This paper is a research report on a platform trolley with six different tasks that were solved.
The Platform Trolley is equipment used to move heavy loads from one place to another. It helps reduce the human burden in their daily lives and activities. This device is commonly used by a large number of industries to transport physical products. Trolley is often used by those who organize and stock merchandise in retail stores restock. When used properly, trolley can protect people from having back injuries and other health problems that can result from lifting and carrying heavy loads. This platform trolley is intended for transporting of goods with a maximum nominal load of 250-300kg.

Excerpt from the Book
Description of the best design:
The Platform trolley or hand truck is a device that moves loads from one location to another location. From the best design, parts of a Platform trolley are identified by their purpose and location. The best design includes the platform board, this is where the goods that are to be carried are being placed on, described as the load carriage, that carries the load. Attached to the top of the platform is the handle; the handle also helps support and prevent the load from shifting backwards. And attached beneath the platform are the Rigid and swivel wheels. The both tires help with the movement and the direction of the trolley and to keep the trolley stable while it’s in use. (AHMAD, 2008)
