The difference between the suitcase universal wheel and the airplane wheel:
The universal wheels are actually movable casters, which are wheels that can rotate 360 degrees horizontally, while the aircraft wheels are fixed and cannot be rotated.
The aircraft wheels are mainly made of silent rubber wheels, so the sound of the aircraft wheels is particularly small when in use. The different materials used for universal wheels result in higher noise than aircraft wheels.
The stability of the aircraft wheels is very good, and the universal wheels are too flexible which leads to poor stability.
The universal wheel is suitable for relatively stable intersections. If the road is very stable, the wheels of the universal wheel will be very flexible, and it will feel very labor-saving when pulled up; but if it is on a rough road, the universal wheel will appear somewhat It's hard work. At this time, you need to use airplane wheels. These wheels are usually a bit larger, so they can be pulled easily.
Precautions for the use of suitcases:
1. Trolley cannot be used as a handle: The cushioning function of the suitcase handle can prevent the weight of the suitcase from damaging the tie rod, and it can also prevent the weight of the suitcase from causing accidental sprains to the human body when lifting the suitcase. Lift the box directly with the lever, instead of using the handle.
2. Heavy fall, heavy pressure: If the bag is stressed and exceeds the pressure it can withstand, it will still cause damage. The hard box will protect the contents of the box better than the soft box. The soft box can use more space and have different purposes. The right box is very important.
3. Damage to the wheels: The wheel material of the suitcase is wear-resistant and slippery (smooth towing). Please lift the suitcase when going up and down the stairs or crossing the ditch. Don't pull the suitcase directly. When the wheel falls to the ground, it causes a great impact, causing injury to the wheel.
