Design and Fabrication of 3 in 1 Foldable Hand Trolley

The project "Design and fabrication of 3 in 1 foldable trolley" that has been proposed is from facing difficulties when trying to move a lot of heavy items while using a regular trolley. Older people who use a regular trolley to move heavy items can experience backache. This 3 in 1 foldable trolley project's target is to facilitate and save energy for users. This project intends to design and fabricate a 3 in 1 foldable hand trolley to consume less energy, especially for workers or people who need to lift a lot of heavy items daily and have 3 styles to lift items. To make this project, the most suitable and affordable material is by using steel as the main material. Other than that, such as rubber tires and non-slip fabric for the handle. There is also an idea about putting a pedometer to record the distance when using the trolley, and even how much our calories burned. The objectives of this project are to upgrade a regular trolley to a trolley that can make lifting heavy items easier and more comfortable
