From a technical point of view, the design of the curb stone clip trolley fully considers mechanical principles and ergonomics. The frame is made of high-strength steel to ensure sufficient load-bearing capacity and stability. The casters are usually made of wear-resistant and impact-resistant materials, such as polyurethane. This material not only has good wear resistance, but also provides a smooth moving experience on various floors. The special clamp device can be adjusted according to the size of the curb stone to ensure firm clamping and prevent slipping during transportation.
