A mobile boarding bridge, also known as a mobile loading dock, is a device that creates a temporary passage between the truck and the ground. It is made of high-strength materials and has a robust structure that can withstand the pressure of heavy loads. The design of the mobile boarding bridge allows goods to be easily transported from the ground to the truck, or unloaded from the truck to the ground, which greatly improves the efficiency of logistics and transportation.

A dock leveler, also referred to as a dock ramp or loading dock leveler, is a mechanical device utilized to bridge the gap between a loading dock and a truck or trailer. Its primary objective is to facilitate the safe and efficient loading and unloading of goods or materials. Dock levelers ensure a seamless transition between the dock and the truck bed, enabling smooth movement of forklifts and other material handling equipment.
