Handicap van conversions with power wheelchair ramps and doors are the most popular because of their ease and convenience. However, manual conversions are also popular because they cost less both to purchase and to maintain. Power conversions also typically have a kneeling feature that reduces the angle or steepness of the wheelchair ramp. By compressing the suspension, the floor of the van lowers on the ramp side. We find that for most wheelchair users—especially those in manual wheelchairs—this angle reduction is very helpful, if not critical.
