The Model 8.0 four-wheel trolley is much more stable and less prone to tip over than previous three wheel models. Thanks to its patented folding mechanism 4XFOLD, it has a compact folded size, making the cart easier to transport and store when not in use. The construction is very sturdy and durable and scores with functional features such as the dual front brake system and individually adjustable front wheels, which guarantee the precise and straight running of the cart.
