    What is the difference between polyurethane tires and rubber tires?

    Rubber tires have shortcomings such as short service life, poor wear resistance and tear resistance during use, especially truck tires, which often lead to punctures due to their limited load-bearing capacity. The investment cost of rubber tire production equipment is very high, and some processes need to be manually operated. Even with very advanced molding equipment, the manufacturing quality and the quality of each batch of products cannot be completely uniform. In addition, rubber tires will generate a lot of waste during the use process, and it is very difficult to recycle and reuse them after they are scrapped, which is likely to cause environmental pollution. Polyurethane elastomer is the most wear-resistant elastomer at present, with the advantages of high wear resistance, colorability, high cutting resistance, excellent oil resistance and chemical resistance. Polyurethane tires are more uniform than rubber tires and do not suffer from tread peeling. Cut high temperature.

    What is the replacement standard for forklift tires?

    Depending on the rubber compound of forklift tires, the vehicle environment and driving habits, the service life of forklift tires will also vary. Generally, forklift tires with a groove depth of less than 1.6 mm can no longer be used, because the drainage performance and puncture resistance of forklift tires will be greatly reduced at this time. In addition, if a forklift tire has been repaired three or four times, the forklift tire can be swapped to a non-drive or rear wheel to reduce the risk of a puncture. The service life of forklift tires is different from the environment and usage methods of different use sites. The details are as follows: 1. Under certain load and driving environment conditions, the forklift tires have a suitable tire pressure. When the forklift tire pressure is higher than the standard value, the tire crown is grounded in the middle, and the contact area between the tire and the road surface is reduced. The load increases, and the wear of the middle of the crown increases. The cord of the tire is overstretched, causing the cord to break, resulting in an early tire blowout. 2. Under normal load and tire pressure, the increase in vehicle speed will cause the deformation frequency of the forklift tire, the vibration of the carcass, and the circumferential and lateral twisting deformation of the tire (forming static waves) to increase. Heat increases. The working performance of forklift tires decreases, and even ply rupture and tread peeling occur, which accelerates tire wear and damage. 3. Road conditions also have a great influence on the service life of the tire, which affects the friction between the tire and the ground and the dynamic load on the tire. 4. High temperature will reduce the breaking strength, elongation and hardness of the rubber, reduce the adhesion strength between the rubber and the cord, and also accelerate the aging of the rubber. Due to the aging of the sidewall rubber and the cracks and the severe deformation of the sidewall, the carcass layer cords are separated from the rubber. Once the tire encounters a sudden load locally, it is likely to have a puncture.

    What are the maintenance guidelines for industrial forklift rubber solid tires?

    When it comes to forklifts, most people will think of the operation of forklifts. Forklifts are very large and heavy transport vehicles, and forklifts have very high requirements on tires. There is a saying in the tire industry: "Three points of use, seven points of nourishment", so how to maintain the rubber solid tires of industrial forklifts to prolong their life? Zhejiang Kunrong Rubber Technology Co., Ltd. Let me tell you how to maintain the rubber solid tires of industrial forklift trucks.1. Rubber tire selectionIt is very important to choose a suitable and correct forklift solid tire. Different types and patterns of tires must not be mixed arbitrarily due to the actual size and load capacity of each tire.Rubber solid tiresIn addition to the need for air pressure maintenance of pneumatic tires, there is no safety/safety hazard caused by tire blowouts. High-quality/high-quality solid tires are much better than pneumatic tires in many aspects, such as cost performance, maintenance-free and longer replacement cycle. Tires: Under the working conditions of moderate working strength, distance and load, solid tires with side holes with higher shock absorption effect are a good choice for better consideration of safety/safety and comfort/comfort.For forklifts that carry out handling operations in a clean room, it is recommended that you choose light-colored solid tires without imprints, which can greatly reduce the obvious black marks left on the ground when the forklift is transporting loads, especially when turning, stopping and braking.2. Pay attention to the load indexForklift solid tires should be within the specified load indexUse within the corresponding load capacity. It goes without saying that the heavier the load on the vehicle, the shorter the life of the tires. Especially in the case of overload, it is more prominent.3. Pay attention to speed levelsForklift solid tires should be used within the travel speed corresponding to the specified speed class index. The tires produced by regular solid tire manufacturers are marked with a speed level index.4. Avoid high temperature road conditionsExcessive temperature can easily aggravate forklift solid tire wear and even puncture. When the vehicle is running, the tire temperature will rise due to the expansion, compression and friction of the tire.5. Timely replacementTimely transposition of forklift rubber solid tires, selection of appropriate tread patterns, daily maintenance, regular inspections, timely repairs, and frequent digging of stones and foreign objects in the tread patterns are all important factors to prolong the life of the tire.6. Regular inspectionWatching for early signs of tire damage can prevent unnecessary tire changes. Check your tires at least once a week. Check items are:1) Whether the tire surface has metal chips, broken glass or other impurities that can cause early damage to the tire;2) Check whether there are slight cracks in the tire rubber, early delamination and block loss, to avoid accidents and unnecessary maintenance costs. If found, please remove them in time before use In many cases, don't wait until there is a fault before driving to the repair station for maintenance. Regular maintenance of the vehicle is also closely related to the extension of the life of the rubber solid tires.

    How can forklift tires reduce wear?

    Frequent replacement of forklift tires is not a good thing. It is not only time-consuming but also causes a lot of waste. So Zhejiang Kunrong Rubber Technology Co., Ltd. hereby reminds you to use forklifts reasonably, which not only saves time and effort, but also ensures long-term safety/safety work. A guarantee, let's take a look: How to reduce the wear of forklift tires? 1. Strengthen the maintenance of tires.Do a good job of land survey and pressure cleaning, check the temperature of the tires, and the grounding holes are blocked.Usually when inflating tires, if it is cold and under a certain load, regularly check and adjust the tire pressure at least once a month; in summer, due to the high ambient temperature, if the tire temperature is too high, reduce the frequency of increase to avoid strong sunlight to the tires , it is recommended to stop in the shade of a tree, instead of directly pouring cold water for cooling or directly venting to reduce pressure. If you are going to leave it in the open parking lot for a long time in winter, you should base it on the tires and don't start accelerating immediately until the tires get hot, and then it becomes normal driving. 2. Improve driving skills.Lift the clutch pedal slowly and steadily when starting off. The maximum speed of driving must not exceed the speed limit of the tire; it should be avoided as much as possible during the process of rapid acceleration, emergency braking and sharp turning. In the case of obstacles such as rocks and potholes, it is recommended that you slow down as much as possible or avoid it directly.3. Improve the maintenance of the chassis.Lubricate and adjust the design value of wheel hub bearing, tie rod ball end, king pin bushing in time according to regulations; keep the balance of the tire, if it is unbalanced, the wheel dynamic balance test should be used to exhaust the one-way valve frequently, and the tire has been oiled. Once the forklift is found Tire into oil, you should immediately remove the tire to clean, and check the air seal at the same time, replace the tire winter tire in the greenhouse to restore / restore elasticity / elasticity, load the rim forklift tire product Apply soap in the fetal port to prevent damage to the port; pivot oil Sealing and brake hydraulic cylinders should be leak-free, and oil- and wet-resistant rubber tires should meet the requirements for lateral and radial swinging wheel assemblies.

    Why use solid tires for forklifts?

    1. Excellent safe use performance is conducive to improving work efficiencyBecause the solid tire carcass is made of all rubber, the puncture resistance of the tire is ensured to the greatest extent, and the hidden danger of tire puncture during the load-bearing operation of industrial vehicles and in the harsh working environment is fundamentally eliminated. The load-deformation of solid tires is small, and the running stability is good. Because of its puncture resistance and tear resistance, it does not need to be inflated. It avoids the heavy labor of frequent tire replacement and can improve the utilization rate and work efficiency of the vehicle. It can run at low speed and efficiently. In vehicles, solid tires can completely replace pneumatic tires.2. Reasonable structural design to ensure that the tire has better performanceThe solid tire adopts an advanced three-stage structure design, and the three rubber materials respectively ensure the overall performance of the tire. High-rigidity, high-strength base rubber and steel ring support not only ensure the stiffness of the tire, but also ensure the tightness between the tire and the rim, and fundamentally eliminate the slip ring problem of solid tires; the high-elastic intermediate rubber effectively It absorbs the vibration generated when the vehicle is running, and has a comfortable driving performance, while avoiding damage to the vehicle; the thicker tread rubber layer ensures the tire's resistance to tearing and abrasion, and improves the service life of the solid tire;3. Advanced technology and formula designThe production of solid tires has advanced technology with more than half a century of production history and experience. The rubber formula design has maximized the performance of the tires, especially the base rubber is all imported high-rigidity, low-heat-generating rubber materials. The heat generation and temperature rise during operation are minimized, while the heat resistance of the tire is improved, thereby solving the serious problems of solid tires such as swelling, slippage, and burst caused by temperature rise; advanced formula design reduces the tire The rolling resistance. Tested by the National Construction Machinery Quality Supervision and Inspection Center, the coefficient of rolling resistance of solid tires is equivalent to that of pneumatic tires, which solves the problem of increased fuel consumption caused by changing to solid tires;4. Avoid vehicle tire blowouts and out-of-control dangers, and promote safe productionPneumatic tire rim-type solid tire is a solid tire that can be used interchangeably with pneumatic tires of the same specification. When the vehicle is driving at high speed, such as the tire hitting potholes and other obstacles, the tire will be severely squeezed and deformed between the obstacle and the rim flange, which can cause the carcass cord to break, and the compressed air inside the tire will break. The line is pushed up to form a bulge. In more serious cases, it will cause the tyre to rupture, and it will be completely flattened instantly and the vehicle may lose control. Compared with pneumatic tires, it has the advantages of high safety, puncture resistance, tear resistance, wear resistance and long life. It is an ideal replacement product for pneumatic tires in the field of industrial vehicles. With the development of industrial vehicles and the improvement of solid tire production technology, this type of tire has been used more and more widely.
