The goal of this project is to make it simple to transport the cylinders up and down the stairs. When doing work, a good tool is essential. However, there was an issue when you wanted to deliver the gas cylinder upstairs to a customer's house. So we devised a method for easily raising the cylinder. We've added a trolley to make it easier to get upstairs. Furthermore, it reduces human effort. This trolley is designed for workers who deliver gas cylinders to customers' homes. This system is usable daily. The design is based on a bearing capable of carrying a single cylinder at the speed of a normal human. A trolley is a small vehicle with wheels that can be moved around and is used to transport cylinders. A cylinder trolley is a type of trolley with rotating wheels that can be moved up and down the staircase. This can significantly reduce back injuries. This study may lead to the development of a new method for transporting heavy cylinders up and down stairs. A trolley is a piece of equipment used to transport heavy objects from one location to another. A trolley aids in reducing the amount of effort required to lift the cylinder up the stairs. Several other designs have been proposed for this project, but we want better stress distribution so that we can travel over uneven surfaces, such as stairs. The trolley in this proposed design is outfitted with a set of Tri-Lobe wheels, which are the most important part of the climbing mechanism that allows the trolley to move along uneven surfaces.
