Here are some more details about shopping carts:

 

– Shopping carts come in different sizes depending on their intended use. Large carts for supermarkets can hold a great deal of items, while smaller carts at convenience stores or drug stores have lesser capacity. 

 

– Materials used include plastic, metal and composite materials. Plastic carts are most common today as they are lightweight and durable. Metal carts were more common historically.

 

– Features include a handle at the back or front for pushing or pulling, a child seat area, storage basket underneath, wheels for mobility, and security locks to prevent theft. 

 

– Security locks are an important part of cart design. Most carts have mechanisms that lock the wheels when taken too far from the store, encouraging customers to return them for the next shopper. Some stores also use carts with locking mechanisms that require a coin deposit.

 

– Beyond regular shopping carts, some stores have specialty carts like kid-sized mini carts, carts with built-in baby seats, oversized carts for bulk shopping, and carts designed for use outside in parking lots.

 

– Shopping cart manufacturing is a specialized industry. Companies design, produce and distribute carts customized for retailer needs on a large scale worldwide.

 

– Cart ergonomics and wheel/bearing design have improved over the years to make pushing and steering heavy loads easier for customers.
