Construction vehicles must control the tire load and control the speed of travel
Release Time：2023-02-02
When the construction vehicle is running, it is necessary to control the tire load, pay attention to the balance of the load, control the speed of travel, and pay attention to the ground conditions.
Construction vehicles should be loaded with materials and items according to the allowable load. Overload operation will greatly accelerate tire damage. The more overload, the shorter the service life. In addition, unbalanced loading can also cause local overload, and in severe cases
It can cause the vehicle to float or even cause the vehicle body to overturn.
The hazards of overloading are manifested in:
1. The deformation of the carcass increases, the heat generation is obvious, the cord is delaminated, and it is easy to explode.
2. The stress of the cord increases and it is easy to break.
3. The tread slips obviously on the ground, and the wear increases.
In addition, the standing wave generated on the surface of the tire crown when the vehicle is speeding will increase the tire temperature and internal pressure sharply. When the driving speed is close to the critical value of the tire, the standing wave frequency is close to the natural vibration frequency of the carcass itself, which directly leads to carcass damage. .
In order to ensure safe and energy-saving driving, the speed of engineering vehicles should be controlled according to the specific environment and actual working conditions. Pay attention to the road conditions on the ground during driving to prevent sharp obstacles from piercing the carcass.
