A handcart is a transport vehicle pushed and pulled by human power; it is the ancestor of all vehicles. Although handcart material handling technology has continuously developed, handcarts remain an indispensable tool for transportation.
1. My handcart's frame is usually quite small, making it inconvenient and unstable when carrying large items. The frame could be improved to allow for extension and retraction.
2. To make pushing the cart easier and less strenuous, the frame could be folded up at a certain angle.
3. Pushing a cart downhill is a very troublesome task; it's easy to tip over. This is especially true in crowded train stations. Anyone who has used a handcart can relate. Adding a braking device would reduce the stress when going downhill.
