The EZ Rizer Lift and the Liberty Lift are both platform-type seat lifts that elevate one from the level of his wheelchair to the level of the pickup truck or all-terrain vehicle seat. The lift platform, which can be installed on either side of the vehicle, facilitates easy transfer. Once the person is off the lift seat, it is folded up against the side of the vehicle seat. Both lifts are electrically powered from the vehicle's 12-volt battery and have a 300-pound rated load capacity. The lift platform is raised up and down by a ball screw, so there is no danger of free-fall should the system fail.
