目前中国仍有近一半的城市居民住在7层以下没有电梯的建筑,残疾人、老年人上下楼往往需要一个身强体壮的人背着,或者由4个人抬着轮椅才能下楼。这一现状给无数残疾和老年人带来生活的不便,而目前市场上兴起的电动爬楼梯轮椅又存在着诸多问题。 Currently, nearly half of urban residents in China still live in buildings with no elevator below the 7th floor. People with disabilities and the elderly often need to be supported by a strong man or a wheelchair can be taken down by 4 people. This situation has brought inconvenience to innumerable disabled people and the elderly. However, there are still many problems with the current electric climbing staircase wheelchair on the market.
