There are a few benefits to using an arched loading ramp over a traditional flat one. First, the arch provides more clearance for taller vehicles. This is especially important if you're frequently loading cars or trucks that are higher off the ground. Second, the curve of the ramp helps distribute weight more evenly, which can be helpful if you're carrying heavy loads. Finally, the arched shape can make it easier to line up your vehicle with the ramp, making for a smoother transition when loading and unloading.
