Trolley rod, roller how to choose
China Trolley Trading Network is your one-stop source for comprehensive, in-depth, and multi-angle information on trolley cases. Whether you're looking to buy, wholesale, or join as a manufacturer, we offer detailed insights into trolley case products and services. Here are three key factors to consider when purchasing a PC trolley case:
First, the rod structure plays a crucial role in the functionality of the case. The rod material is typically made from aluminum alloy or steel, and it can be designed with different configurations—single, double, or triple sections. Double and triple rods allow for adjustable length based on the weight and size of the contents. It’s essential to choose a built-in rod made of strong yet lightweight materials like aluminum, which ensures durability without adding unnecessary weight. Also, check the overall design—does the pull handle move smoothly? Are the buttons easy to use?
Next, the roller type significantly affects the ease of movement. Most trolley cases use rubber wheels that are wear-resistant, shock-absorbent, and quiet. There are two main types: built-in and external. External rollers, often called "caster wheels," allow 360-degree movement, making it easier to maneuver through tight spaces. However, they may not be as durable under heavy loads. Built-in rollers, while less flexible in direction, tend to be more reliable and safer during loading and unloading.
Last but not least, the zipper is another important feature. A smooth and sturdy zipper is essential for security and convenience. While smaller zippers might be sufficient for light use, larger zippers usually offer a more secure and satisfying closing experience. Make sure the zipper doesn’t stick or jam, especially when the case is fully packed.
