The magnesium alloy manual wheelchair is light because magnesium alloy has the characteristic of low density. The density of magnesium alloy is approximately 1.74g/cm³, which is much lower than that of common metal materials such as carbon steel (with a density of approximately 7.85g/cm³) and aluminum alloy (with a density of approximately 2.7g/cm³). While ensuring the structural strength of the wheelchair, it can effectively reduce the overall weight of the wheelchair, making it more convenient to carry and operate.
The design of the travel bag and the quick-release rear wheel offers numerous benefits for travel. The design of the travel bag allows the wheelchair to be folded and stored inside, making it convenient to carry and transport. It can effectively protect the wheelchair from damage such as collisions and scratches during the journey. At the same time, it is also convenient for taking public transportation such as planes, trains, and cars, without causing inconvenience due to the size of the wheelchair. The quick-release rear wheel design further enhances portability. After removing the rear wheels, the wheelchair becomes smaller in size and is easier to fit into the trunk of a vehicle or a suitcase. Moreover, during the trip, if the rear wheels of the wheelchair malfunction, the quick-release design makes it convenient to quickly replace the spare wheels without affecting the travel itinerary.
The service life of a magnesium alloy manual wheelchair is usually around 5 to 10 years, but the actual service life can be affected by various factors.
If the daily usage frequency is high, for instance, it is used for a long time every day, the components of the wheelchair will wear out relatively quickly, which may shorten its service life to 5 to 7 years. However, if the usage frequency is low, the number of times it is used each week is small, and the usage environment is good, without bad weather conditions or complex road conditions, and regular maintenance and upkeep can be carried out, such as regular inspection and replacement of vulnerable parts, cleaning and protection of the magnesium alloy frame, etc., then the service life of the wheelchair may be extended to 8-10 years, or even longer. In addition, the service life of magnesium alloy manual wheelchairs of different brands and qualities will also vary. Products from high-quality brands usually have better guarantees in terms of materials and craftsmanship, and their service life is relatively longer.
The following are the daily maintenance methods for magnesium alloy manual wheelchairs:
Cleaning
Regularly wipe the wheelchair with a clean and soft damp cloth to remove dust and stains on its surface. For stubborn stains, you can dilute a mild cleaner and wipe it, then rinse it clean with water and dry it.
Avoid using cleaners containing abrasives, strong acids or strong alkalis to prevent damage to the protective film on the surface of the magnesium alloy.
Inspect the components
Regularly inspect all components of the wheelchair, such as the wheels, brakes, armrests, and footrests, to ensure they are securely connected without any looseness, wear or damage.
Check the inflation of the wheels, maintain appropriate tire pressure, and repair or replace the inner tube in time if there is any air leakage.
Lubrication and maintenance
Regularly apply an appropriate amount of lubricating oil to the moving parts of the wheelchair, such as the rotating shafts, bearings, and braking devices, to keep them running smoothly and reduce wear and tear.
Be careful not to let the lubricating oil come into contact with the surface of the magnesium alloy to avoid affecting its appearance.
Store
Wheelchairs should be stored in a dry and well-ventilated place, avoiding damp environments to prevent the magnesium alloy from rusting.
When not in use for a long time, the wheelchair can be folded for storage to save space, but it should be placed stably to avoid deformation under pressure.
