Trolley case airplane wheels:
Trolley case universal wheels: Trolley case universal wheels are also called universal wheels. In fact, universal wheels are wheels that can rotate 360 ??degrees. Regardless of whether the wheels are single-row wheels or double-row wheels, as long as they have 4 wheels, they can be called universal wheels, so airplane wheels are also universal wheels!
Trolley box one-way wheels: Some people call the trolley box one-way wheels directional wheels. This type has only two wheels and cannot only rotate 360 ??degrees, but can only go straight!
Trolley box silent wheel: The name of the trolley box silent wheel is mainly due to the material of this wheel. When the box is pulled on the ground, the sound is very light and almost silent, so it is called silent wheel!
The following figure shows the difference between trolley box universal wheels, aircraft wheels and one-way wheels:
Price comparison between aircraft wheels, universal wheels and one-way wheels
: Under normal circumstances, aircraft wheels use silent rubber wheels, so they are basically silent. The size of aircraft wheels does not change much. They are basically larger than universal wheels, but smaller than one-way wheels; universal wheels The wheels are made of various materials, including silent rubber wheels. Aircraft wheels with the same specifications use more materials than universal wheels. Because an aircraft wheel uses two sides of material, generally aircraft wheels are more expensive than universal wheels. Overall Aircraft wheel trolley cases are also more expensive than universal wheel trolley cases. Universal wheels use 4 wheels, while one-way wheels only use two, so one-way wheels are the cheapest.
The difference between universal wheels, airplane wheels and silent wheels: The main difference between universal wheels and airplane wheels is the shape, while the difference between universal wheels and silent wheels is the material. Generally speaking, as long as there are 4 wheels , no matter what material the wheel is made of, it can be called a universal wheel. As long as it has 4 wheels and 8 sides, it can be called an airplane wheel regardless of the material. So the airplane wheel must be a universal wheel, and the universal wheel is not the same as an airplane wheel. As long as the wheels are made of rubber, whether they are airplane wheels, universal wheels, or one-way wheels, they can be called silent wheels, because the wheels made of rubber make very little sound when they come into contact with the ground, but they are not silent.
Aircraft wheels, universal wheels and one-way wheels are suitable for road conditions: aircraft wheels and universal wheels are more suitable for stable intersections, such as airports, where the ground is smooth and smooth, and the trolley case with universal wheels can be pushed It is pullable and very convenient; if you are on a bumpy mountain road or dirt road, choose a one-way wheel. The wheels of a one-way wheel are generally larger and easier to pull. Moreover, a one-way wheel has the advantage of being better than a universal wheel. Durable. For example, generally the wheels that are damaged when checked on an airplane are universal wheels, because all four wheels of the universal wheels are leaking, and part of the one-way wheels is leaking.
So when transporting trolley cases by air, only The directional wheel is more durable than the airplane wheel, and the airplane wheel is more durable than the universal wheel! Introduction to the material selection of aircraft wheels, universal wheels, and one-way wheels:
1. Select wheel material: first consider the size of the road surface, obstacles, and residual substances on the use site (such as iron filings, grease), The appropriate wheel material is determined by different conditions such as the environmental conditions (such as high temperature, normal temperature or low temperature) and the weight that the wheel can carry. For example: rubber wheels are not resistant to acids, grease and chemicals, while super polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels and high-temperature-resistant wheels are suitable for different special environments.
2. Calculate the load-bearing weight: In order to be able to calculate the required load-carrying capacity of various casters, it is necessary to know the dead weight of the transportation equipment, the maximum load and the number of single wheels and casters used. When calculating the load of a single caster, a certain insurance factor must be given. When the ground is relatively flat, the load of a single caster = (total weight of equipment? number of casters installed)? 1.2 (insurance factor); if the ground is uneven, the calculation is: single caster Caster load = total weight of equipment? 3, because no matter what kind of uneven ground, there are always at least three wheels supporting the equipment at the same time. This algorithm increases the insurance factor, is more reliable, and prevents insufficient load-bearing, which greatly reduces the life of the casters or causes ACCIDENT.
3. Determine the wheel diameter: Generally, the larger the wheel diameter, the easier it is to push, the greater the load capacity, and the better it can protect the ground from damage. When choosing the wheel diameter, you should first consider the weight and load. It is determined by the starting thrust of the truck under load.
4. Choice of soft and hard wheel materials: Usually the wheels include nylon wheels, super polyurethane wheels, high-strength polyurethane wheels, high-strength artificial rubber wheels, iron wheels, and pump wheels.
Super polyurethane wheels and high-strength polyurethane wheels can meet your transportation requirements whether they drive on indoor or outdoor surfaces; high-strength artificial rubber wheels can be used in hotels, medical equipment, floors, wooden floors, tile floors, etc. It is required to drive on the ground with low noise when walking; nylon wheels and iron wheels are suitable for places with uneven ground or iron filings and other substances on the ground; while pump wheels are suitable for places with light loads and uneven roads
< p>Comprehensive comparison of aircraft wheels, universal wheels, and one-way wheels (personal opinions are for reference only): Each wheel has market demand. At present, no wheel has completely replaced which wheel. Please choose the one that suits you. If there is one, With the extra money, you can buy boxes with different wheels to try out and prepare for buying boxes in the future. Under normal use, the lifespan of a hard-shell trolley case is about 5 years, and that of a soft trolley case is about 10 years!The most easily damaged parts of a trolley case are the trolley bars and wheels
You need to pay special attention to these two places when purchasing;
1. According to the price ratio, from From high to low, they are aircraft wheels, universal wheels, and unidirectional wheels;
2. According to durability ratio, from high to low, they are unidirectional wheels, aircraft wheels, and universal wheels; 3. According to cost-effectiveness, from high to low The lowest order is the universal wheel and the unidirectional wheel;
