Abstract

Wheelchair undercarriage attachments (10) of the present invention can include a ramp assembly (20) having at least one ramp (22) for allowing entrance of a wheelchair (12) and support thereof during use. A pair of continuous tracks (42) can be oriented in a substantially parallel relationship and operatively connected to the ramp assembly (20). A drive mechanism (70) can be operatively connected to the pair of tracks (42). The drive mechanism (70) can include a hand crank (92) oriented in an accessible position during use and configured to transfer forces to the pair of tracks (42) to cause motion. Such devices can allow for improved mobility of an attached wheelchair over a variety of terrains such as snow, sand, mud, etc.
