There are many reasons for the jitter of the truck-mounted flatbed transporter, which may be the axial offset or the unbalanced force of the tire, or the shock absorber. But jitter may also indicate that there are some problems inside the tire; even if the tire is not the root cause of the vehicle jitter, the jitter will damage the performance of the tire and cause tire problems soon.
●Tread pattern depth of tire of truck crane
The thickness of the tread pattern must be greater than 1.6 mm. If you often drive on wet and slippery roads with low friction, it is best to ensure that the tread pattern thickness is twice the above value. You can learn from professionals and buy a gauge to measure the thickness of the tread pattern.
●Tread pattern wear indicator line of truck crane
The new tire has one more humanized design than the old products in the past, the tread pattern wears an indicator line. When the tire is very new or the degree of wear is very low, these indicator lines are hardly noticed, but when the wear reaches a certain level, these indicator lines hidden in the tread grooves appear. The tread pattern wear indicator line is a flat rubber strip that is embedded in the tread gully perpendicular to the longitudinal direction of the tread. When you check the tires and occasionally find one or two indicator lines, it means that the tread pattern thickness has been reduced a lot. In this case, you must be extra careful when driving on slippery roads. If almost all the indicator lines on the tire are clearly visible, it means that you need to replace the tire as soon as possible.
●Crack on the sidewall of a tire of truck crane
The problems on the tires are not all concentrated on the tread, and there are some problems in the sidewall of the tire. Look for the cracks and cuts on the sidewall of the tire that are directly visible to the naked eye. These small grooves indicate possible leaks on the tires in the future, or worse, even cause tire bursts. These tire failures are what we strongly hope to avoid. Therefore, when the tire sidewall cracks seem to be serious, it is better to drive the vehicle to the repair shop as quickly as possible to replace the tire.
●Protrusion and blistering on the tires of the crane truck
In some cases, the outer surface of the tire may not have enough strength, resulting in bumps and blisters that are higher than the normal tire surface. This is like an aneurysm in a blood vessel, and tires face a similar situation. If you fail to send the vehicle to the repair shop in time to detect tire failure, the area with insufficient strength on the tread is likely to cause sudden bursts and drive down at high speed. Bursts of tires can even cause serious injuries to drivers and passengers.
●Excessive vibration and jitter of the crane truck
It is inevitable that a certain amount of jitter occurs when the crane vehicle moves forward, especially under poor road conditions. When you have certain driving experience, you can judge by yourself what kind of jitter is within a reasonable range, and what kind of jitter indicates that the vehicle is malfunctioning.
There are many reasons for vehicle jitter. It may be that the tires have an axial offset or unbalanced forces, or there may be problems with the shock absorber. But jitter may also indicate that there are some problems inside the tire; even if the tire is not the root cause of the vehicle jitter, the jitter will damage the performance of the tire and cause tire problems soon. Therefore, if your car has serious jitter, especially on a road with good road conditions, immediately drive the vehicle to the repair shop for inspection.
Drivers of truck cranes should always keep in mind that a greater degree of jitter is often a precursor to vehicle failure.
