Abstract: A momentum arresting ramp that includes a plurality of steps that each includes a slider receiving surface and a transition surface. The steps may enable a device with wheels to be moved down the ramp by a user, without inconvenient gravity building momentum of the device down the ramp. For example, the steps may be spaced apart along a first axis such that a first slider of the device is never in contact with one of the transition surfaces when a second slider of the device is in contact with another one of the transition surfaces. The configuration of the steps and the sliders may enable the device (e.g., a device heavy enough to typically require two users to unload using a planar ramp) to be easily and conveniently unloaded by a single user.
