Common faults and maintenance methods of trolley boxes

Usage and Maintenance Methods for Trolley Boxes
1. Poor extension and retraction of the pull rod
When the pull rod cannot be smoothly extended or retracted, do not use brute force to pull or retract it. Forceful force can easily cause the pull rod to get stuck. When the pull rod in the trolley box gets stuck, most users will continue to use brute force, which will only cause the pull rod to get stuck more and more, causing it to become unusable and delaying travel. The correct method should be to add engine oil or vegetable oil to the joint of the pull rod. After lubrication, this problem is basically easy to solve.
2. Pulley stuck, loose, and detached
If there is a noticeable discomfort with the pulleys when dragging the trolley box, lubricating oil should also be applied to the bearings of the wheels at this time. When there is a possibility of looseness or detachment of the wheel, please do not continue to use the damaged wheel for towing, use the other wheel instead, or walk directly with the suitcase. If conditions permit, use corresponding tools to tighten the screws and screws of the wheels. If the screws come off and cannot be found, it is easy to find what you need by checking if there are any people or storefronts engaged in luggage maintenance near the site.
3. Damaged box
If it is a hard box and the damage is only a small crack and not serious, you can use some universal adhesive, AB adhesive, etc. on the market to repair it yourself. The rupture of the soft box needs to be repaired at a repair location. It needs to be weighed that the brand box, after being self selected for repair, may no longer be eligible for warranty.
4. Zipper cracking
Place luggage according to the capacity of the box, and do not exceed the carrying capacity of the box too much. The bumps during transportation or check-in can easily cause the zipper of overloaded bags to break open. If these things happen, you can use a buckle to temporarily deal with them. Take a few buckles with you when you go out, just in case.
