With our foldable stair transport trolley, you can decrease physical labor and carry your luggage with ease! Our portable climbing cart combines three-wheel chassis with a folding hand cart, making it stable and easy to move. This stair climber cart is constructed from aluminum, which is rust-resistant, lightweight yet can carry up to 154.3 lb. It comes with three wheels on each side. There are always two wheels in contact with the ground to improve balance and stability. The handle height can be adjusted from 24.8" to 33.1", and also the highest up to 39.4", making it very convenient and practical. When not in use, this transport cart can be folded flat with a modular folding chassis.
