The design of the luggage trolley provides the reliability and durability you can count on. The 6-inch pneumatic tires and 5-inch swivel casters roll smoothly on any surface. [LARGER LOAD CAPACITY] Thanks to the high-strength aluminum alloy material, and the re-optimized design of the body, our hand trucks can carry more weight than other products in 4-wheel mode - 460lbs, and can also carry 330lbs in 2-wheel dolly. [EASY TO OPERATE & PORTABLE] The weight of the whole truck is only 19.8lbs, and the fully folded size is 28.7in x 14.7in x 8.7in, which can be easily put into the trunk of your car, providing great convenience for you to carry large or heavy items. You receive the product pre-assembled and unfolds in seconds from fully folded to a 2-wheel dolly and from a 2-wheel to 4-wheel cart in seconds.[WIDE APPLICATION] Convertible hand trucks can be used as upright or platform trucks to allow the truck to carry a wider range of items than other types of hand trucks. Also known as a multi-station handcart, it can be widely used in moving home, moving goods, warehouses, supermarkets and other scenarios.
