The trolley can be handheld or dragged, the wheels of the trolley we usually use are basically located at the bottom of the box, and modern people have designed a new form of trolley, the box is designed into the shape of a cylinder, the wheels are outsourced to the outside of the box, such a roller design makes this trolley can be better adapted to different terrain, such as directly pulling the box can easily go up and down the stairs. 2012 The main materials used are cloth cases, ABS hard cases, leather cases and PC, and the usability is divided into three main categories: directional wheels, universal wheels and the latest removable universal wheel trolley cases.
Material of the trolley case
ABS is a relatively new material, is also more popular fashion material, the main feature is lighter compared to other materials, the surface is more flexible, rigid, impact resistance better protection of the items inside, although touching the soft feeling is not strong, but in fact is very flexible, the average adult standing on it are no problem, cleaning is more convenient, the disadvantage is easy to have scratches, but on a case cover will be good The disadvantage is that it is easy to get scratches, but with a case cover it will be better.
Oxford cloth is similar to a kind of nylon, the advantage is wear-resistant, practical, the disadvantage is a thousand and one, in the airport is not good to distinguish the luggage, and relatively heavy, but consignment or something completely do not have to worry about will bring harm to the box, with a few years or the same, ABS's with the increase in time, the surface of the wear and tear, may use a few times to show a long time.
PU leather, as the name suggests, is artificial leather pu material, the advantages of this kind of box is very similar to the cowhide, appears high-grade, and not like the leather box as afraid of water, the disadvantage is not wear-resistant, not very strong, but the price is low.
Canvas: This fabric box is not very common, but canvas, the biggest advantage of the same as Oxford cloth is wear-resistant, and the disadvantage is that the impact resistance is not as good as Oxford cloth, canvas material on the colour is very uniform, there may be a brighter surface. With the accumulation of time, there is an old and unique sense of vicissitudes.
PVC is also known as a hard case, as if it were tough, drop resistant, waterproof, impact resistant, wear resistant, stylish and arguably much, much stronger than ABS, the strongest of the cases, with a smooth, good looking surface without the worry of scratches due to brutal handling. Because it will not be very obvious. The biggest disadvantage is heavy, moving about 20 pounds, you know that many airlines limit in 20 kg, which means that the box weight accounts for half.
Cowhide is generally the most expensive, and there is no cost-effectiveness. It is afraid of water, grinding, pressure, and scratching. Although as long as it is properly kept, the box is very valuable. But using leather is not environmentally friendly, remember that there is no harm if there is no sale.
In general, it depends on what you do with it, if you travel or get married, it is suitable to use ABS, good-looking, and good to distinguish the luggage, because the weight is light can also be loaded with more things. If you are moving, it is suitable for Oxford cloth or PC (PVC), which is resistant to falls and wear. If you are going abroad or to school, you can use ABS, which can be used for a simple wardrobe. It is practical to put things in. In addition to the exterior of the box, there are also 2 wheels and 4 wheels (universal wheel). 4 wheels can be pulled and pushed flat, which is more suitable for gentle ground and saves energy. 2 wheels are suitable for general road surface, and the wheel life is longer than 4 wheels.
