What is the role of an unpowered roller conveyor?

A roller conveyor is a device that uses rollers to transport products. It is generally powered by electricity. An unpowered roller conveyor does not rely on electricity, but on manpower or the weight of the object itself for transportation.

Unpowered roller conveyors play an important role in the field of logistics and warehousing. It can be used to transport items. When transporting items, workers can put the items on an unpowered roller conveyor, push the items, and transport the items to the warehouse along the direction of the roller conveyor. This method greatly saves manpower and improves work efficiency. In fact, this method of transporting items was discovered by humans many years ago. Before entering the industrial age, people had learned to use cylindrical objects to transport heavy objects. This cylindrical object is the trunk of a tree. Now, roller conveyors are generally made of metal materials.
