Forklift Pneumatic Tires

Quick Details

How long can a forklift tire be used normally?

1, In a certain load and driving conditions, the forklift tires have a suitable tire pressure, the test shows that when the tire pressure is lower than the standard value of 20% -25%, a corresponding increase in fuel consumption by 20%. When the tire pressure is higher than the standard value of driving, so that the center of the crown crown, tire and road contact area decreases, the unit area of the load increases, the central wear of the crown increased. Tire cord by excessive stretching, carcass cord stress increases, cord fatigue process to speed up, causing the cord pull off, resulting in tire early puncture.

2, In a certain load and tire pressure, the speed increases, the tire deformation frequency, the carcass vibration and tire circumferential and lateral distortion (the formation of static waves) increases, the unit time due to friction generated by the increase in heat , Tire performance degradation, and even the emergence of ply rupture and tread peeling phenomenon, to speed up the tire wear and damage.

3, Under a certain tire pressure, the tire overload to increase the flexural deformation, cord and cord stress increases, easily lead to broken parts of the tire wall, loose and curtain fabric delamination, carcass cord force Will exceed the design allowable stress and tire ground pressure, resulting in increased heat, carcass temperature, load capacity decreased. At the same time due to shoulder contact with the ground to produce wear and tear, especially in the face of obstacles, even if a small stone, will cause crown crown blasting. Practice has proved that in the case of turning on the road and the road, when the tire load exceeds 20%, its mileage will be reduced by 35%; more than 50%, shortening 59%; more than 1 times, shorten more than 80%.

4, The road conditions on the tire life is also a great impact, it affects the friction between the tire and the ground and the tire by the dynamic load. When the tires by the grease, acid and alkali material corrosion and long time high temperature effect, the tire physical and chemical properties will change, carrying capacity greatly reduced, the use of extremely puncture. In addition, the oil by the corrosion of the tire will appear clogged block peeling off, the tire appears a small area of rubber off, and the carcass cord and rubber detachment and so on. As the patch can not be compatible with the oil-bearing rubber, so even if the tire damage is very small wound, but also lost the possibility of repair.

5, High temperature will make the rubber tear strength, elongation and hardness reduction, so that the adhesion between rubber and cord strength decreased, but also accelerated the aging of rubber. Due to the aging of the tire wall and cracks and serious deformation of the fetal wall caused by carcass cords and rubber separation, once the tire encountered a sudden load is likely to appear puncture.

6, Due to the distribution of the front and rear bridge load, the drive wheel and the steering wheel of the different operating characteristics and differences in road conditions, the tire wear conditions are inconsistent, if the same bridge on both sides did not replace the same plant, the same size, structure, Pattern tires, it will accelerate the tire wear.

7, In use, if you do not pay attention to a reasonable mix and regular transposition caused by tire load uneven load, also will accelerate tire wear.
