Getting a wheelchair up even a few steps can be a nightmare, and ramps are not always provided, especially overseas. Mabis’ latest version of its portable lightweight ramp system may save the day (and your back). Packed inside a nylon bag are two sturdy aluminum tracks with nonskid treads. Placed parallel to each other (the distance between the tracks depends on wheelchair width) the three-section tracks telescope from three to five feet, creating a ramp with a 660-pound (330 pounds per track) weight capacity. The ramps stash easily inside the bag, which attaches to the back of the wheelchair for transport. Weighs about 14 pounds. Getting the knack of the ramp system may take some practice, so experiment at home first.
