With the rapid development of industry, more and more forklifts have joined the transport force. Industrial materials can be as light as a hundred catties or as heavy as a thousand catties. Choosing pneumatic tires is likely to have the risk of puncture and broken tires, and it is time-consuming and laborious to repair the pick-up tires. For the heavy labor, choosing solid tires with all-rubber structure will help save a lot of time and cost.
After using the forklift with solid tires for a long time, I find that the pattern is flattened, and I worry about whether the forklift tires can still be used? The following is the answer from the solid tire manufacturer.
The main function of the tire pattern is to increase the friction between the tread and the road surface to prevent the wheel from slipping, which is the same as the sole pattern. The tire pattern improves the ground contact elasticity of the tread. Under the action of the tangential force (such as driving force, braking force and lateral force) between the tread and the road surface, the pattern block can produce greater tangential elastic deformation. As the tangential force increases, the tangential deformation increases, and the "friction effect" of the contact surface is also increased, thereby suppressing the slipping or slipping tendency of the tread and the road surface. This largely eliminates the shortcomings of non-patterned (light tread) tires that are easy to slip, making the car performance related to the friction between the tire and the road surface-dynamic, braking, steering and driving safety There is a reliable guarantee for normal performance. Studies have shown that the factors that produce the friction between the tread and the road surface also include the adhesion between the two surfaces, the effect of molecular gravity, and the micro-cutting effect of the small-size micro-protrusions of the road surface on the tread. However, the main role is still Elastic deformation of the pattern block.
Forklift solid tires are composed of three-section rubber, supported by high-rigidity, high-strength base rubber and steel rings, which not only ensure the stiffness of the tire, but also ensure the tightness of the tire and the rim, and fundamentally eliminate the slippage of the solid tire. Ring problem; the highly elastic intermediate rubber effectively absorbs the vibration generated when the vehicle is running, has comfortable driving and avoids damage to the vehicle; the thicker tread rubber layer ensures the tire's tear resistance Abrasion performance improves the service life of solid tires; the tire crown is the tread pattern part, which is processed by natural rubber and has super abrasion resistance, toughness and elasticity. It is the main contact part to ensure the normal and safe operation of the vehicle. , There are obvious safety lines at the transition part of the tread block and the carcass. Generally, the tires can be replaced when they are worn to the position of 0.1-1CM on the safety line. At this time, the tread pattern should be nearly flat, and the tire grip will be significantly reduced. There are potential safety hazards such as skidding and failure to stop the car. At the same time, the elasticity of the tires will be obviously insufficient, which will increase the body turbulence, and the damage of the front and rear axle shells will increase maintenance costs.
