Do you know the repair tips for forklift solid tires that are degummed or broken?

Do you know the repair tips for forklift solid tires that are degummed or broken?1. Hot patching: File the roughness around the damaged inner tube, stick the fire patch on the damaged area, and make the hole just in the patch, then install the patch clip against the normalizing patch, and tighten it. Press the screw and then ignite the heating agent on the fire repair glue, and wait for 10-15 minutes to bond tightly. 2. When the inner tube is found to have small holes, it can be hot or cold. 3. Outer tire: If the outer tire has cracks, holes, blistering, delamination and other damages, it should be repaired or overhauled according to the specific situation. If there are continuous cracks around the tire carcass, the tread rubber has been polished and there are large holes, the carcass line layer has annular cracks and the whole circle is separated, it should be replaced. 4. Raw rubber patching (cold patching): file rough around the inner tube break, apply raw glue, and then apply secondary glue after the surface of the glue is slightly dry. When the glue is air-dried, attach the prepared raw rubber to the broken On the mouth, pressurize and heat at 140-145 ° C, keep warm for 10-20 minutes to vulcanize the raw rubber, and after cooling, it can be tightly bonded.

Car blowout is so dangerous, why not make it solid?

There are not a few traffic accidents caused by car punctures, especially in high-speed sports cars, the survival rate of accidents caused by punctures is low. Then, some people will ask, since a flat tire is so dangerous, it would be better to make a solid one, and there will be no such thing as a flat tire. Is it really the truth? Our car tires are made of rubber, and the operation is to use the elasticity of the rubber carcass to reduce the impact generated when the wheel turns. If the tires are replaced with solid ones, the cushioning capacity will be greatly reduced, and it is not suitable for high-speed transportation vehicles. And solid tires will damage the road surface and consume much more energy than today's pneumatic tires. Solid tires have no air leakage, and even if the vehicle is overloaded, it will not deform, and it seems to be very simple to use and maintain. Even if applicable, it can only be used for low-speed high-load vehicles, such as industrial loading and unloading vehicles and power vehicles for cargo purposes. The role of tires for vehicles is shock absorption, grip, stability, load-bearing, etc., which can be said to be a very important component. Let's talk about the role of pneumatic tires from the perspective of shock absorption. Pneumatic tires can achieve the effect of shock absorption by generating deformation during operation. To talk about grip and handling, the grooves on the tires have drainage lines, which can prevent the car from slipping, but if the tires are replaced with solid ones, not to mention the waste of materials, various performances will also be greatly reduced. In general, solid tires have many disadvantages, except that they can save the need to check the tire pressure frequently and do not need to be frequently inflated. Therefore, solid tires are not practical, so don't be afraid to use pneumatic tires.

What are the introductions of the handling aids for solid tires?

The carcass of a solid tire is solid. No rope is used as a skeleton, no inflation is required, so no inner tube or seal is required. The early tire company was a solid tire. Solid tires are generally used under high loads, which requires the compound to have sufficient pressure resistance and wear resistance, high modulus stress, high hardness, low deformation, and good wear resistance. Solid tire is an industrial tire suitable for running and managing vehicles under different conditions of low speed and high load. Its safety, durability and economy are obviously better than pneumatic tires. It can be widely used in various electronic industries Social vehicles, military vehicles, construction machinery, towed vehicles in ports and airports, etc. Solid tires often need to be transported during production. Due to the heavy weight of the solid tires used in large vehicles, they cannot be transported manually at all. Therefore, in general, mechanical operations are used. In order to prevent tire surface damage, hooks or chains cannot be used for loading and unloading. At present, many factories use forklifts for loading and unloading, which has low loading and unloading efficiency and high cost. The handling technology of solid tires is used to assist the construction of teaching facilities for classification and handling. The operating system buttons and operating gear levers in the box can be controlled as described above to control the research machine to move to the designated position, and then the turntable rotates and the said control problem according to the control problem. The length adjustment motor starts and develops to drive the front and rear of the cross bar. The application of China Mobile makes the company's fixed plate reach the top of the tire that the company needs to improve handling. Adjust the length of the piston rod of the cylinder through the market to adjust the position of the suction cup to reach the tire. Above the smooth surface of the tread, the hydraulic support rod shrinks so that the suction cup is lowered and adsorbed on the surface of the tire, and then the hydraulic support rod extends to suck up the tire and place it in a designated place.

What is the difference between solid tires and tubeless tires?

The solid tire is a kind of tire corresponding to the pneumatic tire (hollow tire). The earliest tires were solid tires. Solid tires are currently only used for high-load vehicles or machinery that travel at low speeds, and also for machinery in fixed positions. Chinese name Solid tire Foreign name Solid tire Suitable for low-speed high-load vehicles or machinery Classification Bonded and non-bonded features High elasticity, strong heat dissipation, good wear resistance Production of raw materials Precautions for the use and installation of solid tires ▪ Installation of solid tires ▪ Load speed requirements of solid tires ▪ Tire replacement ▪ Storage and maintenance of tires Classification of solid tires Solid tires are generally divided into two types: bonded and non-bonded. The latter refers to the tires that are vulcanized and then fixed on the rim. According to the shape, it is divided into cylindrical solid tire and inclined bottom solid tire; according to the application, it is divided into antistatic, conductive, oil-resistant, high-load solid tire, and environmentally friendly non-marking solid tire. Heavy load v has a strong bearing capacity, suitable for harsh environments, high safety and high elasticity. Mainly used in DUMP TRUCK v Main specifications: 825-20, 900-20, 1000-20, 1100-20 for dock trailers v low rolling resistance, low heat generation, super high bearing capacity, mainly used in dock low flatbed vehicles v main Specifications: 22x8x16, 22x9x16, 22x14x15, 22x16x16 boarding bridge for all-weather use, suitable for various weather conditions, flexible and long service life. Solid tire is a special kind of tire, mainly suitable for special vehicles such as anti-riot vehicles, cash transport vehicles, anti-terrorism vehicles, engineering vehicles, forestry machinery and so on. Solid tires are generally used under high load, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough tensile stress, high hardness, low permanent deformation and good wear resistance. Solid tire is an industrial tire suitable for running vehicles under low-speed and high-load harsh conditions. Its safety, durability and economy are obviously better than pneumatic tires. It is widely used in various industrial vehicles, military vehicles, construction machinery. , towed vehicles in ports and airports, etc. The main raw materials for solid tires are made of a special rubber material. Except for a few hollows in the middle to maintain the center of gravity, all of them are solid. The tires made in this way can be anti-stud, bullet-proof, mine-proof, and incendiary-proof... They are very popular among police officers. But solid tires are very bulky, and the handling is not very good after being installed on the car, so it needs to be further improved by professionals. Solid tires can be divided into non-marking environmental protection type, conductive type, optional type, standard type, oil-resistant type and high-load type according to their use. A. Non-marking environmentally friendly tires: generally light colors, such as white, gray, green, yellow, etc. It is almost close to the ground color of special industries, leaving no or less tire marks during use, keeping the ground clean and tidy.

How are solid tires packaged?

Forklift tires cannot completely ensure that the properties of the tires do not change within a certain period of time after leaving the factory and before the actual installation and application, that is, due to the process of transportation and transportation and possible development, there will be collisions, rubbing, and even some special social conditions. The influencing factor after the material touches is also the wear and tear of the tire's service life. Therefore, we need to analyze the forklift solid tire model when it leaves the factory. The packaging of different research methods, let's take a look at it now: At present, the packaging of tires is usually done by wrapping strips, that is, manually or automatically wrapping a narrow rectangular cover layer and wrapping it along the circular structure of the tire. The packaging design method uses polyester film as the main base material, which has good elastic tension. The surface of the product is coated with a moisture-proof engineering plastic surface, which can resist moisture and moisture. The film is smooth and soft, which can effectively prevent tire surface scratches. However, this approach also has some drawbacks. Since the packaging structure is cyclic winding, repeated packaging, and overlapping packaging strips, material consumption and packaging costs are relatively high. Moreover, the packaging is inconvenient, and it is inconvenient to improve work efficiency. It also takes a certain amount of time to remove the packing tape. Moreover, the damaged packaging tape is inconvenient to recycle, causing white pollution; however, the wrapping effect of the packaging tape is not ideal, and the tires are easily damaged during transportation. In order to improve the performance of the product packaging layer, we can choose to use plastic film, aluminum foil for composite material film, polyester film, etc. through the base tape, add strip-shaped tape, or can be stacked into a tape roll. The film can be made of ordinary pressure sensitive adhesive or double-sided film. It is adhered to the inner edge of the base tape. It can be adhered to the edge by one side, or it can be divided into two urban edges. When applied, wrap the packaging tape, and continuously press the film on the outside of the base tape of the packaging tape wound on the tire to form a continuous overall package. The sealing effect is good, it is not easy to leak water and dust, which prevents the pollution of the tires from the outside of the enterprise, and also overcomes the shortcomings of the current green packaging belts that are easy to dislocate and expose the tires.

How to identify the retreading of solid tire manufacturers?

The characteristics of forklift solid tires are good wear resistance, 3-4 times the service life of ordinary pneumatic tires, and no tire breakage (unless tire quality problems). Solid tires for forklifts are durable and pressure-resistant. Pneumatic tires will puncture, and the deformation will be relatively large when the load is loaded. You lift a pallet of goods and prepare to put them on the shelf. At this time, the tire punctures or the tire is deformed, and the goods will fall to death. Today Zhejiang Kunrong Rubber Technology Co., Ltd. What I share with you is how to identify the retreading of forklift tires, and learn quickly! The method of identifying retreaded tires is very simple: it is more common to observe the color and luster of the tires. The color and luster of the retreaded tires are relatively dim, so do not blindly buy such tires. The correct method is to identify the tires by the signs on the tires. There are some raised signs on the car tires, indicating the type and performance of the tires. These are the breakthrough points for identifying retreaded tires. The signs of retreaded tires are re-applied after retreading, while these signs of brand-new tires are integrated with the tire. The identification method is to scratch these signs with fingernails. Generally, these signs of retreaded tires are not very tight. , the one that can be caught must be the retreaded tire. Check whether the repairing process of the tire is fine. If there are bright slag, floating rubber threads and scorch, it means that the tire has been retreaded.

What is the impact of the performance of solid tires on the performance of the vehicle?

Influence of Solid Tire Performance on Vehicle Performance (1), the impact on the power performance of the forklift The entire cross-section of the solid tire plant is composed of rubber and cord fabrics of different formulations, and its internal friction must exceed that of pneumatic tires. Because the quality of life of solid tire companies is higher than that of pneumatic tires of the same specification, the social resistance and ramp resistance of their development acceleration are also larger. (2), the impact on the performance of the braking system The braking force of the forklift mainly depends on the braking system torque provided by the brake work and the adhesion of the road surface. Sufficient braking force can be obtained only when the forklift has sufficient braking torque and the ground can provide sufficient adhesion. Solid tires may have poorer adhesion system performance than pneumatic tires of the same specification. Therefore, the braking force of a solid tire is less than that of a pneumatic tire of the same specification. At the same time, solid tires have a greater impact on the product quality of pneumatic tires of the same specification. Therefore, under the same initial braking speed, the braking deceleration of Chinese tire forklifts is relatively small, and the braking system distance is relatively large. Therefore, in the case of the same specification, the braking system of a solid tire forklift will be poor. (3), the impact on the passability of the forklift For tires of the same specification, since the shape and size of the pneumatic tire is larger than that of the solid tire, the clearance between the forklift and the ground can be increased, so the passing performance of the pneumatic tire forklift is better.

What is the emergency treatment for the damaged solid rubber tire?

At present, solid rubber tires are generally only used in high-load vehicles and machinery running at low speeds, and are also used in fixed-position machinery compared with pneumatic tires, because solid rubber tires are more wear-resistant. How to deal with the damaged solid tire of forklift truck? Let's popularize it with Zhejiang Kunrong Rubber Technology Co., Ltd. below! 1. When the inner tube is found to have small holes, it can be hot or cold. File the roughness around the damage of the inner tube, stick the fire repair glue on the damage, and make the hole just in the middle of the repair glue, then install the tire repair clip against the normalizing glue, tighten the screw and then ignite The heating agent on the fire repair glue can be tightly bonded after 10-15 minutes. 2. When the outer tire of the solid rubber tire has cracks, holes, blistering, delamination and other damages, it should be repaired or renovated according to the specific conditions. When there are successive cracks around the tire carcass, the tread rubber has been polished and there are large holes, the carcass line layer has annular ruptures and the whole circle is separated, it should be replaced in time. 3. To be replaced in time: If the inner tube has problems such as folding, serious rupture, aging, stickiness, deformation, etc. that cannot be corrected, it needs to be replaced in time. Develop to check the tire pressure regularly, as far as possible, check it every other month. If the tire pressure is not enough, you should make up for it in time. Everyone should also check regularly before going on the highway to ensure the safety of driving.

Do you know the correct way to replace solid tires?

Replacing solid tires is a common problem encountered by many drivers and repairers. It is not an easy job, and it is necessary to understand the corresponding methods and skills. Let's take a look at it together. 1. First use a hydraulic jack to jack up the body structure Use a wrench to loosen the screws before jacking up the body, as it won't work if the wheel is in the air. The hydraulic control jack should be placed on a flat ground, and it should be avoided that there is no fulcrum and instability. Just jack up the car until the tires are off the ground. 2. Then turn the screw Before turning the screw, place the spare tire on the bottom of the car, so that we can effectively avoid the hydraulic control jack in the process of screwing the design. In the process of screw design, the wrench and the ground are at a 45-degree angle, which can better control the force. 3, followed by unloading the tire. In the process of unloading the tire, if the Chinese tire is too stuck, you can alternately kick the left, right and lower parts of the tire with your feet to make the tire loose. When you move the tires with your hands, cover your hands with gloves or a cloth as much as possible. Stains and oil on tires are no ordinary dust. It's hard to find a place to wash your hands after changing tires at a loss (movie). 4. Finally install the tires. The weight of solid tires and wheels is still very heavy. If we want to install Chinese tires at one time, can it be easy? You can cover the tire first, and then align the screw holes. When screwing a screw, you must strictly follow the principle of students' diagonal screwing. After screwing a production screw, screw the screw at the opposite corner. Do not screw clockwise or counterclockwise one by one.

What measures should be taken after the solid tire is worn out?

Compared with pneumatic tires, solid tires have higher wear resistance and stability. This performance is used for industrial vehicles such as low-speed and heavy-load hoisting vehicles, tractor vehicles, and flat scooters. As an important part of engineering vehicles, tires are used correctly or not, which directly affects the performance of various performances and the length of service life of the vehicle. What should be done if damage occurs? Damage treatment of solid tires: 1. When the tire has cracks, holes, blistering, delamination and other damages, it should be repaired or renovated according to the specific situation. When there are successive cracks around the tire carcass, the tread rubber has been polished and there are large holes, the carcass line layer has an annular rupture and the whole circle is separated, it should be replaced. 2. When the inner tube is found to have small holes, it can be hot or cold. File the roughness around the damage of the inner tube, stick the fire repair glue on the damage, and make the hole just in the middle of the repair glue, then install the tire repair clip against the normalizing glue, tighten the screw and then ignite The heating agent on the fire repair glue can be tightly bonded after 10-15 minutes. 3. Timely replacement: If the inner tube has problems such as folding, serious rupture, aging, stickiness, deformation, etc. that cannot be corrected, it needs to be replaced in time. Develop together to check the tire pressure regularly, try to check it every other month, if the tire pressure is not enough, it should be made up in time. Routine inspections are also required before boarding the expressway to ensure driving safety. In the process of daily use of solid tires, because many car owners ignore the condition of tires, it is easy to cause accidents. As long as you pay attention to inspection and maintenance, and develop good driving habits, you can travel the world with peace of mind.

Solid tires, new tires have longer braking distance than old tires?

Solid tires are one of the more important parts of a car and a safety barrier. Only a person who correctly understands various professional knowledge of tires can match our own car with tires suitable for students' own models. Today, Zhejiang Kunrong Rubber Technology Co., Ltd. will give you a detailed introduction to some knowledge of tires. Tires are one of the most important parts and technologies in automobiles, and they are also a barrier to national security. Understanding "12.00-20 20PR" means that there is no difference, so that you can choose the correct size of "shoes" for your car, but this It is far from enough. Whether the tire company is suitable for the car and whether it meets the market demand depends on the key performance indicators such as "wear resistance index" and "wet adhesion". We can ignore too much boring data, and the main analysis Explain some common but easily overlooked tire development problems. Do new tires actually brake longer than old tires? This social problem seems very illogical to us. The tread pattern of old tires has almost worn down to an important indicator line in China. How can we develop new tires with deeper tread patterns and shorter braking distances? Some tire testing agencies conduct specialized studies. Let’s talk about the conclusion first, we have no direct relationship between the tread depth and the braking distance. Older tires perform better on braking distances because their nearly smooth tread allows them to make more contact with the ground, creating more traction. Of course, the new tire company has a deeper tread, drainage and naturally better than the old tire, and the handling behavior on wet roads and rain will be better.
