Design of carry cart using on the stairs for delivery person

Abstract

I propose a carry cart using on the stairs for delivery person. Due to the rapid growth of the home delivery market, redelivery becomes a serious problem. As a solving measure, a new delivery method that female employees delivery packages as a part-time job is done in residential area. Home delivery companies want to increase the number of female employees however the transportation of heavy loads in stair climbing is a big problem. The aim of this proposal is to support the transport of heavy luggage in stair climbing and anyone will be able to carry heavy luggage at the delivery site.
