The motorized stair climbing wheelchair was invented in 2018 to transport disabled patients up and downstairs. Only one person is needed to operate this wheelchair. The loading capacity of the power evacuation chair is 180kg; after being full of electricity, the stair wheelchair can climb up 100 stairs with 80KG person. We produce this kind of electric climbing wheelchair, whose purpose is to supply assistance for those who need to climb stairs up and down. Meanwhile, it also can be used as a motorized wheelchair on the ground.
