Howo Cargo Truck
Composition of Howo Cargo Truck
- Howo Cargo Truck is composed of vehicle chassis, mixing cylinder, transmission system, water supply device, full power extractor, front and rear support of mixing cylinder, reducer, hydraulic transmission system, feeding and discharging system, manipulation mechanism and other parts. Due to the technical bottleneck, domestic mixer trucks with tank volume of 3m³-8m³ adopt the four major parts from China, while most of the four major parts adopted for the volume above 8m³ are imported parts.
- The mixer truck is composed of: second class chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, operation system, human ladder and other parts. The front end of the mixing tank is connected to the reducer and mounted on the front platform of the frame, while the rear end is supported by two pallets mounted on the back of the frame through the raceway.

Working principle of Howo Cargo Truck
The Howo Cargo Truck is The power is transmitted to the hydraulic pump through the transmission shaft. The hydraulic pump generates hydraulic energy and transmits it to the hydraulic motor through the oil pipe, which converts the hydraulic energy into kinetic energy and transmits it to the mixing tank by decelerating and increasing the torque through the reducer.
Special Agency Of Howo Cargo Truck
Power take-off device
- It mainly consists of the mixing cylinder and its auxiliary support parts. The mixing cylinder is the concrete loading container, it is made of high quality wear-resistant thin steel plate, in order to be able to automatically load and unload the concrete, its inner wall is welded with a special shape of spiral blades. The concrete moves along the spiral direction of the blades during rotation and is mixed and stirred in the process of continuous lifting and turning. During feeding and transporting, the mixing cylinder is turned forward and the concrete moves inwards along the blades, while during discharging, the cylinder is turned backwards and the concrete is discharged outwards along the blades. The rotation of the mixing drum is ensured by a hydraulic drive.
- The loading capacity is 3 to 6 cubic metres. For concrete mixer trucks with a loading capacity of 3 to 6 cubic metres, the hydraulic pump is driven by the car engine through the power output shaft, and then the hydraulic motor is driven by the high pressure oil. The blades are the main components in the mixing unit and damage or serious wear will lead to uneven concrete mixing. In addition, the angle of the blades, if not designed properly, can cause the concrete to segregate.

Maintenance and repair of Howo Cargo Truck
As a transport vehicle, the concrete mixer truck must be maintained and repaired in accordance with the provisions of the Ministry of Transport’s Order No. 13 of 1990, which stipulates the maintenance system of “regular inspection, mandatory maintenance and repair as appropriate”. Under this premise, the actual situation of concrete mixer trucks should be combined with the maintenance and repair. In terms of daily maintenance, in addition to the regular maintenance of the engine and chassis of the vehicle, the following maintenance work must be carried out on the concrete mixer truck.
As concrete can set hard in a short time and is corrosive to steel and paint, washing the concrete adhering to the concrete storage tank and inlet and outlet after each use is a serious daily maintenance task that must be carried out. This includes
- Flushing the inlet with water before each filling so that the inlet remains wet during filling.
- Filling the water tank supplied with the truck with cleaning water while loading.
- Rinse the inlet after loading to wash away any residual concrete in the vicinity of the inlet.
- After unloading at the site, rinse the discharge chute and fill the concrete storage tank with 30-40 L of cleaning water; keep the concrete storage tank rotating at a positive and slow speed during the return journey.
- Remember to drain the concrete tank before the next loading.
- Thoroughly clean the concrete storage tank and the area around the inlet and outlet at the end of each day to ensure that no cement or concrete lumps are stuck.
All of the above work can cause great problems in the future if not carried out carefully at one time.
After-sales maintenance of sinotruk howo cargo truck
- Reasonable determination of the protection cycle. The car protection cycle refers to the distance mileage or work of car protection. The owner should refer to the protection cycle recommended by the car manufacturer in the process of practical use, and make appropriate adjustments to the protection cycle in relation to the car’s own skills and operating conditions. Generally speaking, new cars are used under superior road conditions, without too frequent protection, with the manufacturer’s rules as the upper limit of the protection cycle can be; while the car’s skills are poor, or use the premise of poor, should be appropriate to shorten the protection cycle.
- Adequate application of free testing. Concrete mixer manufacturers to carry out free testing campaign for the owners of long and short benefits, owners can apply these testing campaigns to like the car for a specific physical examination, real-time discovery and eliminate some potential problems, and then save the future can present high maintenance and protection costs.
- As far as possible less breakdown repair assembly. A good number of concrete mixer owners have this feeling, like a car of a certain assembly in the collapse of the repair will not be able to pick up, so that the vehicle prematurely into the maintenance period. The reason for this phenomenon is the assembly skills of the repairer and the quality of the parts. Thus, it is best to prevent the collapse of the repair assembly, the application of various types of advanced skills protection equipment and tricks, the car free of dismantling protection, in order to prevent the formation of the car assembly and parts of unnecessary damage, progress in the quality of protection, and then reduce the total cost of maintenance.
The role of the drive unit is to drive the rotation of the concrete tank, which consists of the pickup, universal shaft, hydraulic pump, hydraulic motor, manipulation valve, hydraulic oil tank and cooling device. If this part stops working due to a fault, the concrete storage tank will not be able to rotate, which will lead to the scrapping of the concrete in the vehicle, or in serious cases, even the whole concrete tank will be condensed in the tank, resulting in the scrapping of the concrete mixer truck. Therefore, the reliability of the drive unit is an issue that must be given high priority in use. To ensure that the drive unit is intact and reliable, the following maintenance work should be done.
- The universal rotating part is a fault-prone part, it should be greased on time, and the wear and tear situation should be checked frequently and repaired and replaced in time. The fleet should have a spare universal shaft assembly to ensure that once a failure occurs it can resume work within a few minutes.
- Ensure that the hydraulic oil is clean. Concrete mixer trucks work in a harsh environment and must prevent sewage and mud from entering the hydraulic system. The hydraulic oil should be changed regularly according to the requirements of the operating manual. Once the hydraulic oil is found to be mixed with water or mud during inspection, the hydraulic system should be stopped immediately to clean and replace the hydraulic oil.
- Ensure that the hydraulic oil cooling device is effective. To regularly clean the hydraulic oil radiator, to avoid the radiator is blocked by cement, check the radiator electric fan operation is normal, to prevent the hydraulic oil temperature exceeds the standard. Hydraulic part as long as to ensure that the hydraulic oil is clean, general failure is not much; but different manufacturers, the service life is not the same
