What is a handrail

The term handrail is used for the shaped part of the railing on the escalators, railings or in the means of transport. It can be an integral part of the object to be carried, but more often it is a purpose-built component that is inseparably linked to the object. 
The surface of the handrail should be comfortable to touch, not slip between the fingers. Handrail on stairs or escalators will allow grasping with all hands, or more people. The handle is passive when we hold the large object and lift the small object. The handle also has no controls.
