck has several independent braking system. Braking system consists of energy supply system, control device, transmission system and brake.
Classification of chassis
Concrete mixer truck manufacturer usually classifies the chassis according to brand and driving form.
1. According to the brand, there are mainly Jiefang, Dongfeng, Shaanxi, Sinotruk, Fukuda and C&C Truck. For instance, CA represents Jiefang, DF represents Dongfeng, SX represents Shaanxi, ZZ represents Sinotruk and BJ represents Fukuda.
2. According to the driving form, there are mainly 4×2、6×2、6×4、8×4. Take 6×4 for an example, 6 means there are 6 vehicle wheels, 4 means there are 4 driving wheels. And double tires are regarded as a wheel.
There are two ways of power takeoff: engine torque extraction and diesel engine power extraction.
1. PTO is such spare part used to supply the power for high-pressure oil pump, and achieve the mixing of mixing cylinder, which is one of the most important part of chassis structure in new concrete mixer trucks.
2. Diesel engine power extraction will not be limited by the chassis engine and it is widely used in semi-trailer concrete mixer.
Other parts of new concrete mixer truck sale
1. Hydraulic pump. Transfer the mechanical energy passed by additional transmission shaft to liquid pressure energy, and then transfer to the hydraulic motor. Main brand are Italy PMH and ARK, etc. Output volume is 89 or 90 ml.
2. Hydraulic motor. Transfer the liquid pressure energy passed by hydraulic pump to mechanical energy, and then transfer to the reducer. Main brand are Italy PMH and ARK, etc. Output volume is 89 or 90 ml.
3. Reducer. Decelerate the high speed power passed by hydraulic motor and transfer it to the mixer drum and achieve the mixing of mixer drum. Main brand are Italy PMB and TOP, German ZF, torque is 75000 or 80000N.m, etc.
4. Tank body of new concrete trucks for sale. It is also named cement drum, is used to load concrete mixture. When it rotates, concrete will move along the spiral direction of the blades, when the mixer drum rotates clockwise, concrete will move along the inner direction of the blades, when discharging materials, mixer drum rotates anticlockwise, and concrete will be discharged out along the outside direction of the blades.
5. Water supply cleaning system. Its main function is to clean the mixing cylinder and prevent the concrete will be adhesive to the inner wall of mixer drum. There are two types of cleaning device: pneumatic-typed and water pump, we usually use pneumatic-typed. Moreover, main waterway adopts overpressure resistant and beautiful polyethylene-aluminum composite pipeline.
6. Feeding and discharging system is composed of feeding hopper, discharging hopper, swivel gear and main channel. Q345 cold-resistant steel sheet forming, high wear resistance and attractive appearance, feeding hopper can meet 3m³ feeding demand. The main channel can be lifted, it can achieve 180 degree rotation.
7. Joystick in cab. Rotating direction and speed of the cylinder can be adjusted according to the need.
Control joystick of the both sides of tailstock. Simple operation, it is with locking device, during the process of transportation, which can effectively prevent the fault of mixer drum and ensure the quality of concrete.
