Selecting strong and long-lasting telescopic luggage handles is especially crucial. ما عليك سوى أن تتخيل أنك تحمل حقيبة تزن ثلاثين كيلوغرامًا عبر مطار مزدحم بينما يهتز المقبض, ruining your trip. It’s a challenging experience.
According to surveys, trolley handle failures account for 32% of luggage returns, which increases expenses for many manufacturers. This demonstrates the significance of a quality luggage handle. It contributes significantly to the luggage’s stellar reputation for quality in addition to lowering the failure and return rates.
As luggage manufacturers and consumers, how should we choose telescopic luggage handles that meet the needs of use and are strong and durable?
First, let’s understand how the handle works.
Lever mechanics system: The principle of the handle of a telescopic suitcase is based on an internal retractable structure, usually containing a tube and an internal piston. The user presses the button or wrench to unlock the mechanism, then freely pulls out the handle. To store it, they push the rod back until the same mechanism locks it securely in place.
Through this structure, the pull rod can be extended and retracted as needed, which is convenient for users to use in different scenarios.
Let’s first examine the handle’s operation. Lever mechanics system: A telescopic suitcase’s handle operates on the basis of an internal retractable structure, typically comprising an internal piston and tube. You can unlock the structure by pressing a button or wrench. This action allows you to pull out the handle freely. When you push the rod back, the same mechanism locks it inside the box for compact storage.
Users can conveniently use this structure in a variety of situations because it allows the pull rod to be extended and retracted as needed.
Criteria for Selecting Superior Telescopic Baggage Handles:
I. Selection of Core Materials
1. Preferably, aluminum alloy or aviation aluminum
Pull rods made of aluminum alloy are lightweight and resistant to corrosion, و 6063 aluminum tubes exhibit good processing performance, weldability, مقاومة التآكل, and plasticity. The compressive strength ranges from 160 ل 200 MPa.
Iron luggage handles should be avoided because they are heavy, prone to rust, and not very durable.
2. Take note of the tube wall’s thickness.
High-end pull rods feature aluminum tube walls measuring 1.2 ل 1.5 mm thick, while regular suitcases use tubes under 1 mm thick that deform under weight or impact.
II. Structural design points
1. The multi-level adjustment function
Choose a pull rod with three to four levels of height adjustment (ideal for 150-190 cm). To prevent arm fatigue while pushing, it can be changed based on terrain and height.
For example, brands like Samsonite and 90 Points did well in the test.
2. Reasonable telescopic gap.
When a high-quality pull rod is entirely pulled out, it should wobble somewhat. This is to avoid thermal expansion and contraction or jamming while under force, not a quality flaw. However, please pay attention to the reasonable gap. If the gap is excessively great, the product is unqualified, resulting in excessive swing and increased suitcase movement.
3. The double-pole balance design
The wide-distance double-pole arrangement (spacing > 30 cm) disperses force and reduces the possibility of rollover. For example, Diplomat and Goldlion draw rods did not break during the oscillation impact test.
III. Measured Performance Verification.
1. Luggage handle strength test.
High-quality pull rods must pass at least 3,000 pull-and-close fatigue tests, have a load-bearing strength of > 1500 N (approximately 150 kg tension), and have a deformation of < 3 مم, as per industry standard QB/T 2155-2018.
For example, AMERICAN TOURISTER and NetEase Yanxuan fared admirably in the test.
2. Torque resistance, anti-jamming
Trolleys that have passed both the step and walking performance tests are more reliable. For example, Samsonite and LEVEL8 tie rods continue to function after simulating 45 kilometers of drag on the airport road.
IV. Brand and Model Recommendations.
1. Select prominent telescopic baggage handles from well-known companies. These proven products offer greater durability, making them the top choice for most users.
2. When choosing telescoping handles for baggage with an innovative design, you should pay close attention to the inquiry and testing procedure, as well as carefully examine any relevant test findings.
3. If you need to personalize a suitcase handle, you should verify whether the manufacturer has independent R&D capabilities, such as mold creation, design capabilities, and its own production line, as well as the timeliness of delivery.
Appendix: Quick Self-Test Method for Trolley Handle Durability.
1. Press test: The handle button should have a stable pressing force of 5-8 N. Avoid excessive tightness (>10 N) or looseness (<3 N).
2. Shake test: After fully pulling out the trolley handle, the left-right swing should be less than 15 mm and the front-back swing should be less than 25 مم; otherwise, structural looseness may occur.
3. Brand certification: Products that have received TUV certification (32 kg load-bearing dynamic test) or ISO 9001 process certification are preferable.
Trolley suitcases that meet the aforementioned specifications can withstand high-intensity use for over ten years.
