The concrete mixer truck is composed of a second-class chassis, a transmission system, a hydraulic system, a frame, a mixing tank, a feeding, and discharging device, a water supply system, a control system, a ladder, and tires. The front end of the mixing tank is connected with the reducer and installed on the front of the frame, and the rear end is supported by two rollers installed on the back of the frame through the raceway. Next, let's take a look at the maintenance of concrete mixer truck tires.
Here is the content list:
l Tire load
l Tire temperature
l Chassis condition
l Air pressure must be up to standard
l Tread free of cracks
l Avoid sudden braking
l Control the speed
l Don't splash water to dissipate heat
l Road conditions
l Frequently check the spare tire
There is no doubt that the greater the load on the concrete mixer truck, the shorter the life of the tire. Especially in the case of overloading, it is more prominent. The tires produced by regular tire manufacturers are all marked with load index. Tires should be used within the maximum load capacity corresponding to the specified load index.
During the driving process of the concrete mixer truck, the tire temperature rises due to stretching, compression, and friction. Excessively high temperatures are likely to aggravate tire wear and even puncture.
The parallelism of the front and rear axles, the four-wheel alignment, the working condition of the braking device, and the technology and condition of other parts of the chassis will affect the life of concrete mixer truck tires to varying degrees. Once a serious traffic collision occurs, the owner must drive the concrete mixer truck to a professional maintenance station for chassis inspection and adjustment.
Concrete mixer truck drivers should inflate the tires according to the manufacturer's regulations. When the tire pressure is lower than the standard value, the wear of the tire shoulder increases sharply. When the tire pressure is higher than the standard value, the wear of the middle part of the concrete mixer truck tire tread increases due to the reduction of the tire contact area and the increase of the unit pressure. At the same time, the rigidity of the concrete mixer truck tire is increased, so that the dynamic load on the concrete mixer truck wheel is increased, and it is easy to cause the carcass to burst
Regularly check the concrete mixer truck tire surface for cracks, deformation, and other defects. The tread grooves of concrete mixer truck tires gradually become shallow due to driving wear, and if they are worn out, they will lose their functions such as drainage and anti-skid. The performance of the concrete mixer truck will be greatly reduced, and the seemingly small cracks are a hidden danger of tire blowout when driving at high speed. In addition, pay attention to removing small stones in the groove in time.
Do not start too fast, and avoid frequent use of brakes and emergency brakes, so as not to accelerate tread wear due to the dragging of 6x4 concrete mixer truck tires and the ground. Master the appropriate speed and pay attention to the dynamics of the road, pedestrians, and vehicles, prepare for braking, reduce frequent braking, and avoid emergency braking. Thereby reducing the tire wear of concrete mixer trucks. When faced with unavoidable broken glass or other foreign objects, slow down and pass, and never brake suddenly. Because of the increased pressure caused by sudden braking, glass shards, and foreign objects are more likely to get stuck in concrete mixer truck tires.
Concrete mixer truck turning should be based on the curved road conditions and turning radius, and generally slow down appropriately, so as not to accelerate unilateral tire wear due to inertia and centrifugal force. When a concrete mixer truck goes downhill, it should be based on the size, length, and road conditions, Control the appropriate vehicle speed, to avoid or reduce the use of emergency braking and reduce tire wear. When the 8x4 concrete mixer truck stops on the way and stops at the station, it should develop the habit of safe taxiing.
Concrete mixer truck tires tend to overheat when driving for a long time or at high speed in summer, and the air pressure increases at the same time. At this time, stop the machine to dissipate heat, and it is strictly forbidden to deflate and reduce pressure or splash water to cool down, to prevent abnormal aging of tread rubber.
If the concrete mixer truck is driven on gravel roads or in bad road conditions for a long time, the service life of the tires will be reduced. This is no exception for off-road tires.
In the maintenance and use of concrete mixer truck tires, don't forget the most important tire: the spare tire. The spare tire is equipped by the manufacturer, but it is often forgotten by the car owner and lacks maintenance. It is recommended that you check the spare tire regularly every 3 months, and inflate it if necessary, so as not to find that it is flat when you need it.
