The body is made of aluminum alloy material, which is lightweight and simple. A basket is equipped in front of the handle of the trolley for placing valuable items or small objects carried with you. The design of the trolley chassis with a higher front and a lower rear can prevent luggage from sliding when going down an elevator or a slope. The chassis surface is equipped with rubber strips for anti-slip and noise reduction. Pressing down the handrail releases the brake. When the handrail is released, the trolley is automatically braked. You can let go at will and park without worrying about sliding. There are also anti-collision strips equipped under the body. The natural rubber casters are shock-absorbing, wear-resistant and silent. They can be stacked and placed to save storage space.
