When assessing the price of a baggage trailer, you must look beyond the initial cost and evaluate load capacity (typically 1,500kg to 3,000kg), chassis material (hot-dip galvanized steel is preferred for corrosion resistance), and braking systems (parking brakes and overrun brakes). High-quality trailers feature heavy-duty solid rubber tires and reinforced tow bars to withstand the rigors of airport ground support operations. A lower price often indicates thinner steel or inferior welding, which leads to higher long-term maintenance costs.
