Stair Case Trolley for Goods Transportation

Today, simple mechanical devices such as one-wheel and two-wheel wheelbarrows are used in a variety of industries, not just for domestic purposes. However, their use is limited to the transportation of goods from one location across the floor to another. None of the formalized structures available on the market meet the need for support when climbing stairs with luggage. To overcome this difficulty, stair wheels (a combination of three wheels) are used instead, reducing the effort required to lift. This paper designs and manufactures a three-wheeled stair climbing trolley for transporting significant loads across rough surfaces and up stairs using an improved wheel assembly with relatively little manpower and manufacturing costs. Focuses on. Describes design concerns such as the steep slopes of stairs and the stability and speed of trolleys when climbing stairs. Hybrid vehicles such as B. Tricycles can be used to transport multiple items in different locations where mechanical elevators cannot be installed.
