The SC500-AF scooter/mobility carrier is an affordable way to transport a power chair, wheelchair, or scooter by using a vehicle hitch receiver! An integrated 59-1/4" long loading ramp guides a powerchair or scooter up to 28-1/4" wide into the carrier and then folds up vertically for transport. When the carrier is not loaded, the loading ramp can be folded flat for rear hatch or tailgate access or can be folded vertical for extra clearance for parking spaces or garages. The loading ramp is locked vertically by two spring pull pins and features two anti-rattle springs to reduce ramp vibrations during travel. The SC500-AF scooter transport carrier also includes an Anti-Tilt bracket and Pinch bolt (use one or the other) to reduce carrier wobble and a 5/8" hitch pin.
Scooters or power wheelchairs weighing up to 500 lbs are secured to (4) 1"D eyelet tie-down points located near each corner of the 46-1/2" x 30-1/4" (usable size) platform. These eyelets are designed for use hook-end tie-down straps and use with the strongest part of the carrier frame for support. It's recommended to use these tie-down points instead of securing straps to the platform rails which may cause the straps to slide or become loose during transport. Be sure to properly secure a power scooter using hook-end tie-downs with the transport carrier eyelets.
Raised-edge 4" wide rungs are spaced 1" apart along the loading ramp and scooter carrier platform. Ramp rungs are designed for high traction with power scooter or wheelchair tires during loading while the platform rungs help eliminate scooter or powerchair shifting from side to side while hauling behind a vehicle. Spaces between the rungs allow water and debris to pass through, reducing build-up on the scooter transport carrier surface.
The power wheelchair and scooter transport carrier platform, frame, rungs, and ramp are constructed from heavy duty aluminum while the underside support tube and brackets are made from heavy duty reinforced steel with a gray powder-coat finish. Some assembly is required and easy to follow instructions are included. Comes with a 1 year warranty!
