Basket, seat and handle 5

  1. Basket Most carts are metal, or metal and plastic. The baskets are shaped so the carts nest one inside the next.
  2. Handle It runs across the back of the cart. A coin lock, where there is one, is fixed to it.
  3. Child seat Folded shut, it is a shelf for small goods.
  4. Seat belt It fastens with a buckle.
  5. Coin lock You get the coin back when you return the cart. It must be locked to the next one.

Chassis and wheels 3

  1. Chassis The wheels are fixed to it from below.
  2. Front swivel casters Each wheel sits in a fork that turns. In Europe it is more common for all four wheels to swivel.
  3. Rear wheels Fixed on most United States carts. So they only roll straight ahead.

From the basket down to the wheels

Numbers 1 to 5 are the top of the cart: the wire basket, the handle you push, the child seat folded open at the back, its seat belt, and the coin lock on the handle. Numbers 6 to 8 are underneath: the chassis, the swivel casters at the front and the rear wheels.

  • Front and back wheels differ: a caster swivels, a fixed wheel only rolls straight.
  • Look for the chain: the coin lock links each cart to the one in front.

Questions and answers

What are the parts of a shopping trolley called?

Which wheels on a shopping cart swivel?

On most carts in the United States the front wheels are swivel casters and the rear wheels are fixed. In Europe it is more common for all four wheels to swivel.

How does the coin lock on a shopping cart work?

You put a coin or a token in the lock on the handle, which frees the cart from the row. When you bring the cart back and lock it to another cart, the coin is returned.

Why do shopping carts fit inside each other?

They are designed to nest in a line, so that many can be collected and moved at one time and they take up less space when stored.
