Working Karret Trolley is a small vehicle with two or four wheels that you push or pull to transport large or heavy objects on: a shopping trolley. The hospital is so overcrowded that some patients are being treated on trolleys in the corridors.

Trolleys are used in airports and some large railway stations for passengers to carry their luggage. Deposits are not refundable. A trolley can also be a tea-trolley. This is a small trolley used traditionally in the house for plates, cups, saucers and sandwiches and cakes for afternoon tea.
