I bought this cart because I needed a ramp that wasn't too heavy for me when I have back problems. To me, this is the perfect ramp for a portable handrail belt (trolley) to bring 5 gallon water bottles inside. The entrance is an 8 inch step and this ramp is not too steep for this height. The ramp rests on a thick rubber outer mat that makes it stable. The sill at my door is uneven so I don't step on the ramp itself, I have enough room in the door to walk to the ramp and into the house while driving the cart up the ramp. Most ramps weigh between 25 and 30 pounds and I can't lift that much weight if my back is off balance.
